Page 15: Section 2: getting started

This document describes how to perform the setup, management, and maintenance of the UAP in Standalone Mode. For information about configuring the AP in Managed Mode by using the D‐Link Unified Wireless Switch, see the User Manual for the switch. Before you power on a new UAP, review the following sections to check required hardware and software components, client configurations, and compatibility issues. Make sure you have everything you need for a successful launch and test of your new or extended wireless network. The DWL‐6600AP and DWL‐8600AP are dual‐radio access points and support the IEEE 802.11a, 802.11b, 802.11g, and 802.11n modes. The DWL‐3600AP is a single‐radio access point and supports the IEEE 802.11b, IEEE 802.11g, and 802.11n (2.4 GHz) modes. This section contains the following topics: • “Administrator’s Computer Requirements” • “Wireless Client Requirements” • “Dynamic and Static IP Addressing on the AP” • “Installing the UAP” • “Basic Settings” • “Using the CLI to View the IP Address” • “Configuring the Ethernet Settings” • “Configuring IEEE 802.1X Authentication” • “Verifying the Installation” • “Configuring Security on the Wireless Access Point” To manage the UAP by using the Web interface or by using the CLI through Telnet or SSH, the AP needs an IP address. If you use VLANs or IEEE 802.1X Authentication (port security) on your network, you might need to configure additional settings on the AP before it can connect to the network. Note: The WLAN AP is not designed to function as a gateway to the Internet. To connect your WLAN to other LANs or the Internet, you need a gateway device. D-Link Unified Access Point Administrator’s Guide November 2011 Page 15...
Page 16: Administrator's computer requirements

Table 2: Requirements for the Administrator’s Computer Required Software or Component Description Serial or Ethernet Connection to the The computer used to configure the first access point must be Access Point connected to the access point by a serial cable or an Ethernet cable. Wireless Connection to the Network After initial configuration and launch of the first access point on your new wireless network, you can make subsequent configuration changes through the Administration Web pages using a wireless connection to the internal network. For wireless connection to the access point, your administration device will need Wi‐Fi capability similar to that of any wireless client: Portable or built‐in Wi‐Fi client adapter that supports one or more of the IEEE 802.11 modes in which you plan to run the access point. Wireless client software configured to associate with the UAP. Web Browser and Operating System Configuration and administration of the UAP is provided through a Web‐based user interface hosted on the access point. We recommend using one of the following supported Web browsers to access the access point Administration Web pages: • Microsoft® Internet Explorer® version 7.x or 8.x (with up‐to‐date patch level for either major version) • Mozilla® Firefox version 3.5 or later • Safari 5 and later versions The administration Web browser must have JavaScript™ enabled to support the interactive features of the administration interface. Security Settings Ensure that security is disabled on the wireless client used to initially configure the access point. D-Link Unified Access Point Administrator’s Guide November 2011 Page 16...
Page 17: Wireless client requirements

To connect to the access point, wireless clients need the software and hardware described in the following table. Table 3: Requirements for Wireless Clients Required Component Description Wi‐Fi Client Adapter Portable or built‐in Wi‐Fi client adapter that supports one or more of the IEEE 802.11 modes in which you plan to run the access point. Wireless Client Software Client software, such as Microsoft Windows Supplicant, configured to associate with the UAP. Client Security Settings Security should be disabled on the client used to do initial configuration of the access point. If the Security mode on the access point is set to anything other than plain text, wireless clients will need to set a profile to the authentication mode used by the access point and provide a valid username and password, certificate, or similar user identity proof. Security modes are Static WEP, IEEE 802.1X, WPA with RADIUS server, and WPA‐PSK. For information about configuring security on the access point, see “Virtual Access Point Settings” on page 70. Dynamic and Static IP Addressing on the AP When you power on the access point, the built‐in DHCP client searches for a DHCP server on the network in order to obtain an IP Address and other network information. If the AP does not find a DHCP server on the network, the AP continues to use its default Static IP Address (10.90.90.91) until you re‐assign it a new static IP address (and specify a static IP addressing policy) or until the AP successfully receives network information from a DHCP server. To change the connection type and assign a static IP address by using the CLI, see “Configuring the Ethernet Settings” on page 25 or, by using the Web UI, see “Ethernet Settings” on page 51. Caution! If you do not have a DHCP server on your internal network, and do not plan to use one, the first thing you must do after powering on the access point is change the connection type from DHCP to static IP. You can either assign a new static IP address to the AP or continue using the default address. We recommend assigning a new static IP address so that if you bring up another WLAN AP on the same network, the IP address for each AP will be unique. D-Link Unified Access Point Administrator’s Guide November 2011 Page 17...
Page 18: Recovering an ip address

Unified Access Point Administrator’s Guide Dynamic and Static IP Addressing on the AP Recovering an IP Address If you experience trouble communicating with the access point, you can recover a static IP address by resetting the AP configuration to the factory defaults (see “Resetting the Factory Default Configuration” on page 120), or you can get a dynamically assigned address by connecting the AP to a network that has a DHCP server. Discovering a Dynamically Assigned IP Address If you have access to the DHCP server on your network and know the MAC address of your AP, you can view the new IP address associated with the MAC address of the AP. If you do not have access to the DHCP server that assigned the IP address to the AP or do not know the MAC address of the AP, you might need to use the CLI to find out what the new IP address is. For information about how to discover a dynamically assigned IP address, see “Using the CLI to View the IP Address” on page 24. D-Link Unified Access Point Administrator’s Guide November 2011 Page 18...
Page 19: Installing the uap

Unified Access Point Administrator’s Guide Installing the UAP Installing the UAP To access the Administration Web UI, you enter the IP address of the AP into a Web browser. You can use the default IP address of the AP (10.90.90.91) to log on to the AP and assign a static IP address, or you can use a DHCP server on you network to assign network information to the AP. The DHCP client on the AP is enabled by default. To install the UAP, use the following steps: 1. Connect the AP to an administrative PC by using a LAN connection or a direct‐cable connection. • To use a LAN connection, connect one end of an Ethernet cable to the network port on the access point and the other end to the same hub where your PC is connected, as shown in the following figure. The hub or switch you use must permit broadcast signals from the access point to reach all other devices on the network. • To use a direct‐cable connection, connect one end of an Ethernet straight‐through or crossover cable to the network port on the access point and the other end of the cable to the Ethernet port on the PC, as shown in the following figure. You can also use a serial cable to connect the serial port on the AP to a serial port on the administrative computer. For initial configuration with a direct Ethernet connection and no DHCP server, be sure to set your PC to a static IP address in the same subnet as the default IP address on the access point. (The default IP address for the access point is 10.90.90.91.) If you use this method, you will need to reconfigure the cabling for subsequent startup and deployment of the access point so that the access point is no longer connected directly to the PC but instead is connected to the LAN (either by using a hub or directly). D-Link Unified Access Point Administrator’s Guide November 2011 Page 19...

2. Connect the power adapter to the power port on the back of the access point, and then plug the other end of the power cord into a power outlet. 3. Use your Web browser to log on to the UAP Administration Web pages. – If the AP did not acquire an IP address from a DHCP server on your network, enter 10.90.90.91 in the address field of your browser, which is the default IP address of the AP. – If you used a DHCP server on your network to automatically configure network information for the AP, enter the new IP address of the AP into the Web browser. – If you used a DHCP server and you do not know the new IP address of the AP, use the following procedures to obtain the information: a. Connect a serial cable from the administrative computer to the AP and use a terminal emulation program to access the command‐line interface (CLI). b. At the login prompt, enter for the user name and for the password. At the command admin admin prompt, enter get management. – The command output displays the IP address of the AP. Enter this address in the address field of your browser. For a more detailed explanation about how to log on to the CLI by using the console port, see “Using the CLI to View the IP Address” on page 24. 4. When prompted, enter for the user name and for the password, then click OK. admin admin D-Link Unified Access Point Administrator’s Guide November 2011 Page 20...

“Configuring the Ethernet Settings” on page 25 (CLI) or “Ethernet Settings” on page 51 (Web). 7. If your network uses VLANs, you might need to configure the management VLAN ID or untagged VLAN ID on the UAP in order for it to work with your network. For information about how to configure VLAN information, see “Configuring the Ethernet Settings” on page 25 (CLI) or “Ethernet Settings” on page 51 (Web). 8. If your network uses IEEE 802.1X port security for network access control, you must configure the 802.1X supplicant information on the AP. For information about how to configure the 802.1X user name and password, see “Configuring IEEE 802.1X Authentication” on page 27. Basic Settings From the Basic Settings page, you can view various information about the UAP, including IP and MAC address information, and configure the administrator password for the UAP. Table 4 describes the fields and configuration options on the Basic Settings page. Table 4: Basic Settings Page Field Description IP Address Shows the IP address assigned to the AP. This field is not editable on this page because the IP address is already assigned (either by DHCP, or statically through the Ethernet Settings page). IPv6 Address Shows the IPv6 address assigned to the AP. This field is not editable on this page because the IP address is already assigned (either by DHCPv6, or statically through the Ethernet Settings page). IPv6 Link Local Shows the IPv6 Link Local address, which is the IPv6 address used by the local physical Address link. The link local address is not configurable and is assigned by using the IPv6 Neighbor Discovery process. MAC Address Shows the MAC address of the AP. The address shown here is the MAC address associated with the management interface. This is the address by which the AP is known externally to other networks.

Enter the current administrator password. You must correctly enter the current password before you are able to change it. New Password Enter a new administrator password. The characters you enter are displayed as bullet characters to prevent others from seeing your password as you type. The administrator password must be an alphanumeric string of up to 8 characters. Do not use special characters or spaces. Note: As an immediate first step in securing your wireless network, we recommend that you change the administrator password from the default. Confirm New Re‐enter the new administrator password to confirm that you typed it as intended. Password Baud Rate Select a baud rate for the serial port connection. The baud rate on the AP must match the baud rate on the terminal or terminal emulator to connect to the AP command‐line interface (CLI) by using a serial (console) connection. The following baud rates are available: • 9600 • 19200 • 38400 • 57600 • 115200 System Name Enter a name for the AP. This name appears only on the Basic Settings page and is a name to identify the AP to the administrator. Use up to 64 alphanumeric characters, for example My AP. System Contact Enter the name, e‐mail address, or phone number of the person to contact regarding issues related to the AP. System Location Enter the physical location of the AP, for example Conference Room A. D-Link Unified Access Point Administrator’s Guide November 2011 Page 23...
Page 24: Connecting to the ap web interface by using the ipv6 address

Note: The following instructions and examples work with Microsoft Internet Explorer 7 (IE7) and might not work with other browsers. To connect to an IPv6 global address, add square brackets around the IPv6 address. For example, if the AP global IPv6 address is 2520::230:abff:fe00:2420, type the following address into the IE7 address field: http:// [2520::230:abff:fe00:2420]. To connect to the iPv6 link local address, replace the colons (:) with hyphens (‐), add the interface number preceded with an "s," then add ".ipv6‐literal.net." For example, if the AP link local address is fe80::230:abff:fe00:2420, and the Windows interface is defined as "%6," type the following address into the IE7 address field: http://fe80‐‐230‐abff‐fe00‐2420s6.ipv6‐literal.net. Using the CLI to View the IP Address The DHCP client on the UAP is enabled by default. If you connect the UAP to a network with a DHCP server, the AP automatically acquires an IP address. To manage the UAP by using the Administrator UI, you must enter the IP address of the access point into a Web browser. If a DHCP server on your network assigns an IP address to the UAP, and you do not know the IP address, use the following steps to view the IP address of the UAP: 1. Using a null‐modem cable, connect a VT100/ANSI terminal or a workstation to the console (serial) port. If you attached a PC, Apple, or UNIX workstation, start a terminal‐emulation program, such as HyperTerminal or TeraTerm. 2. Configure the terminal‐emulation program to use the following settings: • Baud rate: 115200 bps • Data bits: 8 • Parity: none • Stop bit: 1 • Flow control: none 3. Press the return key, and a login prompt should appear. The login name is admin. The default password is admin. After a successful login, the screen shows the (Access Point Name)# prompt.

Unified Access Point Administrator’s Guide Configuring the Ethernet Settings 4. At the login prompt, enter get management Information similar to the following prints to the screen. Configuring the Ethernet Settings The default Ethernet settings, which include DHCP and VLAN information, might not work for all networks. By default, the DHCP client on the UAP automatically broadcasts requests for network information. If you want to use a static IP address, you must disable the DHCP client and manually configure the IP address and other network information. The management VLAN is VLAN 1 by default. This VLAN is also the default untagged VLAN. If you already have a management VLAN configured on your network with a different VLAN ID, you must change the VLAN ID of the management VLAN on the access point. For information about using the Web interface to configure the Ethernet settings, see “Ethernet Settings” on page 51. You can also use the CLI to configure the Ethernet settings, which the following section describes. D-Link Unified Access Point Administrator’s Guide November 2011 Page 25...

Page 28: Verifying the installation

Verifying the Installation Make sure the access point is connected to the LAN and associate some wireless clients with the network. Once you have tested the basics of your wireless network, you can enable more security and fine‐tune the AP by modifying advanced configuration features. 1. Connect the access point to the LAN. • If you configured the access point and administrator PC by connecting both into a network hub, then your access point is already connected to the LAN. The next step is to test some wireless clients. • If you configured the access point by using a direct cable connection from your computer to the access point, do the following procedures: a. Disconnect the cable from the computer and the access point. b. Connect an Ethernet cable from the access point to the LAN. c. Connect your computer to the LAN by using an Ethernet cable or a wireless card. 2. Test LAN connectivity with wireless clients. Test the UAP by trying to detect it and associate with it from some wireless client devices. For information about requirements for these clients, see “Wireless Client Requirements” on page 17. 3. Secure and configure the access point by using advanced features. Once the wireless network is up and you can connect to the AP with some wireless clients, you can add in layers of security, create multiple virtual access points (VAPs), and configure performance settings. Note: The WLAN AP is not designed for multiple, simultaneous configuration changes. If more than one administrator is logged onto the Administration Web pages and making changes to the configuration, there is no guarantee that all configuration changes specified by multiple users will be applied. By default, no security is in place on the access point, so any wireless client can associate with it and access your LAN. An important next step is to configure security, as described in “Virtual Access Point Settings” on page 70. D-Link Unified Access Point Administrator’s Guide November 2011 Page 28...
Page 29: Configuring security on the wireless access point

Unified Access Point Administrator’s Guide Configuring Security on the Wireless Access Point Configuring Security on the Wireless Access Point You configure secure wireless client access by configuring security for each virtual access point (VAP) that you enable. You can configure up to 16 VAPs per radio that simulate multiple APs in one physical access point. By default, only one VAP is enabled. For each VAP, you can configure a unique security mode to control wireless client access. Each radio has 16 VAPs, with VAP IDs from 0‐15. By default, only VAP 0 on each radio is enabled. VAP0 has the following default settings: • VLAN ID: 1 • Broadcast SSID: Enabled • SSID: dlink1 • Security: None • MAC Authentication Type: None • Redirect Mode: None All other VAPs are disabled by default. The default SSID for VAPs 1 – 1 5 is "dlinkx" where x is the VAP ID. To prevent unauthorized access to the UAP, we recommend that you select and configure a security option other than None for the default VAP and for each VAP that you enable. For information about how to configure the security settings on each VAP, see “Virtual Access Point Settings” on page 70. D-Link Unified Access Point Administrator’s Guide November 2011 Page 29...

Page 32: Viewing events

Unified Access Point Administrator’s Guide Viewing Events Viewing Events The Events page shows real‐time system events on the AP such as wireless clients associating with the AP and being authenticated. To view system events, click the Events tab. Figure 3: Viewing Events From the Events page, you can perform the following tasks: • View the most recent, high‐level events generated by this AP. • Enable and configure persistent logging to write system event logs to non‐volatile memory so that the events are not erased when the system reboots. • Set a Severity Level to determine what category of log messages are displayed. • Set Depth to determine how many log messages are displayed in the Event log. • Enable a remote log relay host to capture all system events and errors in a Kernel Log. Note: The AP acquires its date and time information using the network time protocol (NTP). This data is reported in UTC format (also known as Greenwich Mean Time). You need to convert the reported time to your local time. For information on setting the network time protocol, see “” on page 106. Configuring Persistent Logging Options If the system unexpectedly reboots, log messages can be useful to diagnose the cause. However, log messages are erased when the system reboots unless you enable persistent logging. D-Link Unified Access Point Administrator’s Guide November 2011 Page 32...
Page 33: Figure 4: Persistent logging options

• 3 — e rror • 4 — w arning • 5 — n otice • 6 — i nfo • 7 — d ebug Depth You can store up to 128 messages in non‐volatile memory. Once the number you configure in this field is reached, the oldest log event is overwritten by the new log event. Note: To apply your changes, click Apply. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low. D-Link Unified Access Point Administrator’s Guide November 2011 Page 33...
Page 34: Configuring the log relay host for kernel messages

Unified Access Point Administrator’s Guide Viewing Events Configuring the Log Relay Host for Kernel Messages The Kernel Log is a comprehensive list of system events (shown in the System Log) and kernel messages such as error conditions, like dropping frames. You cannot view kernel log messages directly from the Administration Web UI for an AP. You must first set up a remote server running a syslog process and acting as a syslog log relay host on your network. Then, you can configure the UAP to send syslog messages to the remote server. Remote log server collection for AP syslog messages provides the following features: • Allows aggregation of syslog messages from multiple APs • Stores a longer history of messages than kept on a single AP • Triggers scripted management operations and alerts To use Kernel Log relaying, you must configure a remote server to receive the syslog messages. The procedure to configure a remote log host depends on the type of system you use as the remote host. Note: The syslog process will default to use port 514. We recommend keeping this default port. However; If you choose to reconfigure the log port, make sure that the port number you assign to syslog is not being used by another process. Enabling or Disabling the Log Relay Host on the Events Page To enable and configure Log Relaying on the Events page, set the Log Relay options as described in the following table, and then click Apply. Figure 5: Log Relay Host Table 8: Log Relay Host Field Description Relay Log Select Enabled to allow the UAP to send log messages to a remote host. Select Disabled to keep all log messages on the local system. Relay Host Specify the IP Address or DNS name of the remote log server. Relay Port Specify the Port number for the syslog process on the Relay Host. The default port is 514. D-Link Unified Access Point Administrator’s Guide November 2011 Page 34...

Page 38: Viewing associated wireless client information

To view the client stations associated with a particular access point, click the Client Associations tab. Figure 7: Viewing Client Association Information The associated stations are displayed along with information about packet traffic transmitted and received for each station. Table 10 describes the fields on the Client Associations page. Table 10: Associated Clients Field Description Network Shows which VAP the client is associated with. For example, an entry of wlan0vap2 means the client is associated with Radio 1, VAP 2. An entry of wlan0 means the client is associated with VAP 0 on Radio 1. An entry of wlan1 means the client is associated with VAP 0 on Radio 2. Station Shows the MAC address of the associated wireless client. Status The Authenticated and Associated Status shows the underlying IEEE 802.11 authentication and association status, which is present no matter which type of security the client uses to connect to the AP. This status does not show IEEE 802.1X authentication or association status. Some points to keep in mind with regard to this field are: • If the AP security mode is None or Static WEP, the authentication and association status of clients showing on the Client Associations page will be in line with what is expected; that is, if a client shows as authenticated to the AP, it will be able to transmit and receive data. (This is because Static WEP uses only IEEE 802.11 authentication.) • If the AP uses IEEE 802.1X or WPA security, however, it is possible for a client association to show on this page as authenticated (via the IEEE 802.11 security) but actually not be authenticated to the AP via the second layer of security. From Station Shows the number of packets and bytes received from the wireless client and the number of packets and bytes that were dropped after being received. To Station Shows the number of packets and bytes transmitted from the AP to the wireless client and the number of packets and bytes that were dropped upon transmission.

Page 39: Viewing tspec client associations

Unified Access Point Administrator’s Guide Viewing TSPEC Client Associations Viewing TSPEC Client Associations The TSPEC Client Association Status and Statistics page provides some basic information about the client associations status and a real‐time display of the transmit and receive statistics for the TSPEC clients. All transmit and receive statistics shown are totals since the client association started. A TSPEC is a traffic specification that is sent from a QoS‐capable wireless client to an AP requesting a certain amount of network access for the traffic stream (TS) it represents. A traffic stream is a collection of data packets identified by the wireless client as belonging to a particular user priority. An example of a voice traffic stream is a Wi‐Fi CERTIFIED™ telephone handset that marks its codec‐generated data packets as voice priority traffic. An example of a video traffic stream is a video player application on a wireless laptop that prioritizes a video conference feed from a corporate server. To view TSPEC client association statistics, click the TSPEC Client Associations tab.

Page 41: Link integrity monitoring

Unified Access Point Administrator’s Guide Viewing Rogue AP Detection Link Integrity Monitoring The UAP provides link integrity monitoring to continually verify its connection to each associated client. To do this, the AP sends data packets to clients every few seconds when no other traffic is passing. This allows the AP to detect when a client goes out of range, even during periods when no normal traffic is exchanged. The client connection drops off the list within 300 seconds if these data packets are not acknowledged, even if no disassociation message is received. Viewing Rogue AP Detection The status page to view Rogue AP Detection information provides real‐time statistics for all APs within range of the AP on which you are viewing the Administration Web pages. When AP detection is enabled, the radio will periodically switch from its operating channel to scan other channels within the same band. Click Refresh to update the screen and display the most current information. The Rogue AP Detection page contains the following two lists: • Detected Rogue AP List — Lists all APs within range of the AP that have not been acknowledged as known APs. • Known AP List — Lists all APs within range of the AP that have been acknowledged as known APs either by clicking the Grant button associated with an AP in the Detected Rogue AP List or by appearing in an imported AP list. To view information about other access points on the wireless network, click the Rogue AP Detection tab.

Mode The Mode defines the Physical Layer (PHY) standard the radio uses. Note: The modes available depend on the country code setting and the radio selected. Select one of the following modes for radio 1 (DWL‐6600AP and DWL‐8600AP only): • IEEE 802.11a is a PHY standard that specifies operating in the 5 GHz U‐NII band using orthogonal frequency division multiplexing (OFDM). It supports data rates ranging from 6 to 54 Mbps. • IEEE 802.11a/n operates in the 5 GHz ISM band and includes support for both 802.11a and 802.11n devices. IEEE 802.11n is an extension of the 802.11 standard that includes multiple‐input multiple‐output (MIMO) technology. IEEE 802.11n supports data ranges of up to 248 Mbps and nearly twice the indoor range of 802.11 b, 802.11g, and 802.11a. • 5 GHz IEEE 802.11n is the recommended mode for networks with 802.11n devices that operate in the 5 GHz frequency that do not need to support 802.11a devices. IEEE 802.11n can achieve a higher throughput when it does not need to be compatible with legacy devices (802.11a). Select one of the following modes for radio 2: • IEEE 802.11b/g operates in the 2.4 GHz ISM band. IEEE 802.11b is an enhancement of the initial 802.11 PHY to include 5.5 Mbps and 11 Mbps data rates. It uses direct sequence spread spectrum (DSSS) or frequency hopping spread spectrum (FHSS) as well as complementary code keying (CCK) to provide the higher data rates. It supports data rates ranging from 1 to 11 Mbps. IEEE 802.11g is a higher speed extension (up to 54 Mbps) to the 802.11b PHY. It uses orthogonal frequency division multiplexing (OFDM). It supports data rates ranging from 1 to 54 Mbps. • IEEE 802.11b/g/n operates in the 2.4 GHz ISM band and includes support for 802.11b, 802.11g, and 802.11n devices. • 2.4 GHz IEEE 802.11n is the recommended mode for networks with 802.11n devices that operate in the 2.4 GHz frequency that do not need to support 802.11b/g devices. IEEE 802.11n can achieve a higher throughput when it does not need to be compatible with legacy devices (802.11b/g). D-Link Unified Access Point Administrator’s Guide November 2011 Page 55...

To enable Station Isolation, select the check box directly beside it. When Station Isolation is disabled, wireless clients can communicate with one another normally by sending traffic through the AP. When Station Isolation is enabled, the AP blocks communication between wireless clients on the same radio and VAP. The AP still allows data traffic between its wireless clients and wired devices on the network, across a WDS link, and with other wireless clients associated with a different VAP, but not among wireless clients associated with the same VAP. Note: On dual‐radio APs, Station Isolation does not block communication between Radio 1 and Radio 2, even if the VAP configuration on each radio is the same. AeroScout™ AeroScout Engine support provides location‐based services for wireless networks. Specify Engine Protocol whether to enable support for the AeroScout protocol. Support Options are Enabled or Disabled. The default is Disabled. When enabled, Aeroscout devices are recognized and data is sent to an Aeroscout Engine (AE) for analysis. The AE determines the geographical location of 802.11‐capable devices, such as STAs, APs, and AeroScout’s line of 802.11‐enabled RFID devices, or tags. The AE communicates with APs that support the AE protocol in order to collect information about the RF devices detected by the APs. Using the AE protocol, D‐Link supports direct communication between AE and the APs. When operating in managed mode, the AE is configured with the IP address of the managed access points from which it collects information. The Wireless Switch cannot communicate with the AE. For more information about the AeroScout protocol, see “Enabling AeroScout™ Engine Support” on page 57. Note: Only AeroScout tag hardware of types T2 and T3 are explicitly supported. Other tag models are also supported only if their implementation of the AeroScout protocol conforms to the AeroScout Engine ‐ Access Point Interface Specification, version 2.1. Note: AeroScout tags operate only in 802.11 b/g mode. Therefore, network administrators who use the AeroScout tags must configure at least one radio on APs that are expected to detect tags in either 802.11b/g or 802.11b/g/n mode. The radios configured in 2.4 GHz IEEE 802.11 mode or any of the 5GHZ modes cannot detect AeroScout tags. Note: The AE protocol allows access points to mark detected APs as rogue devices. The D‐ Link APs do not support this feature and never report detected APs as rogues. D-Link Unified Access Point Administrator’s Guide November 2011 Page 56...

Unified Access Point Administrator’s Guide Wireless Settings Note: After you configure the wireless settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low. Using the 802.11h Wireless Mode For 802.11a radios, if the regulatory domain requires radar detection on the channel, the Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC) features of 802.11h are automatically activated. There are a number of key points about the IEEE 802.11h standard: • 802.11h only works for the 802.11a band. It is not required for 802.11b or 802.11g. • If you are operating in an 802.11h enabled domain, the AP attempts to use the channel you assign. If the channel has been blocked by a previous radar detection, or if the AP detects a radar on the channel, then the AP automatically selects a different channel. • When 802.11h is enabled, the AP will not be operational in the 5GHz band for at least 60 seconds due to radar scanning. • Setting up WDS links may be difficult when 802.11h is operational. This is because the operating channels of the two APs on the WDS link may keep changing depending on channel usage and radar interference. WDS will only work if both the APs operate on the same channel. For more information on WDS, see “Configuring Load Balancing” on page 88. Enabling AeroScout™ Engine Support The AeroScout Engine (AE) is a software platform produced by AeroScout Inc. for location‐based services. The AE can determine the physical location of 802.11‐capable AeroScout devices. The AE communicates with APs that have the AE protocol enabled in order to collect information about the RF devices detected by the APs. The DWS‐4000 Series switch supports only direct communication between the AE and the APs. When operating in managed mode, the AE is configured with the IP address of the managed access points from which it collects information. The DWS‐4000 Series switch does not communicate with the AE. AeroScout tags operate only in 802.11b/g mode. Therefore, network administrators who use the AeroScout tags must configure at least one radio on APs that are expected to detect tags in either 802.11b/g or 802.11b/g/n mode. The radios configured in 2.4 GHz IEEE 802.11n mode or any of the 5 GHz modes cannot detect AeroScout tags. D-Link Unified Access Point Administrator’s Guide November 2011 Page 57...
Page 58: Modifying radio settings

Unified Access Point Administrator’s Guide Modifying Radio Settings Note: The following notes apply to AeroScout product and protocol support: • D‐Link does not sell AeroScout products. Contact AeroScout for AeroScout hardware, software or deployment information. • The AE protocol does not support any authentication or encryption between the AE server and the access point. • The AE protocol requires radios to operate in promiscuous mode. This means that the AP receives and processes all packets detected by the radios, as opposed to processing only packets destined to the APs BSSID. This can affect AP throughput. Modifying Radio Settings Radio settings directly control the behavior of the radio devices in the AP and its interaction with the physical medium; that is, how and what type of electromagnetic waves the AP emits. To specify radio settings, click the Radio tab in the Manage section. Different settings display depending on the mode you select. All settings are described in Table 19 on page 60.

Select one of the following options: • Yes — T he AP transmits data using a 400 ns guard Interval when communicating with clients that also support the short guard interval. • No — T he AP transmits data using an 800 ns guard interval. STBC Mode This field is available only if the selected radio mode includes 802.11n. Space Time Block Coding (STBC) is an 802.11n technique intended to improve the reliability of data transmissions. The data stream is transmitted on multiple antennas so the receiving system has a better chance of detecting at least one of the data streams. Select one of the following options: • On — T he AP transmits the same data stream on multiple antennas at the same time. • Off — T he AP does not transmits the same data on multiple antennas.

Note: This setting does not affect the ability of the client to associate with the AP. Beacon Interval Beacon frames are transmitted by an AP at regular intervals to announce the existence of the wireless network. The default behavior is to send a beacon frame once every 100 milliseconds (or 10 per second). Enter a value from 20 to 2000 milliseconds. DTIM Period Specify a DTIM period from 1 to 255 beacons. The Delivery Traffic Information Map (DTIM) message is an element included in some Beacon frames. It indicates which client stations, currently sleeping in low‐power mode, have data buffered on the AP awaiting pick‐up. The DTIM period you specify indicates how often the clients served by this AP should check for buffered data still on the AP awaiting pickup. The measurement is in beacons. For example, if you set this field to 1, clients will check for buffered data on the AP at every beacon. If you set this field to 10, clients will check on every 10th beacon. Fragmentation Specify a number between 256 and 2,346 to set the frame size threshold in bytes. Threshold The fragmentation threshold is a way of limiting the size of packets (frames) transmitted over the network. If a packet exceeds the fragmentation threshold you set, the fragmentation function is activated and the packet is sent as multiple 802.11 frames. If the packet being transmitted is equal to or less than the threshold, fragmentation is not used. Setting the threshold to the largest value (2,346 bytes) effectively disables fragmentation. Fragmentation plays no role when Aggregation is enabled. Fragmentation involves more overhead both because of the extra work of dividing up and reassembling of frames it requires, and because it increases message traffic on the network. However, fragmentation can help improve network performance and reliability if properly configured. Sending smaller frames (by using lower fragmentation threshold) might help with some interference problems; for example, with microwave ovens. By default, fragmentation is off. We recommend not using fragmentation unless you suspect radio interference. The additional headers applied to each fragment increase the overhead on the network and can greatly reduce throughput.

• Rates are expressed in megabits per second. • Supported Rate Sets indicate rates that the AP supports. You can check multiple rates (click a check box to select or de‐select a rate). The AP will automatically choose the most efficient rate based on factors like error rates and distance of client stations from the AP. • Basic Rate Sets indicate rates that the AP will advertise to the network for the purposes of setting up communication with other APs and client stations on the network. It is generally more efficient to have an AP broadcast a subset of its supported rate sets.

TSPEC Video ACM Regulates mandatory admission control for the video access category. The options are: Mode • On — A station is required to send a TSPEC request for bandwidth to the AP before sending or receiving a video traffic stream. The AP responds with the result of the request, which includes the allotted medium time if the TSPEC was admitted. • Off — A station can send and receive video priority traffic without requiring an admitted TSPEC; the AP ignores video TSPEC requests from client stations.

Page 65: Configuring radio and vap scheduler

Unified Access Point Administrator’s Guide Configuring Radio and VAP Scheduler Configuring Radio and VAP Scheduler The Radio and VAP scheduler is a standalone DWL‐x600AP feature. To configure the Radio and VAP scheduler, select the Scheduler tab in the Manage section. The Radio and VAP Scheduler allows you to configure a rule with a specific time interval for VAPs or radios to be operational, thereby automating the enabling or disabling of the VAPs and Radios. One of the ways you can use this feature is to schedule radios to operate only during the office working hours in order to achieve security and reduce power consumption. You can also use the Scheduler to allow access to VAPs for wireless clients only during specific times of day. Each rule specifies the start time, end time and day (or days) of the week the radio or VAP can be operational. The rules are periodic in nature and are repeated every week. A valid rule must contain all of the following parameters: • Days of the Week • Start Time (hour and minutes) • End Time (hour and minutes) Only valid rules are added to the profile. Up to 16 rules are grouped together to form a scheduling profile. Any two periodic rules time entries belonging to the same profile must not overlap. The time granularity for the schedules is one minute. The DWL‐x600AP supports up to 16 profiles.

Provides additional information about the status. The reason can be one or more of the following: • IsActive – Operational status is up. • ConfigDown – Operational status is down because global configuration is disabled. • TimeNotSet – Operational status is down because the AP time has not been set, either manually or by specifying an NTP server to use. • ManagedMode– Operational status is down because the AP is in managed mode. Scheduler Profile The Scheduler profile defines the list of profiles names that can be associated to the VAP or Radio configuration. Rules are associated with a named scheduler profile. You can define up to 16 scheduler profile names. By default, no profiles are created. The profile name can be up to 32 alphanumeric characters. Click Add to add the profile name. Each scheduler profile may have up to 16 periodic rules. The list of parameters for Rule Configuration each periodic rule are described below. Select Profile Select the profile name from the menu.

Unified Access Point Administrator’s Guide Scheduler Association Settings Scheduler Association Settings For a Scheduler profile to take effect, you must associate it with at least one radio or VAP interface. To associate the Scheduler profiles, select the Scheduler Association tab in the Manage section. By default, there are no Scheduler profiles created, so no profile is associated to any radio or VAP. The Scheduler profile needs to be explicitly associated to a radio or VAP configuration. Only one Scheduler profile can be associated to any radio or VAP configuration; however, a single profile can be associated to multiple radios or VAPs. If the Scheduler profile associated with a VAP or radio is deleted, then the associated profile to the VAP or radio is removed implicitly. If the radio is operationally disabled, then all the VAPs associated to that radio are also operationally disabled irrespective of the VAP configuration.

Page 70: Virtual access point settings

Unified Access Point Administrator’s Guide Virtual Access Point Settings Virtual Access Point Settings To change VAP 0 or to enable and configure additional VAPs, select the VAP tab in the Manage section. VAPs segment the wireless LAN into multiple broadcast domains that are the wireless equivalent of Ethernet VLANs. VAPs simulate multiple APs in one physical AP. Each radio supports up to 16 VAPs. For each VAP, you can customize the security mode to control wireless client access. Each VAP can also have a unique SSID. Multiple SSIDs make a single AP look like two or more APs to other systems on the network. By configuring VAPs, you can maintain better control over broadcast and multicast traffic, which affects network performance. You can configure each VAP to use a different VLAN, or you can configure multiple VAPs to use the same VLAN, whether the VLAN is on the same radio or on a different radio. VAP0, which is always enabled on both radios, is assigned to the default VLAN 1. The AP adds VLAN ID tags to wireless client traffic based on the VLAN ID you configure on the VAP page or by using the RADIUS server assignment. If you use an external RADIUS server, you can configure multiple VLANs on each VAP. The external RADIUS server assigns wireless clients to the VLAN when the clients associate and authenticate. You can configure up to four global IPv4 or IPv6 RADIUS servers. One of the servers always acts as a primary while the others act as backup servers. The network type (IPv4 or IPv6) and accounting mode are common across all configured RADIUS servers. You can configure each VAP to use the global RADIUS server settings, which is the default, or you can configure a per‐VAP RADIUS server set. You can also configure separate RADIUS server settings for each VAP. For example, you can configure one VAP to use an IPv6 RADIUS server while other VAPs use the global IPv4 RADIUS server settings you configure. If wireless clients use a security mode that does not communicate with the RAIDUS server, or if the RADIUS server does not provide the VLAN information, you can assign a VLAN ID to each VAP. The AP assigns the VLAN to all wireless clients that connect to the AP through that VAP. Note: Before you configure VLANs on the AP, be sure to verify that the switch and DHCP server the AP uses can support IEEE 802.1Q VLAN encapsulation. To set up multiple VAPs, click Manage > VAP.

Page 71: Figure 20: Setting up virtual access points

Virtual Access Point Settings Figure 20: Setting Up Virtual Access Points Table 22 describes the fields and configuration options on the VAP page. Table 22: Virtual Access Point Settings Field Description RADIUS IP Address Specify the IP version that the RADIUS server uses. Type You can toggle between the address types to configure IPv4 and IPv6 global RADIUS address settings, but the AP contacts only the RADIUS server or servers for the address type you select in this field. RADIUS IP Address Enter the IPv4 or IPv6 address for the primary global RADIUS server. By default, each VAP uses the global RADIUS settings that you define for the AP at the top of the VAP page. RADIUS IPv6 Address When the first wireless client tries to authenticate with the AP, the AP sends an authentication request to the primary server. If the primary server responds to the authentication request, the AP continues to use this RADIUS server as the primary server, and authentication requests are sent to the address you specify. If the IPv4 RADIUS IP Address Type option is selected in the previous field, enter the IP address of the RADIUS server that all VAPs use by default, for example 192.168.10.23. If the IPv6 RADIUS IP Address Type option is selected, enter the IPv6 address of the primary global RADIUS server, for example 2001:0db8:1234::abcd. RADIUS IP or IPv6 Enter up to three IPv4 or IPv6 addresses to use as the backup RADIUS servers. The field Address 1 – 3 label is RADIUS IP Address when the IPv4 RADIUS IP Address Type option is selected and RADIUS IPv6 Address when the IPv6 RADIUS IP Address Type option is selected. If authentication fails with the primary server, each configured backup server is tried in sequence. The IPv4 or IPv6 address must be valid in order for the AP to attempt to contact the server.

• To enable the specified network, select the Enabled option beside the appropriate VAP. • To disable the specified network, clear the Enabled option beside the appropriate VAP. If you disable the specified network, you will lose the VLAN ID you entered. VLAN ID When a wireless client connects to the AP by using this VAP, the AP tags all traffic from the wireless client with the VLAN ID you enter in this field unless you enter the untagged VLAN ID or use a RADIUS server to assign a wireless client to a VLAN. The range for the VLAN ID is 1 – 4 094. If you use RADIUS‐based authentication for clients, you can optionally add the following attributes to the appropriate file in the RADIUS or AAA server to configure a VLAN for the client: • “Tunnel‐Type” • “Tunnel‐Medium‐Type” • “Tunnel‐Private‐Group‐ID” The RADIUS‐assigned VLAN ID overrides the VLAN ID you configure on the VAP page. You configure the untagged and management VLAN IDs on the Ethernet Settings page. For more information, see “Ethernet Settings” on page 51. SSID Enter a name for the wireless network. The SSID is an alphanumeric string of up to 32 characters. You can use the same SSID for multiple VAPs, or you can choose a unique SSID for each VAP. Note: If you are connected as a wireless client to the same AP that you are administering, resetting the SSID will cause you to lose connectivity to the AP. You will need to reconnect to the new SSID after you save this new setting. D-Link Unified Access Point Administrator’s Guide November 2011 Page 72...

The drop‐down menu for this feature allows you to select the type of MAC Type Authentication to use: • Disabled: Do not use MAC Authentication. • Local: Use the MAC Authentication list that you configure on the MAC Authentication page. • RADIUS: Use the MAC Authentication list on the external RADIUS server. For more information about MAC Authentication, see “Controlling Access by MAC Authentication” on page 85. Redirect Mode Enable the HTTP redirect feature to redirect wireless clients to a custom Web page. When redirect mode is enabled, the user will be redirected to the URL you specify after the wireless client associates with an AP and the user opens a Web browser on the client to access the Internet. The custom Web page must be located on an external Web server and might contain information such as the company logo and network usage policy. Note: The wireless client is redirected to the external Web server only once while it is associated with the AP. Redirect URL Specify the URL where the Web browser is to be redirected after the wireless client associates with the AP and sends HTTP traffic.

Page 74: None (plain-text)

None (Plain‐text) If you select None as your security mode, no further options are configurable on the AP. This mode means that any data transferred to and from the UAP is not encrypted.This security mode can be useful during initial network configuration or for problem solving, but it is not recommended for regular use on the Internal network because it is not secure. Static WEP Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks. All wireless stations and APs on the network are configured with a static 64‐bit (40‐bit secret key + 24‐bit initialization vector (IV)) or 128‐bit (104‐bit secret key + 24‐bit IV) Shared Key for data encryption. Static WEP is not the most secure mode available, but it offers more protection than setting the security mode to None (Plain‐text) as it does prevent an outsider from easily sniffing out unencrypted wireless traffic. WEP encrypts data moving across the wireless network based on a static key. (The encryption algorithm is a stream cipher called RC4.) Table 23: Static WEP Field Description Transfer Key Index Select a key index from the drop‐down menu. Key indexes 1 through 4 are available. The default is 1. The Transfer Key Index indicates which WEP key the AP will use to encrypt the data it transmits. Key Length Specify the length of the key by clicking one of the radio buttons: • 64 bits • 128 bits Key Type Select the key type by clicking one of the radio buttons: • ASCII • Hex D-Link Unified Access Point Administrator’s Guide November 2011 Page 74...

• Hex — I ncludes digits 0 to 9 and the letters A to F. Use the same number of characters for each key as specified in the Characters Required field. These are the RC4 WEP keys shared with the stations using the AP. Each client station must be configured to use one of these same WEP keys in the same slot as specified here on the AP. Characters Required: The number of characters you enter into the WEP Key fields is determined by the Key length and Key type you select. For example, if you use 128‐bit ASCII keys, you must enter 26 characters in the WEP key. The number of characters required updates automatically based on how you set Key Length and Key Type. Authentication The authentication algorithm defines the method used to determine whether a client station is allowed to associate with an AP when static WEP is the security mode. Specify the authentication algorithm you want to use by choosing one of the following options: • Open System authentication allows any client station to associate with the AP whether that client station has the correct WEP key or not. This algorithm is also used in plaintext, IEEE 802.1X, and WPA modes. When the authentication algorithm is set to Open System, any client can associate with the AP. Note: Just because a client station is allowed to associate does not ensure it can exchange traffic with an AP. A station must have the correct WEP key to be able to successfully access and decrypt data from an AP, and to transmit readable data to the AP. • Shared Key authentication requires the client station to have the correct WEP key in order to associate with the AP. When the authentication algorithm is set to Shared Key, a station with an incorrect WEP key will not be able to associate with the AP. • Both Open System and Shared Key. When you select both authentication algorithms: – Client stations configured to use WEP in shared key mode must have a valid WEP key in order to associate with the AP. – Client stations configured to use WEP as an open system (shared key mode not enabled) will be able to associate with the AP even if they do not have the correct WEP key.

• On some wireless client software, you can configure multiple WEP keys and define a client station “transfer key index”, and then set the stations to encrypt the data they transmit using different keys. This ensures that neighboring APs cannot decode each other’s transmissions. • You cannot mix 64‐bit and 128‐bit WEP keys between the access point and its client stations. IEEE 802.1X IEEE 802.1X is the standard defining port‐based authentication and infrastructure for doing key management. Extensible Authentication Protocol (EAP) messages sent over an IEEE 802.11 wireless network using a protocol called EAP Encapsulation Over LANs (EAPOL). IEEE 802.1X provides dynamically‐generated keys that are periodically refreshed. An RC4 stream cipher is used to encrypt the frame body and cyclic redundancy checking (CRC) of each 802.11 frame. This mode requires the use of an external RADIUS server to authenticate users. The AP requires a RADIUS server capable of EAP, such as the Microsoft Internet Authentication Server. To work with Windows clients, the authentication server must support Protected EAP (PEAP) and MSCHAP V2. You can use any of a variety of authentication methods that the IEEE 802.1X mode supports, including certificates, Kerberos, and public key authentication. You must configure the client stations to use the same authentication method the AP uses. Table 24: IEEE 802.1X Field Description Use Global RADIUS By default each VAP uses the global RADIUS settings that you define for the AP at the top Server Settings of the VAP page. However, you can configure each VAP to use a different set of RADIUS servers. To use the global RADIUS server settings, make sure the check box is selected. To use a separate RADIUS server for the VAP, clear the check box and enter the RADIUS server IP address and key in the following fields.

Page 81: Configuring the wireless distribution system (wds)

Unified Access Point Administrator’s Guide Configuring the Wireless Distribution System (WDS) Configuring the Wireless Distribution System (WDS) The Wireless Distribution System (WDS) allows you to connect multiple UAPs. With WDS, APs communicate with one another without wires in a standardized way. This capability is critical in providing a seamless experience for roaming clients and for managing multiple wireless networks. It can also simplify the network infrastructure by reducing the amount of cabling required. You can configure the AP in point‐to‐point or point‐ to‐multipoint bridge mode based on the number of links to connect. In the point‐to‐point mode, the AP accepts client associations and communicates with wireless clients and other repeaters. The AP forwards all traffic meant for the other network over the tunnel that is established between the APs. The bridge does not add to the hop count. It functions as a simple OSI layer 2 network device. In the point‐to‐multipoint bridge mode, one AP acts as the common link between multiple APs. In this mode, the central AP accepts client associations and communicates with the clients and other repeaters. All other APs associate only with the central AP that forwards the packets to the appropriate wireless bridge for routing purposes. The UAP can also act as a repeater. In this mode, the AP serves as a connection between two APs that might be too far apart to be within cell range. When acting as a repeater, the AP does not have a wired connection to the LAN and repeats signals by using the wireless connection. No special configuration is required for the AP to function as a repeater, and there are no repeater mode settings. Wireless clients can still connect to an AP that is operating as a repeater. Note: When you move an AP from Standalone Mode to Managed Mode, WDS is disabled. In Managed Mode, you configure the AP by using the D‐Link Unified Wireless Switch. The Administrator UI, as well as Telnet, SSH, and SNMP access are disabled when the AP is in Managed Mode. To specify the details of traffic exchange from this access point to others, click the WDS tab. D-Link Unified Access Point Administrator’s Guide November 2011 Page 81...
Page 82: Figure 21: Configuring wds settings

Unified Access Point Administrator’s Guide Configuring the Wireless Distribution System (WDS) Figure 21: Configuring WDS Settings Before you configure WDS on the AP, note the following guidelines: • When using WDS, be sure to configure WDS settings on both APs participating in the WDS link. • You can have only one WDS link between any pair of APs. That is, a remote MAC address may appear only once on the WDS page for a particular AP. • Both APs participating in a WDS link must be on the same Radio channel and using the same IEEE 802.11 mode. (See “Modifying Radio Settings” on page 58 for information on configuring the Radio mode and channel.) • When 802.11h is operational, setting up two WDS links can be difficult. See “Using the 802.11h Wireless Mode” on page 57. • If you use WPA encryption on the WDS link over radio 1, VAP0 of radio 1 must use WPA Personal or WPA Enterprise as the security mode. If you use WPA on a WDS link over radio 2, VAP0 of radio 2 must use WPA Personal or WPA Enterprise as the security mode. D-Link Unified Access Point Administrator’s Guide November 2011 Page 82...

Description Spanning Tree Spanning Tree Protocol (STP) prevents switching loops. STP is recommended if you Mode configure WDS links. Select Enabled to use STP Select Disabled to turn off STP links (not recommended) Radio For each WDS link on a two‐radio AP, select Radio One or Radio Two. The rest of the settings for the link apply to the radio selected in this field. The read‐only Local Address will change depending on which Radio you select in this field. Note: This field is not available on the DWL‐3600AP. Local Address Indicates the MAC addresses for this AP. For each WDS link on a two‐radio AP, the Local Address reflects the MAC address for the internal interface on the selected radio (Radio One on wlan0 or Radio Two on wlan1). Remote Address Specify the MAC address of the destination AP; that is, the AP on the other end of the WDS link to which data will be sent or handed‐off and from which data will be received. Click the drop‐down arrow to the right of the Remote Address field to see a list of all the available MAC Addresses and their associated SSIDs on the network. Select the appropriate MAC address from the list. NOTE: The SSID displayed in the drop‐down list is simply to help you identify the correct MAC Address for the destination AP. This SSID is a separate SSID to that which you set for the WDS link. The two do not (and should not) be the same value or name. Encryption You can use no encryption, WEP, or WPA (PSK) on the WDS link. If you are unconcerned about security issues on the WDS link you may decide not to set any type of encryption. Alternatively, if you have security concerns you can choose between Static WEP and WPA (PSK). In WPA (PSK) mode, the AP uses WPA2‐PSK with CCMP (AES) encryption over the WDS link. NOTE: In order to configure WPA‐PSK on any WDS link, VAP0 of the selected radio must be configured for WPA‐PSK or WPA‐Enterprise. If you select None as your preferred WDS encryption option, you will not be asked to fill in any more fields on the WDS page. All data transferred between the two APs on the WDS link will be unencrypted. Note: To disable a WDS link, you must remove the value configured in the Remote Address field.

A – Z . If you selected HEX, enter hexadecimal digits (any combination of 0 – 9 and a – f or A – F ). These are the RC4 encryption keys shared with the stations using the AP. WPA/PSK on WDS Links Table 29 describes the additional fields that appear when you select WPA/PSK as the encryption type. Note: To configure WPA‐PSK on any WDS link, VAP0 of the selected radio must be configured for WPA‐ PSK or WPA‐Enterprise. Table 29: WPA/PSK on WDS Links Field Description Encryption WPA (PSK) SSID Enter an appropriate name for the new WDS link you have created. This SSID should be different from the other SSIDs used by this AP. However, it is important that the same SSID is also entered at the other end of the WDS link. If this SSID is not the same for both APs on the WDS link, they will not be able to communicate and exchange data. The SSID can be any alphanumeric combination. Enter a unique shared key for the WDS bridge. This unique shared key must also be entered for the AP at the other end of the WDS link. If this key is not the same for both APs, they will not be able to communicate and exchange data. The WPA‐PSK key is a string of at least 8 characters to a maximum of 63 characters. Acceptable characters include upper and lower case alphabetic letters, the numeric digits, and special symbols such as @ and #.

Page 85: Controlling access by mac authentication

Unified Access Point Administrator’s Guide Controlling Access by MAC Authentication Note: After you configure the WDS settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low. Controlling Access by MAC Authentication A Media Access Control (MAC) address is a hardware address that uniquely identifies each node of a network. All IEEE 802 network devices share a common 48‐bit MAC address format, usually displayed as a string of 12 hexadecimal digits separated by colons, for example 00:DC:BA:09:87:65 . Each wireless network interface card (NIC) used by a wireless client has a unique MAC address. You can use the Administrator UI on the AP or use an external RADIUS server to control access to the network through the AP based on the MAC address of the wireless client. This feature is called MAC Authentication or MAC Filtering. To control access, you configure a global list of MAC addresses locally on the AP or on an external RADIUS server. Then, you set a filter to specify whether the clients with those MAC addresses are allowed or denied access to the network. When a wireless client attempts to associate with an AP, the AP looks up the MAC address of the client in the local Stations List or on the RADIUS server. If it is found, the global allow or deny setting is applied. If it is not found, the opposite is applied. On the VAP page, the MAC Authentication Type setting controls whether the AP uses the station list configured locally on the MAC Authentication page or the external RADIUS server. The Allow/Block filter setting on the MAC Authentication page determines whether the clients in the station list (local or RADIUS) can access the network through the AP. For more information about setting the MAC authentication type, see “Virtual Access Point Settings” on page 70. Configuring a MAC Filter and Station List on the AP The MAC Authentication page allows you to control access to UAP based on MAC addresses. Based on how you set the filter, you can allow only client stations with a listed MAC address or deny access to the stations listed. When you enable MAC Authentication and specify a list of approved MAC addresses, only clients with a listed MAC address can access the network. If you specify MAC addresses to deny, all clients can access the network except for the clients on the deny list. To enable filtering by MAC address, click the MAC Authentication tab.

Table 30 describes the fields and configuration options available on the MAC Authentication page Table 30: MAC Authentication Field Description Filter To set the MAC Address Filter, select one of the following options: • Allow only stations in the list. Any station that is not in the Stations List is denied access to the network through the AP. • Block all stations in list. Only the stations that appear in the list are denied access to the network through the AP. All other stations are permitted access. Note: The filter you select is applied to the clients in the station list, regardless of whether that station list is local or on the RADIUS server. Stations List This is the local list of clients that are either permitted or denied access to the network through the AP. To add a MAC Address to the local Stations List, enter its 48‐bit MAC address into the lower text boxes, then click Add. To remove a MAC Address from the Stations List, select its 48‐bit MAC address, then click Remove. The stations in the list will either be allowed or denied access based on how you set the filter in the previous field. Note: If the MAC authentication type for the VAP is set to Local, the AP uses the Stations List to permit or deny the clients access to the network. If the MAC authentication type is set to RADIUS, the AP ignores the MAC addresses configured in this list and uses the list that is stored on the RADIUS server. The MAC authentication type is set on the VAP configuration page. D-Link Unified Access Point Administrator’s Guide November 2011 Page 86...

Page 89: Managed access point overview

Unified Access Point Administrator’s Guide Managed Access Point Overview Managed Access Point Overview The UAP can operate in two modes: Standalone Mode or Managed Mode. In Standalone Mode, the UAP acts as an individual AP in the network, and you manage it by using the Administrator Web User Interface (UI), CLI, or SNMP. In Managed Mode, the UAP is part of the D‐Link Unified Wired and Wireless System, and you manage it by using the D‐Link Unified Wireless Switch. If an AP is in Managed Mode, the Administrator Web UI, Telnet, SSH, and SNMP services are disabled. On the UAP, you can configure the IP addresses of up to four D‐Link Unified Wireless Switches that can manage it. In order to manage the AP, the switch and AP must discover each other. There are multiple ways for a switch to discover an AP. Adding the IP address of the switch to the AP while it is in Standalone Mode is one way to enable switch‐to‐AP discovery. Transitioning Between Modes Every 30 seconds, the D‐Link Unified Wireless Switch sends a keepalive message to all of the access points it manages. Each AP checks for the keepalive messages on the SSL TCP connection. As long as the AP maintains communication with the switch through the keepalive messages, it remains in Managed Mode. If the AP does not receive a message within 45 seconds of the last keepalive message, the AP assumes the switch has failed and terminates its TCP connection to the switch, and the AP enters Standalone Mode. Once the AP transitions to Standalone Mode, it continues to forward traffic without any loss. The AP uses the configuration on the VAPs configured in VLAN Forwarding mode (the standard, non‐tunneled mode). While the AP is in Standalone Mode, you can manage it by using the Web interface or the CLI (through Telnet or SSH). For any clients that are connected to the AP through tunneled VAPs, the AP sends disassociate messages and disables the tunneled VAPs. As long as the Managed AP Administrative Mode is set to Enabled, as Figure 24 on page 90 shows, the AP starts discovery procedures. If the AP establishes a connection with a wireless switch, which may or may not be the same switch it was connected to before, the switch sends the AP its configuration and the AP sends the wireless switch information about all currently associated clients. After the configuration from the switch is applied, the AP radio(s) restart. Client traffic is briefly interrupted until the radio(s) are up and the clients are re‐associated.

Only the first number in the range is configurable. The default value is 57775 (through 57784). Note: When the wireless Base IP Port number is changed on the switch, the wireless feature is automatically disabled and re‐enabled. The new value is not sent as part of the global switch configuration in the cluster configuration distribution command; every switch in the cluster must be configured independently with the new Wireless IP port number. Note: When the Wireless Base IP Port number is changed from its default value on the switch, it must also be changed on the Access Points. Pass Phrase Select the Edit option and enter a passphrase to allow the AP to authenticate itself with the wireless switch. The passphrase must be between 8 and 63 characters.

Unless specifically noted, all configuration parameters on this page apply to SNMPv1 and SNMPv2c only. Key components of any SNMP‐managed network are managed devices, SNMP agents, and a management system. The agents store data about their devices in Management Information Bases (MIBs) and return this data to the SNMP manager when requested. Managed devices can be network nodes such as APs, routers, switches, bridges, hubs, servers, or printers. The UAP can function as an SNMP managed device for seamless integration into network management systems such as HP OpenView. From the SNMP page under the Services heading, you can start or stop control of SNMP agents, configure community passwords, access MIBs, and configure SNMP Trap destinations. From the pages under the SNMPv3 heading, you can manage SNMPv3 users and their security levels and define access control to the SNMP MIBs. For information about how to configure SNMPv3 views, groups, users, and targets, see “Configuring SNMPv3” on page 111. To configure SNMP, click the SNMP tab under the Services heading and update the fields described in Table 36 on page 96 D-Link Unified Access Point Administrator’s Guide November 2011 Page 95...

Read‐only Enter a read‐only community name. The valid range is 1‐256 characters. community name The community name, as defined in SNMPv2c, acts as a simple authentication (for permitted SNMP get mechanism to restrict the machines on the network that can request data to the operations) SNMP agent. The name functions as a password, and the request is assumed to be authentic if the sender knows the password. The community name can be in any alphanumeric format.

The valid range is 1‐256 characters. Management System As with community names, this provides a level of security on SNMP settings. The SNMP agent will only accept requests from the hostname or subnet specified here. To specify a subnet, enter one or more subnetwork address ranges in the form address/mask_length where address is an IP address and mask_length is the number of mask bits. Both formats address/mask and address/ mask_length are supported. Individual hosts can be provided for this, i.e. I.P Address or Hostname. For example, if you enter a range of 192.168.1.0/24 this specifies a subnetwork with address 192.168.1.0 and a subnet mask of 255.255.255.0. The address range is used to specify the subnet of the designated NMS. Only machines with IP addresses in this range are permitted to execute get and set requests on the managed device. Given the example above, the machines with addresses from 192.168.1.1 through 192.168.1.254 can execute SNMP commands on the device. (The address identified by suffix .0 in a subnetwork range is always reserved for the subnet address, and the address identified by .255 in the range is always reserved for the broadcast address). As another example, if you enter a range of 10.10.1.128/25 machines with IP addresses from 10.10.1.129 through 10.10.1.254 can execute SNMP requests on managed devices. In this example, 10.10.1.128 is the network address and 10.10.1.255 is the broadcast address. 126 addresses would be designated. IPv6 Hostname or IPv6 Specify the IPv6 DNS hostname or subnet of the machines that can execute get and subnet of Network set requests to the managed devices.

Page 102: Configuring quality of service

Unified Access Point Administrator’s Guide Configuring Quality of Service Configuring Quality of Service Quality of Service (QoS) provides you with the ability to specify parameters on multiple queues for increased throughput and better performance of differentiated wireless traffic like Voice‐over‐IP (VoIP), other types of audio, video, and streaming media, as well as traditional IP data over the UAP. Configuring QoS on the UAP consists of setting parameters on existing queues for different types of wireless traffic, and effectively specifying minimum and maximum wait times (through Contention Windows) for transmission. The settings described here apply to data transmission behavior on the AP only, not to that of the client stations. AP Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the AP to the client station. Station Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the client station to the AP. The default values for the AP and station EDCA parameters are those suggested by the Wi‐Fi Alliance in the WMM specification. In normal use these values should not need to be changed. Changing these values will affect the QoS provided. Note: On the DWL‐6600AP and DWL‐8600AP, the QoS settings apply to both radios, but the traffic for each radio is queued independently. To set up queues for QoS, click the QoS tab under the Services heading and configure settings as described in Table 40 on page 103. D-Link Unified Access Point Administrator’s Guide November 2011 Page 102...
Page 103: Figure 31: Configuring qos settings

AP EDCA Parameters Queue Queues are defined for different types of data transmitted from AP‐to‐station: • Data 0 (Voice) — H igh priority queue, minimum delay. Time‐sensitive data such as VoIP and streaming media are automatically sent to this queue. • Data 1(Video) — H igh priority queue, minimum delay. Time‐sensitive video data is automatically sent to this queue. • Data 2 (best effort) — M edium priority queue, medium throughput and delay. Most traditional IP data is sent to this queue. • Data 3 (Background) — L owest priority queue, high throughput. Bulk data that requires maximum throughput and is not time‐sensitive is sent to this queue (FTP data, for example). AIFS The Arbitration Inter‐Frame Spacing (AIFS) specifies a wait time for data frames. (Inter‐Frame Space) The wait time is measured in slots. Valid values for AIFS are 1 through 255. D-Link Unified Access Point Administrator’s Guide November 2011 Page 103...
Page 104

The value specified for the Maximum Contention Window is the upper limit (in (Maximum Contention milliseconds) for the doubling of the random backoff value. This doubling continues Window) until either the data frame is sent or the Maximum Contention Window size is reached. Once the Maximum Contention Window size is reached, retries will continue until a maximum number of retries allowed is reached. Valid values for cwMax are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for cwMax must be higher than the value for cwMin. Max. Burst Length The Max. Burst Length is an AP EDCA parameter and only applies to traffic flowing from the AP to the client station. This value specifies (in milliseconds) the maximum burst length allowed for packet bursts on the wireless network. A packet burst is a collection of multiple frames transmitted without header information. The decreased overhead results in higher throughput and better performance. Valid values for maximum burst length are 0.0 through 999. Wi-Fi Multimedia Settings Wi‐Fi MultiMedia Wi‐Fi MultiMedia (WMM) is enabled by default. With WMM enabled, QoS prioritization and coordination of wireless medium access is on. With WMM enabled, QoS settings on the UAP control downstream traffic flowing from the AP to client station (AP EDCA parameters) and the upstream traffic flowing from the station to the AP (station EDCA parameters). Disabling WMM deactivates QoS control of station EDCA parameters on upstream traffic flowing from the station to the AP. With WMM disabled, you can still set some parameters on the downstream traffic flowing from the AP to the client station (AP EDCA parameters). To disable WMM extensions, click Disabled. To enable WMM extensions, click Enabled. D-Link Unified Access Point Administrator’s Guide November 2011 Page 104...
Page 105

Window is the upper limit (in milliseconds) of a range from which the initial random backoff wait time will be determined. The first random number generated will be a number between 0 and the number specified here. If the first random backoff wait time expires before the data frame is sent, a retry counter is incremented and the random backoff value (window) is doubled. Doubling will continue until the size of the random backoff value reaches the number defined in the Maximum Contention Window. cwMax The value specified here in the Maximum Contention Window is the upper limit (in (Maximum Contention milliseconds) for the doubling of the random backoff value. This doubling continues Window) until either the data frame is sent or the Maximum Contention Window size is reached. Once the Maximum Contention Window size is reached, retries will continue until a maximum number of retries allowed is reached. TXOP Limit The TXOP Limit is a station EDCA parameter and only applies to traffic flowing from the client station to the AP. The Transmission Opportunity (TXOP) is an interval of time, in milliseconds, when a WME client station has the right to initiate transmissions onto the wireless medium (WM) towards the Unified Access Point. The TXOP Limit maximum value is 65535. Other QoS Settings No Acknowledgement Select On to specify that the AP should not acknowledge frames with QosNoAck as the service class value. APSD Select On to enable Automatic Power Save Delivery (APSD), which is a power management method. APSD is recommended if VoIP phones access the network through the AP. Note: After you configure the QoS settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low.

Unified Access Point Administrator’s Guide Enabling the Time Settings (NTP) Enabling the Time Settings (NTP) Use the Time Settings page to specify the Network Time Protocol (NTP) server to use to provide time and date information to the AP or to configure the time and date information manually. NTP is an Internet standard protocol that synchronizes computer clock times on your network. NTP servers transmit Coordinated Universal Time (UTC, also known as Greenwich Mean Time) to their client systems. NTP sends periodic time requests to servers, using the returned time stamp to adjust its clock. The timestamp is used to indicate the date and time of each event in log messages. See http://www.ntp.org for more information about NTP. To set the system time either manually or by specifying the address of the NTP server for the AP to use, click the Services > Time Settings (NTP) tab and update the fields as described in Table 42 on page 110.

You can create MIB views to control the OID range that SNMPv3 users can access. A MIB view called "all" is created by default in the system. This view contains all management objects supported by the system. Note: If you create an excluded view subtree, create a corresponding included entry with the same view name to allow subtrees outside of the excluded subtree to be included. For example, to create a view that excludes the subtree 1.3.6.1.4, create an excluded entry with the OID 1.3.6.1.4. Then, create an included entry with OID .1 with the same view name.

Page 112: Table 43: Snmpv3 views

Unified Access Point Administrator’s Guide Configuring SNMPv3 Views Table 43 describes the fields you can configure on the SNMPv3 Views page. Table 43: SNMPv3 Views Field Description View Name Enter a name to identify the MIB view. View names can contain up to 32 alphanumeric characters. Type Specifies whether to include or exclude the view subtree or family of subtrees from the MIB view. Enter an OID string for the subtree to include or exclude from the view. For example, the system subtree is specified by the OID string .1.3.6.1.2.1.1. Mask The OID mask is 47 characters in length. The format of the OID mask is xx.xx.xx (.)... or xx:xx:xx.. (:) and is 16 octets in length. Each octet is 2 hexadecimal characters separated by either . (period) or : (colon). Only hex characters are accepted in this field. For example, OID mask FA.80 is 11111010.10000000. A family mask is used to define a family of view subtrees. The family mask indicates which sub‐identifiers of the associated family OID string are significant to the family's definition. A family of view subtrees allows control access to one row in a table, in a more efficient manner. SNMPv3 Views This field shows the MIB views on the UAP.

Unified Access Point Administrator’s Guide Configuring SNMPv3 Groups Configuring SNMPv3 Groups SNMPv3 groups allow you to combine users into groups of different authorization and access privileges. By default, the UAP has two groups: • RO — A read‐only group using authentication and data encryption. Users in this group use an MD5 key/ password for authentication and a DES key/password for encryption. Both the MD5 and DES key/ passwords must be defined. By default, users of this group will have read only access to the default all MIB view, which can be modified by the user. • RW — A read/write group using authentication and data encryption. Users in this group use an MD5 key/ password for authentication and a DES key/password for encryption. Both the MD5 and DES key/ passwords must be defined. By default, users of this group will have read and write access to the default all MIB view, which can be modified by the user. RW and RO groups are defined by default. Note: The UAP supports maximum of eight groups. To define additional groups, navigate to the SNMPv3 Groups page and configure the settings that Table 44 on page 114 describes.

Unified Access Point Administrator’s Guide Performing AP Maintenance Performing AP Maintenance From the Maintenance page, you can reset the AP to its factory default settings or reboot the AP. Figure 38: Maintenance Resetting the Factory Default Configuration If you are experiencing problems with the UAP and have tried all other troubleshooting measures, click Reset. This restores factory defaults and clears all settings, including settings such as a new password or wireless settings. You can also use the reset button on the back panel to reset the system to the default configuration. Rebooting the Access Point For maintenance purposes or as a troubleshooting measure, you can reboot the UAP. To reboot the AP, click the Reboot button on the Configuration page. Upgrading the Firmware As new versions of the UAP firmware become available, you can upgrade the firmware on your devices to take advantage of new features and enhancements. The AP uses a TFTP client for firmware upgrades. You can also use HTTP to perform firmware upgrades. After you upload new firmware and the system reboots, the newly added firmware becomes the primary image. If the upgrade fails, the original firmware remains as the primary image. Note: When you upgrade the firmware, the access point retains the existing configuration information. Use the following steps to upgrade the firmware on an access point by using TFTP: 1. Select TFTP for Upload Method. 2. Enter a name (1 to 63 characters) for the image file in the Image Filename field, including the path to the directory that contains the image to upload.

For example, to upload the ap_upgrade.tar image located in the /share/builds/ap directory, enter /share/ builds/ap/ap_upgrade.tar in the Image Filename field. The firmware upgrade file supplied must be a tar file. Do not attempt to use bin files or files of other formats for the upgrade; these types of files will not work. 3. Enter the IP address of the TFTP server. 4. Click Upgrade. Upon clicking Upgrade for the firmware upgrade, a popup confirmation window is displayed that describes the upgrade process. 5. Click OK to confirm the upgrade and start the process. Note: The firmware upgrade process begins once you click Upgrade and then OK in the popup confirmation window. The upgrade process may take several minutes during which time the access point will be unavailable. Do not power down the access point while the upgrade is in process. When the upgrade is complete, the access point restarts. The AP resumes normal operation with the same configuration settings it had before the upgrade. 6. To verify that the firmware upgrade completed successfully, check the firmware version shown on the Upgrade page (or the Basic Settings page). If the upgrade was successful, the updated version name or number is indicated. Use the following steps to upgrade the firmware on an access point by using HTTP: 1. Select HTTP for Upload Method. 2. If you know the path to the new firmware image file, enter it in the Image Filename field. Otherwise, click the Browse button and locate the firmware image file. The firmware upgrade file supplied must be a tar file. Do not attempt to use bin files or files of other formats for the upgrade; these types of files will not work. 3.

5. To verify that the firmware upgrade completed successfully, check the firmware version shown on the Upgrade page (or the Basic Settings page). If the upgrade was successful, the updated version name or number is indicated. Packet Capture Configuration and Settings Wireless packet capture operates in two modes: • Capture file mode • Remote capture mode For capture file mode, captured packets are stored in a file on the Access Point. The AP can transfer the file to a TFTP server. The file is formatted in pcap format and can be examined using tools such as Wireshark and OmniPeek. For remote capture mode, the captured packets are redirected in real time to an external PC running the Wireshark® tool. The AP can capture the following types of packets: • 802.11 packets received and transmitted on radio interfaces. Packets captured on radio interfaces include the 802.11 header. • 802.3 packets received and transmitted on the Ethernet interface. • 802.3 packets received and transmitted on the internal logical interfaces such as VAPs and WDS interfaces. From the Packet Capture Configuration and Settings page, you can: • View the current packet capture status. • Configure packet capture parameters. • Configure packet file capture. • Configure a remote capture port. • Download a packet capture file.

Page 124: Packet capture status

Description Current Capture Status Shows whether packet capture is running or stopped. Packet Capture Time Shows elapsed capture time. Packet Capture File Size Shows the current capture file size. Packet Capture Parameter Configuration Packet Capture Configuration allows you to configure parameters that affect how packet capture functions on the radio interfaces. Table 48 describes the fields to configure the packet capture. Table 48: Packet Capture Configuration Field Description Capture Beacons Enable to capture the 802.11 beacons detected or transmitted by the radio. Promiscuous Capture Enable to place the radio in promiscuous mode when the capture is active. In promiscuous mode the radio receives all traffic on the channel, including traffic that is not destined to this AP. While the radio is operating in promiscuous mode, it continues serving associated clients. Packets not destined to the AP are not forwarded. As soon as the capture is completed, the radio reverts to non‐promiscuous mode operation. Client Filter Enable Enable to use the WLAN client filter to capture only frames that are transmitted to, or received from a WLAN client with a specified MAC address. Client Filter MAC Address Specify a MAC address for WLAN client filtering. Note: The MAC filter is active only when capture is performed on an 802.11 interface. Note: Changes to packet capture configuration parameters take affect after packet capture is restarted. Modifying the parameters while the packet capture is running doesn't affect the current packet capture session. In order to begin using new parameter values, an existing packet capture session must be stopped and re‐started. D-Link Unified Access Point Administrator’s Guide November 2011 Page 124...
Page 125: Packet file capture

Table 49: Packet File Capture Field Description Capture Interface Select an AP Capture Interface name from the drop‐down menu. AP capture interface names are eligible for packet capture are: • brtrunk ‐ Linux bridge interface in the AP • eth0 ‐ 802.3 traffic on the Ethernet port. • wlan0 ‐ VAP0 traffic on radio 1. • wlan1 ‐ VAP0 traffic on radio 2. • radio1 ‐ 802.11 traffic on radio 1. • radio2 ‐ 802.11 traffic on radio 2. Note: The DWL‐3600AP has only one radio. The available options on the DWL‐3600AP do not include wlan0 or radio1. Capture Duration Specify the time duration in seconds for the capture (range 10 to 3600). Max Capture File Size Specify the maximum allowed size for the capture file in KB (range 64 to 4096). Remote Packet Capture Remote Packet Capture allows you to specify a remote port as the destination for packet captures. This feature works in conjunction with the Wireshark network analyzer tool for Windows. A packet capture server runs on the AP and sends the captured packets via a TCP connection to the Wireshark tool. A Windows PC running the Wireshark tool allows you to display, log, and analyze captured traffic. When the remote capture mode is in use, the AP doesn't store any captured data locally in its file system. Your can trace up to five interfaces on the AP at the same time. However, you must start a separate Wireshark session for each interface. You can configure the IP port number used for connecting Wireshark to the AP. The default port number is 2002. The system uses 5 consecutive port numbers starting with the configured port for the packet capture sessions. If a firewall is installed between the Wireshark PC and the AP, these ports must be allowed to pass through the firewall. The firewall must also be configured to allow the Wireshark PC to initiate TCP connection to the AP. D-Link Unified Access Point Administrator’s Guide November 2011 Page 125...
Page 126

When you are capturing traffic on the radio interface, you can disable beacon capture, but other 802.11 control frames are still sent to Wireshark. You can set up a display filter to show only: • Data frames in the trace • Traffic on specific BSSIDs • Traffic between two clients Some examples of useful display filters are: • Exclude beacons and ACK/RTS/CTS frames: !(wlan.fc.type_subtype == 8 || wlan.fc.type == 1) • Data frames only: wlan.fc.type == 2 • Traffic on a specific BSSID: wlan.bssid == 00:02:bc:00:17:d0 • All traffic to and from a specific client: wlan.addr == 00:00:e8:4e:5f:8e In remote capture mode, traffic is sent to the PC running Wireshark via one of the network interfaces. Depending on where the Wireshark tool is located the traffic can be sent on an Ethernet interface or one of the radios. In order to avoid a traffic flood caused by tracing the trace packets, the AP automatically installs a capture filter to filter out all packets destined to the Wireshark application. For example if the Wireshark IP port is configured to be 58000 then the following capture filter is automatically installed on the AP: not portrange 58000‐58004. Enabling the packet capture feature impacts performance of the AP and can create a security issue (unauthorized clients may be able to connect to the AP and trace user data). The AP performance is negatively impacted even if there is no active Wireshark session with the AP. The performance is negatively impacted to a greater extent when packet capture is in progress. Due to performance and security issues, the packet capture mode is not saved in NVRAM on the AP; if the AP resets, the capture mode is disabled and the you must re‐enable it in order to resume capturing traffic. Packet capture parameters (other than mode) are saved in NVRAM. D-Link Unified Access Point Administrator’s Guide November 2011 Page 126...

Packet Capture File Download Packet Capture File Download allows you to download the capture file by TFTP to a configured TFTP server or by HTTP(S) to a PC. The captured packets are stored in file /tmp/apcapture.pcap on the AP. A capture is automatically stopped when the capture file download command is triggered. Because the capture file is located in the RAM file system, it disappears if the AP is reset. Table 51 describes the fields to configure the packet capture status.

Page 128: Section 8: configuring client quality of service

Unified Access Point Administrator’s Guide Configuring Client Quality of Service Section 8: Configuring Client Quality of Service This section describes how to configure QoS settings that affect traffic from the wireless clients to the AP. By using the UAP Client QoS features, you can limit bandwidth and apply ACLs and DiffServ policies to the wireless interface. If a VAP uses WPA Enterprise security to authenticate clients, you can configure the RADIUS server to provide per‐client QoS information. This section describes the following features: • “Configuring VAP QoS Parameters” • “Managing Client QoS ACLs” • “Creating a DiffServ Class Map” • “Creating a DiffServ Policy Map” • “Configuring RADIUS‐Assigned Client QoS Parameters” Note: The web‐based UI images in this section show the DWL‐8600AP administration pages. Pages for the DWL‐3600AP will not display information for Radio 2 because it has only one radio. Configuring VAP QoS Parameters The client QoS features on the UAP provide additional control over certain QoS aspects of wireless clients that connect to the network, such as the amount of bandwidth an individual client is allowed to send and receive. To control general categories of traffic, such as HTTP traffic or traffic from a specific subnet, you can configure ACLs and assign them to one or more VAPs. In addition to controlling general traffic categories, Client QoS allows you to configure per‐client conditioning of various micro‐flows through Differentiated Services (DiffServ). DiffServ policies are a useful tool for establishing general micro‐flow definition and treatment characteristics that can be applied to each wireless client, both inbound and outbound, when it is authenticated on the network. From the VAP QoS Parameters page, you can enable the Client QoS feature, specify client bandwidth limits, and select the ACLs and DiffServ policies to use as default values for clients associated with the VAP when the client does not have their own attributes defined by a RADIUS server. To configure the Client QoS administrative mode and to configure the QoS settings for a VAP, click the VAP QoS Parameters tab.

The UAP supports up to 50 IPv4, IPv6, and MAC ACLs. IPv4 and IPv6 ACLs IP ACLs classify traffic for Layers 3 and 4. Each ACL is a set of up to 10 rules applied to traffic sent from a wireless client or to be received by a wireless client. Each rule specifies whether the contents of a given field should be used to permit or deny access to the network. Rules can be based on various criteria and may apply to one ore more fields within a packet, such as the source or destination IP address, the source or destination L4 port, or the protocol carried in the packet. MAC ACLs MAC ACLs are Layer 2 ACLs. You can configure the rules to inspect fields of a frame such as the source or destination MAC address, the VLAN ID, or the Class of Service 802.1p priority. When a frame enters or exits the AP port (depending on whether the ACL is applied in the up or down direction), the AP inspects the frame and checks the ACL rules against the content of the frame. If any of the rules match the content, a permit or deny action is taken on the frame. ACL Configuration Process Configure ACLs and rules on the Client QoS ACL page (steps 1 – 5 ), and then apply the rules to a specified VAP on the AP QoS Parameters page (step 6). Use the following general steps to configure ACLs: 1. Specify a name for the ACL. 2. Select the type of ACL to add. 3. Add the ACL 4. Add new rules to the ACL. 5. Configure the match criteria for the rules. 6. Apply the ACL to one or more VAPs. For an example of how to configure an ACL, see “ACL Configuration” on page 174 To configure an ACL, click the Client QoS ACL tab.

Page 138: Creating a diffserv class map

Unified Access Point Administrator’s Guide Creating a DiffServ Class Map Creating a DiffServ Class Map The Client QoS feature contains Differentiated Services (DiffServ) support that allows traffic to be classified into streams and given certain QoS treatment in accordance with defined per‐hop behaviors. Standard IP‐based networks are designed to provide best effort data delivery service. Best effort service implies that the network delivers the data in a timely fashion, although there is no guarantee that it will. During times of congestion, packets may be delayed, sent sporadically, or dropped. For typical Internet applications, such as e‐mail and file transfer, a slight degradation in service is acceptable and in many cases unnoticeable. However, on applications with strict timing requirements, such as voice or multimedia, any degradation of service has undesirable effects. By classifying the traffic and creating policies that define how to handle these traffic classes, you can make sure that time‐sensitive traffic is given precedence over other traffic. The UAP supports up to 50 Class Maps. Defining DiffServ To use DiffServ for Client QoS, use the Class Map and Policy Map pages to define the following categories and their criteria: • Class: create classes and define class criteria • Policy: create policies, associate classes with policies, and define policy statements Once you define the class and associate it with a policy, apply the policy to a specified VAP on the VAP QoS Parameters page. Packets are classified and processed based on defined criteria. The classification criteria is defined by a class. The processing is defined by a policy's attributes. Policy attributes may be defined on a per‐class instance basis, and it is these attributes that are applied when a match occurs. A policy can contain multiple classes. When the policy is active, the actions taken depend on which class matches the packet. Packet processing begins by testing the class match criteria for a packet. A policy is applied to a packet when a class match within that policy is found. DiffServ is supported for IPv4 and IPv6 packets. Use the Class Map page to add a new Diffserv class name, or to rename or delete an existing class, and define the criteria to associate with the DiffServ class. To configure a DiffServ Class Map, click the Class Map tab. Note: The Class Map page displays the Match Criteria Configuration fields only if a Class Map has been created. To create a Class Map, enter a name in the Class Map Name field and click Add Class Map. D-Link Unified Access Point Administrator’s Guide November 2011 Page 138...

To match a protocol that is not listed by name, enter the protocol ID. The protocol ID is a standard value assigned by the IANA. The range is a number from 0 – 2 55. IPv4 Class Maps Source IP Address Select this field to require a packet's source IP address to match the address listed here. Enter an IP address in the appropriate field to apply this criteria. Source IP Mask Enter the source IP address mask. The mask for DiffServ is a network‐style bit mask in IP dotted decimal format indicating which part(s) of the destination IP Address to use for matching against packet content. A DiffServ mask of 255.255.255.255 indicates that all bits are important, and a mask of 0.0.0.0 indicates that no bits are important. The opposite is true with an ACL wild card mask. For example, to match the criteria to a single host address, use a DiffServ mask of 255.255.255.255. To match the criteria to a 24‐ bit subnet (for example 192.168.10.0/24), use a mask of 255.255.255.0. Destination IP Address Select this field to require a packet's destination IP address to match the address listed here. Enter an IP address in the appropriate field to apply this criteria. Destination IP Mask Enter the destination IP address mask. The mask for DiffServ is a network‐style bit mask in IP dotted decimal format indicating which part(s) of the destination IP Address to use for matching against packet content. A DiffServ mask of 255.255.255.255 indicates that all bits are important, and a mask of 0.0.0.0 indicates that no bits are important. The opposite is true with an ACL wild card mask.

Page 144: Creating a diffserv policy map

Unified Access Point Administrator’s Guide Creating a DiffServ Policy Map Creating a DiffServ Policy Map Use the Policy Map page to create DiffServ policies and to associate a collection of classes with one or more policy statements. The UAP supports up to 50 Policy Maps. Packets are classified and processed based on defined criteria. The classification criteria is defined by a class on the Class Map page. The processing is defined by a policy's attributes on the Policy Map page. Policy attributes may be defined on a per‐class instance basis, and it is these attributes that are applied when a match occurs. A Policy Map can contain up to 10 Class Maps. When the policy is active, the actions taken depend on which class matches the packet. Packet processing begins by testing the class match criteria for a packet. A policy is applied to a packet when a class match within that policy is found. To create a DiffServ policy, click the Policy Map tab.

Station The Station menu contains the MAC address of each client currently associated with the AP. To view the QoS settings applied to a client, select its MAC address from the list. Global QoS Mode Shows the current Client QoS Global Admin Mode on the AP. Client QoS Mode Shows whether the QOS mode for the selected client is enabled or disabled. Note: For the Qos Mode to be enabled on a client, it must be globally enabled on the AP and enabled on the VAP the client is associated with. Use the VAP QoS Parameters page to enable the QoS Global Admin mode and the per‐VAP QoS Mode. Bandwidth Limit Up Shows the maximum allowed transmission rate from the client to the AP in bits per second (bps). The valid range is 0 – 4 294967295 bps. Bandwidth Limit Down Shows the maximum allowed transmission rate from the AP to the client in bits per second (bps). The valid range is 0 – 4 294967295 bps. ACL Type Up Shows the type of ACL that is applied to traffic in the inbound (client‐to‐AP) direction, which can be one of the following: • IPv4: The ACL examines IPv4 packets for matches to ACL rules. • IPv6: The ACL examines IPv6 packets for matches to ACL rules. • MAC: The ACL examines layer 2 frames for matches to ACL rules.

After switching the packet or frame to the outbound interface, the ACL's rules are checked for a match. The packet or frame is transmitted if it is permitted and discarded if it is denied. DiffServ Policy Up Shows the name of the DiffServ policy applied to traffic sent to the AP in the inbound (client‐to‐AP) direction. DiffServ Policy Down Shows the name of the DiffServ policy applied to traffic from the AP in the outbound (AP‐to‐client) direction. Configuring RADIUS‐Assigned Client QoS Parameters If a VAP is configured to use WPA Enterprise security, you can include client QoS information in the client database on the RADIUS server. When a client successfully authenticates, the RADIUS server can include bandwidth limits and identify the ACLs and DiffServ policies to apply to the specific wireless client. ACLs and DiffServ policies referenced in the RADIUS client database must match the names of the ACLs and DiffServ policies configured on the AP to be successfully applied to the wireless clients. Table 57 describes the QoS attributes that can be included in the client's RADIUS server entry. If a wireless client successfully authenticates using WPA Enterprise, each QoS RADIUS attribute that exists for the client is sent to the AP for processing. The attributes are optional and do not need to be present in the client entry. If the attribute is not present, the Client QoS setting on the AP is used.

Page 149: Section 9: clustering multiple aps

Unified Access Point Administrator’s Guide Clustering Multiple APs Section 9: Clustering Multiple APs The UAP supports AP clusters. A cluster provides a single point of administration and lets you view, deploy, configure, and secure the wireless network as a single entity rather than a series of separate wireless devices. Managing Access Points in the Cluster The AP cluster is a dynamic, configuration‐aware group of APs in the same subnet of a network. Each cluster can have up to 16 members. Only one cluster per wireless network is supported; however, a network subnet can have multiple clusters. Clusters can share various configuration information, such as VAP settings and QoS queue parameters. A cluster can be formed between two APs if the following conditions are met: • The APs use the same radio mode (for example, radio 1 uses 802.11g) • The APs are connected on the same bridged segment. • The APs joining the cluster have the same Cluster Name. • Clustering mode is enabled on both APs. Note: For two APs to be in the same cluster, they do not need to have the same number of radios; however, the supported capabilities of the radios should be same. Note: The web‐based UI images in this section show the DWL‐8600AP administration pages. Pages for the DWL‐3600AP will not display information for Radio 2 because it has only one radio. Clustering Single and Dual Radio APs Clustering of single‐ and dual‐radios is not supported. A cluster can contain a mix if DWL‐6600AP and DWL‐8600AP access points, but this cluster should not contain any DWL‐3600APs. Viewing and Configuring Cluster Members The Access Points page allows you to start or stop clustering on an AP, view the cluster members, and configure the location and cluster name for a cluster member. From the Access Points page, you can also click the IP address of each cluster member to navigate to configuration settings and data on an access point in the cluster. To view information about cluster members and to configure the location and cluster of an individual member, click the Access Points tab.

The address shown here is the MAC address for the bridge ( ). This is the address by which the AP is known externally to other networks. IP Address Specifies the IP address for the access point. Each IP address is a link to the Administration Web pages for that access point. You can use the links to navigate to the Administration Web pages for a specific access point. This is useful for viewing data on a specific access point to make sure a cluster member is picking up cluster configuration changes, to configure advanced settings on a particular access point, or to switch a standalone access point to cluster mode. The following table describes the cluster information to configure for an individual member. The clustering options are read‐only when clustering is enabled. To configure the clustering options, you must stop clustering. Table 59: Clustering Options Field Description Location Enter a description of where the access point is physically located. Cluster Name Enter the name of the cluster for the AP to join. The cluster name is not sent to other APs in the cluster. You must configure the same cluster name on each AP that is a member of the cluster. The cluster name must be unique for each cluster you configure on the network. Clustering IP Version Specify the IP version that the APs in the cluster use to communicate with each other. Removing an Access Point from the Cluster To remove an access point from the cluster, do the following. 1. Go to the Administration Web pages for the clustered access point. The Administration Web pages for the standalone access point are displayed. 2. Click the Cluster > Access Points link in the Administration pages. 3. Click Stop Clustering. The change will be reflected under Status for that access point; the access point will now show as stand‐alone (instead of cluster).

Page 152: Adding an access point to a cluster

Unified Access Point Administrator’s Guide Managing Access Points in the Cluster Adding an Access Point to a Cluster To add an access point that is currently in standalone mode back into a cluster, do the following. 1. Go to the Administration Web pages for the standalone access point. 2. Click the Cluster > Access Points link in the Administration pages for the stand‐alone access point. The Access Points page for a standalone access point indicates that the current mode is standalone. 3. Type the name or location of the AP in the Location field to identify the AP within the cluster. 4. Type the name of the cluster for the AP to join in the Cluster Name field. 5. Click Start Clustering. The access point is now a cluster member. Its Status (Mode) on the Cluster > Access Points page now indicates Cluster instead of Not Clustered. Navigating to Configuration Information for a Specific AP In general, the UAP is designed for central management of clustered access points. For access points in a cluster, all access points in the cluster reflect the same configuration. In this case, it does not matter which access point you actually connect to for administration. There may be situations, however, when you want to view or manage information on a particular access point. For example, you might want to check status information such as client associations or events for an access point. In this case, you can navigate to the Administration Web interface for individual access points by clicking the IP address links on the Access Points page. All clustered access points are shown on the Cluster > Access Points page. To navigate to clustered access points, you can simply click on the IP address for a specific cluster member shown in the list. Navigating to an AP by Using its IP Address in a URL You can also link to the Administration Web pages of a specific access point, by entering the IP address for that access point as a URL directly into a Web browser address bar in the following form: http://IPAddressOfAccessPoint where IPAddressOfAccessPoint is the address of the particular access point you want to monitor or configure.

Page 153: Managing cluster sessions

Unified Access Point Administrator’s Guide Managing Cluster Sessions Managing Cluster Sessions The Sessions page shows information about client stations associated with access points in the cluster. Each client is identified by its MAC address, along with the AP (location) to which it is currently connected. To view a particular statistic for client sessions, select an item from the Display drop‐down list and click Go. You can view information about idle time, data rate, signal strength and so on; all of which are described in detail in the table below. A session in this context is the period of time in which a user on a client device (station) with a unique MAC address maintains a connection with the wireless network. The session begins when the client logs on to the network, and the session ends when the client either logs off intentionally or loses the connection for some other reason. Note: A session is not the same as an association, which describes a client connection to a particular access point. A client network connection can shift from one clustered AP to another within the context of the same session. A client station can roam between APs and maintain the session. To manage sessions associated with the cluster, click Cluster > Sessions. Figure 47: Session Management Details about the session information shown is described in the following table. Table 60: Session Management Field Description AP Location Indicates the location of the access point. This is derived from the location description specified on the Basic Settings page. User MAC Indicates the MAC address of the wireless client device. A MAC address is a hardware address that uniquely identifies each node of a network. Idle Indicates the amount of time this station has remained inactive. A station is considered to be idle when it is not receiving or transmitting data.

Page 154: Sorting session information

This value should fall within the range of the advertised rate set for the mode in use on the access point. For example, 6 to 54 Mbps for 802.11a. Signal Indicates the strength of the radio frequency (RF) signal the client receives from the access point. The measure used for this is a value known as Received Signal Strength Indication (RSSI), and will be a value between 0 and 100. RSSI is determined by a mechanism implemented on the network interface card (NIC) of the client station. Rx Total Indicates number of total packets received by the client during the current session. Tx Total Indicates number of total packets transmitted to the client during this session. Error Rate Indicates the percentage of time frames are dropped during transmission on this access point. Sorting Session Information To sort the information shown in the tables by a particular indicator, click the column label by which you want to order things. For example, if you want to see the table rows ordered by signal strength, click the Signal column label. The entries will be sorted by signal strength. Configuring and Viewing Channel Management Settings When Channel Management is enabled, the UAP automatically assigns radio channels used by clustered access points. The automatic channel assignment reduces mutual interference (or interference with other access points outside of its cluster) and maximizes Wi‐Fi bandwidth to help maintain the efficiency of communication over the wireless network. You must start channel management to get automatic channel assignments; it is disabled by default on a new At a specified interval, the Channel Manager maps APs to channel use and measures interference levels in the cluster. If significant channel interference is detected, the Channel Manager automatically re‐assigns some or all of the APs to new channels per an efficiency algorithm (or automated channel plan). If the Channel Manager determines that a change is necessary, that information is sent to all members of the cluster and a syslog message is generated indicating the sender AP, new and old channel assignments. The Channel Management page shows previous, current, and planned channel assignments for clustered access points. By default, automatic channel assignment is disabled. You can start channel management to optimize channel usage across the cluster on a scheduled interval. To configure and view the channel assignments for the cluster members, click the Channel Management tab. D-Link Unified Access Point Administrator’s Guide November 2011 Page 154...

By using the Advanced settings on the page, you can modify the interference reduction potential that triggers channel re‐assignment, change the schedule for automatic updates, and re‐configure the channel set used for assignments. Stopping/Starting Automatic Channel Assignment By default, automatic channel assignment is disabled (off). Note: Channel Management overrides the default cluster behavior, which is to synchronize radio channels of all APs across a cluster. When Channel Management is enabled, the radio Channel is not synced across the cluster to other APs. • Click Start to resume automatic channel assignment. When automatic channel assignment is enabled, the Channel Manager periodically maps radio channels used by clustered access points and, if necessary, re‐assigns channels on clustered APs to reduce interference (with cluster members or other APs outside the cluster). • Click Stop to stop automatic channel assignment. (No channel usage maps or channel re‐assignments will be made. Only manual updates will affect the channel assignment.) D-Link Unified Access Point Administrator’s Guide November 2011 Page 155...

Field Description IP Address Specifies the IP Address for the access point. Radio Identifies the MAC address of the radio. Band Indicates the band on which the access point is broadcasting. Current Indicates the radio Channel on which this access point is currently broadcasting. Status Shows whether the radio is up (on) or down (off). Locked Click Locked to force the access point to remain on the current channel. When Locked is selected (enabled) for an access point, automated channel management plans will not re‐assign the AP to a different channel as a part of the optimization strategy. Instead, APs with locked channels will be factored in as requirements for the plan. If you click Apply, you will see that locked APs show the same channel for the Current Channel and Proposed Channel fields. Locked APs will keep their current channels. Viewing the Last Proposed Set of Changes The Proposed Channel Assignments shows the last channel plan. The plan lists all access points in the cluster by IP Address, and shows the current and proposed channels for each AP. Locked channels will not be re‐ assigned and the optimization of channel distribution among APs will take into account the fact that locked APs must remain on their current channels. APs that are not locked may be assigned to different channels than they were previously using, depending on the results of the plan. Table 62: Last Proposed Changes Field Description IP Address Specifies the IP Address for the access point. Radio Indicates the radio channel on which this access point is currently broadcasting. Proposed Channel Indicates the radio channel to which this access point would be re‐assigned if the Channel Plan is executed.

Management as provided (without updating Advanced Settings), channels are automatically fine‐tuned once every hour if interference can be reduced by 25 percent or more. Channels will be re‐assigned even if the network is busy. The appropriate channel sets will be used (b/g for APs using IEEE 802.11b/g and a for APs using IEEE 802.11a). The default settings are designed to satisfy most scenarios where you would need to implement channel management. Use Advanced Settings to modify the interference reduction potential that triggers channel re‐assignment, change the schedule for automatic updates, and re‐configure the channel set used for assignments. If there are no fields showing in the Advanced section, click the toggle button to display the settings that modify timing and details of the channel planning algorithm.

Page 158: Viewing wireless neighborhood information

Unified Access Point Administrator’s Guide Viewing Wireless Neighborhood Information Viewing Wireless Neighborhood Information The Wireless Neighborhood shows up to 20 access points per radio within range of every member of the cluster, shows which access points are within range of which cluster members, and distinguishes between cluster members and non‐members. Note: The Wireless Neighborhood page shows up to 20 access points per radio. To see all the access points detected on a given cluster access point, navigate to that cluster member's web interface and go to the Status > Neighboring Access Points page. For each neighbor access point, the Wireless Neighborhood view shows identifying information (SSID or Network Name, IP Address, MAC address) along with radio statistics (signal strength, channel, beacon interval). You can click on an AP to get additional statistics about the APs in radio range of the currently selected AP. The Wireless Neighborhood view can help you: • Detect and locate unexpected (or rogue) access points in a wireless domain so that you can take action to limit associated risks • Verify coverage expectations. By assessing which APs are visible at what signal strength from other APs, you can verify that the deployment meets your planning goals. • Detect faults. Unexpected changes in the coverage pattern are evident at a glance in the color coded table.

Unified Access Point Administrator’s Guide Configuring Client QoS Clustering APs by Using SNMP Cluster configuration by using SNMP is not supported. Configuring Client QoS This example shows how to enable client QoS, configure an ACL and a DiffServ policy on the AP, and to apply the ACL and the Policy to traffic transmitted from clients associated with VAP 2 and received by the AP. The IPv4 ACL is named acl1 and contains two rules. The first rule allows HTTP traffic from the 192.168.1.0 subnet. The second rule allows all IP traffic from the management station (192.168.1.23). All other traffic is denied due to the implicit deny all rule at the end of the ACL. The ACL is applied to the inbound interface on the AP so that packets are checked when the AP receives traffic from associated clients. The DiffServ policy in this example shows how to establish default DiffServ behavior for clients associating with the VAP that do not obtain a DiffServ policy name through the RADIUS server. Voice traffic (UDP packets) received from clients in the 192.168.1.0 subnet that has the VoIP server as its destination address (192.168.2.200), is marked with the IP DSCP value for expedited forwarding so that it takes priority over other traffic. Configuring QoS by Using the Web Interface ACL Configuration 1. Log onto the AP and navigate to the Client QoS > Client QoS ACL page. 2. Enter acl1in the ACL Name field, and click Add ACL. The screen refreshes, and additional fields appear. 3. From the Action menu, select Permit. 4. Clear the Match Every option. 5.
