Page 37: Chapter 3: Network Configuration
Chapter 3: Network Configuration Wireless networks support a stand-alone configuration as well as an integrated configuration with 10/100 Mbps Ethernet LANs. The 2.4 GHz Wireless Access Point also provides repeater and bridging services. Access points can be deployed to support wireless clients and connect wired LANs in the following configurations: •...
Page 38: Network Topologies
Network Configuration Network Topologies Ad Hoc Wireless LAN (no Access Point) An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel.
Page 39: Infrastructure Wireless Lan
Network Topologies Infrastructure Wireless LAN The access point also provides access to a wired LAN for wireless workstations. An integrated wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN.
Page 40: Infrastructure Wireless Lan For Roaming Wireless Pcs
Network Configuration Infrastructure Wireless LAN for Roaming Wireless PCs The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point.
Page 41: Infrastructure Wireless Bridge
Network Topologies Infrastructure Wireless Bridge The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge connections between BSS areas (access points). The access point uses WDS to forward traffic on links between units. The access point supports WDS bridge links on the 2.4 GHz (802.11b/g) band and can be used with various external antennas to offer flexible deployment options.
Page 42: Infrastructure Wireless Repeater
Network Configuration Infrastructure Wireless Repeater The access point can also operate in a bridge “repeater” mode to extend the range of links to wireless clients. The access point uses WDS to forward traffic between the repeater bridge and the root bridge. The access point supports up to six WDS repeater links.
Page 43: Chapter 4: Initial Configuration
Chapter 4: Initial Configuration The 2.4 GHz Wireless Access Point offers a variety of management options, including a web-based interface, a direct connection to the console port, Telnet, Secure Shell (SSH), or using SNMP software. The initial configuration steps can be made through the web browser interface or CLI.
Page 44: Initial Configuration Steps
Initial Configuration For a description of how to use the CLI, see “Using the Command Line Interface” on page 6-1. For a list of all the CLI commands and detailed information on using the CLI, refer to “Command Groups” on page 6-6. Initial Configuration Steps Logging In –...
Page 45: Logging In
Logging In Setting the Country Code – Units sold in the United States are configured by default to use only radio channels 1-11 in 802.11b or 802.11g mode as defined by FCC regulations. Units sold in other countries are configured by default without a country code (i.e., 99).
Page 46 Initial Configuration The home page displays the Main Menu.
Page 47: Chapter 5: System Configuration
Chapter 5: System Configuration Before continuing with advanced configuration, first complete the initial configuration steps described in Chapter 4 to set up an IP address for the access point. The access point can be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape 6.2 or above).

However, modifying this parameter can help you to more easily distinguish different devices in your network.
Page 50 System Configuration CLI Commands for System Identification – Enter the global configuration mode, and use the system name command to specify a new system name. Then return to the Exec mode, and use the show system command to display the changes to the system identification settings.
Page 51: Tcp / Ip Settings
Advanced Configuration TCP / IP Settings Configuring the access point with an IP address expands your ability to manage the access point. A number of access point features depend on IP addressing to operate. Note: You can use the web browser interface to access IP addressing only if the access point already has an IP address that is reachable through your network.
Page 52 System Configuration • Subnet Mask: The mask that identifies the host address bits used for routing to specific subnets. • Default Gateway: The default gateway is the IP address of the router for the access point, which is used if the requested destination address is not on the local subnet. If you have management stations, DNS, RADIUS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided.
Page 53: Radius
Advanced Configuration RADIUS Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network. A primary RADIUS server must be specified for the access point to implement IEEE 802.1X network access control and Wi-Fi Protected Access (WPA) wireless security.
Page 54 System Configuration...
Page 55 Advanced Configuration MAC Address Format – MAC addresses can be specified in one of four formats, using no delimeter, with a single dash delimeter, with multiple dash delimeters, and with multiple colon delimeters. VLAN ID Format – A VLAN ID (a number between 1 and 4094) can be assigned to each client after successful authentication using IEEE 802.1X and a central RADIUS server.
Page 56 System Configuration CLI Commands for RADIUS – From the global configuration mode, use the radius-server address command to specify the address of the primary or secondary RADIUS servers. (The following example configures the settings for the primary RADIUS server.) Configure the other parameters for the RADIUS server. Then use the show show radius command from the Exec mode to display the current settings for the primary and secondary RADIUS servers.
Page 57: Ssh Settings
Advanced Configuration SSH Settings Telnet is a remote management tool that can be used to configure the access point from anywhere in the network. However, Telnet is not secure from hostile attacks. The Secure Shell (SSH) can act as a secure replacement for Telnet. The SSH protocol uses generated public keys to encrypt all data transfers passing between the access point and SSH-enabled management station clients and ensures that data traveling over the network arrives unaltered.
Page 58: Authentication
System Configuration CLI Commands for SSH – To enable the SSH server, use the ip ssh-server enable command from the CLI Ethernet interface configuration mode. To set the SSH server UDP port, use the ip ssh-server port command. To view the current settings, use the show system command from the CLI Exec mode (not shown in the following example).
Page 59 Advanced Configuration • The access point can also operate in a 802.1X supplicant mode. This enables the access point itself to be authenticated with a RADIUS server using a configured MD5 user name and password. This prevents rogue access points from gaining access to the network.
Page 60 System Configuration • Radius MAC: The MAC address of the associating station is sent to a configured RADIUS server for authentication. When using a RADIUS authentication server for MAC address authentication, the server must first be configured in the Radius window (see “RADIUS”...
Page 61 Advanced Configuration CLI Commands for Local MAC Authentication – Use the mac-authentication server command from the global configuration mode to enable local MAC authentication. Use the mac-authentication session-timeout command to set the authentication interval. Set the default action for MAC addresses not in the local table using the address filter default command, then enter MAC addresses in the local table using the address filter entry command.
Page 62 System Configuration CLI Commands for RADIUS MAC Authentication – Use the mac-authentication server command from the global configuration mode to enable remote MAC authentication. Set the timeout value for re-authentication using the mac- authentication session-timeout command. Be sure to also configure connection settings for the RADIUS server (not shown in the following example).
Page 63: Filter Control
Advanced Configuration Filter Control The access point can employ network traffic frame filtering to control access to network resources and increase security. You can prevent communications between wireless clients and prevent access point management from wireless clients. Also, you can block specific Ethernet traffic from being forwarded by the access point. Inter Client STAs Communication Filter –...
Page 64 System Configuration • MAC Address: Specifies a MAC address to filter, in the form xx-xx-xx-xx-xx-xx. • Permission: Adds or deletes a MAC address from the filtering table. Ethernet Type Filter – Controls checks on the Ethernet type of all incoming and outgoing Ethernet packets against the protocol filtering table.
Page 65: Vlan
Advanced Configuration VLAN The access point can employ VLAN tagging support to control access to network resources and increase security. VLANs separate traffic passing between the access point, associated clients, and the wired network. There can be a VLAN assigned to each associated client, a default VLAN for each VAP (Virtual Access Point) interface, and a management VLAN for the access point.
Page 66 System Configuration When setting up VLAN IDs for each user on the RADIUS server, be sure to use the RADIUS attributes and values as indicated in the following table. Number RADIUS Attribute Value Tunnel-Type VLAN (13) Tunnel-Medium-Type Tunnel-Private-Group-ID VLANID (1 to 4094 as hexadecimal or string) VLAN IDs on the RADIUS server can be entered as hexadecimal digits or a string (see “radius-server vlan-format”...
Page 67: Wds Settings
Advanced Configuration WDS Settings Each access point radio interface can be configured to operate in a bridge or repeater mode, which allows it to forward traffic directly to other access point units. To set up bridge links between access point units, you must configure the wireless Distribution System (WDS) forwarding table by specifying the wireless MAC address of all units to which you want to forward traffic.
Page 68 System Configuration Spanning Tree Protocol – STP uses a distributed algorithm to select a bridging device (STP-compliant switch, bridge or router) that serves as the root of the spanning tree network. It selects a root port on each bridging device (except for the root device) which incurs the lowest path cost when forwarding a packet from that device to the root device.
Page 69 Advanced Configuration designated ports. After determining the lowest cost spanning tree, it enables all root ports and designated ports, and disables all other ports. Network packets are therefore only forwarded between root ports and designated ports, eliminating any possible network loops. Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the root bridge.
Page 70 System Configuration • Link Path Cost – This parameter is used by the STP to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. (Path cost takes precedence over port priority.) •...

Page 102 System Configuration WPA2 PMKSA Life Time – WPA2 provides fast roaming for authenticated clients by retaining keys and other security settings in a cache for each VAP. In this way, when clients roam back into a VAP they had previously been using, re-authentication is not required.
Page 103 Radio Interface Configuring Rogue AP Detection To configure Rouge AP detection, select the Radio Settings page, and scroll down to the “Rouge AP” section. Rogue AP – A “rogue AP” is either an access point that is not authorized to participate in the wireless network, or an access point that does not have the correct security configuration.
Page 104 System Configuration Note: While the access point scans a channel for rogue APs, wireless clients will not be able to connect to the access point. Therefore, avoid frequent scanning or scans of a long duration unless there is a reason to believe that more intensive scanning is required to find a rogue AP.
Page 105 Radio Interface The access point implements QoS using the Wi-Fi Multimedia (WMM) standard. Using WMM, the access point is able to prioritize traffic and optimize performance when multiple applications compete for wireless network bandwidth at the same time. WMM employs techniques that are a subset of the developing IEEE 802.11e QoS standard and it enables the access point to inter operate with both WMM- enabled clients and other devices that may lack any WMM functionality.
Page 106 System Configuration After a collision detection, a backoff wait time is calculated. The total wait time is the sum of a minimum wait time (Arbitration Inter-Frame Space, or AIFS) determined from the AIFSN, and a random backoff time calculated from a value selected from zero to the CW.

Page 112: Security
System Configuration Security The access point is configured by default as an “open system,” which broadcasts a beacon signal including the configured SSID. Wireless clients with an SSID setting of “any” can read the SSID from the beacon and automatically set their SSID to allow immediate connection to the nearest access point.

Wireless Security Considerations Security Client Support Implementation Considerations Mechanism WPA over 802.1X Requires WPA-enabled system • Provides robust security in WPA-only mode Mode and network card driver (i.e., WPA clients only) (native support provided in • Offers support for legacy WEP clients, but with Windows XP) increased security risk (i.e., WEP authentication keys disabled)
Page 114 System Configuration The access point can simultaneously support clients using various different security mechanisms. The configuration for these security combinations are outlined in the following table. Note that MAC address authentication can be configured independently to work with all security mechanisms and is indicated separately in the table.

SSID – The name of the basic service set provided by a VAP interface. Clients that want to connect to the network through the access point must set their SSID to the same as that of an access point VAP interface.
Page 118 System Configuration • Alphanumeric: Enter keys as 5 alphanumeric characters for 64 bit keys, 13 alphanumeric characters for 128 bit keys, or 16 alphanumeric characters for 152 bit keys. Key Number – Selects the key number to use for encryption for each VAP interface. If the clients have all four keys configured to the same values, you can change the encryption key to any of the eight settings without having to update the client keys.
Page 119 Radio Interface Note: To use 802.1X on wireless clients requires a network card driver and 802.1X client software that supports the EAP authentication type that you want to use. Windows 2000 SP3 or later and Windows XP provide 802.1X client support. Windows XP also provides native WPA support.
