The 2.4 GHz/5 GHz Wireless Access Point also provides repeater and bridging services that can be configured independently on either the 5 GHz or 2.4 GHz radio interfaces. Access points can be deployed to support wireless clients and connect wired LANs in the following configurations: •...
Page 43: 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 44: Infrastructure Wireless Lan
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 45: 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 46: 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 either the 5 GHz (802.11a) or 2.4 GHz (802.11b/g) bands and can be used with various external antennas to offer flexible deployment options.
Page 47: 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 48: Chapter 5: Initial Configuration
Chapter 5: Initial Configuration The 2.4 GHz/5 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.

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 56: Tcp / Ip Settings
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 57 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 58: Radius
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 59 System Configuration...
Page 60 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 61 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 62: Ssh Settings
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 63: 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 64 MAC Authentication – You can configure a list of the MAC addresses for wireless clients that are authorized to access the network. This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the access point or remotely on a central RADIUS server.
Page 65 System Configuration 802.1X Supplicant – 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 66 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, and web-redirect command to enable web-based authentication for service billing. 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 67 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 68: Filter Control
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 71: Vlan
System 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 72 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 Tunnel-Type Tunnel-Medium-Type Tunnel-Private-Group-ID VLAN IDs on the RADIUS server can be entered as hexadecimal digits or a string (see “radius-server vlan-format”...
Page 73: Wds Settings
System 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 74 • Bridge: Operates as a bridge to other access points. The “Parent” link to the root bridge must be configured. Up to five other ”Child” links are available to other bridges. • Repeater: Operates as a wireless repeater, extending the range for remote wireless clients and connecting them to the root bridge.
Page 75 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 76 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 77 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 78 CLI Commands for STP Settings – If the role of a radio interface is set to Repeater, Bridge or Root Bridge, STP can be enabled on the access point to maintain a valid network topology. To globally enable STP, use the bridge stp enable command from the CLI configuration mode.
Page 79: Ap Management
System Configuration AP Management The Web, Telnet, and SNMP management interfaces are enabled and open to all IP addresses by default. To provide more security for management access to the access point, specific interfaces can be disabled and management restricted to a single IP address or a limited range of IP addresses.

Page 210: 802.1X Authentication
802.1X Authentication The access point supports IEEE 802.1X access control for wireless clients. This control feature prevents unauthorized access to the network by requiring an 802.1X client application to submit user credentials for authentication. Client authentication is then verified by a RADIUS server using EAP (Extensible Authentication Protocol) before the access point grants client access to the network.
Page 211: 802.1X Broadcast-Key-Refresh-Rate
Command Line Interface Command Mode Global Configuration Command Usage • When 802.1X is disabled, the access point does not support 802.1X authentication for any station. After successful 802.11 association, each client is allowed to access the network. • When 802.1X is supported, the access point supports 802.1X authentication only for clients initiating the 802.1X authentication process (i.e., the access point does NOT initiate 802.1X authentication).
Page 212: 802.1X Session-Key-Refresh-Rate
command specifies the interval after which unicast session keys are changed. • Dynamic broadcast key rotation allows the access point to generate a random group key and periodically update all key-management capable wireless clients.

Command Line Interface VLAN Commands The access point can enable the support of VLAN-tagged traffic passing between wireless clients and the wired network. Up to 64 VLAN IDs can be mapped to specific wireless clients, allowing users to remain within the same VLAN as they move around a campus site.
Page 278: Management-Vlanid
• Traffic entering the Ethernet port must be tagged with a VLAN ID that matches the access point’s native VLAN ID, or with a VLAN tag that matches one of the wireless clients currently associated with the access point.

Page 279: Wmm Commands
Command Line Interface Default Setting Command Mode Interface Configuration (Wireless-VAP) Command Usage • To implement the default VLAN ID setting for VAP interface, the access point must enable VLAN support using the vlan command. • When VLANs are enabled, the access point tags frames received from wireless clients with the default VLAN ID for the VAP interface.
Page 280: Wmm
This command sets the WMM operational mode on the access point. Use the no form to disable WMM. Syntax [no] wmm <supported | required> • supported - WMM will be used for any associated device that supports this feature. Devices that do not support this feature may still associate with the access point.

Command Line Interface interpretability with other wired network QoS policies. While the four ACs are specified for specific types of traffic, WMM allows the priority levels to be configured to match any network-wide QoS policy. WMM also specifies a protocol that access points can use to communicate the configured traffic priority levels to QoS-enabled wireless clients.
