[. . . ] · Broadcast Key Refresh Rate: Sets the interval at which the broadcast keys are refreshed for stations using 802. 1X dynamic keying. (Range: 0-1440 minutes; Default: 0 means disabled) · Session Key Refresh Rate: The interval at which the access point refreshes unicast session keys for associated clients. (Range: 0-1440 minutes; Default: 0 means disabled) 6-87 6 System Configuration · 802. 1X Reauthentication Refresh Rate: The time period after which a connected client must be re-authenticated. During the re-authentication process of verifying the client's credentials on the RADIUS server, the client remains connected the network. Only if re-authentication fails is network access blocked. (Range: 0-65535 seconds; Default: 0 means disabled) CLI Commands for 802. 1X Authentication ­ Use the 802. 1X supported command from the VAP interface mode to enable 802. 1X authentication. Set the session and broadcast key refresh rate, and the re-authentication timeout. To display the current settings, use the show interface wireless command from the Exec mode (not shown in the example).

Ethernet MAC: The physical layer address for the Ethernet port. Radio A MAC: The physical layer address for the 802. 11a interface. Radio G MAC: The physical layer address for the 802. 11b/g interface. System Name: Name assigned to this system. System Contact: Administrator responsible for the system. IP Address: IP address of the management interface for this device. IP Default Gateway: IP address of the gateway router between this device and management stations that exist on other network segments. HTTP Server: Shows if management access via HTTP is enabled. HTTP Server Port: Shows the TCP port used by the HTTP interface. Software Version: Shows the software version number. Bootrom Version: Show the bootrom version number. Hardware Version: Shows the hardware version number. 6-89 6 System Configuration AP Wireless Configuration ­ The AP Wireless Configuration tables display the radio and VAP interface settings listed below. Note that Interface Wireless A refers to the 802. 11a radio and Interface Wireless G refers the 802. 11b/g radio. · SSID: The service set identifier for the VAP interface. [. . . ] IEEE 802. 11 specifies two forms of authentication: open system and shared key. Backbone The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is unloaded onto a local system. Basic Service Set (BSS) A set of 802. 11-compliant stations and an access point that operate as a fully-connected wireless network. Beacon A signal periodically transmitted from the access point that is used to identify the service set, and to maintain contact with wireless clients. Glossary-1 Glossary Broadcast Key Broadcast keys are sent to stations using 802. 1X dynamic keying. Dynamic broadcast key rotation is often used to allow the access point to generate a random group key and periodically update all key-management capable wireless clients. CSMA/CA Carrier Sense Multiple Access with Collision Avoidance. Dynamic Host Configuration Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Encryption Data passing between the access point and clients can use encryption to protect from interception and evesdropping. Extended Service Set (ESS) More than one wireless cell can be configured with the same Service Set Identifier to allow mobile users can roam between different cells with the Extended Service Set. Extensible Authentication Protocol (EAP) An authentication protocol used to authenticate network clients. [. . . ]
