CHAPTER 5: COMMAND LINE INTERFACE • When 802.1X is required, the access point enforces 802.1X authentication for all 802.11 associated stations. If 802.1X authentication is not initiated by the station, the access point will initiate authentication. Only those stations successfully authenticated with 802.1X are allowed to access the network. • 802.1X does not apply to the 10/100Base-TX port. Example Enterprise AP(config)#802.1x supported Enterprise AP(config)# 802.1x broadcast-key-refresh-rate This command sets the interval at which the broadcast keys are refreshed for stations using 802.1X dynamic keying. Syntax 802.1x broadcast-key-refresh-rate rate - The interval at which the access point rotates broadcast keys. (Range: 0 - 1440 minutes) Default Setting 0 (Disabled) Command Mode Global Configuration Command Usage • The access point uses Enterprise APOL (Extensible Authentication Protocol Over LANs) packets to pass dynamic unicast session and broadcast keys to wireless clients. The 802.1x broadcast-key-refresh-rate command specifies the interval after which the broadcast keys are changed. The 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. Example Enterprise AP(config)#802.1X broadcast-key-refresh-rate 5 Enterprise AP(config)# 5-72
