Radio Configuration Chapter 3 Configuration Broadcast WEP Key rotation interval (sec) This option enables broadcast key rotation by setting a key rotation interval. With broadcast, or multicast, WEP key rotation enabled, the access point provides a dynamic broadcast WEP key and changes it at the interval you select. Broadcast key rotation is an excellent alternative to TKIP if your wireless LAN supports wireless client devices that are not Cisco devices or that cannot be upgraded to the latest firmware for Cisco client devices. To enable broadcast key rotation, enter the rotation interval in seconds in the Broadcast WEP Key rotation interval entry field. If you enter 900, for example, the access point sends a new broadcast WEP key to all associated client devices every 15 minutes. To disable broadcast WEP key rotation, enter 0. Note When you enable broadcast key rotation, only wireless client devices using LEAP or EAP-TLS authentication can use the access point. Client devices using static WEP (with open, shared key, or EAP-MD5 authentication) cannot use the access point when you enable broadcast key rotation. Note If you enable Broadcast Key Rotation on one of the radios in a dual-radio access point, Broadcast Key Rotation is automatically enabled on the other radio, also. Accept Authentication Types Select Open, Shared Key, or Network-EAP to set the authentications the access point recognizes. See the "Security Overview" section on page 4-2 for a description of authentication types. Require EAP If you use open or shared authentication as well as EAP authentication, select Require EAP under Open or Shared to block client devices that are not using EAP from authenticating through the access point. 3-38 Cisco Aironet 1200 Series Access Point Software Configuration Guide OL-2159-03
