Managing 802.1X Encryption Keys 533

Managing 802.1X By default, the WX switch sends encryption key information to a wireless

Encryption Keys supplicant (client) in an Extensible Authentication Protocol over LAN (EAPoL) packet after authentication is successful. You can disable this feature or change the time interval for key transmission.

The secret Wired-Equivalent Privacy protocol (WEP) keys used by MSS on MAPs for broadcast communication on a VLAN are automatically rotated (rekeyed) every 30 minutes to maintain secure packet transmission. You can disable WEP key rotation for debugging purposes, or change the rotation interval.

Enabling 802.1X Key The following command enables or disables the transmission of key Transmission information to the supplicant (client) in EAPoL key messages, after

authentication:

set dot1x key-tx {enable disable}

Key transmission is enabled by default.

The WX switch sends EAPoL key messages after successfully authenticating the supplicant (client) and receiving authorization attributes for the client. If the client is using dynamic WEP, the EAPoL Key messages are sent immediately after authorization.

Type the following command to reenable key transmission:

WX1200# set dot1x key-tx enable success: dot1x key transmission enabled.

Configuring 802.1X

Key Transmission

Time Intervals

The following command sets the number of seconds the WX switch waits before retransmitting an EAPoL packet of key information:

set dot1x tx-period seconds

The default is 5 seconds. The range for the retransmission interval is from 1 to 65,535 seconds. For example, type the following command to set the retransmission interval to 300 seconds:

WX1200# set dot1x tx-period 300 success: dot1x tx-period set to 300.
