Configuring 802.1X with Inaccessible Authentication Bypass
Caution You must configure the switch to monitor the state of the RADIUS server as described in the section
Configuring Switch-to-RADIUS-Server Communication, page 49-32 for Inaccessible Authentication
Bypass to work properly. Specifically, you must configure the RADIUS test username, idle-time,
deadtime and dead-criteria. Failure to do so results in the switch failing to detect that the RADIUS server
has gone down, or prematurely marking a dead RADIUS server as alive again.
