Usage
Information
When you configure the dot1x server-timeout value, take into account the
communication medium used to communicate with an authentication server and
the number of RADIUS servers configured. Ideally, the dot1x server-timeout
value (in seconds) is based on the configured RADIUS-server timeout and
retransmit values and calculated according to the following formula: dot1x
server-timeout
seconds > (radius-server retransmit seconds + 1) * radius-server
timeout seconds.
Where the default values are as follows: dot1x server-timeout (30 seconds),
radius-server retransmit (3 seconds), and radius-server timeout (5 seconds).
For example:
Dell(conf)#radius-server host 10.11.197.105 timeout 6
Dell(conf)#radius-server host 10.11.197.105 retransmit 4
Dell(conf)#interface tengigabitethernet 2/23
Dell(conf-if-te-2/23)#dot1x server-timeout 40
dot1x supplicant-timeout
Configure the amount of time after which exchanges with the supplicant time-out.
