dot1x timeout
Command History
Usage Guidelines You should change the default value of this command only to adjust for unusual circumstances such as
unreliable links or specific behavioral problems with certain clients and authentication servers.
The dot1x timeout reauth-period interface configuration command affects the behavior of the switch
only if you have enabled periodic re-authentication by using the dot1x reauthentication interface
configuration command.
During the quiet period, the switch does not accept or initiate any authentication requests. If you want
to provide a faster response time to the user, enter a number smaller than the default.
When the ratelimit-period is set to 0 (the default), the switch does not ignore EAPOL packets from
clients that have been successfully authenticated and forwards them to the RADIUS server.
Examples This example shows how to enable periodic re-authentication and to set 4000 as the number of seconds
between re-authentication attempts:
Switch(config-if)# dot1x reauthentication
Switch(config-if)# dot1x timeout reauth-period 4000
This example shows how to enable periodic re-authentication and to specify the value of the
Session-Timeout RADIUS attribute as the number of seconds between re-authentication attempts:
Switch(config-if)# dot1x reauthentication
Switch(config-if)# dot1x timeout reauth-period server
This example shows how to set 30 seconds as the quiet time on the switch:
Switch(config-if)# dot1x timeout quiet-period 30
This example shows how to set 45 seconds as the switch-to-authentication server retransmission time:
Switch(config)# dot1x timeout server-timeout 45
This example shows how to set 45 seconds as the switch-to-client retransmission time for the EAP
request frame:
Switch(config-if)# dot1x timeout supp-timeout 45
This example shows how to set 60 as the number of seconds to wait for a response to an
EAP-request/identity frame from the client before re-transmitting the request:
Switch(config-if)# dot1x timeout tx-period 60
This example shows how to set 30 as the number of seconds that the switch ignores EAPOL packets from
successfully authenticated clients:
Switch(config-if)# dot1x timeout ratelimit-period 30
You can verify your settings by entering the show dot1x privileged EXEC command.
