Cisco me 3400 Guia De Referência

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.

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 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

You can verify your settings by entering the show dot1x privileged EXEC command.

Sets the maximum number of times that the switch sends an 
EAP-request/identity frame before restarting the authentication process.

Enables periodic re-authentication of the client.

Displays IEEE 802.1x status for all ports.
