Chapter 6 Configuring IEEE 802.1x Port-Based Authentication

Configuring IEEE 802.1x Authentication

Beginning in privileged EXEC mode, follow these steps to change the quiet period. This procedure is
optional.

To return to the default quiet time, use the no dot1x timeout quiet-period interface configuration
command.

This example shows how to set the quiet time on the switch to 30 seconds:

Switch(config-if)# dot1x timeout quiet-period 30

Changing the Switch-to-Client Retransmission Time

The client responds to the EAP-request/identity frame from the switch with an EAP-response/identity
frame. If the switch does not receive this response, it waits a set period of time (known as the
retransmission time) and then resends the frame.

Note

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.

Beginning in privileged EXEC mode, follow these steps to change the amount of time that the switch
waits for client notification. This procedure is optional.
