Changing The Quiet Period - Cisco Catalyst 3550 series Software Configuration Manual

Chapter 9 Configuring 802.1X Port-Based Authentication

Changing the Quiet Period

When the switch cannot authenticate the client, the switch remains idle for a set period of time, and then
tries again. The idle time is determined by the quiet-period value. A failed authentication of the client
might occur because the client provided an invalid password. You can provide a faster response time to
the user by entering a smaller number than the default.
Beginning in privileged EXEC mode, follow these steps to change the quiet period. This procedure is
optional.
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 dot1x timeout quiet-period seconds
Step 4
end
Step 5
show dot1x interface interface-id
Step 6 copy running-config startup-config
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.
You should change the default value of this command only to adjust for unusual circumstances such as
Note
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.

Step 1
