Changing The Switch-To-Client Retransmission Time; Setting The Switch-To-Client Frame-Retransmission Number - Cisco Catalyst 2950 Software Configuration Manual

Chapter 9 Configuring IEEE 802.1x Port-Based Authentication
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.
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3 dot1x timeout tx-period seconds
Step 4
end
Step 5 show dot1x interface interface-id
Step 6 copy running-config startup-config
To return to the default retransmission time, use the no dot1x timeout tx-period interface configuration
command.
This example shows how to set 60 as the number of seconds that the switch waits for a response to an
EAP-request/identity frame from the client before resending the request:
Switch(config-if)# dot1x timeout tx-period 60

Setting the Switch-to-Client Frame-Retransmission Number

In addition to changing the switch-to-client retransmission time, you can change the number of times
that the switch sends an EAP-request/identity frame (assuming no response is received) to the client
before restarting the authentication process.
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.

Purpose
Enter global configuration mode.
Specify the interface to be configured, and enter interface configuration
mode.
Set the number of seconds that the switch waits for a response to an
EAP-request/identity frame from the client before resending the request.
The range is 15 to 65535 seconds; the default is 30.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
