Configuring 802.1X Authentication
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 retransmits 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:
To return to the default retransmission time, use the no dot1x timeout tx-period global 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 retransmitting the request:
Switch(config)# dot1x timeout tx-period 60
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
dot1x timeout tx-period seconds
Set the number of seconds that the switch waits for a response to an
EAP-request/identity frame from the client before retransmitting the
request.
The range is 1 to 65535 seconds; the default is 30.
Step 3
end
Return to privileged EXEC mode.
Step 4
show dot1x
Verify your entries.
Step 5
copy running-config startup-config
(Optional) Save your entries in the configuration file.
