Step 6
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
unreliable links or specific behavioral problems with certain clients and authentication servers.
Note
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.
