Setting the Switch-to-Client Frame-Retransmission Number
In addition to changing the switch-to-client retransmission times, you can change the number of times that the switch sends
EAP-Request/Identity and other EAP-Request frames to the client before restarting the authentication process. The number of
EAP-Request/Identity retransmissions is controlled by the dot1x max-reauth-req command; the number of retransmissions
for other EAP-Request frames is controlled by the dot1x max-req command.
You should change the default values of these commands only to adjust for unusual circumstances such
Note
as unreliable links or specific behavioral problems with certain clients and authentication servers.
