Hello Sandeep,

I found this syslog on WLC,DOT1X-4-MAX_EAP_RETRANS: 1x_ptsm.c:528 Max EAP retransmissions exceeded for client 94:65:9c:55:f3:ed.

Hi,

Hi,

We need more of the debug to be able to find the exact root cause of the problem.

DOT1X-4-MAX_EAP_RETRANS: 1x_ptsm.c:528 Max EAP retransmissions exceeded for client 94:65:9c:55:f3:ed.

This means, the WLC has sent an EAP request to the client, and has not received a response. This could be because either the client didn't hear the request, or the AP didn't hear the response. It could also be the client ignored the request.
