Error %DOT1X-5-FAIL with ISE

Pegasusxl666
Level 1
Level 1

Hi community 

 

I have a doubt, I replace the network admin and doing a check of logs I run into with the log "%DOT1X-5-FAIL: Switch 1 R0/0: sessmgrd: Authentication failed for client (ace2.d309.6976) with reason (No Response from Client) on Interface Gi1/0/3 AuditSessionID A17D070A000000884B8C597E"

 

My question is about the origin of log, It's a good o bad?

 

I share you the information:

 

interface GigabitEthernet1/0/3
description ISE dot1x Port

Hi

 

Is the log no-response from client shown multiple times or 1 time?

what do you mean by changed network admin?

 

The log says the client didn't gave any dot1x response and the session was failed due to that time out.

However, on the next outputs, we see that same mac, same port in AUTH state so it is actually authenticated.


Thanks
Francesco

Hello yes I mean that I replaced the old network administrator.

My query is why does the dot1x message come out every hour on the switch, if I understand it has already been authenticated, is this behavior normal? according to the configuration shown above

messages aren't supposed to be here if everything works as expected. in your case, the client doesn't respond to dot1x requests.

 

can you share the output of show authentication session details for that port?

 

also as it's coming every hour, can you run a tcpdump on ise prior to the log to come in and share the capture?


Thanks
Francesco
