We have some problems with 802.1x port authentication after updating the Cisco IOS to 12.2(35)SE5.
First there was the IOS 12.2(25r)SEC on the cisco switch 3560 and the port authentication is working. I can see, that the Cisco sends "EAP Request Identity" Version 1 to the network device. After the network device has answered the request identity, the cisco starts to communicate with the radius server. Everything is working!
After I have updated the Cisco to IOS 12.2(35)SE5 I can see, that the Cisco sends a "EAP Request Identity" Version 2 to the network device. The network device can not answer this request, and there is no more communication, so the port is shutdown.
Is there any possibility to change the Version of the EAP Request in the Cisco?
Thanks a lot for your help!
