Re: to the dot1x gurus..any input, appreciated !!!

Charlie,

What EAP method are you doing on the dot1x client? MD5, PEAP or TLS? Have
you configured certificates, etc, on client and server?

Seems to be like you dont have a supplicant on the port? See below:

May 5 09:18:48.629: %AUTHMGR-7-RESULT: Authentication result 'no-response'
from 'dot1x' for client (Unknown MAC) on Interface Fa0/1

All EAP Request Identity frames seem to be getting ignored by the client.
This comes down to what you have configured as an EAP method. Are you
getting a password prompt on the client?

Can we see a full running configuration?

Thanks,
Sadiq
