i am trying to get the 802.1x authentication working between windows xp computer and switch c3560 using ACS 3.2.

ip address is static in this first step, just trying to be authenticated by radius ietf.

but in acs i got this error in Failed Attempts :

Bad request from NAS .. .. .. Invalid message authenticator in EAP request.

Your config seems to be fine and you are missing just one command. Please try to setup the command " ip radius source-interface Vlan1 " and check if that works.


HTH, Please rate if it does.
