I have an ACS and two switches. they are configured for 802.1x. 2950 works fine but 2960 does not work. I see an error message "Invalid message authenticator in EAP request"
what does this mean? They have the same configuration.
I've seems some similar issue, make sure that you have IOS ver 12.1(22)EA10 or above installed.
