MAC based authentication for switches using ACS

I would like to know what I would need as far as an ACS server to allow and disallow people from connecting to the switches based on their mac address. I have a customer who has WYSIWYG terminals and cannot add any time of software for authentication purposes to them. Basically if it does not have a matching mac address in the list, it cant connect. I know this can be done at the switch itself, but can this also be done through an ACS server, and also can the server use a BAT type file to add the MAC addresses? I believe we are looking at 802.1x for this. These are 3550 or 60 switches.

It sounds like you need the MAC-Authentication-Bypass feature on these switches.

Go here for the config guide to get started:


Hope this helps,
