The best method would be to isolate those devices on a single vlan and use port security for everything on that vlan.

I have a small number of some critical network devices that I'd like to make sure cannot have their mac addresses spoofed or usurped due to loops or other network causes. How would this work? I have a 3560 with ipbase software.
