[c-nsp] port security / prevent learning mac address

[Mack McBride]

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

Hello,

	Is there a cisco feature that will learn a mac address on a port, and then refuse to learn that mac address from any other source? 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.

Mike-
