I think we can't change the base ethernet MAC address. In the fixed configuration Catalyst switches MAC addresses cannot be changed.

Thank you both for your helpful replies!

Ankur: It's more a matter of interest than need. As I understand the Bridge ID is derived from the base MAC address of a switch. I was working on a lab scenario were I wanted to alter the choice of root bridge without making changes to any of the spanning-tree parameters.

Cheers, Dirk
