Base MAC address for Cisco Routers?

Unanswered Question
Apr 14th, 2007

Do routers have a base MAC like Catalyst switches do? Or are the only MAC/Hardware address available per interface?


I have this problem too.

Hi Chris,

Each interface has a specific MAC address defined in case of routers.

A router does have something called as the Chassis MAC Address but not sure whether it can be called as base mac address.

You can see this mac-address by the sh diag command

HTH, rate if it does
