Can you be more specific? Which are you interested in - SVIs or routed 
ports? They behave differently.

On 6500/sup720 for example, SVIs have the common chassis MAC address, 
whereas routed ports or sub-interfaces have the per-port MAC address 
(note that if you have >1 sub-int on a port, they share the same MAC)

Likewise on 3550s, SVIs have the same MAC. I'm not sure about routed 
ports as we don't have any in service, but I'd expect the behaviour to 
be the same.
