Hello Group,
Can someone confirm the behaviour i'm seeing ?
In the 3560 when i change one port from L2 to L3 i get a new mac-address and
each will port will have it's own Mac.
In the 3550 when i change from L2 to L3 the Mac-Address is changed to the
Base Mac-Address. But here two ports will have the same Mac.
