Many thanks to all who replied. While I am now assured that nothing is wrong,
I am still perplexed.
My original question was that I had the same ethernet MAC address on two
physical interfaces, when my understanding was that interfaces had unique
addresses assigned by the manufacturer.
All of the responses said that the ethernet address was loaded from an ID
in the prom and was set on all the interfaces. Since the interfaces are on
separate physical wires, the requirement that the address be unique on a wire
This brings up some questions in my mind. What about rarp requests? If the
interfaces have the same MAC address and different IP address, doesn't this
screw up the rarp protocol? How to you enter the addresses in the ethers file?
BTW, some of you thought the two interfaces were on the same physical wire, but
that was not the case.
