Forwarded to NANOG in the interests of wider awareness... having been
there and torn out my already scarce hair, duplicate MAC addresses can
really mess up your day...

Just when you thought this couldn't happen any more...
Copying from a different email list...
mac address 04:4b:80:80:80:03, was showing up in multiple places
across the network. I googled the mac address and discovered that
other people are having the same issue with this mac address. Below
are some links describing the problem:

I just wanted everyone to know about this problem in case you run
across similar slow "connectivity" issues. I believe the network card
is made by NVIDIA.
