Perhaps I am using this feature wrong, but I don't think so.
This morning, I am trying to get mac-address accounting working on a
7507MX/RSP8/12.0.17S/GEIP+ running ISL, to indentify large peers off an
ethernet peering fabric.
I've done 'ip accounting mac-address out'. I then wait.
core1.nyc#sho int g0/0/0 mac-accounting
GigabitEthernet0/0/0 to external peers and customers
Output (475 free)

All of the mac-addresses listed in this 'sho' are valid, except for
'0100.0c00.0000', which doesn't exist:
core1.nyc#sho arp | inc 0100
All the others are valid, yet they are way, and I mean *way* under the
amounts that I know I am sending to that peer.
Any clues? I've searched CCO/Bug Toolkit, I don't see anything relevant.
