mac-address accounting

  • From: Alex Rubenstein

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.

Then, I:

core1.nyc#sho int g0/0/0 mac-accounting
GigabitEthernet0/0/0 to external peers and customers
  Output  (475 free)
    0001.64da.bc00(3  ):  2 packets, 179 bytes, last: 3036ms ago
    0004.de2b.e41c(9  ):  1 packets, 99 bytes, last: 3036ms ago
    00e0.52a6.1f00(11 ):  1 packets, 99 bytes, last: 3036ms ago
    0100.0c00.0000(13 ):  57198 packets, 37155973 bytes, last: 388ms ago
    0030.7bee.fc54(13 ):  2 packets, 218 bytes, last: 2836ms ago


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
core1.nyc#

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.
