The cisco-nsp mailing list had a query about this problem: http://puck.nether.net/lists/cisco-nsp/0318.html But I don't know whether this has been resolved. If I try outbound MAC accounting (usually I only use inbound MAC accounting at exchange points) on a 7206VXR running 12.0(17)S, everything looks fine. > 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. (Maybe your Cisco multicasts all traffic out to the exchange point rather than send it to the correct peer - seems much more robust to me, although you might end up with heavy packet replication :-) -- Simon Leinen email@example.com SWITCH http://www.switch.ch/misc/leinen/ Computers hate being anthropomorphized.
