I'm using MAC accounting on our Fast E connection at the PAIX to do per-peer traffic stats. It worked great until we put in a GSR. I don't know why it worked before or if anything has changed since.
When Cisco released the GSR platform, the dropped MAC accounting from the requirements on all their ethernet boards for that platform. While you could turn it on, the counters were meaningless, sometimes showing you nothing, often showing packets on the wrong bucket. The short story is that "processor switched" packets were counted correctly, but there was no implementation for "ASIC switched" packets, and so they incremented some generic counter. Several people, including myself made a big stink about this issue. My biggest complaint was if they weren't going to implement it, then you shouldn't be able to configure it in the CLI, but that said, it should be implemented. Fortunately Cisco was helpful, and decided to work on implementing it. Support for the 1xGE card was added in 12.0(11) I believe. They just added support for the 3xGE card in 12.0(13). I have never asked myself about the FE cards, but they should be more or less the same issue. If you're not on fairly recent code I recomend trying an upgrade and seeing if that fixes your problem. If not, you should open a tac case for the bug "mac accounting can be configured on FE, but does not work". If you can't get some good answers e-mail me and I'll poke some of the people we've been working with. -- Leo Bicknell - bicknell@ufp.org Systems Engineer - Internetworking Engineer - CCIE 3440 Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org
