Hmmm...answering my own question, it looks like the marking is actually working! In a forehead-slapping moment, I just realized that it's the command we use to check that isn't working. We use "show mls qos interface xyz stat" to see the count of packets with various markings. It makes sense that if mls qos is disabled, a "show mls qos" command isn't going to work the way we want. Does that sound right? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
