[c-nsp] Cat 6500 and 3550 QOS stats

[Church, Chuck]

Anyone,
 
    I'm working in a lab environment where we're using an Ixia traffic
generator to load up some LAN segments alongside some Avaya IP telephony
traffic.  Supposedly the phones are using dot1P tags of COS 6, and IP
DSCP 46 on the layer 3 side.  I'm seeing drops during the tests of these
packets.  My QOS settings aren't seeming to help much, so I'm
questioning the tagging at layer 2 and 3 of the phones themselves.  My
question is; is there anyway to gather stats on what DSCP and dot1P tags
the ports are seeing in both CatOS for the 6500 and IOS for the 3550?
I've looked through the various show qos and mls commands, but don't see
anything that'll tell me if any dot1p-tagged frames are being received.
 
Thanks in advance,
