We have a 6504 switch with supervisor 720 10GE as core/distribution. We do marking at access level on 2960. I see drops on core. So I need to know about something like mls qos int stat, but on 6500. Please help.

Here are a few to try-

show queueing interface xxx

show mls qos detailed

show int st (generally useful to see that everything is fast switched)

show interfaces utilization xxx

if applied, the show policy-map and show class-map may also give useful information.

It's less likely as an issue, but the various fabric stats can also provide some info. Go for show fabric utilization, show fabric channel-counters among others.
