show mls qos int stat

hi list

just a quick one but with this command say a trunk link facing another
switch....then no routing protocols running on their and no mcast

well, im trying to figure out what these dscp values are and where they are
generated from....i have debug'd ip pack cannot see any packets being
generated etc

in summary i understand the dscp markings to cos etc but not sure where
they are being generated from and what?

thanks in advance experts.....
