Subject: wrr-queue question
To: Cisco certification <ccielab@groupstudy.com>
Hello all,
is there a way to view counters for traffic hitting the priority and
other queue in a 6748 line cards using wrr queue? I tried the command
show queueing interface gig1/47, and cannot see anything hitting the queue.
I also have avaya phones attached to this port, and have mls qos trust cos
turn on. But I cannot tell if the avaya traffic is hitting the priority
queue or not.
The avaya phones sets both the dscp to ef, and cos to 5. On this port does
it make sense to turn on mls trust cos, or mls trust dscp?
THank you.
