Hi group.
My question is:
If I have both COS and DSCP fields set, with CoS=3 and DSCP=24, and I have
both DSCP and COS output queue maps like so:

mls qos srr-queue output cos-map queue 2 3
mls qos srr-queue output dscp-map queue 3 24

Which output queue will the packet fall in to?

I know what will happen if this would be an input (trust option) but there
is no such thing as trust on the output, after Internal DSCP has been
consulted. So how is it decided in this case?

Thanks.

P.S.: Interface is trunk and does have 802.1q/802.1p. There are no counters
that would show the queue match, for example "show mls qos interface x/x
statistics" shows output VALUES, not queues. But i know the values exactly
and need to know output queues.
