Cat9x00 QoS: set dscp AND qos-group

[MATTHIAS SCHAERER]

Is it possible to set IP DSCP and QoS-group in the same policy map for the same traffic class? As IP DSCP is marked inside the packet and QoS group is a specific local header to the device.

I have only used qos-group in limited situations, but it isn't something that is changed in the packet itself. It is an internal tag that only lives in that one device. You could tag a QoS group on input from one place, and then use that QoS group as part of an output policy. The DSCP/IP Precedence is something entirely different.
