QoS on IOS-XE 17.12 Max of One Set action inside policy-map

[j.a.m.e.s]

I'm trying to classify incoming traffic into a QoS-Group and Mark the DSCP at the same time in IOS-XE. We've been doing this for many years on NXOS, but annoyingly it looks like this isn't possible with IOS-XE:

class-map match-any CM-QOS-VIDEO
 match dscp af41 cs4
exit
[...]

policy-map PM-QOS-IN
 [...]
 class CM-QOS-VIDEO
  set qos-group 6
  set dscp 34       ! consolidate to af41
  063645: Mar 3 10:00:03.137 EST: Multiple set actions in the same class is not supported
  [...]
exit

Does anyone know if later versions of IOS-XE might support this or any other workarounds? Maybe in the output queueing policy we could mark the new DSCP?

It seems odd that Cisco would introduce features like being able to set a qos-group or traffic-class etc, but limit us to a single set action per policy-map class.

Why are you setting the qos-group? That is, are you matching on qos-group in an egress policy?

Also, what XE platform is this?

[j.a.m.e.s]

Yes, exactly that, where a qos-group corresponds to one of the output queues.

Thus implying same DSCP egress marked traffic might have different egress treatment, correct?

If correct, somewhat unusual but not necessarily "bad", if fact, could be very useful.

[j.a.m.e.s]

Yes, that's what we've been doing in NXOS for many years and I thought finally IOSXE might offer the same flexibility, so that we could unify the config, but it seems not.

Also, it makes more logical sense to be marking DSCP on ingress rather than egress.

"Maybe in the output queueing policy we could mark the new DSCP?"

That's what I would have suggested.
