Unable to apply qos policy with dscp marking rule to a port

[Vamsi Krishna]

1.Create a Qos Policy
2.Create a dscp marking rule on to create qos policy
3.Apply above created policy to a port

openstack port qos rule set --dscp-mark 22 dscp-marking 115e4f70-8034-41768fe9-2c47f8878a7d

HttpException: Conflict (HTTP 409) (Request-ID: req-da7d8998-9d8c-4aea-a10b-326cc21b608e), Rule dscp_marking is not supported by port 115e4f70-8034-41768fe9-2c47f8878a7d

stack@pike-ctrl:~/devstack$

Seeing above error during the qos policy application on a port.

Any suggestions on this ?

I see below review has been abandoned which is "Allow networking-odl to support DSCP Marking rule for qos driver":

https://review.openstack.org/#/c/460470/

Is dscp marking supported in PIKE ?

Thanks,
Vamsi

As You can check in https://github.com/openstack/networking-odl/blob/master/networking_odl/qos/qos_driver_v2.py#L33 networking-odl qos driver supports currently only bandwidth limit rule so You will be able to attach to such ports only QoS policy with such rule types.

I'm not networking-odl developer so I can't tell if it is planned or not to add support for DSCP marking rules there.
