Ingress DSCP marked IP packets getting dropped on compute

asked 2019-10-17 01:30:47 -0600

we have a open stack cloud created using tripleo. We are getting mirror traffic on our one of VM instance. This mirror traffic will get received on VM if its normal IP packet but when any packet has DSCP marking packets are dropped on bridge interface and after that all traffic is blocked. Not getting any clue why does this happening.

After trying with QoS policy on the port we still see same behaviour. openstack network qos policy create dscp-marking-for-46 openstack network qos rule create --type dscp-marking --dscp-mark 46 dscp-marking-for-46 openstack network qos rule list dscp-marking-for-46 openstack network qos rule show dscp-marking-for-46 d81b3ed3-3a80-4e7b-b16a-0f0743881124

anyone has any idea why this is happening. Thanks in advance.
