I am trying to apply a service-policy in one of our trunk port. When ever i apply a policy called "service-policy input OFFICE" it removes the other line "mls qos trust dscp" which is found in the trunk for extending the QOS between the devices.
Is there a way to apply both of this lines under a Trunk Port ???
If this is a 3560/3750 switch, we've had a limitation where you cant have both trust and service-policy on an interface.
You can achieve similar functionality by either trusting within your service policy:
Or remarking it to whatever it may have been originally:
set ip dscp ef
Soon, in 12.2(40)SE code, you will be able to have mls trust coexisting with an input service policy. When the code comes out, it will have documentation about what gets priority.
