Nexus 9K Re-marking of CS6 Control-Plane Traffic

[MATTHIAS SCHAERER]

I assume that it's not possible but I ask anyway:

I'd like to remark my CS6 routing traffic in a Nexus 9372/NXOS: version 7.0(3)I5(1) to COS5 on L2. Does anybody have an idea how to do this (Output qos policies seem not to be allowed on L2 interfaces/How to catch Control-plane traffic qos-wise to remark it?).

Or if somebody knows definitely that it is not possible he/she may convince me to stop searching.

Thanks anyway!

I believe you can do this with a policy-map.
1. configure terminal

2. policy-map [type qos] [match-first] [qos-policy-map-name | qos-dynamic]

3. class [type qos] {class-map-name | class-default} [insert-before before-class-name]

4. set cos cos-value

The first part of MQC is clear to me, it gets interesting when you have to issue the service-policy command. Where would you set that one? If I assign it as an output policy I get:

ERROR: Cannot apply output qos policy to interface: Ethernet111/1/48

And where I could catch the input traffic is also not clear to me since it is originated by the box itself.

With the Nexus 9k line you can only mark on ingress.
