QoS colouring Nexus 5500 - no matches on ACL

[mjauner]

Hello

We are Migrating some VoIP - Servers from old Cat 4506 Switch to Nexus Infrasrtructure.

For the Voice-Servers we colour voice trough the network.

We configured same way as on 4506. On 4506 we can check matches in ACL to prove that configuration fit.

Same command on 5596 never show matches on ACL.

What may be our problem?

Thanks for ideas.

show policy-map interface po 41

show queueing interface
