QoS colouring Nexus 5500 - no matches on ACL

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?

Nexus5596

----------------

ip access-list VOICE_MARKING

  1 permit udp 10.50.0.0/15 10.50.0.0/15 gt 32511

  2 permit udp 10.50.0.0/15 10.50.0.0/15 range 16384 16482

class-map type qos match-all VOICE

  match access-group name VOICE_MARKING

policy-map type qos AS-QOS

  class VOICE

    set dscp 46

  class class-default

    set dscp 0

interface port-channel41

  description s0zh-bl1s1 p41

  switchport mode trunk

  ip dhcp snooping trust

        1 permit udp 10.50.0.0/15 10.50.0.0/15 gt 32511

        2 permit udp 10.50.0.0/15 10.50.0.0/15 range 16384 16482

Cat 4506

-------------

4506#sh access-lists

Extended IP access list 146

    10 permit udp 10.50.0.0 0.1.255.255 10.50.0.0 0.1.255.255 gt 32511 (59773751881 matches)

    20 permit udp 10.50.0.0 0.1.255.255 10.50.0.0 0.1.255.255 range 16384 16482 (782457110 matches)

Thanks for ideas.
