Hi Experts

I want to classify traffic by using class-maps in a Catalyst C2960S but it doesn't work (class-maps doesn´t match any traffic)

RH0A01-SW1#show policy-map interface GigabitEthernet1/0/34
GigabitEthernet1/0/34

  Service-policy input: QoS_Standard

    Class-map: VoIP (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group name trafico-VoIP

    Class-map: VideoConferencia (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group name trafico-VideoConferencia

    Class-map: CCTV (match-all)
      0 packets, 0 bytes

      Match: access-group name trafico-CCTV

    Class-map: Servicios_Criticos (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps

Why are class-maps  not matching any traffic?

Thank you in advance.

"show policy-map interface" in 2960, 2970, 3560, 3750 should give error

Symptom: "show policy-map interface"  shows no matches Conditions: This command is run on one of the following switches: 2950 2960 2970 3550 3560 3750 Workaround: This is a hardware limitation and these switches do not support this output.  There is no workaround.

Thank you for your answer Edison.

Although the "show policy-map interface" command is not supported, my QoS policy  is working. Isn`t it ?

Thank you

If it matches the ACL, it should.

You can verify this by spanning the egress port on this switch and sniff the packets.

The packets should contain the corresponding markings.
