QoS on a 5548 vPC

[Steven Iannetta]

I know this is basic, but I am configuring a input service policy to mark bulk traffic into the af11 traffic class via a dscp code 10 polciy on a 5548 with a vPC config below:

interface port-channel7

  switchport access vlan 577

  speed 1000

  service-policy type qos input PGR-mark-af11

  vpc 7

policy-map type qos PGR-mark-af11

    class type qos PGR-bulk-transfer

      set dscp 10

    class type qos class-default

      set qos-group 0

class-map type qos match-any PGR-bulk-transfer

      match access-group name ACL_qos_nbu_boost

IPV4 ACL ACL_qos_nbu_boost

        10 permit tcp any any eq 2049

        20 permit tcp any eq 2049 any

        30 permit tcp any any eq 2051

        40 permit tcp any eq 2051 any

        50 permit tcp any any eq sunrpc

        60 permit tcp any eq sunrpc any

        70 permit tcp any any eq 1556

        80 permit tcp any any eq 13724

Problem is  the traffic is not matching the dscp policy all traffic is best effort.

I aslo tried adding the policy to the individual ethernet interfaces and recived the error "Service policy not allowed on port channel members"

Any help?

Did you configure it on both N5Ks? The two switches in a vPC domain have their own control planes.

You can check it by entering the show vpc consistency-parameters global and the show vpc consistency-parameters interface port-channel 7 command.

[Steven Iannetta]

yes it is configured on both 5k's.

Are there any hits on the ACL?

[Steven Iannetta]

no hits on the acl

You should take a packet capture on the interface to make sure the traffic really passes.
