Nexus 7018 F2 Card COS to Queue Mapping

[rick505d3]

Hi,

The default COS mapping for F2 card with egress queuing 1P3Q1T is:

    # show class-map

   class-map type queuing match-any 1p3q1t-8e-out-pq1
      Description: Classifier for Egress Priority queue 1 of type 1p3q1t8e
      match cos 5-7

    class-map type queuing match-any 1p3q1t-8e-out-q2
      Description: Classifier for Egress queue 2 of type 1p3q1t8e
      match cos 3-4

    class-map type queuing match-any 1p3q1t-8e-out-q3
      Description: Classifier for Egress queue 3 of type 1p3q1t8e
      match cos 2

    class-map type queuing match-any 1p3q1t-8e-out-q-default
      Description: Classifier for Egress queue 4 of type 1p3q1t8e
      match cos 0-1

The requriement is to override the default values to this:

class-map type queuing match-any 1p3q1t-8e-out-pq1 
    match cos 4-5
class-map type queuing match-any 1p3q1t-8e-out-q2 
    match cos 6-7
class-map type queuing match-any 1p3q1t-8e-out-q3 
    match cos 2-3
class-map type queuing match-any 1p3q1t-8e-out-q-default 
    match cos 0-1

However, it gives the following error on application:

"ERROR: Changing egress cos2q map towards non default fault value is not allowed with M-series card present in the system"

We have combination of M1, M2 and F2 cards in the same chassis Nexus 7018 running 6.1(4a).

Is there a way around the error ? In particular, how to map COS 4 (VidConf/RT Interactive traffic) to PQ1.

Thanks, 

Rick.

The default queuing policies cannot be modified directly. There are two options that you can try:

1. Copy the default policy to a new policy and then modify the new policy.

2. Define a new policy with a unique name and apply it.
