Default QOS behaviour Nexus 7000

We are monitoring ingress & egress traffic on a Layer 3 subinterface on Port Channel port in Nexus 7000. The mirror capture is based on filtering with any ip traffic on that port with "dscp=ef"

In the present node config, I dont see any config command where any keyword like qos, cos, tos etc are used. sh table-map shows below :

 

show table-map

  Table-map cir-markdown-map
    default copy
    from 10,12 to 12
    from 18,20 to 20
    from 26,28 to 28
    from 34,36 to 36

  Table-map pir-markdown-map
    default copy
    from 10,12 to 14
    from 18,20 to 22
    from 26,28 to 30
    from 34,36 to 38

  Table-map cos-dscp-map
    default copy

 

The problem is I dont see any mirrored traffic which is actually egress. I see all ingress frame on that port in mirror traffic output.

 

Any reasons....

Hello,

 

what are you using for the mirroring, SPAN ? If so, according to the documentation below, Layer 3 subinterfaces are not supported.
