Warning: "Cannot configure PCP and DSCP maps together, ignoring PCP map"

Condition

This warning means that the system will ignore your PCP map configuration, and it will enqueue packets onto profile queues on the basis of the DSCP values of the packets.

If you want the system to classify packets by the PCP value of the frame at the third stage, then you must fix this warning.

Cause

You tried to configure both a DSCP and a PCP map.

You will trigger this warning if you combine two commands like these in your configuration:

set policy qos name <policy-name> shaper profile <profile-name> map dscp <value> to <queue-id>
set policy qos name <policy-name> shaper profile <profile-name> map pcp <value> to <queue-id> 

Remedy

Apply one of these solutions:
  • If you want the third stage of classification to be based upon a packet's DSCP value, delete the PCP map.
  • If you want the third stage of classification to be based upon a frame's PCP value, delete the DSCP map.
