Error: "Only dscp or pcp classification allowed not both"
Cause
You tried to configure an ingress map with both DSCP groups and PCP values.
You will trigger this error if you combine commands like these:
set policy qos ingress-map <ingress-map-name> dscp-group ...
set policy qos ingress-map <ingress-map-name> pcp ...Remedy
Decide whether you want the second stage of classification to be based upon the DSCP value of the packet or the PCP value of the frame. Then delete the redundant commands.
