Specifies the CoS value to cos-value.
The cos-value can range from 0 to 7.
This command is supported only for egress

policies.
Purpose
Displays the already configured policy maps and CoS values.
In Layer 3 topologies, each qosgroup must have a unique CoS
value. Use the show policy-map system command to view
CoS values that have been used and that are unavailable for
QoS groups.
Enters global configuration mode.
