Information About Marking

Marking is a method that you use to modify the QoS fields of the incoming and outgoing packets. The QoS
fields that you can mark are CoS in Layer 2, and IP precedence and Differentiated Service Code Point (DSCP)
in Layer 3. The QoS group and discard class are two labels local to the system that you can assign intermediate
marking values. You can use these two labels to determine the final values marked in a packet.
You can use marking commands in traffic classes that are referenced in a policy map. The marking features
that you can configure are listed in the table below.
