Default CoS-to-DSCP Map
You use the CoS-to-DSCP map to map CoS values in incoming packets to a DSCP value that QoS uses
internally to represent the priority of the traffic. The following table shows the default CoS-to-DSCP map. If
these values are not appropriate for your network, you need to modify them.
