Configuring Standard QoS
To return to the default map, use the no mls qos policed-dscp global configuration command.
This example shows how to map DSCP 50 to 57 to a marked-down DSCP value of 0:
Switch(config)# mls qos map policed-dscp 50 51 52 53 54 55 56 57 to 0
Switch(config)# end
Switch# show mls qos maps policed-dscp
Policed-dscp map:
In this policed-DSCP map, the marked-down DSCP values are shown in the body of the matrix. The d1
Note
column specifies the most-significant digit of the original DSCP; the d2 row specifies the
least-significant digit of the original DSCP. The intersection of the d1 and d2 values provides the
marked-down value. For example, an original DSCP value of 53 corresponds to a marked-down DSCP
value of 0.

Configuring the DSCP-to-CoS Map

You use the DSCP-to-CoS map to generate a CoS value, which is used to select one of the four egress
queues.
