Configuring The Dscp-To-Cos Map - Cisco WS-CBS3032-DEL Software Configuration Manual

Configuring Standard QoS
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.

DSCP Value
0–7
8–15
16–23
24–31
32–39
40–47
48–55
56–63
If these values are not appropriate for your network, you need to modify them.
