Configuring DSCP Maps

These sections contain this configuration information:

Configuring the CoS-to-DSCP Map, page 36-60

(optional)

Configuring the IP-Precedence-to-DSCP Map, page 36-61

(optional)

Configuring the Policed-DSCP Map, page 36-62

(optional, unless the null settings in the map are

not appropriate)

(optional)

(optional, unless the null settings in the

map are not appropriate)

All the maps, except the DSCP-to-DSCP-mutation map, are globally defined and are applied to all ports.

Configuring the 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.

Table 36-12

shows the default CoS-to-DSCP map.

If these values are not appropriate for your network, you need to modify them.
