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)
•
Configuring the DSCP-to-CoS Map, page 36-63
(optional)
•
Configuring the DSCP-to-DSCP-Mutation Map, page 36-64
(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.
