qos map dscp-traffic-class

map on the ingress interface. You can configure an interface with either a DSCP-to-Traffic-Class
map or a CoS-to-Traffic-Class map.

Description
Use this command to create a QoS DSCP-Traffic-Class map. Use this command to remap the
incoming DSCP values of the ingress packet to a Traffic Class.
Usage Guidelines
Enter qos dscp-traffic-class name while in configuration mode for a specific interface to apply the
QoS DSCP-Traffic-Class map to that interface. When you enter qos map dscp-traffic-class, the
system is placed in dscp-traffic-class mode for the configured map. At this point, you can map
ingress DSCP values to traffic class values using the mark command.
Enter no qos dscp-traffic-class name while in the interface mode to remove the map from that
interface.
Enter no map dscp-mutation name to remove the map while in global configuration mode.
Examples
To create a QoS DSCP-Traffic-Class map and place system into dscp-traffic-class mode:
switch(config)# qos map dscp-traffic-class test
switch(dscp-traffic-class-test)#
To map ingress DSCP values to a traffic class while in dscp-traffic-class mode:
switch(dscp-traffic-class-test)# mark 1,3,5,7 to 3
To map multiple ingress DSCP values to traffic classes while in dscp-traffic-class mode:
switch(dscp-traffic-class-test)# mark 1,3,5,7 to 3
switch(dscp-traffic-class-test)# mark 11,13,15,17 to 5
switch(dscp-traffic-class-test)# mark 12,14,16,18 to 6
switch(dscp-traffic-class-test)# mark 2,4,6,8 to 7
To remove a QoS DSCP-Traffic-Class map while in global configuration mode:
switch(config)# no qos map dscp-traffic-class test
