-
Enter global configuration mode.
device# configure terminal
-
Create and name a QoS DSCP-to-traffic class map.
device(config)# qos map dscp-traffic-class dscpTcMap
-
Define the QoS DSCP-to-traffic class values.
device(config-dscp-traffic-class-dscpTcMap)# map dscp 10 to traffic-class 3
device(config-dscp-traffic-class-dscpTcMap)# map dscp 40 to traffic-class 4
device(config-dscp-traffic-class-dscpTcMap)# map dscp 45 to traffic-class 5
device(config-dscp-traffic-class-dscpTcMap)# map dscp 52 to traffic-class 3
The default value is used for those DSCP that are not explicitly defined.
-
Return to privileged exec mode.
device(config-dscp-traffic-class-dscpTcMap)# end
-
Verify the configuration.
device# show qos maps dscp-traffic-class
