Use the priority-map command to configure Differentiated Service Code Point (DSCP) classification by mapping Service Class user priority levels to DSCP codepoints. The priority-map command is accessible from the wlan:<WLAN-service-name>:qos-policy context of the CLI.
After you run the priority-map command, run the apply command to implement the changes.
| dscp 0-64 | Specifies a DSCP codepoint value. | 
| user-priority 0-7 | Specifies the Service Class value to be assigned to a DSCP codepoint. | 
| qos-map0|1 | Configure DSCP markings to pre-defined QoS service classes. This parameter is used when only a subset of DSCP to UP mappings need to be advertised to the client. Use this parameter for WLAN hotspots. Hotspot type must be Enabled. | 
The following example assigns a Service class of 7 to DSCP codepoint 24:
EWC.extremenetworks.com:wlans:CNL-7-CP:qos-policy# priority-map dscp 24 user-priority 7 qos-map 1
EWC.extremenetworks.com:wlans:CNL-7-CP:qos-policy# apply
EWC.extremenetworks.com:wlans:CNL-7-CP:qos-policy# show priority-map
