For example, to configure static CoS 7 for service profile sp1, use the 
following commands:

WX1200# set service-profile sp1 static-cos enable
success: change accepted.
WX1200# set service-profile sp1 cos 7
success: change accepted.

To change CoS mappings, use the following commands:

set qos dscp-to-cos-map dscp-range cos level
set qos cos-to-dscp-map level dscp dscp-value

The first command changes the mapping of ingress DSCP values to the 
internal QoS table when marking packets. The second command changes 
the mappings of the internal QoS values to DSCP value when tagging 
outbound packets. 

The following command changes the mapping of DSCP value 45 from 
CoS value 5 to CoS value 7. (The change affects classification but does 
not affect marking.)

WX1200# set qos dscp-to-cos-map 45 cos 7
success: change accepted.

The following command changes the mapping of CoS value 6 from DSCP 
value 48 to DSCP value 55. (The change affects marking but does not 
affect classification.)

WX4400# set qos cos-to-dscp-map 6 dscp 55
success: change accepted.

To configure MSS to classify the QoS level of IP packets based on their 
DSCP value, instead of their 802.11 priority, use the following command:

set service-profile name use-client-dscp {enable | disable}

If this command is enabled in the service profile, the 802.11 QoS level is 
ignored, and MSS classifies QoS level of IP packets based on their DSCP value.

The following command enables mapping the QoS level of IP packets 
based on their DSCP value for service profile sp1:

WX# set service-profile sp1 use-client-dscp enable
success: change accepted.
