344CHAPTER 16: CONFIGURING QUALITY OF SERVICE

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.

Changing CoS Mappings

To change CoS mappings, use the following commands:

set qos dscp-to-cos-map dscp-rangecos 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.

Using the Client’s

DSCP Value to

Classify QoS Level

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.
