Quality of Service Commands

Use Quality of Service (QoS) commands to configure packet prioritization in MSS. Packet prioritization ensures that DWS-1008 switches and DWL-8220AP access points give preferential treatment to high- priority traffic such as voice and video.

This chapter presents QoS commands alphabetically. Use the following table to locate commands in this chapter based on their use.

clear qos

Resets the switch’s mapping of Differentiated Services Code Point (DSCP) values to internal QoS values.

The switch’s internal QoS map ensures that prioritized traffic remains prioritized while transiting through the DWS-1008 switch. A switch uses the QoS map to do the following:

•Classify inbound packets by mapping their DSCP values to one of eight internal QoS values

•Classify outbound packets by marking their DSCP values based on the switch’s internal QoS values

Syntax: clear qos [cos-to-dscp-map [from-qos] dscp-to-cos-map [from-dscp]]

cos-to-dscp-mapResets the mapping between the specified internal QoS value and the

[from-qos]	DSCP values with which MSS marks outbound packets. QoS values are
	from 0 to 7.

dscp-to-cos-mapResets the mapping between the specified range of DSCP values and

[from-dscp] internal QoS value with which MSS classifies inbound packets.
