3. Specify a percentage value for the following WMM access categories in the
corresponding Share text box. You can allocate a higher bandwidth for voice and video
traffic than that for other types of traffic based on the network profile.
– Background WMM—Allocates bandwidth for background traffic such as file downloads
– Best effort WMM—Allocates bandwidth or best effort traffic such as traffic from legacy
– Video WMM—Allocates bandwidth for video traffic generated from video streaming.
– Voice WMM—Allocates bandwidth for voice traffic generated from the incoming and

Mapping WMM ACs and DSCP Tags
The IEEE 802.11e standard defines the mapping between WMM ACs and Differentiated
Services Code Point (DSCP) tags. You can customize the mapping values between WMM
ACs and DSCP tags to prioritize various traffic types and apply these changes to a WMM-
enabled SSID profile.
DSCP classifies packets based on network policies and rules. The following table shows the
default WMM AC to DSCP mappings and the recommended WMM AC to DSCP mappings.
