Configuring WMM for Wireless Clients
You can configure WMM for wireless clients by using the UI or CLI.
In the Instant UI
1. Navigate to the WLAN wizard (click Network>New or Network> Select the WLAN SSID>edit).
2. Click Show advanced options under WLAN Settings.
3. Specify a percentage value for the following WMM access categories in the corresponding Share field. You
can allocate a higher bandwidth for voice and video traffic than other types of traffic based on the network
profile.
l Background WMMAllocates bandwidth for background traffic such as file downloads or print jobs.
l Best effort WMM —Allocates bandwidth or best effort traffic such as traffic from legacy devices or
traffic from applications or devices that do not support QoS.
l Video WMM—Allocates bandwidth for video traffic generated from video streaming.
l Voice WMM—Allocates bandwidth for voice traffic generated from the incoming and outgoing voice
communication.
In a non-WMM or hybrid environment, where some clients are not WMM-capable, you can allocate higher
values for Best effort WMM and Voice WMM to allocate a higher bandwidth to clients transmitting best
effort and voice traffic.
4. Click Next and complete the configuration as required.
In the CLI
(Instant AP)(config)# wlan ssid-profile <name>
(Instant AP)(SSID Profile <name>)# wmm-background-share <share>
(Instant AP)(SSID Profile <name>)# wmm-best-effort-share <share>
(Instant AP)(SSID Profile <name>)# wmm-video-share <share>
(Instant AP)(SSID Profile <name>)# wmm-voice-share <share>
(Instant AP)(SSID Profile <name>)# end
(Instant AP)# commit apply
Configuring WMM-DSCP Mapping
The IEEE 802.11e standard defines the mapping between WMM ACs and Differentiated Services Codepoint
(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.
