Configuring WMM for Wireless Clients
You can configure WMM for wireless clients by using the UI or the CLI.
In the Instant UI
To configure the WMM for wireless clients:
1. Navigate to the WLAN wizard.
a. Click Networks > New or
b. Click Networks, and 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 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.
l Background WMM—Allocates 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.
4. Click Next and complete the configuration as required.
In the CLI
Configuring WMM for wireless clients:
(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
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.
