Table 225: WMM Access Category to 802.1p Priority Mapping
In non-WMM, or hybrid environments where some clients are not WMM-capable, Alcatel-Lucent uses voice and
best effort to prioritize traffic from these clients.
Unscheduled Automatic Power Save Delivery (U-APSD) is a component of the IEEE 802.11e standard that
extends the battery life on voice over WLAN devices. When enabled, clients trigger the delivery of buffered
data from the AP by sending a data frame.
For the environments in which the wireless clients support WMM, you can enable both WMM and U-APSD in
the SSID profile.
Enabling WMM
You can use the WebUI or CLI to enable WMM for wireless clients.
In the WebUI
To enable WMM for wireless clients:
1. Navigate to the Configuration > Wireless > AP Configuration page.
2. Select either the AP Group or AP Specific tab. Click Edit for the AP group or AP name.
3. In the Profiles list, select Wireless LAN, then Virtual AP, then the applicable virtual AP profile. Select the
SSID profile.
4. In the Profile Details, select the Advanced tab.
5. Select the Wireless Multimedia (WMM) option. Or, select the Wireless Multimedia U-APSD (WMM-
UAPSD) Powersave option if you want to enable WMM in power save mode.
6. Click Apply.
In the CLI
To enable WMM for wireless clients:

Configuring WMM AC Mapping
The IEEE 802.11e standard defines the mapping between WMM ACs and Differentiated Services Code Point
(DSCP) tags. The WMM AC mapping commands allow you to customize the mapping between WMM ACs and
