Configuring WMM U-APSD
To extend the battery life and enable power saving on WLAN clients, APs support
Unscheduled Automatic Power Save Delivery (U-APSD) for the clients that support WMM.
The U-APSD or the WMM Power Save feature is enabled by default on all SSIDs. When
configured, U-APSD enables a client station to retrieve the unicast QoS traffic buffered in the
AP by sending trigger frames. During the association or reassociation with the AP, the
station indicates the WMM Access Categories for which U-APSD is enabled. In the current
release, APs support U-APSD on all WMM ACs.
To disable U-APSD on an SSID:
(scalance)(config)# wlan ssid-profile <ssid_profile>
(scalance)(SSID Profile "<ssid_profile>")# wmm-uapsd-disable
(scalance)(SSID Profile "<ssid_profile>")# end
(scalance)# commit apply
To re-enable U-APSD on an SSID:
(scalance)(config)# wlan ssid-profile <ssid_profile>
(scalance)(SSID Profile "<ssid_profile>")# no wmm-uapsd-disable
(scalance)(SSID Profile "<ssid_profile>")# end
(scalance)# commit apply
