Field/Button Description
Wireless QoS From the Wireless QoS list, do the following:
Legacy — Select if your service will support legacy devices.
WMM — Select to enable the AP to accept WMM client
associations, and classify and prioritize the downlink traffic for all
WMM clients. Note that WMM clients will also classify and
prioritize the uplink traffic. WMM is part of the 802.11e standard for
QoS. If selected, the Turbo Voice and Enable U-APSD options
are displayed.
802.11e — Select to enable the AP to accept WMM client
associations, and classify and prioritize the downlink traffic for all
802.11e clients. The 802.11e clients will also classify and prioritize
the uplink traffic. If selected, the Turbo Voice and the Enable U-
APSD options are displayed:
Turbo Voice — Select to enable all downlink traffic that is
classified to the Voice (VO) AC and belongs to that VNS to be
transmitted by the AP via a queue called Turbo Voice (TVO)
instead of the normal Voice (VO) queue. When Turbo Voice is
enabled together with WMM or 802.11e, the WMM and/or 802.11e
clients in that VNS are instructed by the AP to transmit all traffic
classified to VO AC with special contention parameters tailored to
maximize voice performance and capacity.
Enable U-APSD — Select to enable the Unscheduled Automatic
Power Save Delivery (U-APSD) feature. This feature can be used
by mobile devices to efficiently sustain one or more real-time
streams while being in power-save mode. This feature works in
conjunction with WMM and/or 802.11e, and it is automatically
disabled if both WMM and 802.11e are disabled.
Admission Control From the Admission Control list, do the following:
Use Global Admission Control for Voice (VO) - Select to
enable admission control for Voice. With admission control, clients
are forced to request admission to use the high priority access
categories in both downlink and uplink direction. Admission
control protects admitted traffic against new bandwidth demands.
For more information, see VNS Global Settings.
Use Global Admission Control for Video (VI) - This feature is
only available If admission control is enabled for Voice. With
admission control, clients are forced to request admission to use
the high priority access categories in both downlink and uplink
direction. Admission control protects admitted traffic against new
bandwidth demands.Select to provide distinct thresholds for VI
(video). For more information, see VNS Global Settings.
