6 - 52 WiNG 5.5 Access Point System Reference Guide
6. Set the following Video Access settings for the WLAN’s QoS policy:
7. Set the following Voice Access settings for the WLAN’s QoS policy:
Non-Unicast
Classification
Use this drop-down menu to define how traffic matching multicast masks is classified
relative to prioritization on the radio. Options include Video, Voice, Normal, Low and
Default. The default setting is Default.
Enable Voice
Prioritization
Select this option if Voice traffic is prioritized on the WLAN. This gives priority to voice
and voice management packets and is supported only on certain legacy Motorola
Solutions VOIP phones. This feature is disabled by default.
Enable SVP Prioritization Enabling Spectralink Voice Prioritization (SVP) allows the access point to identify and
prioritize traffic from Spectralink/Polycomm phones. This gives priority to voice, with voice
management packets supported only on certain legacy Motorola VOIP phones. If the
Wireless Client Classification is WMM, non-WMM devices recognized as voice devices
have all their traffic transmitted at voice priority. Devices are classified as voice, when
they emit SIP, SCCP or H323 traffic. Thus, selecting this option has no effect on devices
supporting WMM. This feature is disabled by default.
Enable WMM Power
Save
Enables support for the WMM based power-save mechanism, also known as Unscheduled
Automatic Power Save Delivery (U-APSD). This is primarily used by WMM capable voice
devices. This feature is enabled by default.
Enable QBSS Load IE Select this option to enable support for WMM QBSS load information element in beacons
and probe response packets. This feature is enabled by default.
Configure Non WMM
Client Traffic
Use the drop-down menu to specify how non-WMM client traffic is classified on this
access point WLAN if the Wireless Client Classification is set to WMM. Options include
Video, Voice, Normal and Low. The default setting is Normal.
Transmit Ops Use the slider to set the maximum duration a device can transmit after obtaining a
transmit opportunity. The default value is 94.
AIFSN Set the current Arbitrary Inter-frame Space Number (AIFSN) from 2 - 15. Higher-priority
video categories should have lower AIFSNs than lower-priority traffic categories. This will
cause lower-priority traffic to wait longer before attempting access. The default value is 2.
ECW Min ECW Min is combined with ECW Max to create the contention value in the form of a
numerical range. From this range, a random number is selected for the back off
mechanism. Lower values are used for higher priority traffic (like video). The available
range is from 0-15. The default value is 3.
ECW Max ECW Max is combined with ECW Min to create the contention value in the form of a
numerical range. From this range, a random number is selected for the back off
mechanism. Lower values are used for higher priority traffic (like video). The available
range is from 0-15. The default value is 4.
Transmit Ops Use the slider to set the maximum duration a device can transmit after obtaining a
transmit opportunity. The default value is 47.
AIFSN Set the current Arbitrary Inter-frame Space Number (AIFSN) from 2 - 15. Higher-priority
voice categories should have lower AIFSNs than lower-priority traffic categories. This will
cause lower-priority traffic to wait longer before attempting access. The default value is 2.
