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.
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 VOIP phones
manufactured by us. This feature is disabled by default.
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 VOIP phones manufactured by us.
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.
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.
Select this option to enable support for WMM QBSS load information element in beacons
and probe response packets. This feature is enabled by default.
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.
Video Access settings for the WLAN's QoS policy:
Use the slider to set the maximum duration a device can transmit after obtaining a
transmit opportunity. The default value is 94.
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 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 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.
Voice Access settings for the WLAN's QoS policy:
Use the slider to set the maximum duration a device can transmit after obtaining a
transmit opportunity. The default value is 47.
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.
