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. The available range is from
0-15. The default value is 2.
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. The available range is from
0-15. The default value is 3.
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 0.
Set the current Arbitrary Inter-frame Space Number (AIFSN) from 2 - 15. The default value
is 3. Lower priority traffic categories should have higher AIFSNs than higher priority traffic
categories. This will cause lower priority traffic to wait longer before attempting access.
The ECW Min is combined with the 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. Higher values are used for lower priority traffic. The available range is from
0-15. The default value is 4.

settings for the WLAN's QoS policy:
Use the slider to set the maximum duration a device can transmit after obtaining a
transmit opportunity. For higher-priority traffic categories, this value should be set to a low
number. The default value is 0.
Set the current AIFSN from 2 - 15. The default value is 7. Lower priority traffic categories
should have higher AIFSNs than higher priority traffic categories. This will cause lower
priority traffic to wait longer before attempting access.

for the WLAN's QoS policy:
Select this option to trust IP DSCP values for WLANs. This feature is enabled by default.
Select this option to trust 802.11 WMM QoS values for WLANs.This feature is enabled by
default.
