5. Set the following Voice Access settings for the WLAN’s QoS policy:
6. Set the following Normal (Best Effort) Access settings for the WLAN’s QoS policy:
7. Set the following Low (Background) Access settings for the WLAN’s QoS policy:
8. Set the following Other Settings for the WLAN’s QoS policy:
9. Select OK when completed to update this WLAN’s QoS settings. Select Reset to revert the
screen back to its last saved configuration.
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.
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. The available range is from 0-15. The default value is 2.
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. The available range is from 0-15. The default value is 3.
Transmit Ops Use the slider to set the maximum duration a device can transmit after obtaining a transmit
opportunity. The default value is 0.
AIFSN 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.
ECW Min 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.
ECW Max The ECW Max is combined with the 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. Higher
values are used for lower priority traffic. The available range is from 0-15. The default value is 10.
Transmit Ops 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.
AIFSN 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.
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. Higher values
are used for lower priority traffic. The available range is from 0-15. The default value is 4.
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. Higher values
are used for lower priority traffic. The available range is from 0-15. The default value is 10.
Trust IP DSCP Select this option to trust IP DSCP values for WLANs. This feature is enabled by default.
Trust 802.11 WMM QoS Select this option to trust 802.11 WMM QoS values for WLANs.This feature is enabled by default.
