6 - 66 WiNG 5.6 Access Point System Reference Guide
9. Set the following Low (Background) Access settings for the radio QoS policy:
10. Select OK when completed to update the radio QoS settings for this policy. Select Reset to revert back to last saved
configuration.
11. Select the Admission Control tab to configure an admission control configuration for selected radio QoS policy. Admission
control requires clients send their traffic specifications (TSPEC) to a managed access point before they can transmit or
receive data within the access point managed network.
The name of the radio QoS policy, for which the admission control settings apply, displays in the banner of the QoS Policy
screen.
ECW Min ECW Min is combined with ECW Max to create a 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 a 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. 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 1- 15. Higher-priority traffic 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 7.
ECW Min ECW Min is combined with ECW Max to create a 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 (like low). The available range
is from 0-15. The default value is 4.
ECW Max ECW Max is combined with ECW Min to create a 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 10.
