7. Set the following Low (Background) Access settings for the radio QoS policy:
8. Select OK when completed to update the radio QoS settings for this policy. Select Reset to
revert the WMM screen back to its last saved configuration.
9. 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 controller or service platform managed Access Point before they can transmit or receive
data.
The name of the Radio QoS policy for which the admission control settings apply displays
in the banner of the QoS Policy screen.

10. Select the Firewall detection traffic Enable (e.g, SIP) check box to apply Radio QoS settings to
traffic detected Firewall. This feature is enabled by default.
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 between 1-15. 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 default value is 7.
ECW Min The ECW Min is combined with the 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 The ECW Max is combined with the 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.
