3 Refer to the WMM table for the following information:
4 To modify the properties of WMM Adoption Settings, select a radio and click the Edit button (at the
bottom of the screen). For more information, see “Editing Access Point Adoption WMM Settings” on
page 211.
Editing Access Point Adoption WMM Settings
Use the Edit screen to modify a WMM profile's properties (AIFSN, Transmit Ops, Cw Min and CW
Max). Modifying these properties may be necessary as Access Categories are changed and transmit
intervals need adjustment to compensate for larger data packets and contention windows.Use
“Configuring WMM” on page 196 to configure downstream traffic parameters. WLAN WMM
configuration affects your upstream traffic parameters.
To edit the existing WMM settings:
AP Type
Displays whether the radio is an 802.11a radio or an 802.11bg radio.
This value is read-only and cannot be modified.
Access Category
Displays the Access Category currently in use. There are four categories:
Video, Voice, Best Effort and Background. Click the Edit button to change
the current Access Category. Ensure the Access Category reflects the
radios intended network traffic.
AIFSN
Displays the current
Arbitrary Inter-frame Space Number
(AIFSN). Higher-
priority traffic categories should have lower AIFSNs than lower-priority
traffic categories. This causes lower-priority traffic to wait longer before
trying to access the medium.
Transmit Ops
Displays the maximum duration a device can transmit after obtaining a
transmit opportunity. For higher-priority traffic categories, this value
should be set higher.
ECW Min
The ECW Min is combined with the ECW Max to define the Contention
Window. From this range, a random number is selected for the back off
mechanism. Lower values are used for higher priority traffic.
ECW Max
The ECW Max is combined with the ECW Min to make the Contention
Window. From this range, a random number is selected for the back off
mechanism. Lower values are used for higher priority traffic.
