4.5.3.1 Editing WMM Settings
WLAN WMM configuration affects your upstream traffic parameters. Use Configuring WMM on page 4-108 to configure
downstream traffic parameters. Use the WMM Edit screen to modify existing Access Category settings for the WLAN
selected within the WMM screen. This could be necessary in instances when data traffic has changed and high-priority
traffic (video and voice) must be accounted for by modifying AIFSN Transmit Ops and CW values.
To edit existing WMM Settings:
1. Select Network Setup > WLAN Setup from the main menu tree.
2. Click the WMM tab.
3. Select a Access Category from the table and click the Edit button to launch a dialog with WMM configuration for that
radio.
4. Refer to the Edit WMM screen for the following information:
SSID Displays the Service Set ID (SSID) associated with the selected WMM index. This SSID is
read-only and cannot be modified within this screen.
Access Category Displays the Access Category for the intended radio traffic. The Access Categories are the
different WLAN-WMM options available to the radio.
The four Access Category types are:
• Background - Optimized for background traffic.
• Best-effort - Optimized for best effort traffic.
• Video - Optimized for video traffic. Video traffic receives priority.
• Voice - Optimized for voice traffic. Voice traffic receives priority.
AIFSN Defines the current Arbitrary Inter-frame Space Number (AIFSN). Higher-priority traffic
categories should have lower AIFSNs than lower-priority traffic categories. This will cause
lower-priority traffic to wait longer before trying to access the medium.
Transmit Ops Defines 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.
