Network Setup 4-69
4.5.3.1 Editing WMM Settings
WLAN WMM configuration affects your upstream traffic parameters. Use Configuring WMM on page 4-111
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.
