4.7.4.1 Editing WMM Settings
Use the Edit screen to modify a WMM profile's properties (AIFSN, Tx Op, Cw Min and CW Max). Modifying
these properties may be necessary as Access Categories are changed and transmit intervals need to be
adjusted to compensate for larger data packets and contention windows.
To edit existing WMM Settings:
1. Select
Network > Access Port Radios
from the main menu tree.
2. Click the
WMM
tab.
3. Select a radio from the table and click the
Edit
button to launch a screen displaying the WMM
configuration for that radio.
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 radio’s intended network traffic.
AIFSN
Displays the current Arbitrary Inter-frame Space Number. Higher-priority traffic categories
should have lower AIFSNs than lower-priority traffic categories. This will 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.
CW Min
Displays the CW Max 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.
CW Max
Displays the CW 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.
