This value specifies (in milliseconds) the maximum burst length allowed for packet
bursts on the wireless network. A packet burst is a collection of multiple frames
transmitted without header information. The decreased overhead results in higher
throughput and better performance.

Wi-Fi MultiMedia (WMM)—Select Enable to enable Wi-Fi MultiMedia (WMM)
extensions. This field is enabled by default. With WMM enabled, QoS prioritization and
coordination of wireless medium access is on. With WMM enabled, QoS settings on the
WAP device control downstream traffic flowing from the WAP device to client station
(AP EDCA parameters) and the upstream traffic flowing from the station to the AP
(station EDCA parameters).

Disabling WMM deactivates QoS control of station EDCA parameters on upstream
traffic flowing from the station to the WAP device. With WMM disabled, you can still
set some parameters on the downstream traffic flowing from the WAP device to the
client station (AP EDCA parameters).

•
TXOP Limit (Station only)—The TXOP Limit is a station EDCA parameter and only
applies to traffic flowing from the client station to the WAP device. The Transmission
Opportunity (TXOP) is an interval of time, in milliseconds, when a WME client station
has the right to initiate transmissions onto the wireless medium (WM) towards the WAP
device. The TXOP Limit maximum value is 65535.

Configure the following additional settings:
•
No Acknowledgement—Select Enable to specify that the WAP device should not
acknowledge frames with QosNoAck as the service class value.

Unscheduled Automatic Power Save Delivery—Select Enable to enable APSD, which
is a power management method. APSD is recommended if VoIP phones access the
network through the WAP device.

STEP 5
Click Save. The changes are saved to the Startup Configuration.
!
CAUTION
After new settings are saved, the corresponding processes may be stopped and restarted. When
this happens, the WAP device may lose connectivity. We recommend that you change WAP
device settings when a loss of connectivity will least affect your wireless clients.
