Quality of Service
The quality of service (QoS) settings provide you with the ability to configure transmission
queues for optimized throughput and better performance when handling differentiated wireless
traffic, such as Voice-over-IP (VoIP), other types of audio, video, streaming media, and
traditional IP data.
queues for optimized throughput and better performance when handling differentiated wireless
traffic, such as Voice-over-IP (VoIP), other types of audio, video, streaming media, and
traditional IP data.
To configure QoS on the AP, you set parameters on the transmission queues for different types
of wireless traffic and specify minimum and maximum wait times (through contention
windows) for transmission.

Station EDCA parameters affect traffic flowing from the client station to the WAP device.
In normal use, the default values for the WAP device and station EDCA should not need to be
changed. Changing these values affects the QoS provided.

To configure WAP device and Station EDCA parameters:
STEP 1
Select Wireless > QoS in the navigation pane.Select the radio interface on which to configure

STEP 2
Select an option from the EDCA Template list:
•
WFA Defaults—Populates the WAP device and Station EDCA parameters with WiFi
Alliance default values, which are best for general, mixed traffic.

•
Custom—Enables you to choose custom EDCA parameters.
These four queues are defined for different types of data transmitted from WAP-to-station. If
you choose a Custom template, the parameters that define the queues are configurable;
otherwise, they are set to predefined values appropriate to your selection. The four queues are:
