Wireless Controller
effectively specifying minimum and maximum wait times (through Contention
Windows) for transmission. The settings described here apply to data transmission
behavior on the access point only, not to that of the client stations. AP Enhanced
Distributed Channel Access (EDCA) Parameters affect traffic flowing from the
access point to the client station. Station Enhanced Distributed Channel Access
(EDCA) Parameters affect traffic flowing from the client station to the access
point. You can specify custom QoS settings, or you can select a template that
configures the AP profile with pre -defined settings that are optimized for data
traffic or voice traffic.
Radio Mode: From this field, you can select the radio for which you want to
configure QoS settings. Settings for each radio are configured separately. By
default, Radio 1 operates in IEEE 802.11a/n mode, and Radio 2 operates in
IEEE 802.11b/g/n mode. If you change the mode, the labels for the radios
change accordingly. Changes to the settings apply only to the selected radio.
The DWL--3600AP is a single- radio AP. Any settings you configure for
Radio 1 (802.11a/n) are not applied to the DWL --3600AP. If the selected
Hardware Type ID for the AP profile is DWL--3600AP, the radio selectors
are not available.
Template: Select the QoS template to apply to the AP profile. If you select
Custom, you can change the AP and station parameters. If you select Voice
or Factory Defaults, the controller will use the pre-defined settings for the
template you select.
AP EDCA Parameters:
Queue: Queues are defined for different types of data transmitted from AP -
to-station:



Data 0 (Voice): High priority queue, minimum delay. Time -sensitive
data such as VoIP and streaming media are automatically sent to this
queue.
Data 1 (Video): High priority queue, minimum delay. Time -sensitive
video data is automatically sent to this queue.
Data 2 (best effort): Medium priority queue, medium throughput and
delay. Most traditional IP data is sent to this queue.
