Description
Use this field to set and display the folder with which the profile is
associated. The drop-down menu displays all folders available for
association with the profile. Folders provide a way to organize the visibility
of device parameters that is separate from the configuration groups of
devices. Using folders, you can view basic statistics about device, and
define which users have visibility to which device parameters.
Name of the EADC AP profile.
WMM is an extension to the Carrier Sense Multiple Access with Collision
Avoidance (CSMA/CA) protocol's Distributed Coordination Function (DCF).
The collision resolution algorithm responsible for traffic prioritization
depends on the following configurable parameters for each AC:
arbitrary inter-frame space number (AIFSN)
minimum and maximum contention window (CW) size
For each AC, the backoff time is the sum of the AIFSN and a random value
between 0 and the CW value. The AC with the lowest backoff time is
granted the opportunity to transmit (TXOP). Frames with the highest
priority AC are more likely to get TXOP as they tend to have the lowest
backoff times (a result of having smaller AIFSN and CW parameter values).
The value of the CW varies through time as the CW doubles after each
collision up to the maximum CW. The CW is reset to the minimum value
after successful transmission.
In addition, you can configure the TXOP duration for each AC.
