Configuring Advanced Settings

The advanced settings allow you to customize and schedule the channel plan for
the cluster. If you use Channel Management as provided (without updating
Advanced Settings), channels are automatically fine-tuned once every hour if
interference can be reduced by 25 percent or more. Channels are reassigned
even if the network is busy. The appropriate channel sets will be used (b/g for
access points using IEEE 802. 1 1b/g and a for access points using IEEE 802. 1 1a).
The default settings are designed to satisfy most scenarios where you would
need to implement channel management.
Use Advanced Settings to modify the interference reduction potential that triggers
channel re-assignment, change the schedule for automatic updates, and
reconfigure the channel set used for assignments. If there are no fields showing in
the Advanced section, click the toggle button to display the settings that modify
timing and details of the channel planning algorithm.

Description
Specify the minimum percentage of interference
reduction a proposed plan must achieve in order to
be applied. The default is 75 percent.
Use the drop-down menu to choose percentages
ranging from 5 percent to 75 percent.
This setting lets you set a gating factor for channel re-
assignment so that the network is not continually
disrupted for minimal gains in efficiency.
For example, if channel interference must be reduced
by 75 percent and the proposed channel
assignments will only reduce interference by 30
percent, then channels will not be reassigned.
However; if you re-set the minimal channel
interference benefit to 25 percent and click Apply,
the proposed channel plan will be implemented and
channels reassigned as needed.
