7 149 Clustering Multiple Access Points Configuring and Viewing Channel Management Settings 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 802.11b/g and a for access points using IEEE 802.11a). 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. Table 40 Advanced Channel Management Settings Field Description Change channels if Specify the minimum percentage of interference interference is reduced by reduction a proposed plan must achieve in order to at least 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 reassignment 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.
