Channel planning 85
Interference threshold
Select the minimum percentage of interference reduction a proposed plan must achieve to be
applied. The default is 75 percent. You can select 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 reset the minimal channel interference threshold to 25 percent, the proposed
channel plan will be implemented and channels will be reassigned as needed.
Last proposed channels applied
If a channel plan was previously applied on the AP, this field shows the number of hours and
minutes that have passed since it was applied.
Current channel assignments
Use this section to view the list of all APs in the cluster by IP address. The display shows the
band on which each AP is broadcasting (a/b/g/n), the channel currently used by each AP,
and an option to lock an AP on its current radio channel so that it cannot be reassigned to
another.
IP address
The AP IP address.
Radio
The MAC address of the radio.
Band
The band on which the AP is broadcasting.
Channel
The radio channel on which this AP is broadcasting.
Proposed channel
The channel to which this AP will be reassigned when the current channel plan is applied. The
proposed channel and current channel can be different if any of the following have occurred:
• DFS is enabled and has marked the proposed channel out of service.
• The channel is locked because the Locked checkbox is selected.
• The proposed channel has not yet been applied (there is a small window of time between
the proposal and the application of the proposed channel).
