RF Channel Assignment
Channel Assignment 
Method
The controller’s dynamic channel assignment mode.
Options: Automatic, On Demand, or Off
Default: Automatic
Channel 
Assignment 
Method
Description
Automatic
Causes the controller to periodically evaluate and, if 
necessary, update the channel assignment for all joined 
access points.
On  Demand
Causes the controller to periodically evaluate the channel 
assignment for all joined access points. However, the 
controller reassigns channels, if necessary, only when 
you click Invoke Channel Update Now.
Note
The controller does not evaluate and update the 
channel immediately after you click Invoke 
Channel Update Now. It waits for the next 
interval (default is 600 seconds).
Off
Prevents the controller from evaluating and, if necessary, 
updating the channel assignment for joined access 
points. 
Note
For optimal performance, Cisco recommends that you use the 
Automatic setting. Refer to the 
 for instructions if you ever need to disable the 
controller’s dynamic settings.
Avoid Foreign AP 
Interference
Causes the controller’s RRM algorithms to consider 802.11 traffic from 
foreign access points (those not included in your wireless network) 
when assigning channels to lightweight access points. For example, 
RRM may adjust the channel assignment to have access points avoid 
channels close to foreign access points.
Options: Enabled or Disabled
Default: Enabled
