Parameter	Description
RF Channel Assignment
Channel Assignment	The controller’s dynamic channel assignment mode.
Method	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 “Disabling Dynamic Channel
	and Power Assignment Globally for a Controller” section on
	page 9-27for instructions if you ever need to disable the
	controller’s dynamic settings.
Avoid Foreign AP	Causes the controller’s RRM algorithms to consider 802.11 traffic from
Interference	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
