Nortel WLAN—Security Switch 2300 Series Configuration Guide

The Auto-RF feature dynamically assigns channel and power settings to AP radios, and adjusts those settings when 
needed. Auto-RF can perform the following tasks:

•

Assign initial channel and power settings when an AP radio is started. 

•

Periodically assess the RF environment and change the channel or power settings if needed.

By default, Auto-RF is enabled for channel configuration and disabled for power configuration.  

The following process is used to assign the channel and power to an AP radio when it is first enabled:

•

If Auto-RF is disabled for both channel and power assignment, the radio uses the channel and power settings in the 
radio profile that manages the radio. After this, the channel and power do not change unless you change the settings 
in the radio profile, or enable Auto-RF.

•

If Auto-RF is enabled for channel and power assignment, the radio performs an RF scan and reports the results to 
the WSS that is managing the AP the radio is on. The scan results include third-party access points. Based on the 
scan results, WSS Software sets the channel and power on the radio. WSS Software always selects channel and 
power settings that are valid for the country of operation. 

●

Initial channel assignment—WSS Software selects a channel at random from the set of valid 
channels for the radio type and country code. After this, each subsequent time the radio or Auto-RF 
is restarted, a different channel is selected to ensure even distribution among the channels.

During radio operation, WSS Software periodically reevaluates the channel and changes it if needed. 
(See 

Auto-RF of channels on 802.11a radios uses only the bottom eight channels in the 

band (36, 40, 44, 48, 52, 56, 60, and 64). To use a higher channel number, you must 
disable Auto-RF of channels on the radio profile the radio is in, and statically configure the 
channel.
