Article ID: KB34178 KB Last Updated: 16 May 2019Version: 1.0
Summary:

This article summarizes how to manually change AP channels that are already selected to be auto-tune channels. The article will follow the below pattern to demonstrate the steps:

  • Enable auto-tune channel assignment.

  • Apply the changes to the AP.

  • Disable the auto-tune channel.

  • Manually select the AP's channel.

 

Solution:

When customers want to use manual channel selection rather than auto-tune channel selection (Adaptive Channel Planner) by using the Wireless Controller's Command Line Interface (CLI), the following steps are required:

  1. Go to the WLC CLI and check the AP status to determine the current channel selection by using the #show ap status command.

  1. Create a radio-profile to enable the auto-tune channel by using the #set ap apnum radio radionum radio-profile radio-profile name command. Save the changes.

  1. Check the AP status again by using #show ap status.

  1. Start the auto-tune deployment to enable the auto-tune channel selection by using #run auto-tune deployment band 11bg.

  1. Check for the attributes by using #show auto-tune attributes.

  1. Check the AP status by using #show ap status.

Note: The AP 9997 radio 1 channel has been changed from “channel 1” to “channel 11” after the auto-tune channel was enabled.

  1. Now disable the auto-tune channel by using # set auto-tune channel band 11bg mode disable and check the AP status again by using #show ap status.

 

Note: Even after disabling the auto-tune channel selection, the channels are the same for the respective APs, because unless the channels are changed manually, they will continue to work with the previously selected channels.

  1. Verify that the auto-tune channel is disabled by using #run auto-tune deployment band 11bg.

Note: If the auto-tune channel assignment is disabled, the above command will display “Auto-tune disabled” error message.

  1. Now you can manually select the channel number that you want to assign to the radio from the available channel list.

To view the channel list, use the following command: set ap apnum radio radionum channel ?

  1. Select a channel manually and save the changes by using #set ap 9997 radio 1 channel 1 and #sa c, respectively.

  1. Verify the changes and check the AP status again by using #show ap status.

 

Note: The changes are successful because the “ap 9997 radio1 channel” has been changed successfully to “channel 1” from “channel 11.”
