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

-
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.

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

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

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

-
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.

-
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.
-
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.

-
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 ?

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

-
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.”
