Change Country Code of a WLC
Before you can change the country code of a WLC, you must disable the 802.11a and 802.11b network :
config 802.11a disable network
config 802.11b disable network
Now you can change the country code of the controller. In this case we change it from US to GB (United Kingdom)
config country GB
You will see the following message :
Changing country code could reset channel configuration.
If running in RFM One-Time mode, reassign channels after this command
Check customized APs for valid channel values after this command.
Are you sure you want to continue? (y/n) y
