The static information configured with the CLI commands are used by the access point to connect with a controller. After connecting with the controller, the controller reconfigures the access point with new controller settings, but the static IP addresses for the access point and the default gateway are not changed.
Configuring Controller Information
To manually configure controller information on a new (out-of -the-box) access point using the access point CLI interface, you can use these EXEC mode CLI commands:
AP# lwapp ap ip address
AP# lwapp ip default-gateway IP-address
AP# lwapp controller ip address IP-address
AP# lwapp ap hostname name
Where name is the access point name on the controller.
