Getting started
The bulk of the configuration tasks required to setup aCentralized WLAN solution are performed on theWireless LAN Controller.
Lightweight Access Points are designed to be zero
touch and are not directly configured by theadministrator.
The very basic configuration tasks required on the WLCare done via CLI, while more complex tasks are
completed after the web interface is accessible.

WLC and Lightweight AP Configuration
These are the basic steps to getting the controller andAPs online:
Have a DHCP server present so that the APs canacquire a network address.
Note: Option 43 is used if the APs reside in a different subnet.
Configure the WLC for basic operation.
Configure the switch for the WLC.
Configure the switch for the APs.
Register the lightweight APs to the WLCs.

AP Registration to WLC
As soon as the controller is activated, it starts listeningfor access points on all connected ports.
As it detects access points, it records their MACaddresses in its database.
The Radio Resource Management (RRM) function thenautomatically configures the access points to starttransmitting and start allowing clients to connectthrough the Cisco WLAN Solution.
