The WLC management interface is used for L2 communication between WLC and APs.
A WLC has one or more AP manager interface for L3 communication between WLC and LAP after AP discovers the controller.
Sequential events for LAP to register with WLC:
1. The LAP issues a DHCP discovery reequest to get an IP address unless it has previously had a static IP address.
2. The LAP sends LWAPP(Light Weight Access Point Protocol) dicovery request to WLC.
3. Any WLC the receives LWAPP discovery request responds with an LWAPP discovery response message.
4. From multiple discovery responses LAP chooses the WLC to join(The WLC with least connection is preferred).
5. The LAP then sends an LWAPP join reuqest to the WLC & expects a LWAPP join response.
6. The WLC validates the LAP & then sends an LWAPP join response to the LAP.
7. The LAP validates the WLC which completes the discovery & join process. The LWAPP join process includes mutual authentication and encryption key derived.
8. The LAP registers with the controller.
Hope I could make it easier as it is. :)
