How does a LAP initially connect to a WLC?

A Lightweight Access Point (LAP) initially connects to a Wireless LAN Controller (WLC) by broadcasting a discovery message. This process is critical as it allows the LAP to discover the WLC in the network environment.

When powered on, the LAP sends out a Discovery Protocol message, commonly known as a broadcast message, to locate the WLCs within its broadcast domain. The discovery process is essential because it enables the LAP to identify the WLC's presence and obtain necessary configuration information for further communication. This method is particularly effective in dynamic environments where the network may change frequently, allowing access points to locate and connect to the appropriate controller without manual intervention.

In contrast, manually entering the WLC's IP address is a more static approach that does not utilize the dynamic capabilities of LAPs, making the discovery message method more suitable for environments that require flexibility and ease of deployment. While connecting through a physical cable can establish a link, it is not the method utilized for initial WLC discovery. Similarly, scanning for available networks does not address the specific requirement of locating a WLC for control and configuration purposes.
