What is a wireless LAN controller (WLC)?
A. Wireless networks have become a necessity today. Many corporate environments require deployment of wireless networks on a large scale. Cisco has come up with the concept of the Cisco Unified Wireless Network (CUWN) solution, which helps make it easier to manage such large scale deployments. WLC is a device that assumes a central role in the CUWN. Traditional roles of access points, such as association or authentication of wireless clients, are done by the WLC. Access points, called Lightweight Access Points (LAPs) in the unified environment, register themselves with a WLC and tunnel all the management and data packets to the WLCs, which then switch the packets between wireless clients and the wired portion of the network. All the configurations are done on the WLC. LAPs download the entire configuration from WLCs and act as a wireless interface to the clients. For more information on how a LAP registers with a WLC, refer to the document Lightweight AP (LAP) Registration to a Wireles
