On a large enterprise network, multiple ACs are typically deployed to expand the network capacity or improve network reliability. In a multi-AC scenario, users need to apply for licenses for each AC, and the licenses are unique for the ACs. Centralized license control enables an AC as the license server to manage all license resources. Other ACs serve as license clients to report local licenses to the license server. When an AP goes online on an AC, the license client needs to apply for a license from the license server. When an AP goes offline from an AC, the license client can notify the license server of the going-offline event, and the license server releases the corresponding license resource. Centralized license control achieves unified license management and flexible license allocation, making license use simple and efficient.
