Frequently Asked Questions
What is a wireless LAN controller?
A wireless LAN controller centrally manages many lightweight access points, handling configuration, roaming, security policy and monitoring. It replaces managing each access point individually.
What is CAPWAP?
CAPWAP is the protocol access points use to talk to a controller, carrying control messages and optionally client traffic in tunnels. It evolved from Cisco's earlier LWAPP.
What is the difference between autonomous and lightweight APs?
Autonomous APs run independently with their own configuration, while lightweight APs depend on a controller. This free Codelivly room explains why enterprises prefer the controller model.
