What is a difference between autonomous APs and controller-based APs in wireless LANs?
- Controller-based APs support PAgP and LACP protocols, whereas autonomous APs do not.
- Autonomous APs are easier to configure and manage than are controller-based APs.
- Autonomous APs require no initial configuration, whereas the lightweight APs require an initial configuration before communicating with a WLAN controller.
- When wireless demands increase, controller-based APs provide a better solution than do autonomous APs.
Explanation: When the wireless demands increase, more autonomous APs would be required. Each of them operates independently of the others and each one requires manual configuration and management. This would become overwhelming if many APs are needed. Controller-based APs require no initial configuration and are often called lightweight APs. Controller-based APs are useful in situations where many APs are required in the network. As more APs are added, each AP is automatically configured and managed by the WLC. The WLC does not support PaGP or LACP.
