How does a lightweight access point communicate with a wireless LAN controller?
- Through an IPsec tunnel
- Through a CAPWAP tunnel
- Through a GRE tunnel
- Directly over Layer 2
Lightweight access points (LAPs) communicate with a wireless LAN controller (WLC) using the Control And Provisioning of Wireless Access Points (CAPWAP) protocol. CAPWAP is a standard protocol that is used to control and manage LAPs in a wireless LAN.
It allows the LAPs to communicate with the WLC over the network, and to receive configuration and policy information from the WLC. CAPWAP uses a tunneling mechanism to encapsulate the control messages between the LAPs and the WLC and to ensure that these messages are transmitted securely.
Therefore, the correct answer is: “Through a CAPWAP tunnel”
