What distinguishes CAPWAP data messages from control messages?

The distinction between CAPWAP data messages and control messages lies in the encapsulation of wireless client packets. CAPWAP (Control and Provisioning of Wireless Access Points) is designed to facilitate communication between access points and a controller in a wireless LAN architecture.

Data messages are responsible for carrying encapsulated packets that are transmitted between the wireless client devices and the wired network, effectively handling user traffic. In contrast, control messages are utilized for managing and configuring the access points. These messages include information needed for the setup, maintenance, and operation of the wireless access point, without actually carrying the user traffic itself.

This encapsulation process ensures that user data can be efficiently transported while control messages remain focused on the configuration and control aspects of the wireless network. The correct choice highlights this essential aspect of CAPWAP communication, emphasizing the role of data messages in transporting user packets and differentiating them from control messages.
