Question
The management VILAN is used to transmit packets that are forwarded through CAPWAP tunnels, including management packets and service data packets forwarded through CAPWAP tunnels.
A. True
B. False
Answer
A. True
Explanation
The management VLAN (Virtual LAN) is specifically used to carry CAPWAP (Control and Provisioning of Wireless Access Points) tunnel traffic, which includes both management packets and service data packets forwarded through CAPWAP tunnels. CAPWAP is a protocol used for controlling and managing wireless access points (APs) in a centralized wireless LAN architecture.
In a CAPWAP-based wireless network, the APs establish CAPWAP tunnels with a centralized WLAN controller. These tunnels encapsulate and transmit the following types of traffic:
- Management packets: These packets are used for configuring, monitoring, and controlling the APs from the WLAN controller.
- Service data packets: These packets represent the user data traffic (e.g., web browsing, VoIP, video streaming) that is forwarded through the CAPWAP tunnels from the APs to the WLAN controller and vice versa.
By using a dedicated management VLAN for CAPWAP tunnel traffic, it ensures separation and prioritization of the critical control and data traffic from other types of network traffic. This separation helps in maintaining efficient and secure communication between the APs and the WLAN controller.
