How does CAPWAP communicate between an access point in local mode and a WLC?

CAPWAP stands for Control and Provisioning of Wireless Access Points, which is a standard protocol used by wireless LAN controllers (WLCs) to communicate with wireless access points (APs). This protocol enables the WLC to manage and control APs in order to create a wireless network infrastructure.
In order for CAPWAP to communicate between an access point in local mode and a WLC, there are several requirements that need to be met:
B. The access point must be connected to the same switch as the WLC This is because CAPWAP communication typically occurs over Layer 2 or Layer 3 networks. When an access point is connected to the same switch as the WLC, they can communicate with each other through the same VLAN or subnet.
D. The access point has the ability to link to any switch in the network, assuming connectivity to the WLC This is because CAPWAP communication can also occur over Layer 3 networks, which means that the access point can connect to any switch in the network as long as it has connectivity to the WLC. This can be achieved through routing protocols or by configuring the access point's default gateway to be the IP address of the WLC.
A. The access point must not be connected to the wired network, as it would create a loop This is incorrect as the access point must be connected to the wired network to function properly. However, care must be taken to prevent network loops, which can occur if there are multiple paths between the access point and the WLC.
C. The access point must directly connect to the WLC using a copper cable This is also incorrect as CAPWAP communication can occur over both wired and wireless networks. While a direct connection between the access point and the WLC may provide optimal performance and security, it is not a requirement for CAPWAP communication to function.
In summary, CAPWAP communication between an access point in local mode and a WLC can occur over both wired and wireless networks, and the access point must be connected to the same switch as the WLC or have connectivity to the WLC through routing protocols or default gateway configuration.
