Which protocol does an SD-Access wireless Access Point use for its fabric data plane?

In Cisco SD-Access architecture, fabric-enabled wireless APs connect to the network usingCAPWAPfor control, but their data plane is integrated into thefabric overlayusingVXLAN (Virtual Extensible LAN).

VXLANis the data plane encapsulation used between fabric nodes, including wireless APs that are part of the SD-Access fabric.

WhileCAPWAP (E)remains in use for management and control communication between the AP and wireless LAN controller (WLC), actual user traffic is encapsulated in VXLAN for fabric forwarding.

This separation of control and data plane ensures seamless mobility, segmentation, and policy enforcement within the SD-Access fabric.
