In a Cisco SD-Access deployment, the fabric AP (Access Point) serves as a connection point for wireless clients to the fabric network. The AP facilitates the entry of wireless clients into the fabric by providing them with access to network services and connectivity. The role of the AP in this context is to ensure that wireless clients can seamlessly become part of the fabric, which is an overlay network architecture that provides scalable, flexible access control and segmentation.
