What is the function of the edge node in Cisco SD-Access fabric?

The function of the edge node in Cisco SD-Access fabric is focused on the authentication and registration of endpoints. This role is critical in ensuring that devices connecting to the network are properly validated and configured according to the policies defined in the fabric. When an endpoint connects to the network, the edge node performs processes such as identity and access management, which includes authenticating the user or device, assigning necessary resources, and applying predefined policies that govern network access.

This functionality promotes enhanced security and provides a structured way to manage endpoint devices, thereby ensuring that only authorized users can access the network and that they receive appropriate network resources based on their role or requirements. By handling these processes at the edge of the fabric, the network provides a more streamlined experience for both the user and the network administrator.
