In an SD-Access deployment, a fabric edge node performs the function of connecting endpoints to the fabric and forwarding their traffic.
SD-Access (Software-Defined Access) is a Cisco technology that uses a fabric-based architecture to simplify network design, operation, and management. The fabric edge nodes are one of the key components of the SD-Access architecture, along with the control plane nodes, border nodes, and fabric underlay.
The fabric edge nodes connect endpoints (such as users, servers, and IoT devices) to the SD-Access fabric, which is a virtualized network overlay that provides segmentation, policy, and automation services. The edge nodes use VXLAN (Virtual Extensible LAN) encapsulation to tunnel the endpoint traffic over the fabric underlay.
The edge nodes also enforce the policies that are defined in the SD-Access control plane, which is based on Cisco Identity Services Engine (ISE) and Cisco DNA Center. These policies can be based on user identity, device type, location, time of day, and other factors, and they can control access, security, quality of service, and other aspects of the network.
In summary, the fabric edge nodes in an SD-Access deployment perform the critical function of connecting endpoints to the fabric and forwarding their traffic, while also enforcing the policies that define the behavior of the network.
