Network Controller and Fabric Edge Node

AE.

Sure, I'd be happy to explain the device roles in Cisco SD-Access fabric!

Cisco SD-Access (Software-Defined Access) is a solution that provides automated policy-based segmentation of the network using software-defined networking (SDN) principles. It is designed to simplify network management, increase security, and improve scalability.

In the Cisco SD-Access fabric, there are several device roles that serve different purposes. Here are brief explanations of each device role:

A. Edge Node: The Edge Node is the access layer device that connects end devices to the fabric. It can be a switch, wireless access point, or router. The Edge Node is responsible for authenticating end devices and enforcing policies.

C. Access Switch: The Access Switch is an Ethernet switch that connects end devices to the network. It provides network access to end devices and enforces policies defined in the fabric.

D. Core Switch: The Core Switch is responsible for forwarding traffic between the different segments of the fabric. It provides high-speed connectivity and is typically located in the data center.

E. Border Node: The Border Node is the device that connects the SD-Access fabric to other networks or the Internet. It acts as a gateway between the fabric and external networks, and enforces policies for traffic leaving or entering the fabric.

B. vBond Controller: The vBond Controller is the centralized orchestrator for the fabric. It is responsible for authenticating and authorizing all devices in the fabric, as well as distributing policies and configurations to the devices. The vBond Controller is a virtual machine that can be hosted in a cloud or on-premises.

In summary, the two device roles in Cisco SD-Access fabric are Edge Node and vBond Controller. The Edge Node is responsible for connecting end devices to the fabric and enforcing policies, while the vBond Controller is the centralized orchestrator for the fabric.
