Role of the vSmart Controller

B.

In a Cisco SD-WAN environment, the vSmart controller plays a critical role in managing the control plane of the network. The control plane is responsible for determining the optimal path for network traffic and communicating that information to the data plane.

Specifically, the vSmart controller is responsible for the following tasks:

1. Overlay routing: The vSmart controller is responsible for configuring and managing the overlay routing protocols used in the SD-WAN environment. These protocols allow the SD-WAN edge devices to discover and communicate with each other, and to determine the best path for traffic based on policies and network conditions.

2. Policy enforcement: The vSmart controller is responsible for enforcing policies that determine how traffic should be routed through the network. These policies can be based on a variety of factors, including application type, user identity, and network conditions.

3. Centralized management: The vSmart controller provides a centralized management system for the SD-WAN environment. This includes configuration management, monitoring and reporting, and troubleshooting tools.

4. Security: The vSmart controller provides a secure communication channel for SD-WAN edge devices, and can enforce security policies for traffic flowing through the network.

In summary, the vSmart controller is a key component of a Cisco SD-WAN environment, responsible for managing the control plane, enforcing policies, providing centralized management, and ensuring network security.
