Cisco vManage and SD-WAN Basics
Cisco SD-WAN centralizes WAN management using the vManage dashboard, separating the control plane (vSmart) from the data plane (vEdge/cEdge routers).
The Evolution to SD-WAN
Traditional WANs rely heavily on expensive MPLS circuits and manual configuration of branch routers. Software-Defined WAN (SD-WAN) applies SDN principles to the WAN, allowing organizations to securely mix and match transport links (MPLS, Broadband, LTE) and route traffic intelligently based on application performance and policies.
The Role of vManage
**vManage** is the centralized management plane for the Cisco SD-WAN solution. It provides a GUI dashboard (a single pane of glass) where administrators can configure policies, monitor network health, and automate the provisioning of branch routers (Zero Touch Provisioning). It is the equivalent of DNA Center, but for the WAN.
Other Key SD-WAN Components
A full Cisco SD-WAN deployment includes other planes: - **vSmart (Control Plane):** Distributes routing information and policies to the edge routers. - **vBond (Orchestration Plane):** Authenticates devices and coordinates initial connectivity. - **vEdge/cEdge (Data Plane):** The actual routers at branch locations that forward the traffic.
❓ Frequently Asked Questions
What is the management interface for Cisco SD-WAN?
vManage is the centralized graphical management interface.
Can SD-WAN use commodity internet connections?
Yes, SD-WAN can securely utilize standard broadband internet (via IPsec tunnels) alongside or instead of MPLS.
What component handles the data plane in Cisco SD-WAN?
The WAN Edge routers (vEdge or cEdge) handle the actual forwarding of data traffic.
