The Cisco SD-WAN vManage Troubleshooting Dashboard APIs capture various details during troubleshooting, including the connections summary. This summary provides an overview of all control connections from the vManage NMS to the vSmart controllers, WAN Edge routers, and vBond orchestrators in the overlay network. It displays the status of these connections, which is crucial during a network outage to identify and troubleshoot the cause of the issue.
