Which device in the SD-WAN solution receives and categorizes event reports, and generates alarms?

WAN Edge routers are data plane devices that forward traffic and send telemetry data, but they do not centrally categorize events or generate alarms for the entire fabric.

vSmart controllers are control plane devices that distribute policies and routing information, but they are not responsible for centralized event categorization or alarm generation.

The vManage NMS acts as the central management plane for the Cisco SD-WAN solution, providing a single pane of glass for monitoring, configuration, and troubleshooting. It aggregates event reports from all devices, categorizes them, and generates alarms to alert administrators to network issues.

vBond controllers serve as orchestrators for initial device onboarding and discovery, not for ongoing event management or alarm generation.
