How are custom application ports configured for monitoring across Cisco SD‑WAN controllers?

Custom application ports for monitoring in Cisco SD-WAN are configured by customers within vAnalytics and vSmart. vAnalytics is the platform used for monitoring and reporting, and it needs to be aware of these custom applications to properly collect and display data. vSmart, as the centralized control plane, is responsible for distributing policies that identify and classify traffic, including custom applications, across the SD-WAN fabric. Therefore, both components require this configuration to ensure end-to-end monitoring and policy enforcement. The other options are incorrect because Cisco does not typically add customer-specific custom application ports; this is a customer-driven configuration. While vManage is the primary management interface, the specific configuration for custom application monitoring ports for analytics and control plane policy distribution resides in vAnalytics and vSmart, respectively.
