Relying solely on predefined probes to verify the Layer 3 service status of circuits can limit the flexibility and accuracy of path selection. To provide more granular control and leverage existing performance monitoring, Prisma SD-WAN now supports configurable service health probes to determine the Layer 3 service status of a circuit. This feature allows you to optionally use application and link performance probes to verify the Layer 3 service status of a circuit, providing a unified and consistent approach to path health verification.
