Configure Application Reachability Probes

Learn more about the Prisma SD-WAN application reachability probes.
Configure application probes to check an application's reachability for a given path for an ION device. Application probes are initiated on detection of an unreachable prefix for an application. You may configure application reachability probes on any valid Layer 3 LAN interface.
Application probe is enabled by default for all ION devices, except for ION 1000. The controller port generates the application probes if you do not configure any LAN ports for generating application probes.
For the ION 1000 device, you must configure a LAN port for the application probe. If not, the controller generates an alarm. You can choose to exclude specific circuits and circuit categories from being used for checking the reachability of an application on a given path. Refer Configure Device Initiated Connections.
