The app probes class in Cisco SD-WAN policy object configurations is a policy object used to define how application traffic is marked and forwarded based on QoS parameters, this enabling optimized path selection in the SD-WAN fabric.
Example-1: This example demonstrates how to configure an App Probe Class containing multiple App Probes. Each App Probe is identified by its name and can include various probe configurations. The forwarding_class is used to specify the class map that the App Probe belongs to, and mappings can include color and DSCP values.
