Learn PfRv3 Settings
The Learn PfRv3 Settings feature allows users to easily setup the PfR/IWAN semantics to monitor Performance. These Settings will allow LiveNX to populate the WAN/PfR dashboard. The settings learned are as follows:
• PfRv3 devices including master controller and border router loopback IP address at each site
• Sites
• WAN Tunnels
• Capacities of the WAN Tunnels
• Service Providers
• Site IP Addresses

The Learning process will analyze flow data being sent by the PfR enabled devices in the network. Options include 1 hour, 1 day, 1 week and a Custom time range. Once the process completes you will see the sites that were learned (including the Loopback IP addresses of the Master Controller (MC) associated with each site).
