Configure Active Flow Monitoring Logs for NAT44/NAT64


Active Flow Monitoring logs are generated for NAT44 /NAT64 sessions to create or delete events on MX-SPC3 devices.


This example uses the following hardware and software components:

  • MX480 and MX960 with MX-SPC3
  • Junos OS Release 21.2R1


To configure Active Flow Monitoring logging on MX-SPC3 devices, perform these tasks:

  1. Configure the collectors on an interface.

  2. Configure the collector groups.

  3. Configure the template profiles and associate the template profile with the collector or collector group.

  4. Associate the template profile with the template type.

  5. Associate the template profile with the version.

  6. Assign the refresh-rate values.

  7. Associate the template profile with the service set.


From the configuration mode, confirm your configuration by entering the show services jflow-log command in configuration mode. If the output does not display the intended configuration, repeat the instructions in this example to correct the configuration.
