Determining the primary FPM

You can use the diagnose load-balance status command to determine which FPM is operating as the primary (master) FPM.

You can also use the execute load-balance slot set-master-worker command to temporarily make an FPM the primary FPM.

The following example diagnose load-balance status output for a FortiGate-7121F shows that the FPM in slot 3 is the primary (master) FPM. The command output also shows the status of the FPMs in slots 3 to 6 of the FortiGate-7121F.
