Determining the primary FPC

You can determine which FPC is operating as the primary (master) FPC by using the diagnose load-balance status command.

The following example diagnose load-balance status output for a FortiGate-6301F shows that the FPC in slot 1 is the primary (master) FPC. The command output also shows the status of all of the FPCs in the FortiGate-6301F.
