Determining the primary FPC

You can determine which FPC is operating as the primary (master) FPC by hovering over the FPCs in the Security Fabric dashboard widget. The FPC operating as the primary FPC will have a Status of Master Blade.

You can use the diagnose load-balance status command to determine which FPC is operating as the primary FPC.

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.
