Splitting front panel network interfaces

You can use the following command to split the FortiController-5903C F1 to F4 or the FortiController-5913C F1 and F2 front panel data network interfaces into 10G interfaces. You can also use this command to split just the F1 interface into 10G interfaces.

config system global

set fabric-front-port-10g-mode {disable | enable | f1-only}

end

Set to disable by default and none of the interfaces are split.

Set to enable to split all of the interfaces as follows:

• Each FortiController-5903C 40Gbps interface is split into four 10Gbps interfaces for a total of sixteen 10Gbps interfaces. The interfaces are named fctrl1/f1-1, fctrl1/f1-2, fctrl1/f1-3, fctrl1/f1-4, fctrl1/f2-1, and so on.

• Each FortiController-5913C 100Gbps interface is split into ten 10Gbps interfaces for a total of twenty 10Gbps interfaces. The interfaces are named fctrl1/f1-1, fctrl1/f1-2, fctrl1/f1-3, fctrl1/f1-4, fctrl1/f1-5, ..., fctrl1/f2-1, fctrl1/f2-2 and so on.

Set to f1-only to split the F1 interface as follows:

• Each FortiController-5903C 40Gbps F1 interface is split into four 10Gbps interfaces named fctrl1/f1-1, fctrl1/f1-2, fctrl1/f1-3, and fctrl1/f1-4.

• Each FortiController-5913C 100Gbps F1 interface is split into ten 10Gbps interfaces named fctrl1/f1-1, fctrl1/f1-2, fctrl1/f1-3, ..., fctrl1/f1-10.

Splitting the FortiController-5903C and FortiController-5913C front panel interfaces may require you to reset the workers to factory defaults and then completely re-configure your SLBC cluster. Fortinet recommends you split interfaces before configuring your cluster to save downtime due to the need to re-do your configuration. In addition, you don't have to split all of the interfaces at the same time, but you should split as many as you will need so that you won't have to re-configure everything in the future if you decide to split some more interfaces. You also have to reconfigure the SLBC cluster if you decide to re-combine some interfaces that were previously split.
