Description
This article provides guidance on how to perform split ports on FortiGate 7000 series.

Solution
The Fortigate 7000 series FIM Module supports split port feature.
FIM-7904E    - Each 40G port can be split into 4x10G/1G interface
FIM-7910E    - Each 100G port can be split into 10x10G interfaces
FIM-7920E    - Each 40G port can be split into 4x10G interfaces

The following command can be used to split ports:

# config system global
    set split-port <port>
end

Splitting the interfaces requires a system reboot. Multiple interfaces may be split at the same time.

For example, to split the B1 interface of the FIM-7904E in slot 1 (this interface is named 1-B1) and the B1 and B4 interfaces of the FIM-7904E in slot 2 (these interfaces are named 2-B1 and 2-B4) connect to the CLI of the FortiGate-7000 system using the management IP and enter the following command:

# config system global
    set split-port 1-B1 2-B1 2-B4
end
System will reboot to make the setting take effect.
Do you want to continue? (y/n) y

After entering the command, the FortiGate-7000 goes into a reboot.
After the system boots up, the following changes take place:

The 1-B1 interface will no longer be available. Instead the 1-B1/1, 1-B1/2, 1-B1/3, and 1-B1/4 interfaces will be available.
The 2-B1 interface will no longer be available. Instead the 2-B1/1, 2-B1/2, 2-B1/3, and 2-B1/4 interfaces will be available.
The 2-B4 interface will no longer be available. Instead the 2-B4/1, 2-B4/2, 2-B4/3, and 2-B4/4 interfaces will be available.
