Splitting The C1 To C4 Interfaces - Fortinet FortiGate-7060E Handbook

FIM-7904E interface module
Changing the interface type
For example, to change the interface type of the C1 interface of the FIM-7920E in slot 1 to 40GE QSFP+ connect
to the CLI of your FortiGate-7000 system using the management IP and enter the following command:
config system global
set qsfp28-40g-port 1-C1
end
The FortiGate-7000 system reboots and when it starts up interface C1 of the FIM-7920E in slot 1 is operating as
a 40GE QSFP+ interface .
To change the interface type of the C3 and C4 ports of the FIM-7920E in slot 2 to 40GE QSFP+ enter the
following command:
config system global
set qsfp28-40g-port 2-C3 2-C4
end
The FortiGate-7000 system reboots and when it starts up interfaces C3 and C4 of the FIM-7920E in slot 2 are
operating as a 40GE QSFP+ interfaces.

Splitting the C1 to C4 interfaces

Each 40GE interface (C1 to C4) on the FIM-7920Es in slot 1 and slot 2 of a FortiGate-7000 system can be split
into 4 x 10GBE interfaces. You split these interfaces after the FIM-7920Es are installed in your FortiGate-7000
system and the system us up and running. You can split the interfaces of the FIM-7920Es in slot 1 and slot 2 at
the same time by entering a single CLI command. Splitting the interfaces requires a system reboot so Fortinet
recommends that you split multiple interfaces at the same time according to your requirements to avoid traffic
disruption.
For example, to split the C1 interface of the FIM-7920E in slot 1 (this interface is named 1-C1) and the C1 and C4
interfaces of the FIM-7920E in slot 2 (these interfaces are named 2-C1 and 2-C4) connect to the CLI of your
FortiGate-7000 system using the management IP and enter the following command:
config system global
set split-port 1-C1 2-C1 2-C4
end
After you enter the command, the FortiGate-7000 reboots and when it comes up:
The 1-C1 interface will no longer be available. Instead the 1-C1/1, 1-C1/2, 1-C1/3, and 1-C1/4 interfaces will be
l
available.
The 2-C1 interface will no longer be available. Instead the 2-C1/1, 2-C1/2, 2-C1/3, and 2-C1/4 interfaces will be
l
available.
The 2-C4 interface will no longer be available. Instead the 2-C4/1, 2-C4/2, 2-C4/3, and 2-C4/4 interfaces will be
l
available.
You can now connect breakout cables to these interfaces and configure traffic between them just like any other
FortiGate interface.
FIM-7920E hardware schematic
The FIM-7920E includes an integrated switch fabric (ISF) that connects the front panel interfaces to the DP2
session-aware load balancers and to the chassis backplanes. The ISF also allows the DP2 processors to
