Splitting The Fim-7910E C1 To C4 Interfaces - Fortinet FortiGate-7060E Handbook

FIM-7910E interface module
The FIM-7910E includes the following hardware features:
Four front panel 100GigE CFP2 fabric channel interfaces (C1 to C4). These interfaces are connected to 100Gbps
l
networks to distribute sessions to the FPM processor modules installed in chassis slots 3 and up. Using 100GBASE-
SR10 multimode CFP2 transceivers, each CFP2 interface can also be split into ten 10GBASE-SR interfaces. These
interfaces also support creating link aggregation groups (LAGs) that can include interfaces from both FIM-7910Es.
Two front panel 10GigE SFP+ interfaces (M1 and M2) that connect to the base backplane channel. These
l
interfaces are used for heartbeat, session sync, and management communication between FIM-7910Es in different
chassis. These interfaces can also be configured to operate as Gigabit Ethernet interfaces using SFP transceivers,
but should not normally be changed. If you use switches to connect these interfaces, the switch ports should be
able to accept packets with a maximum frame size of at least 1526. The M1 and M2 interfaces need to be on
different broadcast domains. If M1 and M2 are connected to the same switch, Q-in-Q must be enabled on the
switch.
Four 10/100/1000BASE-T out of band management Ethernet interfaces (MGMT1 to MGMT4).
l
One 80Gbps fabric backplane channel for traffic distribution with each FPM module installed in the same chassis as
l
the FIM-7910E.
One 1Gbps base backplane channel for base backplane with each FPM module installed in the same chassis as the
l
FIM-7910E.
One 40Gbps fabric backplane channel for fabric backplane communication with the other FIM-7910E in the chassis.
l
One 1Gbps base backplane channel for base backplane communication with the other FIM-7910E in the chassis.
l
On-board DP2 processors and an integrated switch fabric to provide high-capacity session-aware load balancing.
l
One front panel USB port.
l
Power button.
l
NMI switch (for troubleshooting as recommended by Fortinet Support).
l
Mounting hardware.
l
LED status indicators.

Splitting the FIM-7910E C1 to C4 interfaces

Each 100GE interface (C1 to C4) on the FIM-7910Es in slot 1 and slot 2 of a FortiGate-7000 system can be split
into 10 x 10GBE interfaces. You split these interfaces after the FIM-7910Es are installed in your FortiGate-7000
system and the system us up and running. You can split the interfaces of the FIM-7910Es 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-7910E in slot 1 (this interface is named 1-C1) and the C1 and C4
interfaces of the FIM-7910E 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, ..., and 1-C1/10 interfaces will be
l
available.
The 2-C1 interface will no longer be available. Instead the 2-C1/1, 2-C1/2, ..., and 2-C1/10 interfaces will be
l
available.
