FIM-7941F interface module
Fortinet Technologies Inc.
All of these operations, except changing the interface speed using the
config system interface
command,
require a system restart. Fortinet recommends that you perform these operations during a maintenance window and
plan the changes to avoid traffic disruption. For example, you can change interface types and split interfaces as a single
operation.
You should change interface types or split interfaces on both FortiGate-7000Fs before forming
an FGCP HA cluster. If you decide to change interface type or split interfaces after forming a
cluster, you need to remove the backup FortiGate-7000F from the cluster and change
interfaces as required on both FortiGate-7000Fs separately. After the FortiGate-7000Fs
restart, you can re-form the cluster. This process will cause traffic interruptions.
Changing the P19 or P20 interface type to 100GigE QSFP28
You can use the following command to convert the P19 or P20 interface to a 100GigE QSFP28 interface. To change the
interface type of P19 of the FIM-7941F in slot 1 (1-P19) and P20 of the FIM-7941F in slot 2 (2-P20) enter the following
command:
config system global
set qsfpdd-100g-port 1-P19 2-P20
end
The FortiGate-7000F reboots and when it starts up interface 1-P19 and 2-P20 are operating as 100GigE QSFP28
interfaces.
Splitting the P19 or P20 interfaces into four 100GigE CR2 interfaces
You can use the following command to split the P19 or P20 interfaces into four 100GigE CR2 interfaces. To split P19 of
the FIM-7941F in slot 1 (1-P19) and P20 of the FIM-7941F in slot 2 (2-P20) enter the following command:
config system global
set split-port 1-P19 2-P20
end
The FortiGate-7000F reboots and when it starts up:
l
Interface 1-P19 has been replaced by four 100GigE CR2 interfaces named 1-P19/1 to 1-P19/4.
l
Interface 2-P20 has been replaced by four 100GigE CR2 interfaces named 2-P20/1 to 2-P20/4.
Splitting the P19 or P20 interfaces into four 25GigE CR or 10GigE SR interfaces
You can use the following command to split the P19 or P20 interfaces into four 25GigE CR interfaces. The following
command converts the interface into a 100GigE QSFP28 interface then splits this interface into four 25 GigE CR
interfaces. To change P19 of the FIM-7941F in slot 1 (1-P19) and P20 of the FIM-7941F in slot 2 (2-P20) enter the
following command:
config system global
set qsfpdd-100g-port 1-P19 2-P20
set split-port 1-P19 2-P20
end
