Interface Groups And Changing Data Interface Speeds - Fortinet FortiGate 6000F Series System Manual

FortiGate 6000F series hardware description
Two front panel 1/10GigE SFP+ HA interfaces (HA1 and HA2) used for heartbeat, session sync, and management
l
communication between two and only two FortiGate 6000Fs in an HA cluster. The default speed of these interfaces
is 10Gbps. Operating them at 1Gbps is not recommended. A FortiGate 6000F cluster consists of two (and only two)
FortiGate 6000Fs of the same model. To set up HA, you can use a direct cable connection between the FortiGate
6000Fs HA1 interfaces and between their HA2 interfaces.
Two 10/100/1000BASE-T out of band management Ethernet interfaces (MGMT1 and MGMT2).
l
One front panel 1/10GigE SFP+ out of band management interface (MGMT3).
l
One RJ-45 RS-232 serial console connection.
l
One USB connector.

Interface groups and changing data interface speeds

Depending on the networks that you want to connect your FortiGate 6000F to, you may have to manually change the
data interface speeds. The port1 to port24 data interfaces are divided into the following groups:
port1 - port4
l
port5 - port8
l
port9 - port12
l
port13 - port16
l
port17 - port20
l
port21 - port24
l
All of the interfaces in a group operate at the same speed. Changing the speed of an interface changes the speeds of all
of the interfaces in that group. For example, if you change the speed of port18 from 10Gbps to 25Gbps the speeds of
port17 to port20 are also changed to 25Gbps.
The port25 to port28 interfaces are not part of an interface group. You can set the speed of each of these interfaces
independently of the other three.
Another example, the default speed of the port1 to port24 interfaces is 10Gbps. If you want to install 25GigE transceivers
in port1 to port24 to convert these data interfaces to connect to 25Gbps networks, you can enter the following from the
CLI:
config system interface
edit port1
set speed 25000full
next
edit port5
set speed 25000full
next
edit port9
set speed 25000full
next
edit port13
set speed 25000full
next
edit port17
set speed 25000full
next
edit port21
set speed 25000full
end
