Interface groups and changing data interface speeds

Interface groups and changing data interface speeds

Depending on the networks that you want to connect your FortiGate-6000 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
  • port5 - port8
  • port9 - port12
  • port13 - port16
  • port17 - port20
  • port21 - port24

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 the same 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.

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 must 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

Every time you change a data interface speed, when you enter the end command, the CLI confirms the range of interfaces affected by the change. For example, if you change the speed of port5 the following message appears:

config system interface

edit port5

set speed 25000full

end

port5-port8 speed will be changed to 25000full due to hardware limit.
