FortiGate 2200E and 2201E fast path architecture

The FortiGate 2200E and 2201E models feature the following front panel interfaces:

  • Two 10/100/1000BASE-T Copper (MGMT1 and MGMT2)
  • Twelve 10/100/1000BASE-T Copper (1 to 12)
  • Eighteen 10/25 GigE SFP+/SFP28 (13 to 28), interface groups: 13 - 16, 17 - 20, 21 - 24, and 25 - 28
  • Four 10/25 GigE SFP+/SFP28 (29, 30, HA1 and HA2), interface groups: 29 - HA1 and 30 - HA2 (the HA interfaces are not connected to the NP6 processor)
  • Four 40 GigE QSFP+ (31 to 34)

You can use the following command to display the FortiGate 2200E or 2201E NP6 configuration. The command output shows four NP6s named NP6_0, NP6_1, and NP6_2 and the interfaces (ports) connected to each NP6. This interface to NP6 mapping is also shown in the diagram above.

The command output also shows the XAUI configuration for each NP6 processor. Each NP6 processor has a 40-Gigabit bandwidth capacity. Traffic passes to each NP6 processor over four 10-Gigabit XAUI links. The XAUI links are numbered 0 to 3.

You can also use the diagnose npu np6 port-list command to display this information.

Distributing traffic evenly among the NP6 processors can optimize performance. For details, see Optimizing NP6 performance by distributing traffic to XAUI links.

You can also add LAGs to improve performance. For details, see Increasing NP6 offloading capacity using link aggregation groups (LAGs).

The HA1 and HA2 interfaces are not connected to the NP6 processors. The HA interfaces are instead mapped to a dedicated control path to prevent HA traffic from interfering with the stability and performance of data traffic processing.

Interface groups and changing data interface speeds

FortiGate-2200E and 2201E front panel data interfaces 13 to 30, HA1, and HA2 are divided into the following groups:

  • port13 - port16
  • port17 - port20
  • port21 - port24
  • port25 - port28
  • port29 - ha1
  • port30 - ha2

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 port26 from 25Gbps to 10Gbps the speeds of port25 to port28 are also changed to 10Gbps.

Another example, port17 to port24 interfaces are operating at 25Gbps. If you want to install 10GigE transceivers in port17 to port24 to convert all of these data interfaces to connect to 10Gbps networks, you can enter the following from the CLI:

config system interface

edit port17

set speed 10000full

next

edit port21

set speed 10000full

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 port29 the following message appears:

config system interface

edit port29

set speed 25000full

end

port29 ha1 speed will be changed to 25000full due to hardware limit.
