FortiGate 1200D fast path architecture
The FortiGate 1200D features two NP6 processors both connected to an integrated switch fabric.
- Eight SFP 1Gb interfaces (port1-port8), eight RJ-45 Ethernet ports (port17-24) and two SFP+ 10Gb interfaces (port33 and port34) share connections to the first NP6 processor.
- Eight SFP 1Gb interfaces (port9-port16), eight RJ-45 Ethernet ports (port25-32) and two SFP+ 10Gb interfaces (port35-port36) share connections to the second NP6 processor.
You can use the following get command to display the FortiGate 1200D NP6 configuration. The command output shows two NP6s named NP6_0 and NP6_1. The output also shows the interfaces (ports) connected to each NP6. You can also use the diagnose npu np6 port-list command to display this information.

Improving FortiGate 1200D connections per second performance
On the FortiGate 1200D, you can use the following command to potentially improve connections per second (CPS) performance:
config system npu
set np6-cps-optimization-mode {disable | enable}
end
Disabled by default, enabling this option can increase CPS performance by using more CPUs for interrupt processing. If your FortiGate 1200D is processing very large numbers sessions with short life times, you can try enabling this feature to see if performance improves.
