FortiGate 1500DT fast path architecture

The FortiGate 1500DT features two NP6 processors both connected to an integrated switch fabric. The FortiGate 1500DT has the same hardware configuration as the FortiGate 1500D, but with the addition of newer CPUs and a slightly different interface configuration.

The FortiGate 1500DT includes the following interfaces and NP6 processors:

  • Eight SFP 1Gb interfaces (port1-port8), eight RJ-45 1Gb Ethernet interfaces (port17-24) and four RJ-45 10Gb Ethernet interfaces (port33-port36) share connections to the first NP6 processor.
  • Eight SFP 1Gb interfaces (port9-port16), eight RJ-45 1Gb Ethernet ports (port25-32) and four SFP+ 10Gb interfaces (port37-port40) share connections to the second NP6 processor.

You can use the following get command to display the FortiGate 1500DT 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 1500DT connections per second performance

On the FortiGate 1500DT, 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 1500DT is processing very large numbers sessions with short life times, you can try enabling this feature to see if performance improves.
