FortiGate 1500D fast path architecture
The FortiGate 1500D features two NP6 processors both connected to an integrated switch fabric.
- Eight SFP 1Gb interfaces (port1-port8), eight RJ-45 1Gb Ethernet interfaces (port17-24) and four SFP+ 10Gb interfaces (port33-port36) share connections to the first NP6 processor.
- Eight SFP 1Gb interfaces (port9-port16), eight RJ-45 1Gb Ethernet interfaces (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 1500D 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 1500D connections per second performance
On the FortiGate 1500D, 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 1500D is processing very large numbers sessions with short life times, you can try enabling this feature to see if performance improves.
Enabling or disabling np6-cps-optimization-mode requires a system restart. You should only change this setting during a maintenance window or quiet period.
|
A configuration change that causes a FortiGate to restart can disrupt the operation of an FGCP cluster. If possible, you should make this configuration change to the individual FortiGates before setting up the cluster. If the cluster is already operating, you should temporarily remove the secondary FortiGate(s) from the cluster, change the configuration of the individual FortiGates and then re-form the cluster. You can remove FortiGate(s) from a cluster using the Remove Device from HA cluster button on the System > HA GUI page. For more information, see Disconnecting a FortiGate. |
