FortiGate-5001E and 5001E1 fast path architecture

The FortiGate-5001E and 5001E1 features two NP6 processors and an integrated switch fabric. The integrated switch fabric allows you to configure aggregate interfaces between interfaces connected to different NP6s and supports offloading between for traffic entering and exiting from any interfaces.

The NP6s are connected to network interfaces as follows:

  • NP6_0 is connected to port1, port3, fabric1, and base1.
  • NP6_1 is connected to port2, port4, fabric2, and base2.

The following diagram also shows the XAUI port connections between the NP6 processors and the front panel interfaces and the integrated switch fabric.

NP6 default interface mapping

You can use the following get command to display the FortiGate-5001E 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.

NP6 interface mapping with split ports

If you use the following CLI command to split port1:

config system global

set split-port port1

end

The new split ports (port1/1 to port 1/4) are mapped to the same NP6 as the un-split port1 interface:
