FortiGate-2000E fast path architecture

The FortiGate-2000E includes three NP6 processors in an NP Direct configuration. The NP6 processors connected to the 10GigE ports are also in a low latency NP Direct configuration. Because of NP Direct, you cannot create Link Aggregation Groups (LAGs) between interfaces connected to different NP6s. As well, traffic will only be offloaded if it enters and exits the FortiGate on interfaces connected to the same NP6.

The NP6s are connected to network interfaces as follows:

  • NP6_0 is connected to four 10GigE SFP+ interfaces (port33 to port36) in a low latency configuration.
  • NP6_1 is connected to thirty-two 10/100/1000BASE-T interfaces (port1 to port32).
  • NP6_2 is connected to two 10GigE SFP+ (port37 and port38) in a low latency configuration.

The following diagram also shows the XAUI and QSGMII port connections between the NP6 processors and the front panel interfaces and the aggregate switch for the thirty-two 10/100/1000BASE-T interfaces.


You can use the following get command to display the FortiGate-2000E NP6 configuration. You can also use the diagnose npu np6 port-list command to display this information.
