FortiGate 2000E fast path architecture

The FortiGate 2000E features the following front panel interfaces:

  • Two 10/100/1000BASE-T Copper interfaces (MGMT1 and MGMT2, not connected to the NP6 processors)
  • Thirty-two 10/100/1000BASE-T interfaces (1 to 32)
  • Four 10GigE SFP+ interfaces (33 to 36)
  • Two 10GigE SFP+ (37 and 38)

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) or redundant interfaces 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 33 to 36 in a low latency configuration
  • NP6_1 is connected to 1 to 32
  • NP6_2 is connected to 37 and 38 n 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.

All data traffic passes from the data interfaces to the NP6 processors. Data traffic processed by the CPU takes a dedicated data path through the ISF and an NP6 processor to the CPU.

The MGMT interfaces are not connected to the NP6 processors. Management traffic passes to the CPU over a dedicated management path that is separate from the data paths. You can also dedicate separate CPU resources for management traffic to further isolate management processing from data processing (see Dedicated management CPU). This separation of management traffic from data traffic keeps management traffic from interfering with the stability and performance of data traffic processing.

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.
