FortiGate 100F and 101F fast path architecture

The FortiGate 100F and 101F includes the SOC4 and uses the SOC4 CPU, NP6XLite processor, and CP9XLite processor. All of the data interfaces and the HA and MGMT interfaces connect to the SOC4. The DMZ and MGMT interfaces connect directly to the SOC4. Other data interfaces and the HA interfaces connect to the SOC4 through the integrated switch fabric. All supported traffic passing between any two interfaces can be offloaded by the SOC4 NP6XLite processor. Traffic processed by the CPU takes a dedicated data path through the ISF and the NP6XLite processor to the CPU.

Interfaces 17 to 20 are shared SFP or Ethernet interfaces. That means there are two sets of physical interfaces numbered 17 to 20 but only one of each can be connected to a network. This allows you to, for example, connect interfaces 17 and 18 to an SFP switch and interfaces 19 and 20 to a 10/100/1000BASE-T Copper switch.

The FortiGate 100F and 101F models feature the following front panel interfaces:

• Two 10/100/1000BASE-T Copper (DMZ, MGMT).
• Sixteen 10/100/1000BASE-T Copper (WAN1, WAN2, HA1, HA2, 1 to 12).
• Two 10 GigE SFP+ (X1 and X2). X1 and X2 are FortiLink interfaces.
• Four 1GigE SFP (13 to 16).
• Four shared interfaces (17 to 20) that can be either:
  • 10/100/1000BASE-T Copper
  • 1GE SFP

You can use the command diagnose npu np6xlite port-list to display the FortiGate 100F or 101F NP6XLite configuration.
