NP Direct

On FortiGates with more than one NP6 processor, removing the Internal Switch Fabric (ISF) for NP Direct architecture provides direct access to the NP6 processors for the lowest latency forwarding. Because the NP6 processors are not connected, care must be taken with network design to make sure that all traffic to be offloaded enters and exits the FortiGate through interfaces connected to the same NP6 processor. As well Link Aggregation (LAG) interfaces should only include interfaces all connected to the same NP6 processor.

Example NP direct hardware with more than one NP6 processor includes:

  • Ports 25 to 32 of the FortiGate 3700D in low latency mode.
  • FortiGate 2000E
  • FortiGate 2500E
