The FortiGate-3815D features four front panel 100Gigabit interfaces (port1 to port 4) and ten front panel 10Gigabit interfaces (port5 to port14) and eight NP6 processors connected to an Integrated Switch Fabric (ISF). Individual interfaces are not mapped to NP6 processors. Instead an Aggregator connects the front panel interfaces to the ISF. Because of the aggregator, no special mapping is required for fastpath offloading.
You can use the following diagnose command to display the FortiGate-3815D NP6 configuration. The command output shows all NP6s connected to each interface (port) with cross-chip offloading supported for each port.
