FortiGate-3815D fast path architecture

The FortiGate-3815D features four front panel 100GigE CFP2 interfaces and eight 10GigE SFP+ interfaces connected to eight NP6 processors through an Integrated Switch Fabric (ISF). Individual interfaces are not mapped to NP6 processors because of the integrated switch fabric. No special mapping is required for fastpath offloading or aggregate interfaces.


You can use the following get 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. You can also use the diagnose npu np6 port-list command to display this information.
