FortiGate–3100D fast path architecture

The FortiGate-3100D features 32 SFP+ 10Gb interfaces connected to two NP6 processors through an Integrated Switch Fabirc (ISF). The FortiGate-3100D has the following fastpath architecture:

l  16 SFP+ 10Gb interfaces, port1 through port16 share connections to the first NP6 processor (np6_0).

l  16 SFP+ 10Gb interfaces, port27 through port32 share connections to the second NP6 processor (np6_1).

You can use the following get command to display the FortiGate-3100D NP6 configuration. The command output shows two NP6s named NP6_0 and NP6_1 and the interfaces (ports) connected to each NP6. You can also use the diagnose npu np6 port-list command to display this information.
