FortiGate 3100D fast path architecture
The FortiGate 3100D features 32 SFP+ 10Gb interfaces connected to two NP6 processors through an Integrated Switch Fabric (ISF). The FortiGate 3100D has the following fastpath architecture:
- 16 SFP+ 10Gb interfaces, port1 through port16 share connections to the first NP6 processor (np6_0).
- 16 SFP+ 10Gb interfaces, port27 through port32 share connections to the second NP6 processor (np6_1).
The FortiGate 3100D supports enhanced load balancing for LAG interfaces, see Enhanced load balancing for LAG interfaces for NP6 platforms.
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.
