FortiGate 300E and 301E fast path architecture
The FortiGate 300E and 301E each include one NP6 processor. All supported traffic passing between any two data interfaces can be offloaded by the NP6 processor. Data traffic to be processed by the CPU takes a dedicated data path through the NP6 processor to the CPU. Interfaces 1 to 16 connect to an integrated switch fabric to allow these sixteen interfaces to share two XAUI ports that connect to the NP6 processor. Interfaces 17 to 28, S1, S2, VW1 and VW2 each connect to one of four QSGMII ports that connect them to the NP6 processor.
The FortiGate 300E and 301E models feature the following front panel interfaces:
- Two 10/100/1000BASE-T Copper (MGNT and HA, not connected to the NP6 processor)
- Sixteen 10/100/1000BASE-T Copper (1 to 16)
- Sixteen 1 GigE SFP (17 - 28, S1, S2, VW1, VW2) (S1 and S2 are configured as sniffer interfaces, VW1 and VW2 are configured as virtual wire interfaces)
The following diagram also shows the XAUI and QSGMII port connections between the NP6 processor and the front panel interfaces.
The MGMT interface is not connected to the NP6 processor. Management traffic passes to the CPU over a dedicated management path that is separate from the data path. The HA interface is also not connected to the NP6 processors. To help provide better HA stability and resiliency, HA traffic uses a dedicated physical control path that provides HA control traffic separation from data traffic processing. The separation of management and HA traffic from data traffic keeps management and HA traffic from affecting the stability and performance of data traffic processing.
You can use the following get command to display the FortiGate 300E or 301E NP6 configuration. You can also use the diagnose npu np6 port-list
command to display this information.
