NP6XLite processors
The NP6XLite is a new iteration of NP6 technology that supports more features than the standard NP6 processor. For example, the NP6XLite can offload AES128-GCM and AES256-GCM encryption for IPsec VPN traffic. The NP6XLite has slightly lower throughput (36Gbps) than the NP6 (40Gbps).
The NP6XLite includes 4x KR/USXGMII/QSGMII and 2x(1x) Reduced gigabit media-independent interface (RGMII) interfaces.
The NP6XLite is a component of the Fortinet SOC4. The SOC4 includes a CPU, the NP6XLite network processor, and the CP9XLite content processor that supports most CP9 functionality but with a lower capacity.
The SOC4 includes an integrated switch fabric (ISF) that connects all of the front panel network interfaces to the NP6XLite processor. The SOC4 ISF allows sessions passing between any FortiGate front panel interface pair to be offloaded by the NP6XLite processor. The SOC4 ISF also allows you to use the command config system virtual-switch to create a virtual hardware switch that can include any front panel interface connected to the SOC4.

Some FortiGate models, such as the FortiGate-200F and 201F include a SOC4 but only use the NP6XLite processor. FortiGate-200F and 201F CPU functionality is supplied by a separate CPU and CP9 functionality by two separate CP9 processors. See FortiGate 200F and 201F fast path architecture for more information.
