FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
Solution To check the port mapping to NPU in FortiOS:
#diagnose npu <npx> port-list
Where the NPX is the NPU type available for the specific model, it can be find out by
#diagnose npu ?
Example:
# diagnose npu np6lite port-list
Chip XAUI Ports Max Cross-chip Speed offloading ------ ---- ------- ----- ---------- np6lite_0 2 port9 1000M NO 1 port10 1000M NO 4 port11 1000M NO 3 port12 1000M NO 6 port13 1000M NO 5 port14 1000M NO 9 port15 1000M NO 10 port16 1000M NO 8 port17 1000M NO 7 port18 1000M NO np6lite_1 2 wan1 1000M NO 1 wan2 1000M NO 4 port1 1000M NO 3 port2 1000M NO 6 port3 1000M NO 5 port4 1000M NO 8 port5 1000M NO 7 port6 1000M NO 10 port7 1000M NO 9 port8 1000M NO
Above shows different port mapped to different NPU. For model with multiple NPU and does not have switch fabric, it will not support link aggregation for port mapped to different NPU. To check if the model support switch fabric, crosscheck the hardware acceleration document which can be found in Fortinet online documents.
