Technical Tip: Understanding NP7lite MAC MIB counters
| Description | This article describes key fields in the diagnose npu np7lite mac-mibs command. | ||||||||||||||||||||||||||||||||||||||||||
| Scope | All devices with NP7Lite chips. | ||||||||||||||||||||||||||||||||||||||||||
| Solution | This command diagnose npu np7lite mac-mibs displays MAC-layer interface-level packet statistics on FortiGate models equipped with NP7Lite network processors (a lower-capacity variant of the full NP7 processor, commonly found in mid-range models like the 90G/91G series with SOC5). These counters come from the MAC MIB (Management Information Base) and help troubleshoot interface-level issues, such as drops, errors, or performance at the hardware Ethernet MAC layer—before/after higher-level processing like firewall policies or NP offloading.
For effective log collection, it is best to collect this twice with one minute in between so it is possible to see what counters increase.
