     diagnose hardware deviceinfo np6xlite  
     diagnose system memory status  

2. ​​Post-Update Verification​​:

   • Monitor threat detection metrics:

     diagnose test application ipsmonitor 99  
     get system fortiguard status  

   • Confirm IoT device classifications:

     diagnose sys auto-iot list
