NMI switch and NMI reset commands
When working with Fortinet Support to troubleshoot problems with your FortiGate-6000F you can use the front panel non-maskable interrupt (NMI) switch to assist with troubleshooting. Pressing this switch causes the software to dump management board registers/backtraces to the console. After the data is dumped the management board reboots. While the management board is rebooting, traffic is temporarily blocked. The management board should restart normally and traffic can resume once the management board is up and running.
You can use the following command to dump registers/backtraces of one or more FPCs to the console. After the data is dumped, the FPCs reboot. While the FPCs are rebooting, traffic is distributed to the remaining FPCs. The FPCs should restart normally and traffic can resume once they are up and running.
execute load-balance slot nmi-reset <slot-number(s)>
<slot-number(s)> can be one or more FPC slot numbers or slot number ranges with no space and separated by commas. For example:
execute load-balance slot nmi-reset 1,3-4
