diagnose commands

You can use the CLI diagnose commands to gather diagnostic information that can be useful to Fortinet Customer Care when diagnosing any issues with your system. The commands are similar to the Linux commands used for debugging hardware, system, and IP networking issues.

The most important command for customers to know is diagnose debug report. This prepares a report you can give to your Fortinet support contact to assist in debugging an issue.

The following examples show the lists of diagnose commands:
