Running the TAC report
The Technical Assistance Center (TAC) report runs an exhaustive series of diagnostic commands. Some of the commands are only needed if you are using features, such as HA, VPN tunnels, or a modem. Fortinet support my ask you to use the report output to provide information about the current state of your FortiGate.
Due the amount of output generated, the report may take a few minutes to run. If you are logging CLI output to a file, you can run this command to familiarize yourself with the diagnostic commands.
To run the TAC report in the CLI:
execute tac report
