Providing Supporting Elements
If the Fortinet Technology Assistance Center (TAC) needs to be contacted to help you with your issue, be prepared to provide the following information:
The firmware build version (use the get system status command)
A network topology diagram
A recent configuration file
Optionally, a recent debug log
Tell the support team what troubleshooting steps have already been performed and the results.
 
 
Do not provide the output from exec tac report unless Support requests it. The output from that command is very large and is not required in many cases.
For additional information about contacting Fortinet Customer Support, see “Technical Support Organization Overview”.
All of this is your troubleshooting plan.
