Checking the modem status

You can use the CLI to troubleshoot a modem that is not working properly, or troubleshoot a FortiGate that does not detect the modem.

To diagnose modem issues in the CLI:

diagnose sys modem {cmd | com | detect | history | external-modem | query| reset}

You should always run the following command after you connect a USB modem to FortiGate:

diagnose sys modem detect

Use the following command to view the modem's configuration, vendor and custom product identification number:

get system modem

Use the following commands to resolve connectivity issues:

  • diagnose debug enable: Activates the debug on the console
  • diagnose debug application modemd: Dumps communication between the modem and the unit.
  • diagnose debug application ppp: Dumps the PPP negotiating messages.
  • execute modem dial: Displays modem debug output.

The modem diagnose output should not contain errors when initializing. You should also verify the number used to dial into your ISP.
