Description

 

This article provides some basic steps to troubleshoot FortiExtender related problems.

 

Scope

 

FortiExtender.


Solution

 

  • The modem that is going to be used should be listed in the FortiOS and FortiExtender OS Compatibility Matrices. The compatibility matrix can also be obtained via the FortiGate GUI: under System -> Network -> FortiExtender -> Configure Settings and then select Supported Modems. This list can be updated using the Update Now button.

  • Make sure the modem is able to connect to the internet on a laptop in the same location the FortiExtender is located.

  • Make sure that CAPWAP is enabled on the interface connected to the FortiExtender, or use “Dedicated to Extension Device” to dedicate the interface to the FortiExtender.

  • Check the extender status by using the command:

 

get extender sys-info <FXTserial>

 

  • Get the detailed modem status of the extender:

 

get extender modem-status <FXTserial>

 

  • Enable extender logging and debugging, collect information for about 5 minutes:

 

diagnose debug disable
diagnose debug reset
diagnose debug application extender -1
diagnose debug enable

 

  • Disable extender logging and debugging as below :

 

diagnose debug disable
diagnose debug reset

  • To execute AT commands on FortiExtender:

 

diagnose extender atcmd <command> <Marker> <FXTserial>


The <Marker> specifies the string used to specify the '?' in the command, as the FortiGate CLI does not accept the '?'. The Marker string pattern is replaced with "?" in the at command string in the CLI backend.

Some examples:

AT+CPIN >> To check SIM status
AT+CSQ >> To check signal quality

  • To control the FortiExtender:

 

execute extender <command> <FXTserial>


This commands can be used to execute the following:

 

  • delete-fortiextender-image: Delete FortiExtender images.

  • dial: Force FortiExtender to dial.

  • hangup: Force FortiExtender to hang up.

  • list-fortiextender-image: List FortiExtender images.

  • push-fortiextender-image: Push FortiExtender image to a managed FortiExtender.

  • reset-fortiextender: Restart managed FortiExtender.

  • restart-fortiextender-daemon: Restart FortiExtender AC daemon.

  • upload-fortiextender-image: Upload FortiExtender image.
