Description

FortiOS supports many more broadband devices than are currently detected natively. If a modem appears as undetected or unknown, there are a few steps to try in order to see if the modem can be detected.


Solution

1) Update latest known modem list.

Run the following command to update the latest list of known modems for FortiOS:

# exe update-modem
Updating Modem List. Done.


2) Check whether the modem is detected.

First plug the modem in to determine whether FortiOS is able to see it at all. The following command will determine whether FortiOS is able to detect a compatible modem.  The command may take a few minutes to run.

# diagnose system modem detect
modem is not attached.


If the 'modem is not attached' message is displayed it means that FortiOS is not aware of this modem vendor/model. In this case FortiOS support of custom modem definitions should allow non-working modems to work in most cases.

3) Determine the modems USB Vendor and Product ID's.

FortiOS requires the USB ID of an unknown modem in order to make it work. These values can be determined externally on a computer or by using the following command in FortiOS:

print gzfile /proc/bus/usb/devices

The above command will output similar to the following:

P:  Vendor=0f3d ProdID=68aa Rev= 0.06
S:  Manufacturer=Sierra Wireless, Incorporated
S:  Product=AirCard 320U


The vendor and product ID values can now be used to create a custom modem definition in FortiOS. These are configured as follows:

config system 3g-modem custom
    edit 1
        set vendor "Sierrawireless"
        set model "320U"
        set vendor-id 0f3d
        set product-id 68aa
    next
end
