6.8 How to Get the ZyWALL’s Diagnostic File
This example shows you how to generate a file containing the ZyWALL’s configuration and
diagnostic information if you need to provide it to customer support for troubleshooting.
1 Go to the Maintenance > Diagnostics > Collect screen, click Collect Now.
2 After the process is done, the file information displays on the screen. Click Download to save the
file to your computer.
The ZyWALL uses the flash space to store diagnostic files. Once the flash is full, the ZyWALL stops
generating the file. If your ZyWALL’s flash is almost full, you can use a USB storage device.
Note: You can check the remaining flash space in the Dashboard or Maintenance >
Diagnostics > Packet Capture screen.
To save diagnostic files to a USB storage device, do the following before you collect a diagnostic file:
1 Insert the USB storage device to any USB port on your ZyWALL. In the Monitor > System Status
> USB Storage screen, make sure the USB device’s file system doesn’t display “unknown”.
