SonicWall console data can be useful to obtain vital information helpful for troubleshooting purposes.

This article describes capturing and saving the console screen output to a file using terminal applications such as Putty, Tera Term or SecureCRT.

Requirements:

A SonicWall UTM appliance.
The original SonicWall console cable. If you don't have this, please check How do I make a console cable for SonicWall firewall appliances?
For further assistance on this, please contact our Technical Support.
A computer with a Serial port or a USB to DB9 Adapter.

Resolution

Below two different guides showing the process using TeraTerm or SecureCRT as examples but you can choose your own application and follow the respective steps.

Launch Tera Term. Select COM1 (or COM2) in the New Connection window.
Use the following settings to communicate with the serial port connected to the appliance.
1. 115,200 baud
2. 8 data bits
3. no parity
