In order to aid the support engineer`s investigation into the root cause of a customer reported issue, a few files are required from the Dell SonicWall UTM firewall. Below is a list of files which would be needed to troubleshoot and validate the probable causes of the issue:
1. Tech Support Report (TSR).
2. Configuration Settings (exp extension/cli).
3. Firewall Logs (CSV or TXT format).
4. Trace logs(Current, Last, All).
5. Packet Capture(Better with both Html and Libpcap).
This article will demonstrate how to export technical support files from the firewall command line interface(CLI) using SSH session in three operation systems, which are Windows, Linux and MacOS.
To export technical files from CLI using SSH, firstly enable the SSH management on the firewall:
1. Login to the SonicWall Management Interface.
2. Select Network | Interfaces.
3. Click the Edit icon for an interface (e.g. WAN / X1 interface)
4. Select SSH in the supported Management protocol(s) section.
You will also need an available FTP server.

Step 7. To export the configuration settings, issue the command "export current-config exp ftp ftp://sonicwall:firstname.lastname@example.org/3600conf.exp" for the import purpose, or issue the command "export current-config cli ftp ftp://sonicwall:email@example.com/3600conf" for configuration review purpose.
Step 8. To export the packet capture file, issue the command "export capture html ftp ftp://sonicwall:firstname.lastname@example.org/net.html", or "export capture libpcap ftp ftp://sonicwall:email@example.com/net.pcap".

STEP 10. Then issue the command "show log view", "diag show trace current", "diag show trace last" and "diag show trace". And all the returns will be saved in the session log file.
To export technical files from CLI using SSH on Linux and MacOS , is quite same with the CLI commands part. The difference is about how to connect to the firewall via SSH and how to save the session log.
Step 1. Navigate to Applications | System Tool | Terminal and click, or on the desktop right click then chose "Open In Terminal", and then will use the command line.
