How can I login to the appliance using the Command Line Interface (CLI)?

SonicWall UTM appliances provide support for command line interface (CLI) commands to monitor and manage the device.

NOTE: Only one session at a time can configure the SonicWall, whether the session is on the GUI or the CLI (serial console). For instance, if a CLI session goes to the config level, it will ask you if you want to preempt an administrator who is at config level in the GUI or CLI session.

The SonicWall CLI currently uses the administrator’s password to obtain access. SonicWall devices are shipped with a default password of password.

You may need to use the CLI for the following reasons:

• GUI is not accessible/freeze (hang)
• Configure BGP Protocol
• Apply some changes that can be made only by CLI
• Export some diagnostic files

1. Console connection:
   Step 1: Attach the included null modem cable to the appliance port marked CONSOLE. Attach the other end of the null modem cable to a serial port on the configuring computer.
   N.B. You may use an adapter DB9 Male to USB if you don't have any PC with the serial Port.
   
   
   
   
   When the connection is established, log in to the security appliance:

• At the User: prompt enter the Admin’s username. Only the admin user will be able to login from the CLI. The default Admin username is admin. The default can be changed.
• At the Password: prompt, enter the Admin’s password. If an invalid or mismatched username or password is entered, the CLI prompt will return to User:, and a “CLI administrator login denied due to bad credentials” error message will be logged. There is no lockout facility on the CLI.

Step 2: Launch any terminal emulation application that communicates with the serial port connected to the appliance (PuTTY, TeraTerm Pro, SecureCRT, HyperTerminal, etc.)

• Use these settings: 
• COM1
• 115,200 baud
• 8 data bits
• no parity
• stop bit
• no flow control

2. SSH on interface:
If SSH is enabled on the interface, you can use the PuTTY or any similar Terminal software to log in to the device. In some cases of high CPU utilization, even this will hang on you.
Then follow Step 2 from the above example to log in.
