Secure Firewall Management Center Command Line Reference

This reference explains the command line interface (CLI) for the Secure Firewall Management Center.


Note
For Secure Firewall Threat Defense, see the Cisco Secure Firewall Threat Defense Command Reference.

About the Secure Firewall Management Center CLI

When you use SSH to log into the management center, you access the CLI. Although we strongly discourage it, you can then access the Linux shell using the expert command .


Caution

We strongly recommend that you do not access the Linux shell unless directed by Cisco TAC or explicit instructions in the Firepower user documentation.


Caution

Users with Linux shell access can obtain root privileges, which can present a security risk. For system security reasons, we strongly recommend:

  • If you establish external authentication, make sure that you restrict the list of users with Linux shell access appropriately.

  • Do not establish Linux shell users in addition to the pre-defined admin user.

You can use the commands described in this appendix to view and troubleshoot your Secure Firewall Management Center, as well as perform limited configuration operations.

Secure Firewall Management Center CLI Modes

The CLI encompasses four modes. The default mode, CLI Management, includes commands for navigating within the CLI itself. The remaining modes contain commands addressing three different areas of Secure Firewall Management Center functionality; the commands within these modes begin with the mode name: system, show, or configure.

When you enter a mode, the CLI prompt changes to reflect the current mode. For example, to display version information about system components, you can enter the full command at the standard CLI prompt:

> show version

If you have previously entered show mode, you can enter the command without the show keyword at the show mode CLI prompt:

show> version

Secure Firewall Management Center CLI Management Commands

The CLI management commands provide the ability to interact with the CLI. These commands do not affect the operation of the device.

exit

Moves the CLI context up to the next highest CLI context level. Issuing this command from the default mode logs the user out of the current CLI session.

Syntax


exit

Example


system> exit
>

expert

Invokes the Linux shell.

Syntax


expert

Example


> expert

? (question mark)

Displays context-sensitive help for CLI commands and parameters. Use the question mark (?) command as follows:

  • To display help for the commands that are available within the current CLI context, enter a question mark (?) at the command prompt.

  • To display a list of the available commands that start with a particular character set, enter the abbreviated command immediately followed by a question mark (?).

  • To display help for a command’s legal arguments, enter a question mark (?) in place of an argument at the command prompt.

Note that the question mark (?) is not echoed back to the console.

Syntax


?
abbreviated_command ?
command [arguments] ?

Example


> ?

Secure Firewall Management Center CLI Show Commands

Show commands provide information about the state of the appliance. These commands do not change the operational mode of the appliance and running them has minimal impact on system operation.

version

Syntax

Displays the product version and build. 


show version

Example


> show version

Secure Firewall Management Center CLI Configuration Commands

The configuration commands enable the user to configure and manage the system. These commands affect system operation.

password

Syntax

Allows the current CLI user to change their password.


Caution

For system security reasons, we strongly recommend that you do not establish Linux shell users in addition to the pre-defined admin on any appliance.


Note

The password command is not supported in export mode. To reset password of an admin user on a secure firewall system, see Learn more. If you use password command in expert mode to reset admin password, we recommend you to reconfigure the password using configure user admin password command. After you reconfigure the password, switch to expert mode and ensure that the password hash for admin user is same in /opt/cisco/config/db/sam.config and /etc/shadow files.

After issuing the command, the CLI prompts the user for their current (or old) password, then prompts the user to enter the new password twice. 


configure password

Example


> configure password
Changing password for admin.
(current) UNIX password: 
New UNIX password:
Retype new UNIX password:
passwd: password updated successfully

Secure Firewall Management Center CLI System Commands

The system commands enable the user to manage system-wide files and access control settings.
