Creating Text Configuration Files Offline

This guide describes how to use the CLI to configure the security appliance; when you save commands,
the changes are written to a text file. Instead of using the CLI, however, you can edit a text file directly
on your PC and paste a configuration at the configuration mode command-line prompt in its entirety, or
line by line. Alternatively, you can download a text file to the security appliance internal Flash memory.
See
the configuration file to the security appliance.

To view the running configuration of a specific command, enter the following command:
hostname# show running-config command
To view the startup configuration, enter the following command:
hostname# show startup-config
To clear all the configuration for a specified command, enter the following command:
hostname(config)# clear configure configurationcommand [ level2configurationcommand ]
This command clears all the current configuration for the specified configuration command. If you
only want to clear the configuration for a specific version of the command, you can enter a value for
level2configurationcommand.
For example, to clear the configuration for all aaa commands, enter the following command:
hostname(config)# clear configure aaa
To clear the configuration for only aaa authentication commands, enter the following command:
hostname(config)# clear configure aaa authentication
To disable the specific parameters or options of a command, enter the following command:
hostname(config)# no configurationcommand [ level2configurationcommand ] qualifier
In this case, you use the no command to remove the specific configuration identified by qualifier.
For example, to remove a specific nat command, enter enough of the command to identify it
uniquely as follows:
hostname(config)# no nat (inside) 1
To erase the startup configuration, enter the following command:
hostname(config)# write erase
To erase the running configuration, enter the following command:
hostname(config)# clear configure all
In multiple context mode, if you enter clear configure all from the system configuration, you
also remove all contexts and stop them from running.
