Managing the Configuration
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
Note In multiple context mode, if you enter clear configure all from the system configuration, you
also remove all contexts and stop them from running.
Creating Text Configuration Files Offline
This guide describes how to use the CLI to configure the FWSM; 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 FWSM internal Flash memory. See
Chapter 24,
“Managing Software, Licenses, and Configurations,” for information on downloading the configuration
file to the FWSM.
In most cases, commands described in this guide are preceded by a CLI prompt. The prompt in the
following example is “hostname(config)#”:
hostname(config)# context a
In the text configuration file you are not prompted to enter commands, so the prompt is omitted as
follows:
context a
For additional information about formatting the file, see Appendix C, “Using the Command-Line
Interface.”
