Clearing the Startup Configuration File
To clear the contents of your startup configuration, use the erase nvram: or the erase startup-config
privileged EXEC command.
You cannot restore the startup configuration file after it has been deleted.
Caution
Deleting a Stored Configuration File
To delete a saved configuration from flash memory, use the delete flash:filename privileged EXEC
command. Depending on the setting of the file prompt global configuration command, you might be
prompted for confirmation before you delete a file. By default, the switch prompts for confirmation on
destructive file operations. For more information about the file prompt command, see the Cisco IOS
Command Reference for Release 12.2.
Caution
You cannot restore a file after it has been deleted.
Replacing and Rolling Back Configurations
The configuration replacement and rollback feature replaces the running configuration with any saved
Cisco IOS configuration file. You can use the rollback function to roll back to a previous configuration.

Archiving a Configuration
The configuration archive provides a mechanism to store, organize, and manage an archive of
configuration files. The configure replace privileged EXEC command increases the configuration
rollback capability. As an alternative, you can save copies of the running configuration by using the copy
running-config destination-url privileged EXEC command, storing the replacement file either locally
or remotely. However, this method lacks any automated file management. The configuration replacement
and rollback feature can automatically save copies of the running configuration to the configuration
archive.
