Appendix 1 Working with the Cisco IOS File System, Configuration Files, and Software Images
Working with Configuration Files
This example shows how to store a startup configuration file on a server:
Switch#
configure terminal
Switch(config)#
ip rcmd remote-username netadmin2
Switch(config)#
end
Switch#
copy nvram:startup-config rcp:
Remote host[]?
172.16.101.101
Name of configuration file to write [switch2-confg]?
Write file switch2-confg on host 172.16.101.101?[confirm]
![OK]
Clearing Configuration Information
You can clear the configuration information from the startup configuration. If you reboot the switch with
no startup configuration, the switch enters the setup program so that you can reconfigure the switch with
all new settings.
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.
Caution
You cannot restore the startup configuration file after it has been deleted.
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 12.4
.
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.
