Configuration file management
The device provides the configuration file management function. You can manage configuration files on
the user-friendly command line interface (CLI).
This chapter includes these sections:
• Configuration file overview
• Saving the running configuration
• Setting configuration rollback
• Specifying a startup configuration file to be used at the next system startup
• Backing up the startup configuration file
• Deleting a startup configuration file to be used at the next startup
• Restoring a startup configuration file
• Displaying and maintaining a configuration file
Configuration file overview
A configuration file contains a set of commands. You can save the current configuration to a
configuration file so that the configuration can take effect after a device reboot. In addition, you can view
the configuration information, or upload or download the configuration file to or from another device.
Types of configuration
The device maintains the following types of configurations: factory defaults, startup configuration, and
running configuration.
Factory defaults
Devices are shipped with some basic settings, which are called factory defaults. These default settings
ensure that a device can start up and run normally when it has no configuration file or the configuration
file is damaged.
To view the factory defaults of the device, you can use the display default-configuration command.
Startup configuration
Use startup configuration for initialization when the device boots. If this file does not exist, the system
boots using the factory defaults.
You can view the startup configuration in either of the following ways:
• Use the display startup command to view the currently using startup configuration file, and use the
more command to view the content of the configuration file.
• After the reboot of the device and before configuring the device, use the display
current-configuration command to view the startup configuration.
Running configuration
The currently running configuration may include the startup configuration if the startup configuration has
not been modified during system operation. It also includes any new configurations added during the
