Configuration file management
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 switch reboot. In addition, you can
conveniently view the configuration information, or upload and download the configuration file to/from
another switch to configure switches in batches.
Types of configuration
The switch maintains the following types of configurations: factory defaults, startup configuration, and
running configuration.
Factory defaults
Switches are shipped with some basic settings, which are called factory defaults. These default settings
ensure that a switch can start up and run normally when it has no configuration file or the configuration
file is damaged.
Startup configuration
Use startup configuration for initialization when the switch boots. If this file does not exist, the system
boots using null configuration. Null configuration is the factory default configuration, which may differ
from the default settings for commands. The factory default configuration may vary with switch models.
View the startup configuration using either of the following methods:
• Use the display startup command to view the currently using configuration file, and use the more
command to view the content of the configuration file.
• After the reboot of the switch and before configuring the switch, use the display
current-configuration command to view the startup configuration.
Running configuration
The running configuration is stored in the temporary storage media of the switch, and will be removed if
not saved when the switch reboots.
Use the display current-configuration command to view the current validated configuration of the switch.
Format and content of a configuration file
A configuration file is saved as a text file; the following rules apply:
• Only non-default configuration settings are saved.
• Commands in a configuration file are listed in sections by views, usually in the order of system view,
interface view, routing protocol view, and user interface view. Sections are separated with one or
multiple blank lines or comment lines that start with a pound sign #.
• A configuration file ends with a return.
