Configuration: a series of command operations performed on the system to meet service requirements. These operations still take effect after the system restarts.
Configuration file: a file used to save configurations. You can use a configuration file to view configuration information. You can also upload a device's configuration file to other devices for batch management.
A configuration file saves command lines in a text format. (Non-default values of the command parameters are saved in the file.) Commands can be organized into a basic command view framework. The commands in the same command view can form a section. Empty or comment lines can be used to separate different sections. The line beginning with "#" is a comment line.
Configuration management: a function for managing configurations and configuration files using a series of commands.
A storage medium can save multiple configuration files. If the location of a device on the network changes, its configurations need to be modified. To avoid reconfiguring the device, specify a configuration file for the next startup. The device restarts with new configurations to adapt to its new environment.
Configuration management allows you to lock, preview, and discard configurations, save the configuration file used at the current startup, and set the configuration file to be loaded at the next startup of the system.
