Overview Configuration File Management

Configuration file management is a function that is used to manage device configuration files. Through the command line interface provided by the device, users can easily manage configuration files. If the device needs to automatically load the current configuration of users after restart, the current configuration commands must be saved into the configuration file before the device restarts. Users can upload configuration files to or download configuration files from another device through FTP or TFTP, realizing batch device configuration. The device configuration is categorized into the following two types:

Startup configuration:

When the device starts, it loads the startup configuration file with the name "startup" by default, and it completes the initialization configuration of the device. This configuration is called startup configuration. Here the device has two startup configuration files, one is the default startup configuration file, and the other is the backup startup configuration file. When the device starts, if the default startup configuration file does not exists, the system copies the backup startup configuration file to the location of the default startup configuration file and loads this startup configuration file.

Current configuration:

Current configuration is a set of commands that take effect currently. It consists of startup configuration and the configuration that is added or modified by the user after startup. The current configuration is saved in the memory database. If the current configuration is not saved into the startup configuration file, the configuration information gets lost after the device restarts.

The following describes the contents and formats of the configuration files:

• Configuration files are saved in the file system in the form of text files.
• The contents of the configuration files are saved in the form of configuration commands, and only non-default configuration is saved.
• Configuration files are organized based on command modes. All commands in one command mode are organized together to form a paragraph.
• Paragraphs are organized according to a certain rule: system configuration mode, interface configuration mode, and configuration modes of different protocols.
• Commands are organized according to their relations. The related commands form a group, and different groups are separated by blank lines.
