The sample output information in this manual was created on the WX3024. The output information on
your device may vary.

Introduction to Configuration File

A configuration file records and stores user configurations performed to the device. It also enables
users to check device configurations easily.
Types of configuration
The configuration of a device falls into two types:
Saved configuration, a configuration file used for initialization. If this file does not exist, the device
starts up without loading any configuration file.
Current configuration, which refers to the user's configuration during the operation of a device. This
configuration is stored in dynamic random-access memory (DRAM). It is removed when rebooting.
Format of configuration file
Configuration files are saved as text files for ease of reading. They:
Save configuration in the form of commands.
Save only non-default configuration settings.
The commands are grouped into sections by command view. The commands that are of the same
command view are grouped into one section. Sections are separated by comment lines. (A line is a
comment line if it starts with the character "#".)
The sections are listed in this order: system configuration section, logical interface configuration
section, physical port configuration section, routing protocol configuration section, user interface
configuration, and so on.
End with a return.
The operating interface provided by the configuration file management function is user-friendly. With it,
you can easily manage your configuration files.
Main/backup attribute of the configuration file
Main and backup indicate the main and backup attribute of the configuration file respectively. A main
configuration file and a backup configuration file can coexist on the device. As such, when the main
configuration file is missing or damaged, the backup file can be used instead. This increases the safety
and reliability of the file system compared with the device that only support one configuration file. You
