Configuration File
Overview
The operating interface provided by the configuration file management function is
user-friendly. With it, you can easily manage your configuration files.
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 default parameters are used.
■
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 the device is 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.
■
List commands in sections by view in this view order: system, interface, routing
protocol, and so on. Sections are separated with one or multiple blank lines or
comment lines that start with a pound sign (#).
■
End with a return.
