Overview of Configuration File
A configuration file defines the configuration items required for the startup of the FW. You can save a configuration file on the device, modify and remove existing configuration files, and specify the configuration file for the FW to load upon each startup.
Current Configuration
The current configuration is the configuration currently takes effect, not the configuration file. A configuration file is generated only after you save the current configuration.
Configuration File
The configuration file is saved as a .txt file, and the requirements on its content are as follows:
The configuration file is saved in commands.
Only non-default parameters are saved. You can find the default value of each parameter in relevant chapters of this document.
Commands are organized by views. The commands available in the same view are listed together to form a section, and adjacent sections are separated by a blank line or comment line which starts with a number sign in a pair of square brackets ([#]). The number of blank lines or comment lines can be one or more.
Sections are usually arranged in the order from global configuration, physical interface configuration, logical interface configuration, to routing protocol configuration.
In a configuration file, the command that can be identified by the system must be a string of no more than 510 characters. Directly modifying the configuration file may cause certain commands in the configuration file to have more than 510 characters. Therefore, perform the operation with caution.
Concepts related to the configuration file are the configuration file for this startup, configuration file for the next startup, and configuration file for disaster recovery.
