From VyOS Wiki
A VyOS system has multiple configuration. There are three major types of configurations:
- Active or running configuration
- The active or running configuration is the system configuration that is loaded and currently being used by VyOS.
- Working configuration
- The working configuration is the configuration which is currently being modified in configuration mode. Changes made to the working configuration do not go into effect until the changes are committed with the commit command. At which time the working configuration will become the active or running configuration.
- Saved configuration
- A saved configuration is a configuration saved to a file using the save command. There can be multiple configuration files. The default or "boot" configuration is saved and loaded from the file config.boot.
