Configuration File Overview
A configuration file saves the device configurations in command lines in text format. You can view
configuration information conveniently through configuration files.
Types of Configuration
The configuration of a device falls into two types:
z
Startup configuration, a configuration file used for initialization when the device boots. If this file
does not exist, the system boots using null configuration, that is, using the default parameters.
z
Current configuration, which refers to the currently running configuration of the system. The current
configuration may include the startup configuration if the startup configuration is not modified
during system operation, and it also includes the new configuration added during the system
operation. The current configuration is stored in the temporary storage medium of the device, and
will be removed when the device reboots if not saved.

interface view, routing protocol view, and user interface view. Sections are separated with one or
multiple blank lines or comment lines that start with a pound sign #.
