Introduction to
Configuration File
Configuration file records and stores user configurations performed to a switch. It
also enables users to check switch configurations easily.
Upon powered on, a switch loads the configuration file known as
saved-configuration file, which resides in the Flash, for initialization. If the Flash
contains no configuration file, the system initializes using the default settings.
Comparing to saved-configuration file, the configuration file which is currently
adopted by a switch is known as the current-configuration.
A configuration file conforms to the following conventions:
■
The content of a configuration files is a series of commands.
■
Only the non-default configuration parameters are saved.
■
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 empty lines or 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, and so on.
■
A configuration file ends with a “return”.
