7.1 System Startup Overview
When the router is powered on, system software starts and configuration files are loaded.
7.1.1 System Software
System software provides an operating system for the router. System software must be set up
correctly for the router to run properly and provide services.
The extension for the system software file is .cc. The file must be saved in the root directory of
the storage device.
7.1.2 Configuration Files and Current Configurations
When the router is running, current configurations differ from configuration files.
The concepts of configuration files and current configurations are as follows.
Concept Identifying Method
Configuration files Initial configurations: When
powered on, the router
retrieves configuration files
from a default save path to
initialize itself. If
configuration files do not
exist in the default save path,
the router uses default
initialization parameters.
l Run the display startup
command to view the
configuration files for the
current startup and next
startup on the router.
l Run the display saved-
configuration command
to view the configuration
file for the next startup on
the router.
Current configurations
Current configurations:
indicates the configurations
in effect on the router when it
is actually running.
Run the display current-
configuration command to
view current configurations
on the router.
You can use the command line interface to modify current router configurations. Use the save
command to save modified configurations to the configuration file on the default storage devices.
This configuration file will be used to initialize the router when the router is powered on next
time.
7.2 Managing Configuration Files
You can manage the configuration files for the current and next startup operations on the
router.
