Configuration Task List; Configuring Parameters For Saving The Current Running Configuration - H3C S5120-SI Series Operation Manual

The application environment has changed and the device has to run in a configuration state based
on a previous configuration file without being rebooted.
Set configuration rollback following these steps:
1) Specify the filename prefix and path for saving the current configuration.
2) Save the current running configuration with the specified filename (filename prefix + serial number)
to the specified path. The current running configuration can be saved in two ways: the system
saves the current running configuration at a specified interval; or you can save the current running
configuration as needed.
3) Roll back the current running configuration to the configuration state based on a saved
configuration file. When the related command is entered, the system first compares and then
processes the differences between the current running configuration and the specified
replacement configuration file:
The rollback operation does not execute the commands that are the same in the replacement
configuration file and in the current configuration file.
The rollback operation removes the commands only present in the current configuration file but not
in the replacement configuration file; namely, the corresponding undo form commands are
executed.
The rollback operation executes the commands only present in the replacement configuration file
but not in the current configuration file.
The rollback operation removes the commands that are different in the replacement configuration
file and in the current configuration file, and then executes them according to the replacement
configuration file.

Configuring Parameters for Saving the Current Running Configuration

Before the current running configuration is saved manually or automatically, the file path and filename
prefix must be configured. After that, the system saves the current running configuration with the
specified filename (filename prefix_serial number.cfg) to the specified path. The filename of a saved
configuration file is like 20080620archive_1.cfg, or 20080620archive_2.cfg. The saved configuration
files are numbered automatically, from 1 to 1,000 (with increment of 1). If the serial number reaches
1,000, it restarts from 1. If you change the path or filename prefix, or reboot the device, the saved file
serial number restarts from 1, and the system recounts the saved configuration files. If you change the
path of the saved configuration files, the files in the original path become common configuration files,
and are not processed as saved configuration files.
