MANAGING SYSTEM FILES
The configuration file structure consists of the following configuration
files:
■ Startup Configuration File — Contains the commands required to
reconfigure the device to the same settings as when the device is
powered down or rebooted. The Startup file is created by copying the
configuration commands from the Running Configuration file or by
downloading the configuration file from via TFTP or HTTP.
■ Running Configuration File — Contains all configuration file
commands, as well as all commands entered during the current
session. After the device is powered down or rebooted, all commands
stored in the Running Configuration file are lost. During the startup
process, all commands in the Startup file are copied to the Running
Configuration File and applied to the device. During the session, all
new commands entered are added to the commands existing in the
Running Configuration file. Commands are not overwritten. To
update the Startup file, before powering down the device, the
Running Configuration file must be copied to the Startup
Configuration file by clicking on the Save Configuration button. The
next time the device is restarted, the commands are copied back into
the Running Configuration file from the Startup Configuration file.
■ Image files — Software upgrades are used when a new version file is
downloaded. The file is checked for the right format, and that it is
complete. After a successful download, the new version is marked,
and is used after the device is reset.
Backup and restore of the configuration files are always done from and to
the Startup Config file.
