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 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, commands
stored in the Running Configuration file and not yet saved to the
Startup 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 already stored 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 to ensure
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 Configuration file.
