Modes in saving the configuration
z
Fast saving mode. This is the mode when you use the
save
command without the
safely
keyword.
The mode saves the file more quickly but is likely to lose the existing configuration file if the device
reboots or the power fails during the process.
z
Safe mode. This is the mode when you use the
save
command with the
safely
keyword. The mode
saves the file more slowly but can retain the configuration file in the device even if the device
reboots or the power fails during the process.
The fast saving mode is suitable for environments where power supply is stable. The safe mode,
however, is preferred in environments where stable power supply is unavailable or remote maintenance
is involved.

During the execution of the

main
] command, the startup configuration file to be
used at the next system startup may be lost if the device reboots or the power supply fails. In this
case, the device will boot with the null configuration, and after the device reboots, you need to
re-specify a startup configuration file for the next system startup (refer to
Specifying a Startup
Configuration File for the Next System Startup
).
Setting Configuration Rollback
Configuration rollback allows you to revert to a previous configuration state based on a specified
configuration file. The specified configuration file must be a valid
.cfg
file, namely, it can be generated
by using either the backup function (manually or automatically) or the
save
command, and even the
compatible configuration file of another device. You are recommended to use the configuration file that
