original configuration file if the device reboots or the power fails during the
process.
■
Safe mode. This is the mode when you use the save command with the safely
keyword. The mode saves the file slower but can retain the original
configuration file in the device even if the device reboots or the power fails
during the process.

CAUTION: Device reboot or the power failure during configuration file saving may
result in loss of the configuration file for next startup. In this case, the device
should be started with empty configuration and after the device starts, you need
to re-specify a configuration file for next startup. Refer to
“Specifying a
Configuration File for Next Startup” on page 2102 for details.
Attributes of the configuration file when main/backup attribute is
supported
■
Main attribute. When you use the save [ safely ] [ main ] command to save
the current configuration, the configuration file you get has main attribute. If
this configuration file already exists and has backup attribute, the file will have
both main and backup attributes after execution of this command. If the
filename you entered is different from that existing in the system, this
command will erase its main attribute to allow only one main attribute
configuration file in the device.
■
Backup attribute. When you use the save [ safely ] backup command to save
the current configuration, the configuration file you get has backup attribute. If
this configuration file already exists and has main attribute, the file will have
both main and backup attributes after execution of this command. If the
filename you entered is different from that existing in the system, this
command will erase its backup attribute to allow only one backup attribute
configuration file in the device.
■
Normal attribute. When you use the save file-name command to save the
current configuration, the configuration file you get has normal attribute if it is
not an existing file. Otherwise, the attribute is the original attribute of the file.

Fast saving mode is suitable for environments where power supply is stable.
The safe mode, however, is preferred where stable power supply is unavailable
or remote maintenance is involved.
■
The extension name of the configuration file must be .cfg.
■
If you press <Enter> after entering the save command, you can save the
configuration file in an interactive way. In this way, you can use the default
path or enter a filename to specify a new path, but the suffix of the filename
must be “.cfg” and the path must be the path of the storage device on the
AMB (active main board).
