H3C S3100 Series Ethernet Switches Chapter 1 Configuration File Management
1-3
I. 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 quicker but is likely to lose the original
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 slower but can retain the original configuration
file in the device even if the device reboots or the power fails during the process.
Caution:
S3100 series Ethernet switches do not support the safe mode. When you are saving a
configuration file using the save safely command, if the device reboots or the power
fails during the saving process, the configuration file will be lost.
II. Three attributes of the configuration file
z 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.
z 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.
z Normal attribute. When you use the save cfgfile 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 dependent on the original attribute of the
file.
 Note:
The extension name of the configuration file must be .cfg.
