Erasing The Startup Configuration File - 3Com WX3000 Series Operation Manual

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.
The configuration file to be used for next startup may be lost if the device reboots or the power fails
during the configuration file saving process. In this case, the device reboots without loading any
configuration file. After the device reboots, you need to specify a configuration file for the next startup.
Refer to Specifying a Configuration File for Next Startup
Three attributes of the configuration file
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 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.
It is recommended to adopt the fast saving mode in the conditions of stable power and adopt the
safe mode in the conditions of unstable power or remote maintenance.
The extension name of the configuration file must be .cfg.
