backup: Saves the configuration to the backup configuration file.
main: Saves the configuration to the main configuration file.
Description
Use the save command to save the current configuration to a configuration file in the Flash.
When you use this command to save the configuration file,
If the main and backup keywords are not specified, the current configuration will be saved to the
main configuration file.
If the cfgfile argument is specified, but the file specified by it does not exist, the system will create
the file and then save the current configuration to it. The file attribute is neither main nor backup.
If the cfgfile argument is specified and the file specified by it exists, the system will save the current
configuration to the specified file. The file attribute is the original attribute of the file.
If the cfgfile argument is not specified, the system will save the current configuration to the
configuration file used for this startup. If the switch starts up without loading the configuration file,
the system will save the current configuration with the default name (config.cfg) in the root
directory.
The system supports two modes for saving the current configuration file.
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 switch
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 Flash even if the switch
reboots or the power fails during the process.
When you use the save safely command to save the configuration file, if the switch reboots or the
power fails during the saving process, the switch initializes itself in the following two conditions when it
starts up next time:
If a configuration file with the extension .cfg exists in the Flash, the switch uses the configuration
file to initialize itself when it starts up next time.
If there is no .cfg configuration file in the Flash, but there is a configuration file with the
extension .cfgbak (backup configuration file containing the original configuration information)
or/and a configuration file with the extension .cfgtmp (temporary configuration file containing the
current configuration information) in the Flash, you can change the extension .cfgbak or .cfgtmp
to .cfg using the rename command. The switch will use the renamed configuration file to initialize
itself when it starts up next time.
For details of the rename command, refer to the File System Management part of the manual.
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.
If you use the save command after a fabric is formed on the switch, the units in the fabric save their
own startup configuration files automatically.
The extension name of the configuration file must be .cfg.
