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,
z If the main and backup keywords are not specified, the current configuration will be saved to the
main configuration file.
z 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.
z 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.
z 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.
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 switch
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 Flash even if the switch
reboots or the power fails during the process.
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.
The extension name of the configuration file must be .cfg.
Examples
# Save the current configuration to 123.cfg as the main configuration file for the next startup.
<Sysname> save main
The configuration will be written to the device.
