z  When saving the current configuration, you can specify the file to be a main or backup or normal 
configuration file. 
z  When removing a configuration file from a switch, you can specify to remove the main or backup 
configuration file. Or, if it is a file having both main and backup attribute, you can specify to erase 
the main or backup attribute of the file. 
z  When setting the configuration file for next startup, you can specify to use the main or backup 
configuration file. 
Startup with the configuration file 
When booting, the system chooses the configuration files following the rules below: 
1)  If the main configuration file exists, the switch initializes with this configuration. 
2)  If the main configuration file does not exist but the backup configuration file exists, the switch 
initializes with the backup configuration. 
3)  If neither the main nor the backup configuration file exists, but the default configuration file 
config.def exists, the switch initializes with the default configuration file; if the default configuration 
file does not exist, the switch starts up without loading the configuration file.

Saving the Current Configuration 
You can modify the configuration on your switch at the command line interface (CLI). To use the 
modified configuration for your subsequent startups, you must save it (using the save command) as a 
configuration file. 
Use the following command to save current configuration:

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 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 switch even if the switch 
reboots or the power fails during the process.
