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 device initializes with this configuration.
2) If the main configuration file does not exist but the backup configuration file exists, the device
initializes with the backup configuration.
3) If neither the main nor the backup configuration file exists:
z For an S3100-SI Ethernet switch, the switch starts up without loading the configuration file;
z For an S3100-EI Ethernet switch, if 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

modified configuration for your subsequent startups, you must save it (using the save command) as a
configuration file.

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.
