At a moment, there are at most one main startup configuration file and one backup startup configuration
file. You can specify neither of the two files (displayed as NULL), or specify the two files as the same
configuration file.
You can specify the main and backup startup configuration files for the next boot of the device in the
following two methods:
z
Specify them when saving the current configuration. For detailed configuration, refer to
Saving the
Current Configuration
.
z
Specify them when specifying the startup configuration file for the next system startup. For detailed
configuration, refer to
Specifying a Startup Configuration File for the Next System Startup
.
Startup with the configuration file
The device takes the following steps when it boots:
1) If the main startup configuration file exists, the device initializes with this configuration file.
2) If the main startup configuration file does not exist but the backup startup configuration file exists,
the device initializes with the backup startup configuration file.
3) If neither the main nor the backup startup configuration file exists, the device will boot with null
configuration (boot with null configuration means to boot with the factory default configuration).
Saving the Current Configuration
Introduction
You can modify the current configuration on your device using command line interface. However, the
current configuration is temporary. To make the modified configuration take effect at the next boot of the
device, you must save the current configuration to the startup configuration file before the device
reboots.
Complete these tasks to save the current configuration:

After the configuration file auto-save function is enabled, when you save the current configuration
by executing the

or executing the

command and then pressing
Enter
, the master and a slave will automatically save the current
configuration to the specified configuration file, and use the file as the configuration file for the next
startup, thus keeping the consistency of the configuration files on the master and the slave.

If the configuration file auto-save function is not enabled, when you save the current configuration
by executing the

or executing the

command and then pressing

, only the master will automatically save the current
configuration to the specified configuration file, and use the file as the configuration file for the next
startup; the slaves will neither save the configuration file nor configure the file for the next startup.
Follow these steps to configure the configuration file auto-save function:
