Chapter 2 Configuration
Parameter
Boot Mode
Auto-save
Meaning
The settings file is read from a USB device when booting.
When the boot settings are set to read from USB, they are read from
the "default.cfg" file on the USB device. If there is no "default.cfg"
file on the USB device, the configuration file is read from the switch
itself.
When the settings are changed while a USB device is inserted in the
device, "default.cfg" is created on the USB device, and synchronized
with the settings on the product. The latest settings file is always
saved to "default.cfg" on the USB device.
"default.cfg" under the root directory of the USB device is loaded
upon booting.
A backup of the configuration file is automatically saved to the USB
device when the configuration is changed.
If enabled, the settings file is automatically saved to "default.cfg"
and "yyyymmdd.cfg" on the USB device whenever configuration
changes are made.
The latest version is always saved to "default.cfg", and the version
before the latest settings file is saved to "yyyymmdd.cfg".
default.cfg:
The latest settings file is synchronized with the product.
yyyymmdd.cfg:
This indicates the date set on the switch. The settings file from
before the change in settings is saved as a backup.
Example:
If the settings are changed on October 1, 2012 while Auto-save is
enabled, the settings file for after the change in settings is saved to
the USB device as "default.cfg" and the settings file from before the
change in settings is saved as "20121001.cfg" as a backup.
If several changes are made to the settings file on the same day,
"yyyymmdd.cfg" is overwritten.
"default.cfg" and "yyyymmdd.cfg" are saved to the root directory of
the USB device.
