CAUTION:
Do not unplug and plug a card during configuration rollback (that is, the system is executing the
configuration replace file command). In addition, configuration rollback may fail if one of the following
situations is present (if a command cannot be rolled back, the system skips it and processes the next one):
• The complete undo form of a command is not supported, namely, you cannot get the actual undo form
of the command by simply putting the keyword undo in front of the command, so the complete undo
form of the command cannot be recognized by the device.
• The configuration cannot be removed, such as hardware-related commands
• Commands in different views are dependent on each other
• If the replacement configuration file is not a complete file generated by using the save or archive
configuration command, or the file is copied from a different type of device, the configuration cannot be
rolled back. Ensure that the replacement configuration file is correct and compatible with the current
device.
• The configuration file specified with the configuration replace file filename command can only be a
configuration file in simple text. Otherwise, errors may occur in configuration rollback.
Specifying a Startup Configuration File to Be Used
at the Next System Startup
To specify a startup configuration file to be used at the next system startup:
• Use the save command. If you save the running configuration to the specified configuration file in
the interactive mode, the system automatically sets the file as the startup configuration file to be used
at the next system startup.
• Use the command dedicated to specify a startup configuration file to be used at the next startup,
which is described in the following table:
Follow the step below to specify a startup configuration file to be used at the next startup:

Available in user view
CAUTION:
A configuration file must use .cfg as its extension name and the startup configuration file must be saved on
the first partition of the storage medium.
Backing Up the Startup Configuration File
The backup function allows you to copy the startup configuration file to be used at the next startup from
the device to the TFTP server.
Follow the step below to back up the startup configuration file to be used at the next startup:
