Set configuration rollback

Required
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):
z 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.
z The configuration cannot be removed, such as hardware-related commands
z Commands in different views are dependent on each other
z 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.
Specifying a Startup Configuration File for the Next System Startup
A startup configuration file is the configuration file to be used at the next system startup. You can
specify a configuration file as the startup configuration file to be used at the next system startup in the
following two ways:
z Use the save command. If you save the current configuration to the specified configuration file in
the interactive mode, the system automatically sets the file as the configuration file to be used at
the next system startup (for a device supporting main/backup startup configuration file, the system
sets the file as the main startup configuration file to be used at the next system startup).
z Use the command dedicated to specify a startup configuration file, which is described in the
following table:
