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. 

 

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:

startup (distributed device):
