• The replacement configuration file is not encrypted.
To roll back configuration:
Step Command
1. Enter system view. system-view
2. Perform configuration rollback. configuration replace file filename
The configuration rollback function might fail to reconfigure some commands in the running configuration
for one of the following reasons:
• A command cannot be undone, because prefixing the undo keyword to the command does not
result in a valid undo command. For example, if the undo form designed for the A [B] C command
is undo A C, the configuration rollback function cannot undo the A B C command, because the
system does not recognize the undo A B C command.
• A command (for example, a hardware-dependent command) cannot be deleted, overwritten, or
undone due to system restrictions.
• The commands in different views are dependent on each other.
• Commands or command settings that the device does not support cannot be added to the running
configuration.
• The rollback operation does not take effect on the enhanced IRF mode setting (the irf mode
enhanced command or its undo form). The enhanced mode setting in the current running
configuration continues to run after the rollback. For more information about the irf mode enhanced
or undo irf mode enhanced command, see IRF Command Reference.
Specifying a configuration file for the next startup
You can specify a .cfg configuration file as the startup configuration file to be used at the next startup
when you use the save command to save the running configuration.
Alternatively, perform the following task in user view to specify the next-startup configuration file:
Task Command Remarks
Specify the next-startup
configuration file.
startup saved-configuration cfgfile
In standalone mode, the setting
applies to both active MPU and
standby MPU.
In IRF mode, the setting applies to
all MPUs in the IRF fabric.
IMPORTANT:
The configuration file must use
the .cfg extension and be saved in
the root directory of the flash
memory or CF card.
If the storage medium has been
partitioned, save the file on the first
partition.
Do not save the startup
configuration file to a USB disk.
