Manually archiving the running configuration
To save system resources, disable automatic configuration archiving and manually archive the
configuration if the configuration will not be changed very often. You can also manually archive
configuration before performing complicated configuration tasks. Then, you can use the archive for
configuration recovery if the configuration attempt fails.
Make sure you have set an archive path and file name prefix before performing this task.
Perform the following task in user view:
Task Command
Manually archive the running configuration.

Rolling back configuration
To avoid a rollback failure, follow these guidelines:
• Make sure the replacement configuration file is created by using the configuration archive
function or the save command on the local device.
• If the configuration file is not created on the local device, make sure the command lines in the
configuration file are fully compatible with the local device.
• The replacement configuration file is not encrypted.
To perform a configuration rollback:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Roll the running
configuration back to the
configuration defined by a
configuration file.
configuration replace file
filename
The specified configuration file
must not be encrypted.
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.
This is 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.
Specifying a next-startup configuration file
CAUTION:
In an IRF fabric, use the undo startup saved-configuration command with caution. This command
can cause an IRF split after the IRF fabric or an IRF member reboots.
