Usage guidelines
To replace the running configuration with the configuration in a configuration file without rebooting the
device, use the configuration rollback function. This function helps you revert to a previous configuration
state or adapt the running configuration to different network environments.
To avoid rollback failure:
• Use the configuration archive function or the save command on the current device to create the
replacement configuration file.
• If the configuration file is not created on the current device, make sure the configuration file content
format is fully compatible with the current device.
• The replacement configuration file is not encrypted.
Examples
# Replace the running configuration with the configuration in the my_archive_1.cfg configuration file.
<Sysname> system-view
[Sysname] configuration replace file my_archive_1.cfg
Current configuration will be lost, save current configuration? [Y/N]:n
