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:
Do not remove or install a card while the system is executing the configuration replace file
•
command.
Make sure the replacement configuration file is created by using the configuration archive function
•
or the save command on the current device.
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.
