how to rollback configuration

[choi_seonghyeon]

I would like to restore the configuration in such a way that I can not enter the command incorrectly and reboot.

Is there a way to recover settings during operation?

For example, I want to know commands such as Juniper's rollback and cisco's replace rollback.

thanks.

hi David

Is there no way to do this without rebooting?

There is no backup config.
