Today a very short and simple post to learn how to rollback configurations performed via tmsh.
After executing some commands, if finally we need to undo those changes we can get it, at least, by the following ways:
- In case of HA environment, the standby node configuration can be sync so that we set the active (changed) node to the same configuration state as the standby one.
- In case the “save config” has not been executed after the configuration commands, the changes are still only in memory and the saved (previous) configuration can be reloaded by using this command:
load sys config
