Rolling Back the Configuration over a Specified Number of Commits

When you roll back the configuration over a specific number of commits, you do not have to enter a specific commit ID. Instead, you specify a number x, and the software undoes all configuration changes made in the last x committed configuration sessions. The rollback process rolls back the configuration, commits the rolled-back configuration, and creates a new commitID for the previous configuration.

Tip To preview the commands that undo the configuration during a rollback, use the show configuration rollback changes command.

To roll back to the last x commits made, go to EXEC or administration EXEC mode and type the rollback configuration last x command; x is a number ranging from 1 to the number of saved commits in the commit database.

In the following example, a request is made to roll back the configuration changes made during the previous two commits:

RP/0/RSP0/CPU0:router# rollback configuration last 2

Loading	Rollback Changes.
Loaded Rollback Changes in		1 sec
Committing.
1 items	committed in 1 sec	(0)items/sec
Updating.
Updated	Commit database in	1 sec
Configuration successfully		rolled back 2 commits.

Loading CommitID Configuration Changes to the Target Configuration

If the changes saved for a specific commitID are close to what you want, but a rollback is not appropriate, you can load the configuration changes for a commitID into the target configuration, modify the target configuration, and then commit the new configuration. Unlike the rollback process, the loaded changes are not applied until you commit them.
