Managing Configuration History and Rollback
Note Unlike the rollback process, loading the commit ID configuration changes loads only the changes made
during that commit operation. The load process does not load all changes made between the commit ID
and the current committed configuration.
To load commit ID changes in the target configuration, go to global configuration or administration
configuration mode and enter the load commit changes command with the commit ID number. In the
following example, show commands are used to display the changes for a commit ID, the commit ID
configuration is loaded into the target configuration, and the target configuration is displayed:
RP/0/RSP1/CPU0:router# show configuration commit changes ?
last Changes made in the most recent <n> commits
since Changes made since (and including) a specific commit
1000000217 Commit ID
1000000218 Commit ID
1000000219 Commit ID
1000000220 Commit ID
1000000221 Commit ID

end
Loading Rollback Configuration Changes to the Target Configuration
If the changes for a specific rollback point are close to what you want, but a rollback is not appropriate,
you can load the rollback configuration changes 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.
Tip To display the rollback changes, enter the show configuration rollback changes command.
