Managing Configuration History and Rollback

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.

To load rollback configuration changes from the current configuration to a specific session, go to global configuration or administration configuration mode and enter the load rollback changes to commitId command:

RP/0/0/CPU0:router(config)# load rollback changes to 1000000068

To load rollback configuration changes from the current configuration to a specified number of previous sessions, go to global configuration or administration configuration mode and enter the load rollback changes last commit-rangecommand:

RP/0/0/CPU0:router(config)# load rollback changes last 6

In the preceding example, the command loads the rollback configuration changes for the last six commitIDs.

To load the rollback configuration for a specific commitID, go to global configuration or administration configuration mode and enter the load rollback changes commitId command:

RP/0/0/CPU0:router(config)# load rollback changes 1000000060

Deleting CommitIDs

You can delete the oldest configuration commitIDs by entering the clear configuration commit command in EXEC or administration EXEC mode. The clear configuration commit command must be followed by either the amount of disk space you want to reclaim or number of commitIDs you want to delete. To reclaim disk space from the oldest commitIDs, enter the clear configuration commit command followed by the keyword diskspace and number of kilobytes to reclaim:

RP/0/0/CPU0:router# clear configuration commit diskspace 50

Deleting 4 rollback points '1000000001' to '1000000004'

64 KB of disk space will be freed. Continue with deletion?[confirm]

To delete a specific number of the oldest commitIDs, enter the clear configuration commit command followed by the keyword oldest and number of commitIDs to delete:
