Managing Configuration History and Rollback

After each commit operation, a record of the committed configuration changes is saved. This record contains only the changes made during the configuration session; it does not contain the complete configuration. Each record is assigned a unique ID, known as a commitID.

When multiple commitIDs are present, you can use a commitID to identify a previous configuration to which you want to return, or you can use the commitID to load the configuration changes made during that configuration session. You can also load configuration changes from multiple commitIDs, and you can clear commitIDs. If you are thinking about rolling back the configuration to a specific commitID, consider the following guidelines:

•You cannot roll back to a configuration that was removed because of package incompatibility. Configuration rollbacks can succeed only when the configuration passes all compatibility checks with the currently active Cisco IOS XR software.

•If an incompatible configuration is found during the rollback operation, the operation fails and an error is displayed.
