Transactional configuration relies on the rollback mechanism to operate. By default, the 7705 SAR automatically creates a new rollback checkpoint after a successful candidate commit operation. The rollback checkpoint includes the new configuration changes made by the commit. An optional no-checkpoint keyword can be used to prevent the creation of an automatic rollback checkpoint after a successful commit. If the commit fails, no rollback checkpoint is created. If the confirmed option is used during the candidate commit, a rollback checkpoint is created and exists whether or not the confirm command is issued.
Any configurations that are not supported in a rollback revert are also not supported in candidate edit mode. See CLI Configuration Rollback for more information.
