The checkpoint can then be reapplied to the switch via rollback to facilitate the restoration of the original configuration captured in the checkpoint. Checkpoint enables the network administrator to implement changes in the devices, configuration and back those changes out if required in a fast and reliable manner. When checkpoints are created by a network administrator, they are stored on the switch rather than an external server or device. Checkpoints can also be reviewed prior to application on the switch, and their execution is configurable in three modes: • Atomic: Implements a rollback only if no errors occur • Best-Effort: Implements a rollback and skips any errors • Stop-at-First-Failure: Implements a rollback that stops if an error occurs Note Atomic is the default rollback mode. NX-OS can generate checkpoints automatically when specific events happen. The intent for the automatic checkpoints is to minimize network downtime because of disabling key features or when a license expires. Specific triggers for these automated checkpoints include • Disabling a feature with the no feature command • Removing an instance of a Layer 3 protocol, such as Enhanced Interior Gateway Routing Protocol (EIGRP or PIM) • License expiration of a feature The system-generated checkpoint names begin with system- and includes the feature name. Example 7-35 shows the system-generated checkpoints.

Note System checkpoints do not reduce the number of user-defined checkpoints. Checkpoints can be given a name and description and can be redirected to a file. Example 7-36 shows the creation of a checkpoint named one. Example 7-36.

The clear checkpoint database also removes all checkpoints. NX-OS provides context-sensitive help for checkpoint filenames and displays them when you use the ? on the show checkpoint command. Example 7-37 demonstrates this behavior and shows all user- and system-created checkpoints.
