The term rollback is used to refer to when a switch configuration is reverted to a pre-existing checkpoint.

For example, the following command applies the configuration from checkpoint ckpt1. All previous configurations are lost after the execution of this command: checkpoint rollback ckpt1

You can also specify the rollback of the running configuration or of the startup configuration with a specified checkpoint, as shown with the following command: copy checkpoint <checkpoint-name> {running-config | startup-config}
