Rollback

The term回滚用于refer to when a switch configuration is reverted to a pre-existing checkpoint.

For example, the following command applies the configuration from checkpointckpt1. All previous configurations are lost after the execution of this command:检查点回滚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{running-config | startup-config}
