Chapter 5 Managing the ACE Software Using the Configuration Checkpoint and Rollback Service Using the Configuration Checkpoint and Rollback Service This section describes how to make a checkpoint (or snapshot) of a running configuration on your ACE and how to use the rollback service to revert to the last known stable configuration. It contains the following topics: • Overview • Creating a Configuration Checkpoint • Deleting a Configuration Checkpoint • Rolling Back a Running Configuration Overview At some point, you may want to modify your running configuration. If you run into a problem with the modified configuration, you may need to reboot your ACE. To prevent having to reboot your ACE after unsuccessfully modifying a running configuration, you can create a checkpoint (a snapshot in time) of a known stable running configuration before you begin to modify it. If you encounter a problem with the modifications to the running configuration, you can roll back the configuration to the previous stable configuration checkpoint. The ACE allows you to make a checkpoint configuration at the context level. The ACE stores the checkpoint for each context in a hidden directory in Flash memory. If, after you enter additional commands to modify the current running configuration, you enter the rollback command option, the ACE causes the running configuration to revert to the checkpointed configuration.
