Configuring Configuration Replace and Rollback
Configuring Configuration Replace and Rollback is a three-step process:
1. Enable the Archive Service.
2. Archive a Configuration File.
3. Replace the Current Running Configuration.
Related Configuration Tasks
• Configure an Archive File Maximum
• Configure Auto-archive
• Copy and Delete an Archive File
• View and Edit the Contents of an Archive File
Important Points to Remember
• FTOS automatically locks CONFIGURATON mode during the replace and rollback operation; see
Lock CONFIGURATION mode. Therefore, when using this feature, no other user may be in
CONFIGURATION mode. The lock is released when the replace or rollback operation is complete.
• Configuration Replace and Rollback cannot remove some FTOS configuration statements. See the
release notes for your FTOS version for details.
Enable the Archive Service
Before you can archive a configuration, you must enter ARCHIVE mode using the command archive from
CONFIGURATION mode, as shown in Figure 12-1. This enables the archiving service. If you do not
enable the archive service, Message 1 appears when you attempt to archive a configuration.
Figure 12-1. Enter Archive Mode
