Configuring Configuration Replace and Rollback
Configuring Configuration Replace and Rollback is a three-step process:
1. Enable the archive service. See page 302.
2. Archive a running-configuration. See page 303.
3. Replace the running-configuration with an archived configuration. See page 303.
Related Configuration Tasks
• Configuring an Archive File Maximum on page 305
• Configuring Auto-archive on page 306
• Copying and Deleting an Archive File on page 307
• Viewing and Editing the Contents of an Archive File on page 307
Important Points to Remember
• FTOS automatically locks CONFIGURATON mode during the replace and rollback operation; see
Lock CONFIGURATION mode on page 72. 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.
Enabling 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.
