Displaying Configuration History

When you commit a configuration, the device saves the current operational version and the previous 49 versions of committed configurations. To manage these configuration files with the J-Web interface, select Maintain > Config Management > History. The History Database Information page displays Database Information and Configuration History (see Figure 19).

Note: After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.
