Displaying Configuration History
When you commit a configuration, the routing platform 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 main pane displays Database Information and Configuration History (see Figure 1).
Table 1 summarizes the contents of the display.
The configuration history display allows you to perform the following operations:
- View a configuration.
- Compare two configurations.
- Download a configuration file to your local system.
- Roll back the configuration to any of the previous versions stored on the routing platform.
