Maintaining Configuration Management History

  1. Select Maintain>Config Management>History in the J-Web user interface.

    The History page appears. Table 258 explains the contents of this page.

    When you use an HTTPS connection in the Microsoft Internet Explorer browser to save a report from this page in the J-Web interface, the error message "Internet Explorer was not able to open the Internet site" is displayed. This problem occurs because the Cache-Control: no cache HTTP header is added on the server side and Internet Explorer does not allow you to download the encrypted file with the Cache-Control: no cache HTTP header set in the response from the server.

    As a workaround, refer to Microsoft Knowledge Base article 323308, which is available at this URL: Also, you can alternatively use HTTP in the Internet Explorer browser or use HTTPS in the Mozilla Firefox browser to save a file from this page.

  2. Click one:
    • Number — Displays a configuration .
    • Compare — Compares two configurations files that you select.
      • The main pane displays the differences between the two configuration files at each hierarchy level as follows:
        • Lines that have changed are highlighted side by side in green.
        • Lines that exist only in the most recent configuration file are displayed in red on the left.
        • Lines that exist only in the least recent configuration file are displayed in blue on the right.
    • Download — Downloads a configuration file to your local system.
      • Select the options on your Web browser to save the configuration file to a target directory on your local system.

        The file is saved as an ASCII file.

    • Rollback — Rolls back the configuration to any of the previous versions stored on the device.
      • The main pane displays the results of the rollback operation.

        Click Rollback to load the device and download the selected configuration. This behavior is different from entering the rollback configuration mode command from the CLI, where the configuration is loaded, but not committed.

Enter the information specified in Table 258 to maintain the secure router.
