Comparing Configuration Files

To compare any two of the past 50 committed configuration files:

  1. Select Config Management > History.

    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.

    Note: 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: http://support.microsoft.com/kb/323308. 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.

    A list of the current and previous 49 configurations is displayed as Configuration History in the main pane (see Figure 19). Table 66 summarizes the Configuration History display.

  2. Select the check boxes to the left of the two configuration versions you want to compare.
  3. Click Compare.

    The main pane displays the differences between the two configuration files at each hierarchy level as follows (see Figure 20):

    • Lines that have changed are highlighted side by side in green.
    • Lines that exist only in the more recent configuration file are displayed in red on the left.
    • Lines that exist only in the older configuration file are displayed in blue on the right.
