Viewing RCS Versions
You can view the RCS versions for a configuration page from the Config Tree or on the page itself. To compare versions, you can generate RCS reports. These RCS reports can also be filtered for specific time periods and administrator IP addresses.

- To view the RCS versions of a configuration page from the Config Tree, right-click the configuration node and select Show RCS Versions.
The RCS Versions window displays a list of all versions of a configuration page. It displays the following information:
|Version||The version numbers of activated (by clicking Activate) changes.If a configuration has only been sent (by clicking Send Changes), this column displays, "session."
If a linked file is edited, the file version and complete path to the link target are also displayed.
|Date||The date when the configuration version was activated. Dates are formatted follows: yyyy/mm/dd|
|Time||The time when the configuration version was activated. Unless you have changed the time settings for the system, the UTC time format is used.|

Generate an RCS Report
In the RCS Versions window, you can generate an RCS report to compare and view information for specific configuration versions. For configuration objects that contain at least one sub-node you can also filter RCS reports for specific time periods and administrator IP addresses. To generate a report,
- Open the RCS versions page.
- Select the versions that you want to include in the report. To select a range of versions, click the first version and last version in the range of interest. Then select the Full History check box. To select all versions, click Select All .
- Click Show Differences.
To generate a filtered report,
- Click RCS on the configuration page and select Show RCS Report.
- You can specify the following settings for the report:
- Start Date / End Date – The period of time that is to be displayed.
- Admin – (Optional) The login name of a specific administrator.
- Peer – (Optional) The IP address of an administrator
- Include Node Creation – Collects all available version information. This option may generate a high load of information.
- No Difference Details – Only specify if a change was made. The changed value is not displayed.
- Show Detail for Linked Nodes – Collects all available change information. Also displays changes made to a linked target. This option may generate a high load of information.
The RCS Report window displays the following information:
|Node||Displays changes in a tree structure. The first level specifies the name of the configuration entity, the second level specifies the name of the data set, the third level specifies the position in the configuration dialog, and the fourth level specifies the object of editing.|

|Admin||The name of the administrator who made changes for the configuration version.|
|Peer||The IP address of the administrator who made changes for the configuration version. If the same IP address is entered multiple times within a firewall rule, the RCS Report window may display incorrect change history even if the change was correctly deployed.|
