# Virtual Fabrics Management

The figures below show the Virtual Fabrics Management user interface. It's very similar to Applications Management. When you load an old version of opafm.xml that doesn't support QOS groups, use the interface shown in the first figure to directly set QOS related parameters. When the loaded opafm.xml supports QOS Groups, use the interface shown in the second figure to specify the QOS Group for a Virtual Fabric.

Both interfaces have a similar configuration editor panel on the right side. Use this panel to specify basic administrator policies; for example, to enable one virtual fabric and specify whether it should provide security control and/or QOS control.

Please note that for QOS group, the QOS control box is grayed out because its value comes from QOS group. A user can not directly change it within the editor panel. The administrator policies attributes can be used only once and the used attribute is identified with an icon to indicate that it is not available.
