+---------------
+
+For an operational policy targeted towards VNF, the CDS actor always requires "vserver" information to query A&AI while processing ONSET events.
+Example of an ONSET event below:
+
+.. code-block:: bash
+
+    {
+      "closedLoopControlName": "ControlLoop-vFirewall-d0a1dfc6-94f5-4fd4-a5b5-4630b438850a",
