+      <p>
+       The NetFlow passive timeout, for flows that become inactive,
+       is not configurable.  It will vary depending on the Open
+       vSwitch version, the forms and contents of the OpenFlow flow
+       tables, CPU and memory usage, and network activity.  A typical
+       passive timeout is about a second.
