@@ -747,6 +747,27 @@ A: ovs-dpctl queries a kernel datapath, not an OpenFlow switch.  It
    won't display the information that you want.  You want to use
    "ovs-ofctl dump-flows" instead.
 
+Q: It looks like each of the interfaces in my bonded port shows up
+   as an individual OpenFlow port.  Is that right?
+
+A: Yes, Open vSwitch makes individual bond interfaces visible as
+   OpenFlow ports, rather than the bond as a whole.  The interfaces
+   are treated together as a bond for only a few purposes:
+
+       - Sending a packet to the OFPP_NORMAL port.  (When an OpenFlow
+         controller is not configured, this happens implicitly to
+         every packet.)
+
+       - The "autopath" Nicira extension action.  However, "autopath"
+         is deprecated and scheduled for removal in February 2013.
+
+       - Mirrors configured for output to a bonded port.
+
+   It would make a lot of sense for Open vSwitch to present a bond as
+   a single OpenFlow port.  If you want to contribute an
+   implementation of such a feature, please bring it up on the Open
+   vSwitch development mailing list at dev@openvswitch.org.
