NOTE: OpenFlow 1.0 is the default version of OpenFlow for HP ProVision switches. OpenFlow does not allow the controller to optimize flow location in hardware tables. For concerns about
Uncontrolled switches in an OpenFlow Hybrid network are not visible to or controlled by the HP VAN SDN Controller. Uncontrolled switches are either controlled by another controller (outside the team) or not controlled at all (traditional networking). Traffic by such switches is independently managed.
The VAN SDN Controller Path Diagnostic Tool is useful only when hybrid mode is disabled. When hybrid mode is enabled, the controller does not monitor or direct all flows in the network. As a result, the path diagnostic tool (PathDiagnosticManager) does not have visibility into all flows on the network, and should not be used.
6.4 Controller packet-forwarding when hybrid mode is disabled
Figure 46 Controller operation with hybrid mode disabled
When hybrid mode is disabled (set to "false"), the controller examines and directs the packets in all flows for the given OpenFlow instance. The controller forwarding decisions for flows in a given instance are based on the requirements of the installed applications. The forwarding decision is communicated to controlled switches through OpenFlow. In instances where the controller has not provided the switch with a rule for how to forward a packet type, the switch sends the packet to the controller and waits for the controller to provide forwarding instructions.
Hybrid mode is commonly disabled in networks that are either used for experimental OpenFlow work (such as developing a controller application) or for networks that are completely new and designed to be fully controlled by OpenFlow.
