An HP ProVision switch running K/KA15.17 is configured with an OpenFlow instance “sales.” The command version 1.3 has been configured on the instance. Which version of OpenFlow will be used by the switch instance?
- OpenFlow version 1.0 will be used as version 1.0 is the highest supported version. The command will be accepted by the switch, but not activated until a supported version of firmware is loaded on the switch.
- The switch will negotiate with a configured controller to always use OpenFlow 1.3. If the controller does not support OpenFlow 1.3, the switch will continue to use traditional pipeline processing.
