An HP Provision switch loses its OpenFlow connection to the HP VAN SDN Controller. How is traffic processed by default if no controller teaming is configured?
Packets and messages destined to the controller are dropped. Flows continue to expire according to their time-outs. This is because the default setting on HP Provision switches is fail- secure.

A switch connects to the HP VAN SDN Controller, which has the HP Network Protector SDN Application installed. These are the switch details: Switch: 3800-24G-2XG Firmware: KA15.14.003 OpenFlow negotiated: 1.3 Which channel will be used for communication with the HP Network Protector application?
A network environment consists of multiple switches. Some of the switches are configured for OpenFlow 1.0, and some of the switches are configured for OpenFlow 1.3. These switches are configured to communicate with an HP VAN SDN Controller. What is the result of the negotiation?
All OpenFlow switches successfully negotiate to use OpenFlow 1.3 with the controller, and OpenFlow 1.0 switches ignore OpenFlow 1.3 extensions.
An administrator wants to secure the connection between an HP Provision switch and HP VAN SDN Controller What is the recommended approach to securing the OpenFlow messages?
Use an IPsec VPN between the HP Provision switch and the HP VAN SDN Controller to secure OpenFlow messages.
Which HP IMC SDN Manager functionality provides a detailed overview of OpenFlow counters and DPIDs?
SDN Manager OpenFlow device management
An HP VAN SDN Controller team is configured consisting of three controllers, using default settings. - The first controller is configured with IP address 10.1.1.1 and priority 10. - The second controller is configured with IP address 10.1.1.2 and priority 20. - The third controller is configured with IP address 10.1.1.3 and priority 30. Currently the third controller (IP address 10.1.1.3) is the leader device. An administrator reboots the third controller. Which controller will be the leader once this controller comes back online?
the controller with the IP address 10.1.1.2
A multicast application is used in a customer's environment that relies on IGMP. On an edge switch an Openflow 1.3 instance is configured in aggregation mode. By default, what happens to the IGMP traffic if no matching flow entry exists?
