A single HP VAN SDN Controller is used to control OpenFlow enabled switches that operate in virtualization mode. An internal application is installed on the controller that redirects classified traffic to a specific VLAN. The connection between the controller and the network is lost. The HP OpenFlow enabled switches' connection interruption mode is set to standalone mode.
What is the forwarding behavior of the OpenFlow enabled switches?
Correct Answer: B
Explanation/Reference:
OpenFlow instance connection interruption mode
You can set the type of behavior when the switch loses connection with the controller.
fail-standalone
If the switch loses connection with all of the controllers, packets and messages of new flows behave as a legacy switch or router would. Existing flows of this OpenFlow instance are removed.
