Which Open Flow plane is responsible for forwarding the packets?
A. Control plane
B. Application plane
C. Management plane
D. Data plane
Correct Answer: D
Explanation/Reference:
Explanation: The forwarding table is delivered to the data plane by the management plane as part of the device operating system. Thus when an Ethernet frame arrives on the switch interface, the data plane then forwards it to output port.
Note: OpenFlow defines a standard for sending flow rules to network devices so that the Control Plane can add them to the forwarding table for the Data
Plane.
Incorrect:
Not A: The control plane will use the routing table to build the forwarding table used by data plane. Not C: The Management Plane handles functions such device management, firmware updates, SNMP and external configuration via the CLI.
Reference: OpenFlow and Software Defined Networking: Is it Routing or Switching ?
