OpenFlow Agent Packet In and Out Feature

The Packet In and Out feature allows a flow to be programmed by the OpenFlow Agent logical switch so that
packets are sent to the Controller. The special output port: OFP_CONTROLLER is specified for the flow

The Packet In and Out feature enables support for the OpenFlow output-to-port action. The output action tells
the OpenFlow Agent to send all packets matching the flow to a specific port.

• Flow Exporter Map—Specifies the destination IP address of the NetFlow collector where the NetFlow
• Flow Monitor Map—Specifies the profile of the NetFlow producer, including the timeout values of
• Sampler Map—Specifies how often Network Processor (NPU) needs to sample incoming and outgoing
