OpenFlow Trace
This feature provides a trouble-shooting tool for observing (for a very brief period – 10 seconds
by default) the OpenFlow interactions captured in messages between the controller and the
network. Included are Open Flow messages received by the controller from the OpenFlow
devices it manages, and all messages sent from the controller to the devices (both the messages
received and the messages sent).
