The SDN controller UI includes several screens providing information on OpenFlow enabled switches:
When the controller is active in an OpenFlow domain, the OpenFlow Monitor enables tracking of switch traffic summaries, packet traffic per port, and applied flow rules for switches detected in the controller domain.
For a graphical view of Data Path ID assignments to individual OpenFlow switches, see OpenFlow topology .
The main display lists the Data Path IDs and descriptive information for the active switches and the options for viewing traffic information. To view information about a specific device, click the Data Path ID for that device and then select one of these tabs for the view you want to display: Summary, Ports, Flows, Groups.
Click Refresh to update the display for Topology changes, such as a newly discovered OpenFlow device or the loss of a device that has been disconnected.
