2.10 OpenFlow Trace
This troubleshooting tool logs OpenFlow conversations captured in messages to and from the
controller and the OpenFlow devices it manages. You can export the captured messages in the
trace log to a CSV (Comma-Separated Values) file that can be opened by applications such as
Excel that are designed to accommodate this file type. This enables you to create a filter to display
only the messages from the specific data paths you want to examine.
