The Top Ports dashboard report displays the top TCP or UDP ports used the most. Port usage data can be used to determine if new or unapproved applications are in use, and can be used to assist in port to application mapping that generates the Top Applications report. You can choose to display and sort sender traffic by bytes, packets, or flows using the report settings dialog.
