Top Ports
The Top Ports report displays the top ports to which traffic is routed on the selected interface in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce). By default, Flow Monitor listens to ports below 1023, and a few higher numbered, well-known ports. You can configure monitored ports on the Flow Ports dialog.
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 option on the report configuration dialog. Providing alternate sorting methods allows you to monitor and identify hosts that are the largest consumers of interface resources other than bandwidth.
- . Displays the port associated with the application.
- You can select one of the following units to display and sort the specific items in the report using the option on the report configuration dialog. The selected option appears as the first column header in the report and is used to sort the top "n" items.
- . Displays the total number of bytes transmitted for the specific item in the report category for the selected date range.
- . Displays the total number of packets for the specific item in the report category for the selected date range.
- . Displays the total number of flows for the specific item in the report category for the selected date range.
- . Displays the average bit rate, packet rate or flow rate, in multiples of the selected unit (e.g. Kbps, Mbps, or Gbps) for the specific item in the report category for the selected date range.
- . Displays the percentage of the total available bandwidth used by the specific item in the report category for the selected date range.
: Utilization is displayed as N/A if a speed is not specified for the interface, or if you have selected to display packets or flows in the report. If you are displaying bytes, you can set the interface speed on the Flow Interface dialog. To navigate to the Flow Interface dialog, click the link in the message appearing above the dashboard reports.
- . Displays the percentage of the total traffic for the specific item in the report category for the selected date range.
- . Displays the total of all of the items in the report category, specified and unspecified (). This row shows the interface totals for each column in the report.

About interface traffic directions
: For illustration purposes, the descriptions and diagrams in the table below assume that traffic is passing from an internal interface to an external interface or vice versa. In reality, traffic may pass from an internal interface to another internal interface, an external interface to another external interface, or traffic may be routed out the same interface it enters.
