Flow Monitor: Top Protocols
This dashboard report displays the transport layer protocols (TCP, UDP, ICMP, etc.) used the most, traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface. This data is useful in determining what protocol is used the most on a network during a specified time period.
: This report only displays layer 4 networking protocols. Other traffic that is commonly referred to as a protocol, such as HTTP, FTP, or IMAP, is displayed on the Top Applications dashboard 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 protocol name.
- 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.

- Click the interface name at the top of the dashboard report to view the Flow Monitor Interface Details report for the selected interface.
- Click an entry in the far left column of the dashboard report to view the Interface Details report for the selected interface. The entry that you click will be applied to the report as a keyword filter.
Configuring this dashboard report
- In the title bar of the dashboard report pane, select . The Configure Report dialog appears.
- Enter or select the appropriate information:
- . Enter a title for the dashboard report. This name appears in the title bar of the dashboard report's pane.
- . Select the timeframe for the traffic about which you want to see a report. You can select either the last 5, 15, or 30 minutes, or the last hour.
- . Select the router interface that is used by the traffic you want to see in this report.
- . Select a direction for which the report will display data for the selected interface (In, Out, or Both).
- . Enter the number of individual items within the category you want to display in the dashboard report. The report displays the top values based on the sort option selected in Bytes, Packets, or Flows. All other items in the category are included in the 'Others' category, and are displayed when is selected.
- . Select the display type you want to use in the dashboard report. Choose Chart and data, Data only, or Chart only.
- . Select the type of chart you would like the report to display. Choose Pie chart, Pie chart (3D), Pie chart (transparent 3D), Bar chart, Bar chart (horizontal), Bar chart (transparent 3D), or Stacked Time graph.
- . Specify how wide, in pixels, the graph or chart should appear.
- . Specify how tall, in pixels, the graph or chart should appear.
- . Click this button to apply a filter by which report data will sort. After clicking, filter fields appear below the button.
