Top Protocols
This workspace 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 workspace report.
- . Displays the protocol name.
- . Displays the bytes per second for the report category.
- . Displays the percentage of the total available bandwidth used by the report category.
: Usage is displayed as N/A if a speed is not specified for the interface. You can set this speed on the Flow Interface dialog. To navigate to the Flow Interface dialog, right-click on the interface on which you want to set the speed, then click .
- . Displays the percentage ranking of the item within the top "n" items of the report category.
: You can hover over information in the column to display popup information with average data speed as a percentage of the total interface capacity.

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.
