Top Applications
This workspace report displays the applications used by devices generating the most traffic traveling in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce) on the selected interface. Applications correspond to ports that are used by IP protocols (80:http, 110:pop3, 443:https, etc.). By default, NetFlow Monitor monitors ports below 1023, and a few higher numbered ports. You can configure monitored ports on the NetFlow Ports dialog.
Application data is useful in determining the types of tasks persons on the network are conducting the most over the selected time period. For example, pop3 indicates a person is checking email, while http signifies other Web-based tasks.
Port-specific application traffic is reported in bytes and as a percentage of the top x results from the current interface for the selected time period.

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.
