Top Sender Domains
This workspace report displays the top domains whose devices are generating traffic that is routed over the selected interface in the selected direction (Inbound, Outbound, Inbound and Outbound, or Bounce). The traffic displayed for each domain is the sum of the traffic generated by each device on that domain.
: The domains listed in this workspace report are obtained from the last two parts of a host name.
Domain data is useful in determining where the persons on a network are spending the most time. If you see a domain that isn't network-friendly, you can drill down by adding a filter for the domain and detect the device or devices visiting the suspect Web location.
- . Displays the top sender domain.
- . Displays the number of packets sent from the domain during the date range.
- . Displays the number of flows generated by the domain during the date range.
- . 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.

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.
