Incoming Interface Traffic
This NetFlow workspace report classifies and displays the traffic entering the selected interface by the traffic's destination interface.
In this report, an output interface is the destination of the selected interface's incoming traffic.
In some cases a router can send traffic it has just received back to the interface from which it came, much like a reflection on a mirror. This happens when the router has been misconfigured to view the destination device as itself. In NetFlow, this is called Bounce traffic. NetFlow Monitor alerts you to this abnormal traffic pattern by displaying a flag next to the interface(s) on which the error is occurring.
Below the chart, incoming traffic is summarized in bytes, by packets and flows, and as a percentage of the top x results from the current interface for the selected time period.
: You can hover over information in the column to display popup information with average data speed as a percentage of the total interface capacity.
: Interfaces with an index of 0 (zero) represent the null interface on the device. This interface is the originating interface for traffic generated by the device (such as NetFlow data) and the destination interface for traffic sent directly to the device.
