Outgoing Interface Traffic

The Outgoing Interface Traffic dashboard report displays the percentage of the total outbound traffic through an interface, that entered through each of the input interfaces.

Occasionally a misconfiguration can cause a device to recieve traffic it has just sent. Flow Monitor alerts you to this abnormal traffic pattern by displaying a flag next to the interface(s) where the error is occuring.

Below the chart, a table is provided that includes the number of bytes, packets and flows for each input interface, as well as the percentage of the total outbound traffic that is coming into that interface.

Note: sFlow, NetFlow-Lite, and J-Flow data is sent every x number of packets (configurable on the device), whereas regular NetFlow provides statistics about all of the network traffic. This means that sFlow, NetFlow-Lite, and J-Flow data provides a sampling of network traffic data that is not absolutely accurate, whereas NetFlow provides statistics about all network traffic data so that network traffic data is highly accurate. However, typically sFlow, along with the sample packets, sends accurate total interface traffic.
Data sampling methods may result in Interface Overview and Interface Detail reports that appear to have more or less traffic than is shown in the Flow Monitor Home page source information. This is because the sampled data shown in the Interface Overview and Interface Detail reports are derived the sampled data and the Flow Monitor Home page source information is derived from the total interface traffic data.

Tip: You can hover over information in the Bytes column to display popup information with average data speed as a percentage of the total interface capacity.

Note: 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.
