About Flow Sources

Flow sources are network devices that use one of the following supported network monitoring protocols to send flow data to Flow Monitor.

Flow sources that use these network protocols provide detailed data about individual flows to Flow Monitor gathered from flow records. An example of the types of information that can be contained in a flow record are:

Configuring Flow sources is a three-part process:

  1. Configuring Flow devices to send Flow data to Flow Monitor. For more information, see Manually configuring devices to export flow data to Flow Monitor.
  2. Configure Flow Monitor to listen for flow data on the appropriate port. For more information, see Configuring Flow Monitor to listen for NetFlow data.
  3. Setting options for the Flow source in Flow Monitor.

SNMP Polling

While Flow Monitor normally receives flow data from a flow source, it can also poll a source using SNMP to gather data from a network device. Flow Monitor can actively poll a source for the following data:
