How does it work?
• The sFlow exporting router monitors traffic traversing it
• ...and the router becomes an Exporter of sFlow data.
• It forwards information to the sFlow Collector
• Collector stores, correlates and presents the information about
• Traffic bottlenecks in networks.
• Applications responsible for bandwidth utilization.

Definitions
sFlow—For Delldevices.
Collector—Application listening on a UDP port for sFlow datagram.
Exporter—Network element that sends the sFlow datagram.
Conversations— IP communications between two network nodes.
Flow—A flow is a unidirectional stream of packets between two network nodes.

NOTE:
Counter sFlows do not appear as Traffic Flows, but essentially duplicate Performance metrics for
interfaces. Flows how data traverses between two endpoints. You can monitor interfaces with
Performance monitors. See Chapter 10, Monitoring.
