What is NetFlow?

Anetwork flow is a sequence of packets between a given s ource and destination in one
direction only. Cisco routers store and export informa tion about the network flows they
handle for network management purposes; high-end routers and switches use network
flows to accelerate security processing. In order to di stinguish flows from one another,
the source and destination addresses and applicati on (TCP/UDP) port numbers are
used. The IP Type of Service byte, protocol type and the ifIndex of the input interface
are also used to uniquely identify the flow to which a pac ket belongs.

What is NetFlow Tracker?

NetFlow Tracker provides a powerful but easy-to-use se t of dynamic charts and reports
to help the network administrator make sense of the N etFlow information provided by
his routers. The focus is on troubleshooting and diagnosti cs; long-term analysis is not
catered for.
