What is NetFlow?
A network flow is a sequence of packets between a given source and destination in one
direction only. Cisco routers store and export information 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 distinguish flows from one another,
the source and destination addresses and application (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 packet belongs.
What is NetFlow Tracker?
NetFlow Tracker provides a powerful but easy-to-use set of dynamic charts and reports
to help the network administrator make sense of the NetFlow information provided by
his routers. The focus is on troubleshooting and diagnostics; long-term analysis is not
catered for.
