Paessler Netflow Tester dumps the data of all Netflow
packets that a computer receives from a Cisco router.
This can be useful when debugging bandwidth monitoring
configurations based on Cisco's Netflow protocol.
First the Netflow protocol must be enabled and
configured on the router. Then the router must be
given the IP address of the computer running Netflow
tester so that the UDP data packets with Netflow data
are sent to that computer.

Just follow these simple instructions:

1) Download Paessler Netflow Tester and then start
netflowtest.exe

2) Enter the IP and port number that you have
configured as netflow packet target in your Cisco
Router. Usually selecting "any IP" should work, in
some cases the IP must be explicitly selected.

3) Enable "Start Netflow Collector".

4) You should now see a line in the logfile for each
packet the computer receives. Each line shows the
time, netflow version, number of flows and the IP of a
packet (note: You need netflow version 5 for PRTG
Traffic Grapher!)

5) Enable "Show Flow Data" to also show the
corresponding flow data.

6) If you do not see any activity then the system does
not receive any netflow data (e.g. due to
misconfiguration of the router or a firewall blocking
the packets, etc.)
