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.
