Paessler NetFlow Tester is a small program that simply 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, e.g. in order to find out whether packets actually reach the target system.
