There is a nice demo script that was developed to show the use case for LiveAction (made by ActionPacked - a Cisco partner) specifically using the 2960-X. If can be downloaded from this link.
In case that doesn't work, here are the relevant bits of their switch configuration. (The addresses and source interface would change based on your setup and PI listens for Netflow on udp/9991 vs. udp/2055.)
