If you have some pointers, I would be happy to post the information.What I think would be very cool is if Wireshark would support sFlow directly as a virtual interface under the Capture menu. Wireshark can dissect NetFlow traffic as it travels from the NetFlow Agent (your router) to the Collector (absent in your network if I read your question correctly). The headerProtocol field is set to unknown, so the receiver can't know how to interpret the headerBytes, for example, an exported Ethernet frame should have headerProtocol=1 (ETHERNET-ISO88023) Hardware slap a shim header 8 bytes and followed by original sampled packet. They can be very useful when trying to solve application layer issues but they often won’t give you much information on the actual performance of your network. Suggestions.
