Need to measure the UDP traffic between two nodes on a network using WireShark

Hi,

I'm fairly new to Wireshark, but understand how to set filters etc.

I need to measure the comms traffic between two applications on a network, that communicate via UDP.

The problem is, with UDP, the packets obviously don't have destination IP addresses, so what kind of filter can I write?

I have considered installing the application on the receiving node, but for reasons I won't explain, this is not an option. I intend to use wireshark on a laptop plugged into to a spare port on a switch.

Can anyone advise on how I might achieve this?

Thanks

Have you try to plug the sniffer on the interface that receive the UDP traffic ? And then, set the filter  to protocol "UDP" ? Do you know the application that communicate via UDP in your network or do you want to know, specifically, that ?

Sorry, my mistake, the UDP packets do have source and destination addresses.

And you are correct, it appears that I will have to install the sniffer on the node that recieves the comms.

Thanks for your input.
