Has anyone used Ethereal to capture EhterNet/IP messages ?

Specifically I need to capture Class 3 CIP messages that are passed between a Logix5000 CPU and an EtherNet/IP compatable device. I whould like to have the PC attached to a hub running Ethereal and capture   these messages. 

Currently all I am able to see are Class 1 Output data messages that are transmitted by the field device.

How is it possible to see TCP messages between 2 devices if neither device is the computer which is running Ethereal?
