Need to trigger off of Ethernet "Data" (i.e. "Payload")

We are doing ethernet data testing and thus have a need to trigger off of 10BaseT, 100BaseT, 1000BaseT ethernet "data". When I say "data", I mean the area of the ethernet packet or data stream, where the actual data (payload) resides... our only apparent capability is to trigger at the beginning of the ethernet (physical layer) signal.  We need to be able to go drill deep into the packet, and identify or select (i.e. "trigger off of") the data (payload) area (i.e. bypass all of the pre-amble, source / destination addressing, and all other "pre-data" areas of the data stream.

Not too familiar with protocol analyzers but even so, I'm thinking we need oscilloscope capabilities, since we are dealing with the Physical Layer... Thoughts? What are our options?

Thank you,
