Ok, see, now I (like, I suspect, Frank Bulk) am confused again:
when you say "which L2 channels the RTP packets were flowed onto", that
sounds to me a *whole* lot like "which VLAN on the end-user drop carried
the RTP packets from the terminal adapter in their cable box to our
concentrator"... which is pretty much the point I was originally trying
to make, if perhaps in slightly different terms.
Am I still misunderstanding you?
