If it has been working, what changed?

No.  To get that level of help you need to open a PMR.

You can trace the *VSWITCH* by putting a Linux guest on the VSWITCH with 
sniffer (promiscuous mode) authority and gather a TCPDUMP.  You'll see all 
the traffic on *that* VSWITCH.  Tracing the traffic leaving the OSA itself 
is done exactly as your network guys are doing - with sniffers.

Beware that OSA port sharing enables the OSA to "short cut" the packets if 
it recognizes the destination MAC or IP address as belonging to the OSA. 

And you know how I am about providing pictures, IP addys, and subnet 
masks.  I can't tell if the various hosts are [supposed to be] in the same 
subnet or not.  I get sleepy when I read ankle-bone-leg-bone-hip-bone 
configuration descriptions, particularly where shared OSAs come into play.
