Agreed.  Might see if I can get netstat -antp output from the operators at =
some point though.

I will start with one of the hosts, looks like the whole flow capturing exe=
rcise for this LAN will need to be done using multiple laptops connected to=
 the different access ports for the hosts.  No RSPAN support on these switc=
hes and no netflow :(

It's better to collect as much information you have without perturbing
