The HP NMTRACE facility may very well be able to do this, but I never
learned the details, other than it is a horribly painful process (from
being walked through one once by the response center) resulting in you
reviewing crude dumps of the results.

A span port would do nicely, or stick a dumb hub between your 3000 and
it's usual network connection and you can sniff from any of the other
hub ports.  Be careful about speed and duplex, as the hub will make it
half-duplex if it isn't already.

Wireshark (formerly ethereal) is hard to beat for capture/analysis, it's
available for linux / mac / windows.  Fire it up on a computer attached
to the span port created above, and filter on "port 32075".  Or if you
just want TCP traffic, "tcp port 32075". 

If the "connectivity" you're trying to decipher involves a
windows/mac/linux thing on the other end, you can also run wireshark
natively on the "client" and capture real-time without the need for any
type of span/sniffer port.
