I have no idea what sort of sniffers exist(ed) for HP-UX.  But based on 
timing, it sounds like you need something off box.

I keep an old hub around just for things like this.  Machine in 
question, uplink, and the sniffer.  Then I start tcpdump or wireshark on 
the sniffer before booting the machine in question.

I've learned to trust the bits on the wire.  At least until I have 
something to suggest that they are corrupted.
