I doubt this can be done.
The mention of "another network" implies a router is involved, and hence
the router will hide link-layer information such as MAC addresses on the
remote network behind its own MAC address, and AFAIK, routers should not
forward ARP requests to other subnets (to do so would cause chaos).
[ I should point out that I'm assuming IPv4 here... ]
However, I'm not sure that achieving what you want would actually
further your investigation.
Even if you knew the remote MAC address, how would this help you?
An alternative may be to snoop simultaneously at both ends of the
connection being dropped, then compare the traffic seen (making sure you
check for any drops).

hi Folks,
I'm not sure if this is possible.
Long story short is that we've got an M4000 that is dropping its connections.
We think it is because of a teamed broadcom system on another network.
They are both production servers, so I can't just start installing stuff.
My plan is to use an Open Solaris machine to monitor the situation.
To that degree, I've got to get Open Solaris to query a machine outside its own
subnet ... for its MAC address.
Obviously arp and netstat -p are only listing within this subnet.
Any ideas as to how I achieve this please?
Many thanks for any ideas,
Michelle.
