Jim,
You can use equipment like an Ixia box to drive traffic it has the
advantage over simple ping etc in that you can shape the traffic, add delays,
jitter etc, and monitor the data throughout the test, particularly immunity
testing. It's a bit pricey but it has numerous capabilities and I would be
somewhat surprised if you're designers aren't using something similar to look
for latency and all the other network parameters they have to test
functionally. They've been around for awhile so If Uncle Terradata is squeezing
the check book you could likely find used units around - but you would have to
make certain they have the bit rates you want. You can set up pairs of ports
on the same LAN with the command line editor very easily, and then drive the
traffic into the first LAN, and daisy chain the ports together driving the
traffic through all port and back into the Ixia receive side.
Ixia is only one of the Ethernet traffic generators it just happens to
be the one I've used in the past.

At minimum, usually the case in development, continuous pings. Later, xmit a
file, read the file compare, in a fashion that is quick, as in single digit
seconds. Emissions, look for 125 MHz and harmonics. Immunity, look for missed
or slow pings, or mis-copied files.
