You said it was ``smart'' but you didn't mention the brand. What is the
model of the 8-port switch? It's more likely that you need a better
switch. What are the specs on it? How many PPS can it handle?
If the documentation doesn't tell you the performance that the switch
can deliver, then it's likely you need a better one.
If you are flooding the switch, even from a single server to many
clients, and it is actually the switch that is sending out the pause
frames, then that could potentially block all clients.
