Some managed Ethernet switches have the ability to log into them and get information
on packets transmited/received on each port and errors that are detected. However,
these are typically proprietary. I am not sure about the Mellanox card. 

So I guess the answer is that you manage RoCCE and iWarp clusters just like
you would any Ethernet cluster, with existing management tools that are available
for managing Ethernet.
