Depends on what you consider legitimate, both quality and quantity
wise. MS Windows NLB (Network Load Balancing) floods stuff, so I have
~250Mbps minimum of flooded traffic on that VLAN... We disabled storm
control on the ports in that specific VLAN, and yes, we really will do
normal loadbalancing if I can get the Exchange admins to budge...

Enabled, it can prevent other bad stuff, like looped traffic, not per
se a loop on the specific switch. Plus, it's a switch, not a hub. :)
