Just a few days ago I watched a facility's switched network go basically 'down' due to a jabbering NIC. A power cycle of the workstation in question fixed the issue. The network was a small one, using good midrange vendor 'C' switches. All VLANs on all switches got flooded; the congestion was so bad that only one out of every ten pings would get a reply, from any station to any other station, except on the switches more than one switch away from the jabbering workstation. Jabbering, of course, being a technical term..... :-) While managed switches with a dedicated management VLAN are good, when the traffic in question overwhelms the control plane things get unmanaged really quickly. COPP isn't available on these particular switches, unfortunately.
