We have a network of apx 250 devices using HP Procurve switches all around, both for edge and core. Occasionally we have a problem where one device causes network problems which affect everyone. For example, last week an improperly configured printer, connected to a small 4-port switch which was then connected to one of our HP's turned out to be the culprit for an entire LAN slowdown. It took us a few hours of walking around to find it.
We have the ability to monitor the switches using SNMP and I'm wondering if there are any specific events or traps that the HP can send to say that traffic looks "suspicious" from a port? Perhaps a bad Cat-5 cable, a bad device, or whatever... just something so we can look at the monitor, see the suspect ports, and disable them.
