I would list all switches and their firmware versions. Update firmware one by one when a newer version is available.<br />
Problems like yours aren't fixed by monitoring. Updated firmwares isolate problematic ports.

thanks @strivoli but once upgraded and problematic ports are isolated, how can i get alerts to the issues?

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.<br />
<br />
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 &quot;suspicious&quot; 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.<br />

Thanks.

Monitor for LAN problems on HP Procurve

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
