Procurve 2600 switches and Snmp

[BJørn Sigmund Stokke]

We have a great number of HP procurve 26xx switches in our network. We monitor this switches and a lot of other network components with SNMPc from castlerock. The switches is configured to send messages (event traps) to the snmpc-server by the command ( snmp-server host x.x.x.x public Critical )
The swiches generates somtimes messages like duplex mismatch, bad cable and so on. The problem is that we cant read out the port number where the error occures directly from the message sendt to snmpc. Anybody know any solution to this ?
