I have an Avaya IP office which is configured to send errors by email. It is normally quiet, however it sometimes decides to send a stack of emails containing:
Invalid community specified in SNMP request
I can reproduce by pointing a SNMP client at the PBX with the wrong community string. One would think that there must be a monitoring daemon (e.g. nagios) configured somewhere with the wrong community string, but this is not the case. I have enabled as much debugging as I can on the PBX to try and find out what IP address it is coming from, but so far no luck.
Just wondering if anyone has seen this sort of behaviour on the Avaya IP office before? Or some way to determine what is connecting to it with the wrong SNMP community string?
I am tempted to set up port mirroring on the switch and capture SNMP traffic!
