Goal

SNMPv2/v3 differentiate between error in retrieving information from the MIB (Management Information Base) tree and exceptional conditions that occur in handling an incoming request. The exceptions are more commonly known as SNMP Reports and on the wire are transmitted using special SNMP PDU (Protocol Data Unit) known as Report PDU.

Knowing how to interpret the report OIDs can help troubleshoot/ analyze communication issues with an SNMP agent. In case of SunMC the Report PDUs are logged in /var/opt/SUNWsymon/log/agent.log file and therefore can be looked at a later point in time as well.
