Symptoms

Assume that you use the SnmpMgrTrapListen function to receive Simple Network Management Protocol (SNMP) traps on a computer that is running Windows 7 or Windows Server 2008 R2. However, the function does not receive SNMP version 2 (SNMPv2) traps.

Cause

The SnmpMgrTrapListen function uses the SnmpRecvMsg and SnmpGetPduData functions to receive the traps. The SnmpRecvMsg function returns the traps in the Community-based SNMPv2 (SNMPv2C) format, and then the SnmpMgrTrapListen function converts the traps to a version 1 format. This issue occurs because of a problem during the conversion of the traps from the version 2 format to the version 1 format.
