One type of message an SNMP agent application can send to a WinSNMP manager application is an asynchronous message that informs the application of a significant event. An example of a significant event is when a network link shuts down or when an authentication failure occurs.
These types of messages are called traps under SNMPv1 and notifications under SNMPv2C. The Microsoft WinSNMP implementation always translates SNMPv1 traps to the SNMPv2C format, as defined by RFC 1908.
