SNMP TRAP Resource
An SNMP TRAP is a message which is initiated by a network element and sent to the network management system.
For example, a router could send a message if one of it's redundant power supplies fails or a printer could send an SNMP trap when it is out of paper.
In SNMPv1, asynchronous event reports are called traps while they are called notifications in later versions of SNMP.
In SMIv1 MIB modules, traps are defined using the TRAP-TYPE macro;
in SMIv2 MIB modules, traps are defined using the NOTIFICATION-TYPE macro.
