In the Simple Network Management Protocol (SNMP), a TRAP message is sent by an SNMP agent to an SNMP manager. The trap is an alert triggered by specific event changes on the agent's host device. Unlike other messages sent by SNMP agents it is not sent in response to an SNMP manager's request, but is sent autonomously. In later versions of SNMP, traps are known as notifications.
