To enable, disable snmp trap functionality. SNMPv1 traps are defined in RFC 1157, and SNMPv2c trap is defined as NOTIFICATION. SNMP traps enable this device to notify the management station of significant events by way of an unsolicited SNMP message. After the manager receives the event, the manager displays it and can choose to take an action based on the event. For instance, the manager can poll the agent directly, or poll other associated device agents to get a better understanding of the event.
