The SNMP_Trap Action allows you to create an SNMP Trap using three values, the OID, the data, and the Device. To start, it uses an OID as the first value of the action. This is to specify the SNMP Host. The second value is the message that will be sent to the SNMP Host. Lastly, the third value is the SNMP Device, which can be created in the Device tab. This values is actually optional, and the message created will be sent to the SNMP Host defined by the SNMP application from the OID if a device is not set.
