The SNMP-Set Action allows you to perform an SNMP Set using four values, the OID, the data, the value type, 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 value that will be set for the OID value. The third value is the type of value you are trying to set for the OID. Lastly, the fourth value is the SNMP Device, which can be created in the Device tab. This value 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.
