Appendix A.1.2. Receiving SNMP TRAPs using the SNMP Client
In order to receive Traps, the SNMP Client requires a Map Descriptor to be configured for each OID that is to be updated via a Trap. Note
that a single Trap message may contain multiple OID’s, depending on the Agent originating the Trap. Each OID of interest requires its
own Map Descriptor. The Map Descriptor Function must be set to Passive_Client.
Example:
// Server Side Map Descriptors
Map Descriptors
Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, Node_Name, SNMP_OID
A1, DA_AI3, 0, Passive_Client, Agent 1, 1.3.6.1.4.1.6347.1.1.0,
A2, DA_AI3, 1, Passive_Client, Agent 1, 1.3.6.1.4.1.6347.1.1.1,
The OID specifies the value that will be stored by this Map
Descriptor following a TRAP update.
Traps can only be received by Map Descriptors with
the Function set to Passive_Client.
