PDU

PDUs contain SNMP requests or responses. A client application will send a PDU to the SNMP server, and then the server replies with another PDU.

In a typical GET scenario, a request PDU will contain one or more SNMP OIDs with a NULL value. The SNMP server then sends back a PDU with the appropriate values for each OID.

SNMPpp::PDU

The C++ PDU class is a wrapper for the netsnmp_pdu structure. With the class, you can easily add OIDs, or read back the value the server provided in the response.

Note that PDUs don't automatically send themselves to the server. A PDU is bascially a list of OIDs. Once you create a request PDU, you must combine a session handle and the PDU in a call such as SNMPpp::get(...) to have the SNMP server reply.

For example:

SNMPpp::PDU pdu( SNMPpp::PDU::kGet );
pdu.addNullVar( "1.3.6.1.2.1.1.1.0" );
pdu.addNullVar( "1.3.6.1.2.1.1.2.0" );

// this will free up the request PDU and return a new result PDU
pdu = SNMPpp::get( handle, pdu );
