You’ll need to learn the SNMP protocol by reading the RFCs and write an SNMP client.

You might be able to use Wireshark to get a packet capture of another program sending the GET, and then write your own code to send a similar byte stream. But you’ll need to figure out how to decode the response.

Look at the existing SNMP server code, since you might be able to use pieces of it for encoding and decoding packets.

But confirm which version of SNMP your target device uses. I think the SNMP library in Dynamic C was using SNMPv1 which is an older version of the protocol.

You will need to create a MIB file and import that file into a MIB Browser. iReasoning (www.ireasoning.com)  has a free browser you can download.
The SNMP version used by Rabbit is v1.

Digi’s SNMP library was bundled into both Dynamic C 9.62 and Dynamic C 10.72, but I’m pretty sure it only supports SNMP server mode (responding to requests).
