Your doubts come from the fact that you mixed too many things together.
What you have right now are,
-
SNMP Library and its samples, which show you how to perform basic SNMP operations (GET, SET, and so on)
- A lot of devices with SNMP enabled (their have SNMP agents running inside), which can accept your SNMP requests if you utilize #SNMP correctly
The missing piece is an algorithm that clearly translates "the port and switch that a device is connected to" to a set of SNMP operations (those operations might need to be performed on a single device, or a few devices in the network).
SNMP cannot help you find the algorithm, as it is such a general project. You
will have to,
- learn about existing MIB documents (such as IP-MIB), so as to see what are the necessary OID exposed.
- learn about computer networking, so as to see with the exposed information (such as interfaces, MAC addresses, IP addresses) how to draw a network topology out.
If possible, find someone with CCNA/CCNP certificates, and they should be able to share more insights with you.

Hi all,
This is an awesome lib and I would like to really get started. As a beginner in programming, I am just kind of lost to how to get started. I'm developing an application that will run from a console then based on IP, hostname, or MAC address (which I can get any of the 3 as long as I have one value) find the port and switch that a device is connected to. Is this possible? Would I use snmpwalk, snmpbulkget, or something totally different?
I seen the samples in the source code. I took a look at snmpwalk. Would I just make a class say SNMPWALK and then copy and paste that code in there or should I call the exe and will it give an output? The source is a bit hard to follow cause there are no comments describing what is going on. You're probably slapping your head right now.
We do have an SNMP v3 enabled. Do I need a server to connect to? Or does the request just travel through the network devices and find the destination while reporting each hop? The reason I'm asking is I just cannot seem to connect to any other device on the network. What am I missing? Please help.
Thank you.
