SNMP is a protocol that enables server remote-info-exchange. Which according to wikipedia: it [collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior].
It is short for simple network management protocol. Typically, routers, switches, servers, workstations, printers supports it.
If need to test snmp locally, I suggest install net-snmp from source from tarball fetched from here (choose newest version).
Download and ./configure --prefix=/usr & make & make install should work.
Here is a file that most demonstrates the most widely used mib file.
And here is a tutorial that helps you walk through mib file content creation step by step.

It‘s only purposes is to hold the value of a single integer. Writing to it will simply change the value for subsequent GET/GETNEXT/GETBULK retrievals. This example object is implemented in the agent/mibgroup/examples/scalar_int.c file." DEFVAL { 42 } ::= { netSnmpExampleScalars 1 } netSnmpExampleSleeper OBJECT-TYPE SYNTAX Integer32 MAX-ACCESS read-write STATUS current DESCRIPTION "This is a simple object which is a basic integer. It‘s value indicates the number of seconds that the agent will take in responding to requests of this object. This is implemented in a way which will allow the agent to keep responding to other requests while access to this object is blocked. It is writable, and changing it‘s value will change the amount of time the agent will effectively wait for before returning a response when this object is manipulated. Note that SET requests through this object will take longer, since the delay is applied to each internal transaction phase, which could result in delays of up to 4 times the value of this object. This example object is implemented in the agent/mibgroup/examples/delayed_instance.c file."
