SNMP's powerful write capabilities, which would allow the configuration of network devices, are not being fully utilized by many vendors, partly because of a lack of security in SNMP versions before SNMPv3, and partly because many devices simply are not capable of being configured via individual MIB object changes.
MRTG uses the Simple Network Management Protocol (SNMP) to send requests with two object identifiers (OIDs) to a device. The device, which must be SNMP-enabled, will have a management information base (MIB) to look up the OIDs specified. After collecting the information it will send back the raw data encapsulated in an SNMP protocol.
A Remote Terminal Unit for the DNP3 protocol can be a small, simple embedded device, or it can be a large, complex rack filled with equipment. The DNP User Group has established four levels of subsets of the protocol for RTU compliance. The DNP Users Group has published test procedures for Levels 1 and 2, the simplest implementations.
Net-SNMP is housed on SourceForge and is usually in the top 100 projects in the SourceForge ranking system. It was the March 2005 SourceForge Project of the Month. [1] It is very widely distributed and comes included with many operating systems including most distributions of Linux, FreeBSD, OpenBSD, Solaris, and OS X.
The DNS (Domain Name System), an SNMP (Simple Network Management Protocol) agent, in v1, v2 or v3, with private MIB (management information base) support and MIB compiler. Operating systems that implement the lwIP TCP/IP stack may provide a range of supporting clients and servers at the application layer.

It is built as a front-end for Net-SNMP. iReasoning MIB Browser: A graphical MIB browser, written in Java. Load MIB files and ...
A minimal MQTT control message can be as little as two bytes of data. A control message can carry nearly 256 megabytes of data if needed. There are fourteen defined message types used to connect and disconnect a client from a broker, to publish data, to acknowledge receipt of data, and to supervise the connection between client and server.
