CONTROL VIA REMOTE INTERFACE: SNMP
5.5.1
SNMP Overview
The "Simple Network Management Protocol" (SNMP) essentially is a
request-reply protocol running over UDP (usually ports 161 and 162). SNMP
is an asymmetric protocol, operating between two types of management
units: managers and agents.
A manager is called "Network Management Station" (NMS). This is usually a
computer, on which one or more management systems are running.
On small NMS, command line tools can be used. On larger NMS, normally
third-party software, also called a "network management suite" collects the
data and provides a graphical user interface.
An agent or SNMP-agent is software, which runs on a "Network Element"
(NE). NEs in a SNMP environment are called "nodes". An agent collects and
stores information from the system, translates the information in SNMP-
compatible form, and makes this information available to the manager. The
agents manage the "objects" of the node. Each of the objects has its own
individual management "Object ID" (OID). In the system, the objects are the
variables, which can be simple values or tables.
The information about the objects is stored in the "Management Information
Base" (MIB).
Note:
The iReasoning MIB Browser Personal Edition v6.11 (including Trap
Receiver) by iReasoning Inc. is recommended to test the communication
with the device via SNMP.

DEV Private Enterprise Number, Device Index Number
The Private Enterprise Number of DEV Systemtechnik GmbH is 21035.
The actual MIB content for the DEV 5071 starts with the object section
.dev5071, which has the Device Index Number 34. This concatenates to the
(MIB-) string (i.e. the numerical OID: .1.3.6.1.4.1.21035.34):
