WAGO-I/O-SYSTEM 750
750-882 Media Redundancy ETHERNET Controller
In SNMP version 3, exchanging messages is user-related. Each device, that
knows the passwords set via WBM, may read or write values from the controller.
In SNMPv3, user data from SNMP messages can also be transmitted in encoded
form. This way, both requested values and values to be written cannot be easily
decoded by others via ETHERNET. This is why SNMPv3 is often used in safety-
related networks.
The device data, that can be accessed or modified by an SNMP agent, is called
SNMP object. The sets of SNMP objects are stored in a logical database called
Management Information Base (MIB); this is why these objects are typically
known as "MIB objects".
The SNMP of the ETHERNET controller includes both the general MIB acc. to
RFC1213 (MIB II) and a special WAGO MIB.
SNMP is processed via port 161. The port number for SNMP traps (agent
messages) is 161. Both ports must be enabled to use SNMP.

12.1.2.7.1 MIB II Description

MIB II acc. to RFC1213 is divided into the following groups:
