SNMP and Schneider Private MIB Overview
Overview Simple Network Management Protocol (SNMP) is configured on your NOE or
140 CPU 651 x0.
Introduction Network management software allows a network manager to:
z monitor and control network components
z isolate problems and find their causes
z query devices, such as a host computer(s), routers, switches, and bridges, to
determine their status
z obtain statistics about the networks to which they are attached
Simple Network
Management
Protocol
Your NOE module or 140 CPU 651 x0 controller supports the Simple Network
Management Protocol (SNMP), which is the standard protocol used to manage a
local area network (LAN). SNMP defines exactly how a manager communicates with
an agent.
The SNMP defines the format of:
z requests that a manager sends to an agent
z replies that the agent returns to the manager
MIB Each object to which SNMP has access must be defined and given a unique name.
Manager and agent programs must both agree on the names and meanings of the
fetch and store operations. The set of all objects SNMP can access is known as a
Management Information Base (MIB).
Private MIB Schneider obtained a private MIB, Groupe_Schneider (3833). Under the Groupe
Schneider private MIB is a Transparent Factory Ethernet (TFE) private MIB. The
Transparent Factory SNMP embedded component controls the Schneider private
MIB function.
