SNMP network management service
From a network management station, SNMP
(
Simple Network Management
Protocol)
is used to monitor and control all Ethernet architecture components and
thus ensure a rapid diagnosis in the event of a problem.
It is used to:
b
Interrogate network components such as computer stations, routers, switches,
bridges or terminal devices in order to view their status
b
Obtain statistics about the network to which the devices are connected
This network management software complies with the conventional client/server
model. However, to avoid confusion with other communication protocols that use this
terminology, we talk instead about:
b
ConneXview network diagnostics software TSX EAZ 01P SFE10
b
Network manager for the client application that operates on the computer station
b
SNMP agent for the network device server application
Transparent Ready products can be managed by any SNMP network manager,
including HP Openview and IBM Netview.
The SNMP
(
Simple Network Management Protocol)
standard protocol is used for
access to configuration and management objects that are contained in the device
MIBs (
Management Information Base
).
These MIBs must comply with certain
standards to be accessed by any managers on the market, but, depending on the
complexity of the products, manufacturers can add certain objects to private
databases.
The Transparent Ready private MIB includes management objects specific to the
Schneider Electric offer. These objects simplify installation, setup and maintenance
of Transparent Ready devices in an open environment using standard network
management tools.
Transparent Ready devices support 2 levels of SNMP network management:
b
The Standard MIB II interface: this interface accesses a first level of network
management. It enables the manager to identify the devices making up the
architecture and retrieve general information about the configuration and operation
of Ethernet Modbus/TCP interfaces.
b
The Transparent Ready MIB interface: this interface improves the management of
Transparent Ready devices. This MIB has a set of data enabling the network
management system to supervise all the Transparent Ready services.
The Transparent Ready MIB can be downloaded from the FTP server of any
Transparent Ready Ethernet module in a PLC.
