Configuration and diagnostics over SNMP

Configuration of an IE switch over SNMP
Using SNMP (Simple Network Management Protocol), a network management station can
configure and monitor SNMP-compliant nodes such as an IE switch. To allow this, a
management agent is installed on the node with which the management station exchanges
data using Get and Set requests. The IE switch supports SNMPvV1, SNMPv2, and
SNMPv3.
The configurable data is stored on the IE switch in a database known as the MIB
(Management Information Base) that is accessed by the management station or Web Based
Management.
SIMATIC NET SNMP OPC Server
The SNMP OPC server makes available the SNMP information from TCP/IP networks on the
IOPC interface with SNMP (Simple Network Management Protocol). With the aid of the
SNMP OPC server, any OPC client systems (such as WinCC) can now access diagnostic
and parameter data of SNMP-compliant components.

Non SNMP-compliant components can also be included in the plant visualization using their
IP addresses. This allows, for example not only simple device diagnostics but also detailed
information such as redundant network structures or network load distributions of entire
TCP/IP networks to be displayed. With the additional monitoring of this data, device failures
can be detected and localized quickly. This increases operational safety and improves plant
availability. You configure the devices to be monitored by the SNMP OPC server using
STEP 7 (as an alternative you can use NCM PC).
