3.1.8 Configuration of SNMP
The Simple Network Management Protocol (SNMP) is responsible for the
transport of control data, which enables the exchange of management
information, status and statistical data between individual network
components and a management system. Version 1 of the protocol is supported.
SNMP represents a standard for the management of devices in a TCP/IP
network. An SNMP management workstation polls the SNMP agent in order
to obtain information on the corresponding devices. Components of a device,
which the SNMP agent can access or an SNMP agent can modify, are
described as SNMP objects. Collections of SNMP objects are contained in a
logical database, the Management Information Base (MIB), and the objects
are frequently referred to as MIB objects.
In the ETHERNET coupler/controller, SNMP embraces the common MIB as
described in RFC1213 (MIB II).
The configuration of SNMP is done via the web-based management system
under the “Snmp” link or directly via SNMP.
On the web page stored in the coupler/controller, the name of the device
(sysName), the description of the device (sysDescription), the location
(sysLocation) and the contact person (sysContact) can be freely set.
In addition, up to 2 trap managers can be specified.
The SNMP is executed via Port 161. The port number for SNMP traps is 162.
This port number cannot be changed.
