SNMP
4.3.5.1
To get detailed status information of the device SNMP can be used. SNMP communicates via UDP (port 161):
Supported SNMP commands:
- SNMPGET:
request status information
- SNMPGETNEXT: request the next status information
- SNMPSET:
request change of status
You will need a Network Management System, e.g. HP-Open View, OpenNMS, Nagios etc., or the command line tools of
NET-SNMP to request information via SNMP.
4.3.5.1.1 SNMP-communities
SNMP authentifies requests by so called communities.
The public community has to be added to SNMP-read-requests and the private community to SNMP write requests. You can
see the SNMP communites like read/write passwords. SNMP v1 and v2 transmit the communities without encryption. There-
fore it is simple to spy out these communities. We recommend to use a DMZ or IP ACL.
4.3.5.1.2 MIB
All information, that can be requested or changed, the so called „Managed Objects“, are described in „Management Informati-
on Bases“ (MIBs).
There are three MIBs, which can be requested from the unit:
„system“, „interface“
„system“ and „interface“ are standardized MIBs (MIB-II).
At least, there are so called Object Identifiers (OID) subordinated to those three structures. An OID describes the location of
an information inside a MIB.
4.3.5.1.3 SNMP-traps
SNMP-Traps are system messages, sent via SNMP-protocol to different clients. On following events a SNMP-Trap will be
dispatched:
Min/Max-Alerts from the sensors
