FAQ EPM SNMP
General Remarks
SNMP can be used to retrieve status information from Expert Power Meter via UDP (port
161)
supported SNMP commands
SNMPGET : request status information
SNMPGETNEXT : request next status information
To scan Expert Power Meter via SNMP, you need a NetworkManagmentSystem like HP-
OpenView, OpenNMS, Nagios, etc... or simply the command line tools of NET-SNMP which
are also used in the examples below.
SNMP Communities
SNMP authenticates the network requests based on so-called communities named public
and private. The SNMP request must bei include the so-called public community in all status
queries (read-only access) and the public community for all change requests (writing access).
The SNMP communities serve as passwords for reading or writing. In SNMP versions v1 und
v2c, the communities are transmitted without encryption, and can easily be wiretapped
within the collision domain by IP sniffers. Therefore we strictly recommend to use SNMP
only within a Demilitarized Zone or with Expert Power Control's IP Access List IP-ACL
activated!
MIBs
The values that can be handled, called 'Managed Objects', are described in Management
Information Bases (kurz MIBs). Three different MIBs can be retrieved from Expert Power
Meter:
