Snmp - Gude Expert Power Control NET 24x Manual

3.5 SNMP

To get detailed status information of EPC NET 24x SNMP can be
used. SNMP communicates via UDP (port 161) with EPC NET
24x: You can use SNMP to switch the power ports as well.
Supported SNMP commands:
- SNMPGET:
- SNMPGETNEXT:
- SNMPSET:
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 of EPC NET 24x via SNMP.
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. Therefore it is
simple to spy out these communities. We recommend to use a
DMZ or IP ACL.
MIBs
All information, that can be requested or changed, the so called
„Managed Objects", are descripted in „Management Information
Bases" (MIBs).
There are three MIBs, which can be requested from EPC NET 24x:
„system", „interface" and „powerports"
„system" and „interface" are standardised MIBs (MIB-II).
„powerports" (GUDEADS-EPC-MIB::gadsEPC) was created
especially for EPC NET 24x.
At least, there are so called Object Identifiers (OID) subordi-
nated to those three structures. An OID describes the location of
an information inside a MIB.
