IPower 2x6
User Guide
Configuration - Syslog
Enable Syslog: You can select to have the syslog enabled
or disabled.
Syslog Server IP: If you enable the syslog you will need to
enter the IP address of the Syslog server.
Syslog Port: If syslog is enabled you will need to enter the
port number that your Syslog server uses to receive syslog
information.
IP Access Control List
The IP Access Control List (IP ACL) acts as an IP filter for your switch. Active hosts and subnets only can
contact the Switch if their IP addresses are stated in this IP ACL.
e.g.: "http://192.168.0.1" or "http://192.168.0.1/24"
If you locked yourself out by mistake, please activate bootloader mode of the Switch and start
Gbl_Conf.exe and deactivate IP ACL.
SNMP
To get detailed status information of IPower 2x6, SNMP can be used. SNMP communicates via UDP (port
161): You can also use SNMP to switch the power ports.
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, Open NMS, Nagios etc., or the
command line tools of NETSNMP to request information of IPower 2x6 via SNMP.
SNMP Communities
SNMP authenticates the requests from the named 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 communities like read/write passwords. SNMP v1 and v2 transmit the
communities without encryption. Therefore it is simple to spy out these communities. We recommend you
use a DMZ or IP ACL.
MIBs
All information that can be requested or changed, called "Managed Objects", are listed in "Management
Information Bases" (MIBs).
There are three MIBs, which can be requested from the IPower 2x6: "system", "interface" and
"powerports". "System" and "interface" are standardised MIBs (MIB-II). "Powerports" has been created
especially for IPower 2x6.
Object Identifiers (OID) describes the location of information inside an MIB.
SNMP-Traps
SNMP-Traps are system messages, sent via SNMP-protocol to different clients. On particular events,
IPower 2x6 will dispatch a SNMP-Trap:- Switching of the Power Ports.
Syslog
Syslog messages are simple text messages transmitted to a syslog server using UDP.
Linux OS regularly have a syslog daemon installed, e.g. syslog-ng. For Windows there are some freeware
tools available.
On following events, IPower 2x6 will send a syslog message:
- Booting up
- Activation/deactivation of syslog
- Switching of Power Ports
