3.4 IP Access Control List
IP Access Control List (IP ACL) acts as an IP filter for your
EPC
NET 8x
. Wether it is active hosts and subnets only can contact
EPC NET 8x
, if their IP adresses 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 the boot-
loader mode of
EPC NET 8x
, start
Gbl_Conf.exe
and deactivate
IP ACL.
You can find more information about configuration of IP ACL in
chapter 3.3 or have a look at
http://www.gude.info/wiki
.
3.5 SNMP
To get detailed status information of
EPC NET 8x
SNMP can be
used. SNMP communicates via UDP (port 161) with
EPC NET
8x
: You can use SNMP to switch the power ports as well.
Supported SNMP commands:
- SNMPGET:
request status information
- SNMPGETNEXT: request the next status information
- SNMPSET :
EPC NET 8x
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 of
EPC NET 8x
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.
