In order to recognize this change directly, the "Notification" area in the MIB table has
been moved from sysObjectID.0 to sysObjectID.3. This way, unidentified events are
generated until the new MIB table is imported. For compatibility reasons, SNMP v1
traps are created in the same way as before.

NET-SNMP

NET-SNMP provides a very widespread collection of SNMP command-line tools (snm-
pget, snmpset, snmpwalk etc.) NET-SNMP is among others available for Linux and
Windows. After installing NET-SNMP you should create the device-specific MIB of the
device in NET-SMP share directory, e.g. after

c:\usr\share\snmp\mibs

or

/usr/share/snmp/mibs

So later you can use the 'subtree names' instead of OIDs:

Name:

snmpwalk -v2c -mALL -c public 192.168.1.232 gudeads

OID:

snmpwalk -v2c -mALL -c public 192.168.1.232 1.3.6.1.4.1.28507

NET-SNMP Examples

Query Power Port 1 switching state:

snmpget -v2c -mALL -c public 192.168.1.232 epc822XPortState.1

Switch on Power Port 1:

snmpset -v2c -mALL -c private 192.168.1.232 epc822XPortState.1 integer 1

4.6.1

Device MIB 2302

Below is a table of all device-specific OID 's which can be accessed via SNMP. In the
numerical representation of the OID the prefix " 1.3.6.1.4.1.28507 " (Gude Enterprise
OID) was omitted at each entry in the table to preserve space. The example for a com-
plete OID would be "1.3.6.1.4.1.28507.70.1.1.1.1". A distinction is made in SNMP OID
's in between tables and scalars. OID scalar have the extension ".0" and only specify a
value. In SNMP tables the "x" is replaced by an index (1 or greater) to address a value
from the table.
