SNMPv3 uses a more sophistic

1 while assigning a higher level of security to another group, granting
ific MIB. An additional layer of security is available for SNMPv3 in that SNMP messages may be
encrypted. To read more about how to configure SNMPv3 settings for the Switch read the next section.
Traps
itch generates traps
and sends them to the trap recipient (or network manager). Typical traps include trap messages for Authentication Failure,
Topology Change and Broadcast\Multicast Storm.
MIBs
Management and counter information are stored by the Switch in the Management Information Base (MIB). The Switch
uses the standard MIB-II Management Information Base module. Consequently, values for MIB objects can be retrieved
from any SNMP-based network management software. In addition to the standard MIB-II, the Switch also supports its own
proprietary enterprise MIB as an extended Management Information Base. The proprietary MIB may also be retrieved by
specifying the MIB Object Identifier. MIB values can be either read-only or read-write.
The DGS-3312SR incorporates a flexible SNMP management for the switching environment. SNMP managem be

The Switch allows groups of users to be listed and configured with a shared set of privileges. The SNMP version may also
be set for a listed group of SNMP managers. Thus, you may create a group of SNMP managers that are allowed to view
read-only information or receive traps using SNMPv
read/write privileges using SNMPv3.
Using SNMPv3 individual users or groups of SNMP managers can be allowed to perform or be restricted from performing
specific SNMP management functions. The functions allowed or restricted are defined using the Object Identifier (OID)

Traps are messages that alert network personnel of events that occur on the Switch. The events can be as serious as a
