Traps; Management Information Base (Mib) - D-Link DGS-1210/ME Series Hardware Installation Manual

DGS-1210/ME series Metro Ethernet Switch Hardware Installation Guide
describes what each user on that list can do as an SNMP manager.
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, a group of SNMP managers can be
created to view read-only information or receive traps using SNMP v1 while assigning a higher level of
security to another group, granting read/write privileges using SNMP v3.
Using SNMP v3 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) associated with a specific MIB. An additional layer of security is available for
SNMP v3 in that SNMP messages may be encrypted. To read more about how to configure SNMP v3
settings for the Switch read the section entitled Management.

Traps

Traps are messages that alert network personnel of events that occur on the Switch. The events can be as
serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change.
The Switch 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.

Management Information Base (MIB)

The Switch in the Management Information Base (MIB) stores management and counter information. 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.
