MIB Object Types
MIB Object Types |
|
The Windows 2000 SNMP agent has a modular, extensible design that supports multiple MIBs through an agent application programming interface (API). The Windows 2000 SNMP agent is also known as the extensible agent, whereas the supported MIB objects are also known as SNMP subagents or extension-agents. When the SNMP service is started, the SNMP agent loads any SNMP extension - agent dynamic-link libraries (DLLs) that are configured in the registry. This design makes it possible to add new MIBs easily. Microsoft and third-party developers can develop MIBs for new hardware and software components and integrate them easily into an existing SNMP service.
When the SNMP service is started, each agent sends the object identifier for the base object in its MIB to the management system. This allows the management system to identify what managed objects are actually installed on each agent when the manager submits requests for information.
Table G.1 identifies the Windows 2000–based MIBs and the base object from which all other objects in the MIB are derived. The DLLs for MIB-II, LAN Manager MIB-II, and the Host Resources MIBs are installed with the SNMP service. The other MIBs listed in this table are installed when their respective services are installed.

In addition to being configured in the registry of the SNMP agent, new MIB objects must also be registered in the SNMP management software application on the management system. For more information about registering new MIB objects in the manager, see the documentation included with your management software application.
