bases (MIBs). MIBs describe the structure of the management data of a device and its subsystems. MIBs
use a hierarchical namespace containing object identifiers (OID). Each OID identifies a variable that can
be read through SNMP.
WMI
WMI is the Web-based Enterprise Management (WBEM) effort implementation by Microsoft. It is
implemented on the Microsoft Windows platforms. WMI supports CIM and Microsoft-specific CIM
extensions.
WMI includes:
• A powerful set of native services such as query-based information retrieval and event notification.
• Extensive scripting capabilities through the Windows Scripting Host (WSH).
• The CIMOM, which is the interface and manipulation point for CIM objects and information.
• The repository, where CIMOM stores management data.
In the Command | Monitor architecture, CIMOM and the repository are represented by the Microsoft WMI
Object Manager. The CIMOM is the interface and manipulation point for CIM objects and information.
CIMOM acts as a facilitator in gathering information and manipulating object properties. Microsoft has
implemented this component as the Windows management (winmgmt) service. The CIMOM is a software
middle layer that mediates interactions between high-level management applications and the low-level
instrumentation, such as Command | Monitor, and other providers. The CIMOM ensures that data
supplied by providers is presented to management applications in a uniform and provider-independent
way. The CIMOM does this by using the Component Object Model (COM) Application Programming
Interface (API).
The repository is a binary file where the CIMOM stores management data. The data includes information
from the compiled Managed Object Format (MOF) file(s), including the CIM class definitions, properties,
qualifiers, and hierarchical relationships. Instance data, as it becomes available, is also stored in the
repository.
WMI provides a scripting interface. Using VBScript or JScript, you can write scripts, connect to WMI
services locally or remotely, retrieve information, or run methods. You can script most of the Command |
Monitor tasks as Command | Monitor is implemented through WMI.
For more information on VBScript and sample scripts, see the Dell Command | Monitor Reference Guide
available at dell.com/clientsystemsmanagement.
For more information on WMI, see technet.microsoft.com.
NOTE: To connect remotely to WMI services, you must have Administrator privileges on both the
local and remote systems.
WSMAN
The WSMAN protocol is a DMTF open standard defining a Simple Object Access Protocol (SOAP)-based
protocol for managing servers, devices, applications, and web services. It uses data from CIMOM to
facilitate the management.
WSMAN is a protocol that provides an abstraction layer to access the CIM information. The reason is that
the console can use WSMAN to communicate with in-band or out-of-band systems to gather asset
