Thank you for choosing the 3Com Desktop Management Interface (DMI) Agent, one of several advanced software management solutions from the world's leading supplier of desktop and workgroup networking solutions.

DMI is a management instrumentation standard drafted by the Desktop Management Task Force (DMTF), an industry-led organization that implements technology specifications to ensure open standards. DMI 2.0s (Desktop Management Interface - (s) Supports Secure Mode) is an instrumentation technology that has been widely accepted by all major hardware and software manufacturers to monitor and configure hardware and software devices. By installing the 3Com DMI Agent, any DMI 2.0-compliant management browser can access information such as the 3Com NIC driver version, size, statistics on number of packets sent, CRC receive errors, and much more. DMI also enables you to remotely configure software and hardware features such as Remote Wake Up, OS-absent alerts, and the 3Com Managed PC Boot Agent with a DMI-compatible browser.

As part of 3Com's DynamicAccess technology, the 3Com DMI Agent is one of many technologies that provide you with superior Managed PC solutions. Other applicable technologies include Advanced Power Management Interface (ACPI), Remote Wake Up (RWU) and Managed PC Boot Agent (MBA). Combining these Managed PC features with 3Com advanced management software such as the 3Com Edge Monitor Suite, gives you the most advanced network management solutions available on the market today.

This 3Com DMI Agent which replaces the previous version, is fully supported by 3Com Technical Support and meets the requirements of DMTF DMI 2.0 and 2.0S specifications, as well as PC98, PC99, and WfM (Wired for Management) v 1.1a and 2.0 specifications. You can download the latest 3Com DMI Agents from the 3Com Managed PC web site: https://www.3com.com/managedpc

The features available in the 3Com DMI Agent fall into 2 categories - basic and extended. The basic features are implemented on all full-featured 3Com NICs and meet the standards for PC99 and WfM 2.0 compliance, as well as those supplied by PC OEM vendors. The 3Com DMI Agent is not currently supported on the OfficeConnect family of NICs.

Secure DMI Support

The 3Com DMI Agent supports secure connectivity between the DMI browser and local Service Provider in conjunction with the DMI Agent. This security is provided by Remote Procedure Call (RPC) and must reside within the software browser. Refer to your DMI management application documentation for instructions on how to install RPC.

Supports Dynamic NIC Insertion and Removal

When you dynamically insert or remove the NIC without turning off the PC ("hot swapping") from a notebook PC running Windows 95 or Windows 98, the 3Com DMI Agent automatically adds or removes the component from the Service Provider.

Multiple NIC Support

Most 3Com NICs are instrumented for the 3Com DMI Agent. Multi-NIC support enables DMI browsers to display the attributes of more than one 3Com NIC in a PC or PC server.

Support for Extended Features of 3Com NICs

Apart from supporting the standard DMTF MIF group, the 3Com DMI Agent can manage extended NIC features such as configuration of a 3Com BootROM, the configuration of Remote Wake-Up, alerts, and keep-alive features of Managed NICs. The 3Com DMI Agent generates a Management Information Format (MIF) file that contains information about the NIC. DMI uses the information from the MIF to manage the PC. Refer to the table below for the location of additional information:

Extended Features	Appendix
Keep-Alive	Appendix E
Remote Wake Up	Appendix F
Remote System Alert Configuration	Appendix G

Automatic MIF Generation

The 3Com DMI Agent dynamically builds a MIF file before registering with the DMI Service Provider. The NIC-specific MIF ensures that irrelevant groups of information are not forwarded to the network management application.

The MIF content is based on the capabilities of the NIC driver found on the system. For example, if a NIC with a remote wake up feature is found, all groups related to remote wake up will be included in the MIF for that particular NIC.

The figure below displays some supported objects.

Preserve Integrity of MIF Database on 3Com Components

Some DMI management applications support manual manipulation of the MIF database. This capability allows you to add or delete components, groups, or attributes from the MIF database. Be careful if you directly edit the MIF database, because you can corrupt it by adding irrelevant information or deleting important components. The 3Com DMI Agent handles this potential problem by verifying the information on the MIF database upon start up. If a mismatch is found, the 3Com components in the MIF database are rebuilt to reflect what is on the system.

Fully Compliant with DMI v2.0 Specification

The 3Com DMI Agent has been tested and evaluated with the test plan issued by the DMTF. You can find information on the DMTF and DMI 2.0s specifications on the DMTF web site: https://www.dmtf.org

Fully Compliant with Wired for Management 2.0 Specification and PC99

The 3Com DMI Agent satisfies all the DMI-related requirements specified in the WfM 2.0 specification. For information on the WfM 2.0 specification, see the following Intel developer web site: https://developer.intel.com/ial/wfm/wfmspecs.htm. In addition, this support is required by the management capabilities of the PC99 specification developed by Intel and Microsoft and adhered to by PC manufacturers and OEMs.

In this section you can find the information necessary to plan your deployment of the 3Com DMI Agent.

Your network management station requires a DMI-compatible browser or a network management application that supports DMI 2.0 or 2.0s browsers, such as:

Hewlett Packard TopTools

Tivoli Management Suite

Dell OpenManageT Administrator version 4.3 (clean installations only, for details see Tech Tips.) or IT Assistant

Compaq Insight Manager Management Station

Intel LANDesk Client Manager

If you have deployed any previous 3Com DMI Agent, this new release automatically removes any legacy 3Com agents during installation.

Your PC requires the following items to use the 3Com DMI Agent:

A full-featured 3Com NIC, properly installed

DMI Service Provider 2.0 or greater (such as Smart Technologies Service Provider 2.0)

NDIS 3, 4, or 5 driver

Windows 95, Windows 98, or Windows NT, using the appropriate Service Pack listed below:

Windows 95 Retail Service Pack 1 or OEM Service Release (OSR) 2

Windows 98 retail release

Windows NT 4.0 Service Pack 3 or above

Windows NT 3.51 Service Pack 5

Windows 2000

For installation, a minimum of 2.5MB free hard drive space is required.

The 3Com DMI Agent installation process can be done at each end node or it can be done from a central location, eliminating the need to touch end node PCs.

The distribution methods are:

Distribute the 3Com DMI Agent installation program from a login script or a software distribution system that you have.

Have each end user download the 3Com DMI Agent from a network or intranet server. After installing the software and rebooting, the 3Com DMI Agent should be running properly.

This initial installation and configuration process is the same one you would use for a local node installation. For installation details, refer to Chapter 2.

The 3Com DMI Agent software installation program detects whether you have previously installed any 3Com DMI Agent software on a PC. If any previous software version is detected, the installation program removes it, and then installs this current version. Because the installation program checks for the presence of the current 3Com DMI Agent software, any subsequent time users log on to the network, the installation program does not reinstall the 3Com DMI Agent software.

You should not leave the installation and configuration files in your login script files any longer than you need to be satisfied that each end node has completed the installation.

You can obtain the 3Com DMI Agent for download from the 3Com Managed PC Web site https://www.3com.com/managedpc . Be sure to check this site for the latest information and FAQs regarding the 3Com DMI Agent.

This chapter describes how you can install and remove the 3Com DMI Agent on PCs running Windows 95, 98, Windows NT or Windows 2000. The 3Com DMI Agent comes with an installation program to automate the process. You can perform unattended and attended installations. These tasks do not interfere or conflict with any other agents or intermediate drivers that may be already installed on the PC. For unattended installation, you can use a batch file with a command line switch that supplies responses normally given interactively.

This section shows you how to install the 3Com DMI Agent on your PC running Windows 9X or NT 4.X. To install the 3Com DMI Agent on a PC running Windows NT 3.51, see the section Using_the_3Com_DMI_Agent_on_NT_3.51.

After you have obtained the 3Com DMI Agent files from the web or other 3Com media, follow the procedure below. If you are installing the 3Com DMI Agent from the EtherCD, follow the navigation provided on the CD.

Before performing any of the installation or removal steps on a Windows NT system, you must log on to the PC with an account that has system administration privileges.

To install the 3Com DMI Agent:

Double-click the 3COMDMI.EXE file.

Select Install 3Com Software and click Next.

Read and accept the License Agreement.

You will see the progress indicator on the screen.

Once complete, a message appears stating: 3Com DMI Agent Installation Completed Successfully.

If you use an unattended installation process no completion message appears.

Restart the system when instructed to do so.

You can verify that the 3Com DMI Agent is correctly installed using several methods.

Use a DMI management application to verify that the 3Com NIC component is present. The name of the component is 3Com Network Interface Card.

For both Windows 9x and NT, the agent is installed in the following folder:

<windows system directory>\3com_dmi directory.

where <windows system directory> is the installed directory for Windows.
For example, on Windows 95 the system directory may be c:\windows or on Windows NT, the system directory may be c:\winnt4\system32

In the Control Panel, you can verify that the 3Com DMI entry exists in the Add/Remove Program applet, as shown in the next figure.

If you do not see any information on the 3Com NIC after installing the 3Com DMI Agent:

Verify that your DMI management application is DMI 2.0 or DMI 2.0s compliant. You can check the application documentation or the vendor's web site for this information. The 3Com DMI Agent does not work with DMI 1.x-compliant management applications.

Verify that your PC configuration meets all the requirements listed in this User Guide.

If you receive an error on a PC running Windows NT, check the event log for error messages.

The unattended method of installing the 3Com DMI Agent works only on PCs running Windows9X and Windows NT 4.0.

For unattended mode, at a DOS prompt, type:

3ComDMI -s -a -s -f1setup.iss

This command uses the same program for unattended install that is used for regular installation.

Inform your user community about the changes you are making that they will see when they log in to your network. The network login process pauses until the DMI Agent installation is complete. Your users will see the network bindings window appear. No user intervention is required.

You should not leave the installation and configuration files in your login script files any longer than you need to be satisfied that each end node has completed the installation.

For NetWare, use the NetAdmin tool to modify a login script to include the 3Com DMI Agent file using the unattended installation mode.   

For Windows NT networks, add a batch file. Use the User Manager for Domain to add this batch file to the login script.

The installation program does not completely install the 3Com DMI Agent on PCs running Windows NT 3.51. Once properly installed, the 3Com DMI Agent accurately reports DMI data. Follow the steps below to ensure a proper installation:

Double-click the 3COMDMI.EXE file to complete the first portion of the installation.

Go to the Network Settings in the Control Panel.

Select Add Software.

Click Other.

Click Continue.

Windows prompts for a disk or the path to an .INF file.

Type:

c:\<windows system directory>\3com_dmi

where <windows system directory> is the installed directory for Windows.
For example, if the system directory is c:\winnt351\system32, enter:

c:\winnt351\system32\3com_dmi

Windows displays 3Com BCAITDI DMI TDI.

Click OK.

Click OK in the Network Settings applet in Control Panel.

Reboot your PC.

To remove the 3Com DMI Agent:

Go to the Network Settings applet in the Control Panel.

In the Installed Network Software list, select 3Com BCAITDI DMI TDI.

Click Remove.

Click OK to exit the Network Settings applet in the Control Panel.

Run <windows system directory>\3com_dmi\undmint.exe.

Reboot the PC.

This section shows you how to remove the 3Com DMI Agent from your PCs running Windows 9X or Windows NT 4.0.

Open the Control Panel.

Click Add/Remove Programs.

Select 3Com DMI Agent and click Remove.

There will be a message box indicating if uninstall is successful.

Reboot the system immediately.

You can use any DMI 2.0-compliant management application to view the attributes displayed by the 3Com DMI Agent. You can also use an SNMP console to query the same information.

The SNMP console can query or set all the information available through the 3Com DMI Agent.

To use the SNMP console:

Make sure you have a functional DMI platform with the 3Com DMI Agent installed. Minimally, a DMI 2.0 Service Provider and 3Com DMI Agent must be installed.

Install a DMI-SNMP mapper (provided with your DMI management application, or a mapper can be ordered through Smart Technologies Enablers, Inc.).

Install the Microsoft SNMP agent through the Network Control Panel applet. For Windows NT, the SNMP agent needs to be configured to match your SNMP settings (community and destination trap address).

Have a functional SNMP console such as HP OpenView Network Node Manager.

Compile the nic-3com.mib file into the SNMP Console environment. The MIB file, nic-3com.mib can be found in the <windows system directory>\3Com DMI directory. The SNMP Console should have an SNMP browser module which allows you to perform gets and sets on the 3Com DMI Agent.

DMI-SNMP Mapper Architecture

There are two ranges of features that may be available on your full-featured 3Com NIC: basic or extended. The basic features are available for all full-featured 3Com NICs, while extended features are available for newer management NICs. You can gather standard DMI 2.0 statistics with the 3Com DMI Agent, such as NIC identification, node address, MAC address, or driver version.

The 3Com DMI Agent supports additional NIC features such as:

MBA configuration

Remote Wake-Up configuration

Keep-Alive configuration

Remote System Alert, also called Platform Event Trap (PETs) configuration

Please refer to the NIC user guide for details about the features that are supported. The complete set of supported attributes is described in the appendices of this User Guide, as indicated in the table below.

These tech tips are provided to assist you with using the 3Com DMI Agent on various platforms or specific configurations.

Tip 1 - Installing the 3Com DMI Agent on a Dell OpenManage Client PC

If plan to install the 3Com DMI Agent on a PC that has been upgraded from Dell OpenManage Client Version 4.2 or earlier to version 4.3, the 3Com DMI Agent does not function properly because of an incomplete upgrade process. To use the 3Com DMI Agent on an upgraded PC, follow the steps below:

Stop all DMI programs including Dell OpenManage and the 3Com DMI Agent.

On an NT PC, the 3Com DMI Agent is a service and can be stopped through the Service Control Manager in the Control Panel.

On a Win9X PC, stop the 3Com DMI Agent using the steps below:

1. Press Ctrl+Alt+Del to open the Close Program window.
2. Select the 3CDMINIC.EXE.
3. Click End Task.

Go to the windows system directory.

Rename the following files to a different name:

WCDMI.DLL
WDIMUTIL.DLL
WCDMIDCE.DLL

provided no other application is using these DLLs.

Reboot the PC.

Restart Dell OpenManage or complete the installation of the Dell OpenManage Administrator.

The 3Com NIC now appears as a manageable DMI component.

Tip 2 - Some PCs running Windows NT 4 and DMI Reporting

On some PCs running Windows NT 4.0, you may notice that DMI attribute data does not appear immediately upon each reboot only. The data does appear in the DMI browser after a slight delay of up to four minutes. Until the next reboot, the data is continuously reported.
