Chapter 1 - Product OverviewChapter 1 - Product Overview

What is the DynamicWhat is the DynamicAccess Access network performance managernetwork performance manager 2.0?2.0?

The DynamicAccess network performance manager 2.0 (NPM) is part of the 3Com DynamicAccess technology family of endstation/server-based monitoring and management products. Its software-based approach gathers data directly from the endstations (desktops and servers) around the network to provide a single source for application performance data, network performance data, system health information, and network performance management.

Using the DynamicAccess LAN agents running on endstations, the NPM collects full performance data at its source. Using this data, application response times and system metrics are tracked and correlated with network performance data to determine whether the source of problems is the network, desktop, server, or application. The combination of software monitoring with NIC-generated data provides a continuous flow of application performance data. This data is immediately available to network administrators, allowing them a cost-effective, highly efficient method of quickly pinpointing problem causes so the correct network management tools can be applied.

The DynamicAccess network performance manager 2.0 offers many tools to obtain a real-time view of the traffic on your network from each endstation that has DynamicAccess LAN agent software installed. This version of the NPM does not collect data from an endstation connected to the LAN using dial-up networking.

DynamicAccess network performance manager 2.0 is composed of DynamicAccess LAN agent 2.0 and DynamicAccess browser view.

DynamicAccess LAN agent 2.0

DynamicAccess LAN agent 2.0 operates on all 3Com Ethernet, Fast Ethernet, and Gigabit Ethernet NICs, as well as any Microsoft-certified third party NICs installed on both desktops and servers. The DynamicAccess LAN agent 2.0 is licensed for unlimited use on all applicable 3Com NICs. For non-3Com NICs, you can purchase a license for the appropriate number of non-3Com supported NICs.

DynamicAccess browser view

You can view the data collected by the NPM using a Java-enabled Web browser, or you can retrieve the data with any SNMP-based network management application such as Transcend Traffix™ Manager or HP OpenView for further correlation and analysis. From anywhere on your network, even remotely, you can securely log in to the NPM to see charts, graphs, and tables of the statistics you need most. You can view alarm settings, capture packet data, view event logs, and view system health information. You can also set up or modify the NPM's current configuration.

Tech TipsTech Tips

Below are some of the anomalies and their solutions discovered during the testing of this product.

Tech Tip 1

SSYMPTOMYMPTOM: : When viewing graphs in browser view you notice some anomalies.

SSOLUTIONOLUTION:: The browser view is best observed using Microsoft Internet Explorer 5.01 (or later) on any PC.

Tech Tip 2

SSYMPTOMYMPTOM: : Your endstations with the DynamicAccess LAN agent installed that have VLANs enabled do not see each other.

SSOLUTIONOLUTION:: Check to see if these systems are running only the NetBEUI protocol. On PCs that use only the NetBEUI protocol you cannot enable VLANs due to the characteristics of that protocol.


Tech Tip 3

PPROBLEMROBLEM: : You want to create a shortcut to the NPM URL.

SSOLUTIONOLUTION:: Create a new file called NPM.HTML and insert the following contents into the file:

<HTML>

<HEAD>

<META HTTP-EQUIV="Refresh" Content="O; url=http://10.20.5.130/3Com/webview/ui/drmon2.html">

</HEAD>

</HTML>

NOTE:NOTE: Be sure to replace the URL string above with your URL string. Then place the NPM.HTML file into your IIS root directory.

Tech Tip 4

SSYMPTOMYMPTOM: : Not all of the installed protocols appear in the NPM lists.

SSOLUTIONOLUTION:: Due to the characteristics of non-routable protocols, such as NetBEUI and others below layer 3, these protocols will not appear in the graphs or screens that display network protocols or network addresses.

Removing the NPMRemoving the NPM

You can remove the NPM software using the Add/Remove Programs icon in the Control Panel. Previous versions of DynamicAccess software allowed you to remove the software by selecting the DynamicAccess PassThru Driver Transport located in the network control panel and clicking the Remove button.

Configuring the DynamicConfiguring the DynamicAccessAccess LAN agent LAN agent

Once the LAN agent is installed, you may want to set options in the DynamicAccess LAN agent that are specific to your site. One of these options is to enable secure monitoring such as packet filtering capture or traffic prioritization or other settings controllable in the DynamicAccess control panel.

Setting a Secure Monitoring Password for the DynamicSetting a Secure Monitoring Password for the DynamicAccessAccess LAN agent LAN agent

To enable secure monitoring and packet capture and filter capabilities with the NPM, you must set a password for the DynamicAccess LAN agent, using the SETPASS.EXE utility found in the following directory on the product CD:

Cd_drive:\DASetup\

You will first need to create a file that contains your selected password in encrypted form. You can create this file on your local administrator machine and later copy it to the appropriate server for use by others.

To create an Encrypted Password File:

1. Copy the SETPASS.EXE file to the hard drive of a your computer, for example c:\working.

2. Run SETPASS.EXE in the following manner:

c:\working\SETPASS.EXE -F file.ext password

where

-F indicates that the given password will be encrypted and saved into file.ext.

file.ext name of a file (with or without a full path) in which to store the encrypted password. File name can have any extension, which is optional.

password text password containing no spaces.

NNOTEOTE:: If no path is specified for file.ext (just the file name) file.ext will be located in the same directory where the SETPASS.EXE utility resides.


This procedure enables you to have your password saved in an encrypted format in a file for you to use in the instructions for your DynamicAccess LAN agents on your endstations.

Running SETPASS.EXE Locally Running SETPASS.EXE Locally

You can run the following on a local machine:

1. Copy the SETPASS.EXE file to the hard drive of a your computer, for example c:\temp.

2. Copy the file.ext you created on your administrator machine to the same directory.

NNOTEOTE:: If no path is specified for file.ext (just the file name) file.ext will be located in the same directory where the SETPASS.EXE utility resides.

3. Run SETPASS.EXE in the following manner. For example, if SETPASS.EXE is located in the c:\temp directory of the Sam_server system and it is run with the following arguments then this command:

c:\temp\SETPASS. EXE -SA file.ext

where

-SA indicates that the encrypted password from file.ext will be stored on the PC where the DynamicAccess LAN agent is installed.

file.ext is the name of a file (with or without a full path) that contains the encrypted password created in "Setting a Secure Monitoring Password for the DynamicAccess LAN agent."

will create or overwrite any previously existing file.ext file and save the encrypted password in it.

Running SETPASS.EXE in a Login Script Running SETPASS.EXE in a Login Script

You can edit or create a login script that is executed every time users of the DynamicAccess LAN agents log in to the server so that the endstations can get the proper password. The script should include the following call to:

<network_path>\SETPASS.EXE -SA file.ext

where

<network_path>\ is where you copied the SETPASS.EXE file to on the network server.

-SA indicates that the encrypted password from file.ext will be stored on the PC where the DynamicAccess LAN agent is installed.

file.ext is the name of a file (with or without a full path) that contains the encrypted password already created in "Setting a Secure MonitoringPassword for the DynamicAccess LAN agent".

NNOTEOTE:: If file.ext is not located in the same directory with SETPASS.EXE, you must specify the complete path for file.ext.

This step transfers the encrypted password to the DynamicAccess LAN agents, when the user logs in to the server and executes the login script.


For example:

\\Sam_server\c\working\SETPASS.EXE -SA \\Sam_server\c\passwords\file.ext

NOTENOTE: You can map the network path to a server to a drive letter, which might result in a simpler, more concise script.

The SETPASS.EXE utility's return value can be evaluated to ensure successful execution.

Return Value

Definition

0 Error reading/writing to/from a file or registry

1 Successful completion

2 Incorrect input parameters

After you are sure that all the endstations have run the script, you may remove it from the login sequence. If you need to change the password, you can use the same procedure for a new file.ext with the new encrypted password. If you do change the password, remember to update the NPM’s password as well.

Saving Settings to an .INI FileSaving Settings to an .INI File

After you have established the Traffic Prioritization and other settings for your site in the DynamicAccess control panel, you can save those settings for the currently selected NIC to a file which has a .INI file format. In the Apply Changes area of the Advanced Settings page, select Save the file To DynamicAccess software .INI. This file is used with DA15CFG.EXE to pass those site-specific settings to the endstations in your network through a login script or if DA15CFG.EXE is run locally.

NOTE:NOTE: Do not edit the .INI file directly to avoid inserting syntax errors that may prevent the file from being used properly.

Installing Other Third Party Networking SoftwareInstalling Other Third Party Networking Software

You may experience problems in cases where DynamicAccess LAN agent is already present and third parting networking software is being installed with its own installation utility rather than with the Network Control Panel. Examples of such networking software include Novell Client 32 and 3Com EtherLink 10/100 Mbps Desktop NIC (3C905C-TX-M) which come with their own installer utilities. 3Com recommends the following two installation options:

Option One

If the product can also be installed using the Network Control Panel, we recommend that you do so and not use the installation utility that was provided with that product.

Option Two

1. Uninstall DynamicAccess 2.0 software.

2. Reboot the system.


3. Install the third-party product.


5. Reinstall DynamicAccess 2.0 software.


7. Reapply SP6a.

Known Incompatibilities for the DynamicKnown Incompatibilities for the DynamicAccessAccess LAN agent LAN agent

SystemSoft CardWizardSystemSoft CardWizard

The DynamicAccess LAN agent 2.0 should not be installed on any NT machine that uses SystemSoft CardWizard. You will lose your network connection after rebooting.

Shomiti Packet BlasterShomiti Packet Blaster

For Shomiti Packet Blaster and similar products that operate directly with the NIC, the DynamicAccess LAN agent does not intercept the traffic generated by Shomiti from the source machine and thus, none of the data for this traffic will be recorded.

Intermediate Drivers

The 3Com DynamicAccess LAN agent 2.0 on Windows NT is based on Microsoft intermediate driver technology. Due to differences in vendors' implementations, certain intermediate drivers may not function properly in combination with others. If you use any intermediate driver technology, we recommend that you test the 3Com DynamicAccess LAN agent 2.0 with other technology you use at your site before you widely deploy the DynamicAccess LAN agent 2.0 on your Windows NT systems that have other intermediate drivers installed.

Also note that the 3Com DynamicAccess LAN agent 2.0 is not compatible with other 3Com DynamicAccess releases, such as those containing advanced server features and LAN encryption software features. Compatibility between these feature sets will be provided in future releases.

NetShow Theater Server 3.0NetShow Theater Server 3.0

If Microsoft NetShow Theater and the DynamicAccess LAN agent 2.0 are installed on the same computer, prioritization and performance monitoring will not be available. We recommend using Windows Media Technologies (MPEG-4) instead if you want prioritization and application monitoring of media traffic.

RIP Protocol for IPX/SPX ServicesRIP Protocol for IPX/SPX Services

The DynamicAccess LAN agent 2.0 should not be installed on your Windows NT 4.0 server if you are using Routing Information Protocol (RIP) for IPX/SPX Services with multiple segments.

Distributing and Installing the DynamicDistributing and Installing the DynamicAccessAccess LAN agent LAN agent from Your Serverfrom Your Server

After you have completed an initial installation of the DynamicAccess LAN agent and have determined and saved the site-specific settings that you need into a .INI file, you can turn to making the DynamicAccess LAN agent available for installation on your endstations. You can


have your end users or additional administrators assist you in distributing the DynamicAccess LAN agent to your endstations from a server.

Complete these basic instructions in the following sections to set up your server with the appropriate DynamicAccess LAN agent installation files. Also, review the steps required for the installation of the DynamicAccess LAN agent on the Windows 95, Windows 98 and NT platforms before deploying the agents as described below. You can also inform your user community or assisting team about the steps to install the DynamicAccess LAN agent on the endstations. These steps include running the DynamicAccess LAN agent setup program, the SETPASS.EXE utility, and the DAI5CFG.EXE utility to complete the configuration of the DynamicAccess LAN agent. For your end users’ ease of use, you might consider including SETPASS.EXE utility and the DAI5CFG.EXE utility into a single batch file.

To Prepare the Server:

You can have the setup image reside in a directory on a server, or on a CD in the server’s CD-ROM drive.

NOTE: The path name to the setup image cannot contain any spaces.

For the following example, assume that you have:

Installed the DynamicAccess LAN agent on a target system and have created a configuration .INI file and created the .bin password file.

Server named MY_Server.

Created a shared directory, d:\InstallDir on MY_Server.

1. Verify a directory for the setup image of the DynamicAccess LAN agent, such as d:\InstallDir. This path name cannot contain any spaces.

2. Enable the Access Type permissions on the shared InstallDir to be Read-only and include Everyone.

3. Copy the directories and files from the DynamicAccess 2.0 CD to the d:\InstallDir on MY_Server. The complete structure is required.

4. Copy the configuration .INI file you saved earlier to use with DA15CFG.EXE to the d:\InstallDir on MY_Server.

5. Your batch file (DA20BAT) could consist of the following commands:

@echo off

\\MY_Server\d\InstallDir\setpass.exe -SA \\MY_Server\d\InstallDir\file.ext

\\MY_Server\d\InstallDir\DA15CFG.EXE -F \\MY_Server\d\InstallDir\settings.ini

You may choose to send out instructions to the people who will complete the installation, similar to the following sample, making sure that you specify the settings for your server.

Chapter 5 – Configuring the DynamicChapter 5 – Configuring the DynamicAccess Access network network performance managerperformance manager

This chapter describes how to configure the NPM to monitor specific segments on the network, and how to set access permissions for filter and capture to ensure that only authorized users have access to the obtained data.

Configuring NPM General Information SegmentsConfiguring NPM General Information Segments

Minimally, you need to configure at least one polling segment definition, using the options in the NPM setup screen.Point your Web browser at the NPM server using its name or IP address to view the initial page. Now you need to configure the NPM server to monitor specific segments on the network so it can poll the DynamicAccess LAN agent to collect data.

NNOTEOTE:: If this is not your initial time configuring the NPM, be aware that other users may also be modifying the settings on these screens. To avoid change conflicts, we recommend you click the browser view’s Refresh Data button frequently.

1. To configure the NPM server, click the Setup icon from the navigation bar.

2. Select the General tab.

3. To enable security over packet capture and filter capabilities with the NPM, a password is used by the NPM and the DynamicAccess LAN agent. This password must be the same one you used to configure the DynamicAccess LAN agent with the SETPASS.EXE utility. If you did not enter a password during the installation of the NPM and DynamicAccess LAN agent software, you can set the password now. Type and confirm the password. Click Apply.

4. Leave the Enable Local LAN Agent Polling box deselected, unless you want to collect monitoring data from this local agent.

The NPM has a local DynamicAccess LAN agent and normally you would not want or need to collect monitoring data from this agent. If you select this option to collect monitoring data from this local agent, the NPM will see and process poll responses from the local agent and the NPM’s database will eventually become filled with meaningless host matrix information. This extra processing will reduce the performance of the NPM server and also populate the address map table with meaningless entries which, in some cases, will obscure some of the data being collected from the other LAN agents. 3Com recommends, therefore, that you do not activate this option.

If you need or want to see monitoring results for traffic on the NPM’s own LAN segment from the perspective of the NPM server, check this option. 3Com recommends that you either deactivate polling on all segment other than the NPM’s local segment or that you do a Warm Reset of the NPM to purge the NPM database of any meaningless host matrix data that was collected while this feature was enabled when you are done collecting data from the NPM’s local LAN agent. 3Com advises that you deselect this option when you no longer need to track this data.

Configuring NPM SegmentsConfiguring NPM Segments

This section describes how to configure the NPM to monitor specific segments on the network.

1. In the Segment tab, click Add to specify a segment for the NPM.


2. Enter the segment information. The segment configuration screen for adding a new subnet or for editing the configuration of a subnet varies according to the protocol selected. The default is IP. The other panels display subnet ID, subnet mask, and the polling type and rate. For example, you could create an IP-based poll segment using subnet ID 177.85.145.0 and a mask of 255.255.252.0.

NOTE: NOTE: If you select Directed Multicast and the NPM server has more than one NIC installed, the segment will be monitored using IP multicast only if it can be reached from the first NIC of the NPM machine. You will then have the option to go ahead with the selection, or cancel it and change the segment configuration.

3. Select the LAN Agent Licensing tab. The LAN agent is supplied free of charge with 3Com NICs, or from this CD or the 3Com Web site. However, you need a license to use the LAN agent on non-3Com NICs. You can purchase the license by contacting your VAR or through your local 3Com account representative. To find a 3Com office listing please go to http://www.3com.com/global/world/ or call 1-800-NET-3Com.. Enter the license number and click Apply. Current licenses and the number of NICs covered by each license will be displayed in the panel below.

4. Enter the LAN Agent license number and click Apply. Current licenses and the number of NICs covered by each license will be displayed in the Current Licenses box.



5. Select the NPM Licensing tab.

6. Enter the NPM license and click Apply. You must have a license for the NMP to collect data. Please be aware that the evaluation copy will only work for 45 days, after which the NPM stops collecting data. You can obtain a license for the NPM by contacting your normal VAR or through your local 3Com account representative. To find a 3Com office listing please go to http://www.3com.com/global/world/ or call 1-800-NET-3Com.

Setting Access Permissions for Filter and CaptureSetting Access Permissions for Filter and Capture

If you installed the NPM on an NTFS partition, you can ensure that only authorized users have access to the data obtained by filter and capture by setting access restrictions on the appropriate directories. If the computer participates in a domain, you can also add user accounts and global groups from that domain and from trusted domains. You must have administrative privileges to set access restrictions. You can add user accounts from the local computer by completing the following basic procedure. For details, refer to the online help for Windows NT.

1. From User Manager, create a new Local Group.

2. In Group Name, type a name for the new group, such as NPM Admins.

3. In Description, type a description of the new group, such as Can filter and capture data.

4. Click Add to add members to the local group, and then complete the Add Users and Groups dialog box.

Next find the directories under the NPM IIS root that you want to restrict. For example, $install directory$/ui/Capture.

1. In the Windows Explorer, right-click on the directory name and click Sharing.

5. Select Shared As.



6. Click Permissions to open the Access through Share Permissions dialog box.

7. Click Add, and in the Add Users or Groups dialog, select the group you created, such as NPM Admins. If you do not see the group, you may need to select a different domain or machine from the List Names From field.

8. Click Add and select the Type of Access.

9. Click OK until you complete the access permissions.

Now, when the NPM’s browser view is accessed, only those users in the specified group, such as NPM Admins, can set and use the Capture screen features.
