New Features

IPM Release 2.4 implements the following new features:

Support to change the IPM Database password and to enable the IPM Administrative password at the time of installation.

It is strongly recommended that you enable the IPM Administrative password at the time of IPM 2.4 installation for securing the IPM configuration.

Improved startup time of the IPM processes compared to the earlier release of IPM. Now the IPM processes are fine-tuned to start instantly.

Support for a new IPM Collector status—Operation Pending State has been added for the IPM collector in the IPM Main Window. This state shows that IPM is in the process of configuring collectors.

Support to add a source or target using IP Address and Host Name. In the IPM  2.4 release, you do not have to make the devices Reverse Address Resolvable.

Support for terminal server on Windows 2000 platform.

Support to launch the IPM Online Help through CiscoWorks2000 desktop.

Support for IPM server on Solaris 2.8.

Support for Web browser based IPM client in Netscape Navigator 4.76 on Solaris platform, and for Netscape Navigator 4.77, 4.78, and 4.79, Internet Explorer 5.5, with Service Pack 2 and Internet Explorer 6.0 on Windows platform.

Caveats for Using IPM

This section lists all the caveats for using IPM.

Uninstalling IPM and CiscoWorks2000 CD One

When you have both IPM and CiscoWorks2000 CD One on your system, always run the command ipm cw2ksetup uninstall before uninstalling CiscoWorks2000 CD One. Uninstallation will not be clean if CiscoWorks2000 CD One is uninstalled without running this command.

Six Minute Delay while Downloading Console on Windows 2000

On some Windows 2000 systems, the initial download of large Java applets (or subsequent downloads of the same applets that are not cached locally) might take longer than expected (up to 6 minutes in some instances).

After the applet has been loaded and cached locally, this problem no longer occurs. The delay is caused by client side filtering mechanisms such as virus scanning. Some virus scanners are configured to automatically scan content downloaded by browsers. Scanning consumes a lot of memory and results in disk paging on most systems. Downloading is significantly slower than expected, because of this. (The effect is less on systems with large amounts of RAM and virtual memory.)

Workaround:

Disable the automatic scanning of all downloaded files, and instead, enable the scanning of program files only (specified by file extension). Exact instructions vary depending on the virus scanner installed on your system.

For more information, see the following article:

[Bug ID: CSCdt22462]

Exception will be Displayed when Moving from IPM Server Homepage to CiscoWorks2000 Desktop

This is observed only when IPM 2.4 runs on Solaris platform. When IPM Server Homepage is launched from IPM non-web client and then if you launch CiscoWorks2000 desktop by changing the port number to 1741 from 1744 in the browser navigation bar, IPM displays the Java Exception message.

You can disregard this exception message.

[Bug ID: CSCin00904]

Using Shortcut Keys on Internet Explorer Web Clients

To use the IPM menu shortcut keys, you should first activate the IPM Main Menu by clicking on any of the menu options using the mouse.

To use the IPM menu shortcut keys consecutively, activate the IPM Main Window by clicking anywhere within the IPM Main Window (gray box) using the mouse, every time you use the IPM shortcut keys.

[Bug ID: CSCin07293]

Table 1 describes the problems known to exist in this release.

Table 1 IPM 2.4 Known Problems 

Bug ID
(Severity)
Summary
Explanation

CSCdr78845 (3)

Intermediate hops are added to the target list.

Whenever a path-hop (path-echo) analysis is done, IPM adds each hop IP address to the target list. Each hop IP address then becomes a new target.

Workaround:

None.

CSCds33719 (3)

Update of CD One fails due to locked perl.dll.

This is observed only on Windows platform.

If IPM is installed on a machine that has the RWAN bundle, re-installation/installation of CD One/CiscoWorks2000 applications may fail because of a shared library being locked.

This problem also occurs when CiscoWorks2000 and IPM installations exist on the same machine and you install or upgrade other CiscoWorks2000 components.

Workaround:

1. Run ipm stop.

2. Run ipm cw2ksetup uninstall.

3. Re-install/install CD One/CiscoWorks2000 application.

4. Run ipm cw2ksetup install.

5. Run ipm start.

The first two steps remove IPM's dependency on the shared library and the last two steps integrate IPM with CiscoWorks2000.

CSCdw21042 (3)

IPM Client cannot add source routers with long SNMP RW community.

IPM client will not add routers as a source or target if the read and write community string is longer than 32 characters.

Workaround:

Enter the read and write community string of length ranging from 1 to 32 characters.

CSCin05269 (3)

Client connection lost.

Sometimes the IPM client may lose connection with Data Collection server, Data View server, RTP (Real-Time Poller) server, or Configuration server.

One of the displayed error messages is:

Client unregistration with the Data Collection Server Failed

Workaround:

IPM client automatically connects to the server after you perform any operations with IPM client. If the problem persist, restart the browser or non-web client.

CSCdr84612 (4)

Business days calculations do not include timezone of source and target.

The business day setting is applied only to the IPM server's location. This setting does not take into account, the business day at source and target.

Workaround:

None.

CSCds65863 (4)

While the Java applet loads, web server warnings appear.

While the IPM server is running, the web server error log shows a few periodic warnings.

Workaround:

Ignore these warnings. The web server log file is cleared automatically when it reaches 200K.

CSCin03525 (4)

Uninstallation of CD One includes IPM2.4 as one of the component.

At the time of uninstallation of CiscoWorks2000, disregard the message that indicates Internetwork Performance Monitor  2.4 will be uninstalled with the other CiscoWorks2000 application.

IPM will not be uninstalled as part of CiscoWorks2000 uninstallation.

Workaround:

None.

CSCin08941 (4)

Integration problem with CD One when Secure Sockets Layer (SSL) is enabled.

This is observed in IPM 2.4 release. The following actions result in a problem:

1. Install CD One.

2. Install IPM.

3. Un-integrate IPM with CD One.

4. Enable SSL on CD One.

5. Re-integrate IPM with CD One using the command ipm cw2ksetup install.

CSCin08941 (4)

(Continued)

Integration problem with CD One when SSL is enabled.

(Continued)

When you launch the secure Web client, the following error message appears:

On Windows:

Unauthorized Access - Not Logged in

On Solaris:

The Daemon Manager does not start and the message is displayed:

Integrating server with CiscoWorks2000 Common Management Foundation. Daemon Management stopping. This may take a few minutes. Stopping unterminated processes. Found Non-SSL compliant Applications. Please disable SSL and then start the Daemon Manager

Workaround:

Follow either of these procedures:

Procedure 1

1. Run ipm cw2ksetup uninstall to remove IPM integration with CD One.

2. Start the CD One Daemon manager.

3. Disable SSL.

4. Run ipm cw2ksetup install

Procedure 2

1. Install CD One on a different server without enabling SSL.

2. Install IPM.
