IPM FAQs
Q.
What workstation and network devices do I need to run IPM?
A.
IPM comprises several distinct pieces of functionality.
• The IPM server application runs on Solaris 2.8, Solaris 2.9, and Windows 2000 Server and
Windows 2000 Professional.
• The IPM client application, including the user interface, runs on Solaris 2.8, Solaris 2.9,
Windows 2000 Professional and Server (with SP3 and SP4), Windows 2000 Advanced Server
(with SP3, SP4), Windows XP Pro (SP1a) or Windows 2000 (WS2K3). For Solaris and
Windows, the IPM client can run on the same system as the IPM server, or on a different system.
• We strongly recommend version 12.1 or later of the Cisco IOS software.
• The IPM application requires a software agent embedded in the Cisco IOS software, called the
SA Agent to source network performance measurements. At least one router running a Cisco
IOS software release that supports SA Agent is required.
• If you are using IPM to monitor SNA latency, you must install the NSPECHO mainframe
application on your MVS system. NSPECHO is distributed with the IPM software.
• IPM provides access to historical reporting information via a Web browser. To view this
information, you need a Web browser, such as Netscape Navigator or Microsoft Internet
Explorer, on your workstation.
Q.
I want to run the IPM client as an applet from a Web browser. How can I find out if I already have
the Java plug-in?
A.
From the IPM Main Window, select View > CiscoWorks Home Page. When the CisoWorks
homepage displays, click Client > Web Client.
• If you already have the Java plug-in, the Java applet loads and the Web client launches.
• If you do not have the Java plug-in, the IPM Client Main Window displays the prompt, Click
here to get the plug-in. Click the prompt and continue with the plug-in installation procedure,
as described in the “Installing IPM on Windows” chapter of the Installation Guide for
Internetwork Performance Monitor.
Q.
Why does my IPM client hang when I’m trying to run it as an applet on Solaris?
A.
There may be a problem with the CLASSPATH environment variable.
CLASSPATH specifies the path to the Java class library on your system. However, if CLASSPATH
is set in the environment from which you launch the Web browser, the Java plug-in cannot function
properly, and you cannot run the IPM client as an applet.
To prevent this problem, use the following procedure to make sure CLASSPATH is not set in the
environment from which you launch the Web browser:
Step 1 On the command line, enter the env command.
A list of environment settings appears.
Step 2 Find CLASSPATH in the list.
Step 3 If CLASSPATH is not set to null (no characters), set it to null.
For csh or tcsh, enter:
setenv CLASSPATH
For ksh, enter:
export CLASSPATH=
