IPM FAQs
CLASSPATH is set to null, and you can run the IPM client as an applet. Also make sure that you set the
environment variables NPX_PLUGIN_PATH and NPX_JRE_PATH to the correct values.
For example in ksh, enter:
export NPX_PLUGIN_PATH=/opt/NSCPcom/j2re1_3_1/plugin/sparc
export
NPX_JRE_PATH=/opt/NSCPcom/j2re1_3_1
For more detailed and current information on the environment variables to be set, refer the installation
instructions of Netscape.
Q.
How do I install the IPM client?
A.
You can install the IPM client either from the CD distributed with IPM, or by using a Web browser
to download the IPM client from an IPM server.
Q.
Do I have to install any software on the router to use SA Agent and IPM?
A.
The SA Agent is embedded in many but not all feature sets of the Cisco IOS software. A release of
the Cisco IOS software which supports SA Agent must be installed on the device IPM uses to source
network performance measurements.
The following table summarizes which Cisco IOS software releases support SA Agent and indicates
the maximum number of collectors.
Cisco IOS Release

1. We strongly recommend version 12.1 or later of the Cisco IOS software.

2. We recommend that you verify the SA Agent running on your Cisco IOS software. For
information about verifying whether SA Agent running on your Cisco IOS software, see “Verify
Your SA Agent Version” section on page C-2

3. The maximum number of collectors supported might be less than 200 or 500. This number is
dependent on several factors including the router configuration buffer size, the amount of DRAM
installed in the router, and the type of collectors configured in IPM.
