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

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

Q.
Do I have to install any software on the router to use SA Agent and IPM?

the Cisco IOS software which supports SA Agent must be installed on the device IPM uses to source
network performance measurements.
