Chapter 2 Getting Started With IPM
Running Simultaneous IPM Sessions
Running Simultaneous IPM Sessions
IPM allows you to run multiple sessions of the IPM client simultaneously. Central services and database
functions are provided on an IPM server that communicates to multiple IPM clients. You can install the
IPM client software on the same system as the IPM server, or on a different system on the same network
as the IPM server.
Running more than one IPM client on the same workstation can degrade the workstation’s performance.
Configuring the IPM Components
To collect network performance metrics using IPM, you must define a collector in a source router. A
collector is a definition of a source router, a target device, an operation, and a collector schedule.
To define a collector, complete the following tasks:
• Defining a Source Device
• Defining a Target
• Defining a Collector
Defining a Source Device
IPM source devices are the devices from which packets are sent to measure and store statistical data,
including network latency, jitter, availability, packet loss, and errors. Each source device must contain
the Cisco IOS software SA Agent feature.
The types of operations you can use are determined by the version of the Cisco IOS software running on
the source device. IPM automatically checks the Cisco IOS software version on the device and limits the
creation of operations to those supported by the source device.
For information about the recommended versions of Cisco IOS software to use with IPM, see the “Cisco
IOS Software Requirements” section of the Installation Guide for Internetwork Performance Monitor.
To define a new source router:
Step 1 Verify that the SNMP read community and write community strings are configured properly on the
router.
If you want to receive traps at your network management system (NMS), verify that the router is
configured to send SA Agent-generated traps to your NMS.
For information about trap configuration on the source router, see the “Configuring Your Routers to Send
SA Agent-Related Traps” section in the “Preparing to Install” chapter of the Installation Guide for
Internetwork Performance Monitor.
Step 2 From the IPM Main Window (Figure 2-2), select Edit > Configuration.
The Configuration window (Figure 2-3) appears. By default, Sources is selected in the navigation pane
and the Source Configuration window appears within the Configuration window.
