Chapter 3 Using IPM to Measure Network Performance

Measuring Network Performance for SNA

You can customize both the request and response payload sizes to model traffic flow for various applications. The SNA operations also measure availability and errors for SNA services.

To measure end-to-end performance for SNA:

Step 1 Define a device as the source device from which to measure performance. For details on defining a source device, see the Defining a Source Device.

Step 2 Define a device as the target of SNA echo requests from the source device. For details on defining a target, see the Defining a Target.

To control how statistics are collected, use one of the default SNA operations, or define your own SNA Echo operation. For details on defining an SNA Echo operation, see the Defining an SNA Echo Operation.

Step 3 Define a collector to measure performance between the source router and target you defined. For details on defining a collector, see the Defining a Collector. If you set the collector’s schedule to On Demand, start the collector when desired.

Step 4 View the statistics in the Echo Historical Statistics window. For details on viewing end-to-end statistics for SNA, see the Viewing Statistics for SNA.

Defining an SNA Echo Operation

The SNA Echo Operation Configuration window allows you to create, modify, or delete an SNA Echo operation.

To define an SNA Echo operation:

Step 1 From the IPM Main Window, select Edit > Configuration.

The Configuration window appears.

Step 2 Click Operation.

The Operation Configuration window appears within the Configuration window.

Step 3 Click Echo.

The Echo Operation Configuration window (Figure 3-11) appears.

Step 4 In the Name field, enter a descriptive name to assign to the operation. In the Description field, you can enter a brief description of the operation, including its purpose.

Step 5 In the Protocol field, select one of the following protocols:

•SNA LU 0

•SNA LU 2

•SNA SSCP

Step 6 In the Request Payload field, enter the number of bytes to use for the size of the payload of the request packet. The default setting is 64 bytes.
