Finisar Surveyor manual Transmit Specifications

Chapter 8

Transmit Specification

Packet Blaster plug-in allows you to generate packets and send them onto a net- work. This can be used to force the network to respond to known or suspected prob- lem conditions or loads. Transmitted data can answer “What If?” questions about the network or particular network resources.

To transmit data, you first set up a Transmit Specification. After the Transmit Specification is loaded to a module, click on the Start button to begin transmit. You can also transmit a previously-captured data file (capture file).

You can transmit the contents of a capture file. Data previously collected in the capture file can be loaded to a module and sent to the network.

Using THGm, you can transmit packets at full network speed or faster. This allows you to set up high traffic conditions and see how the network performs. Surveyor can also transmit a variety of user-defined packet contents to see their effect on the network.

With multiple modules, transmitted data can be captured by another analyzer card. You can use the capture and view features in the Surveyor software to analyze the results, all from the same PC.

Although you can transmit using Portable Surveyor 10/100 Ethernet Analyzer Card or NDIS modules, these devices are not always accurate transmit devices. The actual rate of transmission for these devices is not predictable.

Transmit Specifications

An example Transmit Specification dialog box is shown in Figure 8-1 on page 8-2. For additional views of this dialog box, see the Transmit Specification examples at the end of this chapter. To bring up the Transmit Specification dialog box, press the

button from the Detail View toolbar.
