30.4 EXAMPLE OF A PROTOCOL ANALYZER SETUP FOR AN SM
The following is an example of a protocol analyzer setup using Ethereal software to
capture traffic at the SM level. This example is based on the following assumptions:
◦ All required physical cabling has been completed.
◦ The hub, protocol analyzer laptop computer, subscriber PC are successfully
connected.
◦ The SM is connected
− as shown in Figure 135 on Page 363.
− to the subscriber PC and the AP.
◦ Ethereal software is operational on the laptop computer.
Although these procedures involve the SM, the only difference in the procedure for
analyzing traffic on an AP or BH is the hub insertion point.
An IP configuration screen of the example SM is shown in Figure 137.
