31.4 EXAMPLEOFAPROTOCOLANALYZERSETUPFORANSM
The following is an example of a network protocol analyzer setup using Ethereal
®
software to capture traffic at the SM level. The Ethereal network protocol analyzer has
changed its name to Wireshark™, but functionality and use remains much the same. This
example is based on the following assumptions:
• All required physical cabling has been completed.
• The hub, protocol analyzer laptop computer, and subscriber PC are successfully
connected.
• The SM is connected
• as shown in
Figure 169 on Page 460.
• 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.
The IP Configuration screen of the example SM is shown in
Figure 171.
