Setting Up a Protocol Analyzer on Your Network
Maintaining Your Software

pmp-0049 (September 2012)
Example of a protocol analyzer setup for an SM
The following is an example of a network protocol analyzer setup using Wireshark 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, and subscriber PC are successfully connected.
Wireshark 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 is the hub insertion point.
Procedure 11 Setting up a protocol analyzer
1
Verify that you have connectivity from the laptop computer to the SM
2
Launch the protocol analyzer software on the laptop computer
3
In the Capture menu, select Interfaces.
4
In the resulting dialog window, click the Start button corresponding to the Ethernet card connected
to the SM
