Network Diagnostics - Packet Capture

This page allows you to capture network communication on a port and then download the capture file for

troubleshooting. Choose one of the following capture options:

• Start/Stop - Define the start and stop criteria, and then click Start and Accept to begin the capture. When the

capture stops, the capture file is generated.

NOTE If a Start/Stop capture is running on any other port, the Get capture file button will be disabled until all

Start/Stop captures have completed.

○ Start capture: - When you check At (mm/dd/yyyy hh:mm AM/PM), enter the time and date, and click

Start, the packet capture begins at the date and time you specified.

NOTE The hours field is validated from 0 to 12, and minute field is validated from 0 to 59.

○ Continuous - Click Start and Accept to begin the capture. Click Save to momentarily stop the capture and

create the capture file. The capture will automatically resume. Click on the Start/Stop option to end the

Continuous capture.

○ If the port is set up for MS/TP, select an option in the Capture section.

To download the capture file

Capture files are Wireshark files that are added to the Device Log Archive .tgz file. Do the following to view the

files.

1 If you do not have Wireshark installed on your computer, download the latest version from the Wireshark

website (http://www.wireshark.org).

2 Run the install program, accepting all defaults. Include WinPcap in the installation.

3 On the i-Vu® Packet Capture page, click Get capture file to download the .tgz file. The message appears

"Retrieving the file, this may take a little while". Click OK.

NOTE If the size of the .tgz is large, there could be a considerable delay (for example, over 2 minutes) after

you click Get capture file until your browser begins the download.

4 Open the .tgz file. The files are in the captures folder.

Capture file names are based on the ports.

NOTE Clicking Get capture file generates the port's .pcap file. If the port has a .pcap file from a previous

capture, that file will be overwritten.

5 Extract the .pcap file from the .tgz file.

6 Open the .pcap file in Wireshark.
