To capture packets using the Ethernet software:
Connect the Internet ports of the endpoint and the PC to the same HUB, and then use Sniffer,
Ethereal or Wireshark software to capture the signal traffic. You can also set mirror port on a
switch to monitor the port connected to the endpoint.
Getting Information from Status Indicators
In some instances, status indicators are helpful for finding endpoint troubles. Status indicators
may consist of the power LED, icons on the status bar of the display device or prompt messages.
The following shows two examples of obtaining the endpoint information from status indicators:

If a LINK failure of the endpoint is detected, the icon will appear on the status bar of
the display device, indicating the current network is not available.

If the power LED does not light, it indicates the endpoint is not powered on.
For more information on the icons, refer to Icon Instructions on page 33 .
Analyzing Configuration Files
Wrong configurations may have an impact on your endpoint use. You can export configuration
file to check the current configuration of the endpoint and troubleshoot if necessary. For more
information on how to export endpoint configuration, refer to
Importing/Exporting
Configuration on page 272 .
