Exporting All the Diagnostic Files
Yealink phones support three types of diagnostic files (including Pcap trace, log files, and BIN configuration files) to
help analyze your problem. You can export these files at a time and troubleshoot if necessary. The file format of the
exported diagnostic file is *.tar.
Procedure:
1. From the web user interface, navigate to Settings > Configuration.
2. Click Start in the Export All Diagnostic Files field to begin capturing signal traffic.
The system log level will be automatically set to 6.
3.
Reproduce the issue.
4. Click Stop in the Export All Diagnostic Files field to stop the capture.
The system log level will be reset to 3.
5. Click Export to open the file download window, and then save the diagnostic file to your local system.
A diagnostic file named <MAC>-DiagnoseInfo.tar is successfully exported to your local system.
Note: After exporting the diagnostic files, you can create a ticket to describe your problem at ticket.yealink.com, and Yealink
support team will help you locate the root cause.
Log Files
You can configure your device to generate the log files locally, upload the log to the USB flash drive connected to
the phone or sent the log to a syslog server in real time, and use these log files to generate informational, analytic
