Troubleshooting
This chapter provides an administrator with general information for troubleshooting some
common problems that he (or she) may encounter while using the VC110 video conferencing
endpoint.
Troubleshooting Methods
The endpoint can provide feedback in a variety of forms, such as log files, packets, status
indicators and so on, which can help an administrator to find the endpoint problem more easily
and resolve it.
The following sections will help you to better understand and resolve the working status of the
endpoint.
 Viewing Log Files
 Capturing Packets
 Getting Information from Status Indicators
 Analyzing Configuration Files

Viewing Log Files
The log files are Yealink specific debug files which may be requested by the Yealink support
organization if you need technical support. The current log files are time stamped event log files.
You can export the log files to a syslog server or the local endpoint. The administrator can
specify the location where the log will be exported to and the severity level of the log.
Endpoint Log Level specifies the log level to be recorded. The default endpoint log level is 6.
Endpoint log level parameters are described below:
