Saving diagnostic logs to the diagnostic log file
By default, the device saves diagnostic logs from the diagnostic log file buffer to the diagnostic log file every 24 hours. You can adjust the saving interval or manually save diagnostic logs to the diagnostic log file. After saving diagnostic logs to the diagnostic log file, the system clears the diagnostic log file buffer.
The device supports only one diagnostic log file. The diagnostic log file has a maximum capacity. When the capacity is reached, the system replaces the oldest diagnostic logs with new logs.
