Hello,
When a device is working, the system records the operating status of the device in real time and generates certain information. If the UDP port number, information recording device, and information severity are specified for a Syslog server of a specified IP address, information is sent to the Syslog for query. This allows the network administrator to monitor the device operation and diagnose network faults.
