Explanation:

In the current Huawei environment, using physical servers increases IT resource management difficulties, wastes resources, and reduces security. Therefore, exporting VM raw disks and importing images to Huawei Cloud are adopted to migrate to Huawei cloud. In this operating environment, many serial debugging devices cannot be directly debugging, and the serial port server is the best way to perform serial port to TCP.

A serial port server can be regarded as a dedicated linux device. It is used to extend the serial port, convert it into a network (telnet service), and connect debugging devices such as the Console port of the switch, boards, nes, and loopback boxes. Serial port server models are NC616 and NC632.
