How to switch 10GE upstream transmission to GE upstream transmission of the upstream port on the Huawei MA5800 X15?

On the Huawei MA5800 X15, both the control board and the upstream board can be used for 10GE/GE upstream transmission. By default, the device uses 10GE for upstream transmission. You can set the upstream port by running speedcommand. To avoid communication failures, the rate of the upstream port must be the same as that of the port on the interconnected device.
