[0012] Among the various loopbacks of communication equipment, the external loopback of the device port is a very important loopback. It can directly determine whether the cause of the abnormal network connection is the failure of the communication equipment itself or the failure of the network terminal (such as the network card on the user computer). Fault. The present invention will be further described in detail below by taking a network switch as an example in conjunction with the accompanying drawings.
[0013] figure 2 It is a schematic diagram of the remote control method for communication equipment of the present invention. As shown in the figure, when the present invention is implemented in practice, a loopback device is connected in series between the port outside of the switch and the user connection port, that is, a loopback channel is established outside the port of the switch For example, a loopback device is connected in series between the network port transfo...
