As we all know, the Internet has been perfectly integrated with our life, so we can't leave the switch now, without it we can't use many of the features on the Internet. As long as there is a switch, any two network nodes can exchange information. It is with the switch that we have such a rich Internet life.
A switch, as its name suggests, refers to a switch that provides shared services to any two network nodes that access the switch.
The exchange is based on the need to transmit information at both ends of the communication, and the method of using manual equipment to transmit the information to be transmitted to the corresponding route. This is the concept of the switch.
Today, switches are more oriented to application requirements, and the extensive use of broadband has greatly increased the demand for switches.

There are three base modes on the switch, namely user mode, privileged mode, and global mode. When we first enter the switch, we are in user mode. In user mode, we can query the switch configuration and some simple test commands. For a default unconfigured switch, we must set some naming, password and remote connection. For better maintenance.
