  • the topology of the network can be learned by dividing the source address of the number of frames from all connected networks. For example, when the switch receives the data frame from host A from port 1, it can reach the continuous learning process through the host through port 1, and the switch establishes a forwarding.
  • An example of such a forwarding table is shown in Table 2 below. Shown as follows:
  • the switch When the switch receives a data frame from one of the ports, it looks up the forwarding table according to the address of the data frame, such as the correspondence between the address existing in the forwarding table and a port of another network device such as a bridge or a switch.

The switch connected to Host B also needs to know the information (MAC address) of the switch to which Host A is connected.
