The unmanaged switch belongs to the data link layer device. It can identify the MAC address information in the data packet, and then forward it according to the MAC address, and record these MAC addresses and corresponding ports in an internal address table of its own.
The specific workflow is as follows:
(1) When the switch receives a data packet from a port, it first reads the source MAC address in the packet header, so that it knows which port the machine with the source MAC address is connected to;
(2) Go to read the destination MAC address in the header, and look up the corresponding port in the address table;
(3) If there is a port corresponding to the destination MAC address in the table, copy the data packet directly to this port;
(4) If the corresponding port cannot be found in the table, the data packet will be broadcast to all ports. When the destination machine responds to the source machine, the switch can learn which port the destination MAC address corresponds to, and it will not be the next time the data is transmitted. You need to broadcast to all ports again.
