(VLAN is a switching network that is logically differentiated according to different functions, different project groups or different uses, and does not distinguish the physical orientation of these users. VLAN has properties similar to physical LAN. Using VLAN can distinguish terminals that are not in the same physical LAN into a VLAN group. A VLAN can have multiple ports, and all unicast, multicast, and broadcast data packets can only be forwarded and distributed in the same VLAN.
