Before understanding the VLAN isolation function of the switch, we first understand the Ethernet switch: Ethernet switch is a switch based on Ethernet data transmission. Each port of the Ethernet switch can be connected to the host, generally working in full-duplex mode, and can be connected to the opposite port at the same time, so that each pair of devices communicating with each other can communicate without interfering with each other.
VLAN refers to the virtual local area network, is a group of logical equipment and users, the communication between this group of equipment and users is similar in the same network segment, can be different locations, different networks, different users together to form a virtual network environment, just like the use of local LAN as convenient, flexible, effective. VLAN can reduce the management cost of moving or changing the location of workstations, especially for some companies with frequent changes in business conditions, this part of the management cost is greatly reduced
Vlan isolation is actually based on the role of Vlan technology, through the Vlan division of different ports, equipment terminals, users to achieve complete isolation of business data. In addition, Vlan isolation can be based on the port of the switch Vlan partition for networking isolation, also can be based on IP Vlan partition for networking isolation Ethernet switch under VLAN technology, you can build multiple LAN, in real life, want to build a different LAN for each port, For example, the R&D department, business department, operation department, etc., of the same company
Thank you for reviewing the introduction of VLAN isolation function of Ethernet switch brought by Shenzhen Haidiwei Optoelectronic Technology Co., LTD., Our switch product series, also covers a number of specifications of the switch, such as: all optical port switch, 8 port switch, 100 MEGABit switch, network management switch and so on, welcome to visit.
