9.1Introduction to VLAN

VLAN (Virtual Local Area Network) is a technology that divides the logical addresses of devices within the network to separate network segments based on functions, applications or management requirements. This way, virtual workgroups can be formed regardless of the physical location of the devices. IEEE 802.1Q protocol was announced to direct the standardized VLAN implementation. ES4710BD VLAN implementation follows IEEE 802.1Q.

VLAN technology can partition a big LAN into many separate broadcast domains dynamically to meet demands.

Each broadcast domain is a VLAN. VLANs have the same properties as the physical LANs, except VLAN are a logically partitioned rather than physical. Therefore, the partition of VLANs can be performed regardless of physical locations. Furthermore, broadcast, multicast and unicast traffic within a VLAN are separated from other VLANs.

With the afore-mentioned features, VLAN technology provides us with the following
