Figure 15.16 shows the same switched LAN divided into VLANs. The whole Idea of VLAN techology is to divide a LAN into logical, instead of physical, segment. A LAN can be divided into several logical LANs called VLANs. Each VLAN is a work group in the organization. If a person moves from one group to another, there is no need to change the physical configuration. The group membership in VLANs is definited by software, not hardware. Any station can be logically moved to another VLAN.All members belonging to a VLAN can receive broadcast messages sent to that particular VLAN.
