The project is the basis of the following theory:
VLAN is a logical network, provides logical segmentation of network. Virtual LANs separate layer2 switch into multiple-broadcast domains. Each VLAN is its own individual broadcast domain, i.e. IP subnet. Here groups of ports or individual ports can be assigned to a specific VLAN and Only the ports which are belonging to the same VLAN can freely communicate; ports assigned to separate VLANs require a router to communicate, Broadcasts from one VLAN will never be sent ports belonging to another VLAN. A layer two switch that supports VLAN is not always necessarily a layer three switch, in addition to supporting VLANs, must also be capable of routing, and caching IP traffic flows. Layer 3 switches allows IP packets to be switched as opposed to routed, which reduces latency. VLANS work by handling tags to the network packets creating the functionality and aspect of network traffic, which is physically on one and only one network but acts as …show more content…
Job of the router is to filter broadcast traffic. Advantages of VLAN can be, broadcast control or security, flexibility and scalability. By logically, vlans increase inclusive network performance by logically, grouping resources and users together. VLANs make sure of that a particular set of users are logically grouped in any case of the physical location. VLANs can heighten scalability security and network management and clarify the tasks when additions, changes and moves to network. Configuration or reconfiguration of VLAN is done through the software. When configuring vlans, physically connecting or moving equipment and cables are necessary. The network is logically segmented into all different broadcast domains through vlans. Packets can be only switched between the ports that are designated for the same VLAN. Workstation in a VLAN category is restricted to communicating with other devices or file servers in the same VLAN
