Unit 3 Assignment 1 VLAN

• You can logically create a new network with additional permissions for your leaders (MANAGEMENT network) by adding another VLAN.
• Employees can sit anywhere to access the resources in their departments, provided that you allow them to do so.
• Computers in the same department can communicate with each other although they are at different floors.
If these departments expand in the future you can still use the same network in any other shop. For example, SHOPS needs to have 50 more employees, a router is needed to enable different VLANs to communicate with each other. Without a router, the computers within each VLAN can communicate with each other but not with any other computers in another VLAN. For example, we need a router to transfer file from MANAGEMENT to TECH. This is called “interVLAN routing”.
When using VLANs in networks that have multiple interconnected switches, you need to use VLAN trunking between the switches.
With VLAN trunking, the switches tag each frame sent between switches so that the receiving switch knows which VLAN the frame belongs to. This tag is known as a VLAN ID. A VLAN ID is a number which is used to identify a VLAN.
Note: Trunk link does not belong to a specific VLAN, rather it is a conduit for VLANs between switches and routers. To allow interVLAN routing you need to configure trucking on the link between router and
switch.
