VLAN or virtual LAN refers to the part of a computer that is found in one of the layers. It is also known as the local area network. It is located in the data link layer, which is the OSI layer 2 of the computer network. This has many vital uses on the computer. It provides security in your computer as well as conducting traffic in your computer and computer system.
The native VLAN should be used on the trunk if Cisco best practices are being implemented. A small business uses VLANs 2, 3, 4 and five between two switches that have a trunk link between them. In this case, the native VLAN that should be used on the trunk is 6.
