VLAN’s are a very useful tool in an enterprise network,they segment each departments data using a single switch and trunking.
Here we will discuss the basics of VLAN’s in a cisco internetwork.
A VLAN is a logically separate IP subnetwork. VLANs allow multiple IP networks and subnets to exist on the same switched network. The figure shows a network with three computers. For computers to communicate on the same VLAN, each must have an IP address and a subnet mask that is consistent for that VLAN. The switch has to be configured with the VLAN and each port in the VLAN must be assigned to the VLAN. A switch port with a singular VLAN configured on it is called an access port.
