A VLAN is a group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire.
A VLAN is a group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible. Meaning that even though your servers at Cherry Servers might be spread out through multiple network devices, to you it will appear as if they are directly connected to one another.
VLANs define broadcast domains in a Layer 2 network. A broadcast domain is the set of all devices that will exchange network packets between one another. VLAN network packets at Cherry Servers are not layer 3 routed, meaning that network packet exchange is only possible between domain members in a VLAN setting. Traffic will not be filtered or limited between devices in a VLAN. In summary with a VLAN you get private and unfiltered traffic between your servers that operates within Layer 2 broadcast domain.
