Introduction to VLANs

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into

multiple logical networks. Devices on a logical network belong to one group. A device can

belong to more than one group. With VLAN, a device cannot directly talk to or hear from

devices that are not in the same group(s); the traffic must first go through a router.

In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security

among the subscribers. When properly configured, VLAN prevents one subscriber from

accessing the network resources of another on the same LAN, thus a user will not see the

printers and hard disks of another user in the same building.

VLAN also increases network performance by limiting broadcasts to a smaller and more

manageable logical broadcast domain. In traditional switched environments, all broadcast

packets go to each and every individual port. With VLAN, all broadcasts are confined to a

specific broadcast domain.

Note:

VLAN is unidirectional; it only governs outgoing traffic.

See

Chapter 6 on page 43

for information on port-based and 802.1Q tagged VLANs.
