Figure 14. VLAN page

VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical net- works. 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.

With 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.

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 every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.

You can select from two types of VLAN: 802.1Q Tag-Based VLAN and Port-Based VLAN. The VLAN Setup screen changes depending on whether you choose 802.1Q Tag-Based VLAN type or Port Based VLAN type. The IEEE 802.1Q defines the operation of VLAN bridges that permit the definition, operation, and adminis- tration of VLAN topologies within a bridged LAN infrastructure.

Figure 15 on page 42 shows a diagram of possible VLAN connections.
