[. . . ] VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs 2-3 NETWORK PLANNING can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the inter-switch links. This switch also has a Private VLAN feature. This allows modification of the default VLAN to provide port-based security and isolation between ports within the VLAN. Data traffic on these ports can only be forwarded to, and from, the uplink port. Private VLANs and normal VLANs can exist simultaneously within the same switch. In the figure below, ports 1-5 are connected to four end users and a server in a normal VLAN configuration. The remaining ports are configured into a private VLAN.

Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. To interconnect distinct VLANs or IP subnets, you can attach the switch to a standard Layer 3 router. For network applications that require routing between dissimilar network types, you can attach the switch directly to a router. As a general rule the length of fiber optic cable for a single switched link should not exceed: · · · 1000BASE-SX: 550 m (1805 ft) for multimode fiber. 1000BASE-LX: 5 km (3. 2 miles) for single-mode fiber. 1000BASE-ZX: 70 km (43 miles) for single-mode fiber. However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-5 NETWORK PLANNING 2-6 CHAPTER 3 INSTALLING THE SWITCH Preparing the Site for VDSL/POTS Connections In multi-tenant buildings, phone lines from the service provider enter the site and are terminated at a location referred to as the MPOE (Minimum Point of Entry). The MPOE is the "demarcation" point where the service provider's cables end and that of the building's owner/customer begins. An MPOE typically consists of two sets of punch-down blocks; one from the service provider, and the other from the customer. The customer's punch-down blocks are connected to PBX or MDF equipment in the building. A PBX may have either analog or digital cards that provide the phone lines to individual end users. The PBX lines are usually connected to the end users through another set of punch-down blocks or patch panels. The following figure displays the normal wiring before installing the VDSL switch.
