  • Page 107: Virtual Local Area Networks (Vlans)

    Virtual Local Area Networks (VLANs) A Local Area Network (LAN) can generally be defined as a broadcast domain. Hubs, bridges or switches in the same physical segment or segments connect all end node devices. End nodes can communicate with each other without the need for a router. Routers connect LANs together, routing the traffic to the appropriate port.

    VLAN membership properties. A ‘U’ for a given port means that packets leaving the switch from that port are Untagged. Inversely, a ‘T’ for a given port means that packets leaving the switch from that port are tagged with the VLAN ID associated with the port.

    4. The following situations produce results as described: • If an untagged packet enters Port 1, the switch tags it with a VLAN tag value 10. The packet has access to Port 2 and Port 3. The outgoing packet is stripped of its tag to leaves Port 2 as an untagged packet.

  • Page 111: Appendix C Network Cabling

    This appendix provides specifications for cables used with a NETGEAR GS108T Gigabit Smart Switch. Fast Ethernet Cable Guidelines Fast Ethernet uses UTP cable, as specified in the IEEE 802.3u standard for 100BASE-TX.The specification requires Category 5 UTP cable consisting of either two-pair or four-pair twisted, insulated copper conductors bound in a single plastic sheath.

    The crossover function is usually implemented internally as part of the circuitry in the device. Computers and workstation adapter cards are usually media-dependent interface ports, called MDI or uplink ports. Most repeaters and switch ports are configured as media-dependent interfaces with built-in crossover ports, called MDI-X or normal ports. Auto Uplink technology automatically senses which connection, MDI or MDI-X, is needed and makes the right connection.

    To wire patch panels, you need two Category 5 UTP cables with an RJ-45 plug at each end, as shown in Figure C-3. Network Cabling GS108T Smart Switch Software Administration Manual v1.0, May 2007...

However, using telephone cable results in excessive collisions, causing the attached port to be partitioned or disconnected from the network.

    “returned” to the sender end. The factors that affect NEXT and cross talk are exactly the same as outlined in the Return Loss section. The cross-talk performance is directly related to the quality of the cable installation. Network Cabling GS108T Smart Switch Software Administration Manual v1.0, May 2007...

    GS108T Smart Switch Software Administration Manual Patch Cables When installing your equipment, replace old patch panel cables that do not meet Category 5e specifications. As pointed out in the NEXT section, this near end piece of cable is critical for successful operation.
  • Page 117 11801:1995 Category 5 specifications. Install Category 5e cable where possible, including patch panel cables. Minimize transition points, jacket removal, and untwisted lengths.
