[. . . ] This allows you to assign multiple VLAN groups to the "trunk" ports (that is, tagged ports) connecting different switches.

Making VLAN Connections Note: When connecting to a switch that does not support IEEE 802. 1Q VLAN tags, use untagged ports. 2-5 NETWORK PLANNING Using Layer 3 Routing VLANs can significantly enhance network performance and security. However, if you use conventional routers to interconnect VLANs, you can lose most of your performance advantage. The TigerSwitch 10/100 provides wire-speed routing, which allows you to eliminate your conventional IP routers, except for a router to handle non-IP protocols and a gateway router linked to the WAN. Just assign an IP address to any VLANs that need to communicate. The switch will continue to segregate Layer 2 traffic based on VLANs, but will now provide inter-VLAN connections for IP applications. This switch will perform IP routing for specified VLAN groups, a directly connected subnetwork, a remote IP subnetwork or host address, a subnetwork broadcast address, a switch IP address on a specific IP subnetwork, or an IP multicast address.

IP Routing for Unicast Traffic 2-6 CONNECTIVITY RULES Connectivity Rules When adding hubs (repeaters) to your network, please follow the standard connectivity rules for Ethernet or Fast Ethernet. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices. 1000 Mbps Gigabit Ethernet Collision Domain Maximum Fiber Optic Cable Distance for 1000BASE-SX Fiber Size 62. 5/125 micron 50/125 micron Fiber Bandwidth 160 MHz/km 200 MHz/km 400 MHz/km 500 MHz/km Maximum Cable Length 2-220 m (7-722 ft) 2-275 m (7-902 ft) 2-500 m (7-1641 ft) 2-550 m (7-1805 ft) Maximum Fiber Optic Cable Distance for 1000BASE-LX Fiber Size 9/125 micron Fiber Bandwidth N/A Maximum Cable Length 2 m - 10 km (7 - 32808 ft) Maximum Cable Distance for 1000BASE-T Type Cat. 5, 5e, or 6 100-ohm UTP Connector RJ-45 Maximum Cable Length 100 m (328 ft) Maximum 1000BASE-ZX Fiber Optic Cable Distance Fiber Diameter Fiber Bandwidth Cable Length Range 70* - 100 km (43. 5 - 62. 1 miles) 9/125 micron single-mode N/A fiber (SMF) * For link spans exceeding 70 km, you may need to use premium single mode fiber or dispersion shifted single mode fiber. 2-7 NETWORK PLANNING 10/100 Mbps Ethernet Collision Domain Maximum 10/100 Mbps Ethernet Cable Distance Type 10BASE-T Cable Type Twisted Pair, Category 3 or better Max.

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. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. For network applications that require routing between dissimilar network types, you can attach the TigerSwitch 10/100 units directly to a multi-protocol router. However, if you have to interconnect distinct VLANs or IP subnets, you can take advantage of the wire-speed Layer 3 routing provided by this switch. The multimode fiber modules are fitted with SC connectors, but you can attach an ST plug to the switch using an SC-to-ST plug converter. If you do use an ST plug converter, be sure you run cable from the Rx (Tx) port on the module to the Tx (Rx) port on the target device. As a general rule: · the length of Gigabit fiber optic cable for a single switched link should not exceed 550 m (1805 ft) for 1000BASE-SX multimode fiber or 5 km (16404 ft) for 1000BASE-LX single-mode fiber. the length of 100BASE-FX fiber optic cable for a single switched link should not exceed 2 km (1. 24 miles) for multimode fiber or 20 km (2. 43 miles) for single-mode fiber. · However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-9 NETWORK PLANNING 2-10 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerSwitch 10/100 units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. [. . . ] The successor IEEE 802. 3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable. Glossary-2 Fast Ethernet A 100 Mbps network communication system based on Ethernet and the CSMA/CD access method. Fast Ethernet Switch Device that provides a full 100 Mbps bandwidth (or either 10 or 100 Mbps bandwidth with Auto-Negotiation) to each port (LAN segment). Full Duplex Transmission method that allows switch and network card to transmit and receive concurrently, effectively doubling the bandwidth of that link.
