[. . . ] Port-based VLANs are suitable for small networks. A single switch can be easily configured to support several VLAN groups for various organizational entities (such as Finance and Marketing). When you expand port-based VLANs across several switches, you need to make a separate connection for each VLAN group. This approach is, however, inconsistent with the Spanning Tree Protocol, which can easily segregate ports that belong to the same VLAN. When VLANs cross separate switches, you need to use VLAN tagging. 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 Gigabit Ethernet Routing Switch 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.

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. 2-7 NETWORK PLANNING 1000 Mbps Gigabit Ethernet Collision Domain Maximum 1000BASE-T Gigabit Ethernet Cable Length Cable Type Category 5, 5e, or 6 100-ohm UTP or STP Maximum Cable Length 100 m (328 ft) Maximum 1000BASE-SX Gigabit Ethernet Cable Length Fiber Size 62. 5/125 micron multimode fiber 50/125 micron multimode fiber 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 1000BASE-LX Gigabit Ethernet Cable Length Fiber Size 9/125 micron single-mode fiber Fiber Bandwidth N/A Maximum Cable Length 10 km (7 - 16404 ft) Maximum 1000BASE-ZX Fiber Optic Cable Distance Fiber Diameter 9/125 micron single-mode fiber (SMF) Fiber Bandwidth N/A Cable Length Range 70* - 100 km (43. 5 - 62. 1 miles) 100 Mbps Fast Ethernet Collision Domain Type 100BASE-T X Maximum Fast Ethernet Cable Distance Cable Type Max. Cable Length Category 5 or better 100-ohm UTP 100 m (328 ft. ) or STP 2-8 APPLICATION NOTES Application Notes 1. 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 this switch directly to a router. 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 10km (16404 ft) for 1000BASE-LX 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 1000 units can be mounted in a standard 19-inch equipment rack or on a flat surface. [. . . ] Ethernet A network communication system developed and standardized by DEC, Intel, and Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. 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. Fast Ethernet A 100 Mbps network communication system based on Ethernet and the Glossary-2 CSMA/CD access method. Gigabit Ethernet A 1000 Mbps network communication system based on Ethernet and the CSMA/CD access method. [. . . ]
