1-1 Chapter 1: Introduction Overview The TigerSwitch 10/100/1000, SMC8126L2, is an intelligent Layer 2 switch with 26 10/100/1000BASE-T ports, four of which are combination ports * that are shared with four SFP transceiver slots (see Figure 1-1, Ports 21-24). The SMC8126L2 includes an SNMP-based man...

Introduction 1-2 1 Switch Architecture The SMC8126L2 employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. It also features full-duplex capability on all ports, which effectively doubles the bandwidth of e...

Description of Hardware 1-3 1 Description of Hardware 10/100/1000BASE-T Ports The SMC8126L2 contains 26 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports on this switch support automatic MDI/MDI-X operation, you can use straight-thr...

2-1 Chapter 2: Network Planning Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. These switches have, therefore, been recognized as one of t...

2-2 Network Planning 2 Application Examples The SMC8126L2 is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. Collapsed Backbone The SMC8126L2 is an excellent choice for mixed Ethe...

2-3 Application Examples 2 Network Aggregation Plan With 26 parallel bridging ports (i.e., 26 distinct collision domains), a switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100/1000BASE-T ports ...

2-4 Network Planning 2 Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to 100 km. This allows a switch ...

2-5 Application Examples 2 Making VLAN Connections This switch support VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more ...

2-6 Network Planning 2 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. 2. For network applications th...
