  • Page 27: Chapter 2: Network Planning

    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. The switch have, therefore, been recognized as one of the most important building blocks for today’s networking technology.

  • Page 28: Application Examples

    Network Planning Application Examples The Gigabit Ethernet Switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections and linking VLANs or IP subnets. Some typical applications are described below. Collapsed Backbone The Gigabit Ethernet Switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in...

  • Page 29: Network Aggregation Plan

    Application Examples Network Aggregation Plan With 24 parallel bridging ports (i.e., 24 distinct collision domains), a Gigabit switch stack 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 in a stack of 24-port Gigabit Ethernet switches are providing 1000 Mbps connectivity through stackable switches.

  • Page 30: Remote Connections With Fiber Cable

    Network Planning 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-LH link up to 70 km. This allows a switch stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

  • Page 31: Making Vlan Connections

    Application Examples Making VLAN Connections The 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 secure and cleaner network environment.

  • Page 32: Using Layer 3 Routing

    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 Switch is routing switch that provide 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.

  • Page 33: Application Notes

    Application Notes Application Notes 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. For network applications that require routing between dissimilar network types, you can attach these switches directly to a multi-protocol router.

  • Page 41: Connecting Switches In A Stack

    Connecting Switches in a Stack Connecting Switches in a Stack Figure 3-7 shows how the stack cables are connected between switches in a stack. Each stacking connection is a 48 Gbps full-duplex high-speed serial link using proprietary stacking cables. The switch supports a line- and ring-topology stacking configuration, or can be used stand alone.

  • Page 42: Stacking Topologies

    Installing the Switch Select the Master unit in the stack by pressing the Master button in on only one of the switches. Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the system will select the unit with the lowest MAC address as the Master.
