CHAPTER 1

ABOUT THE

TIGERSWITCH 1000

Overview

The TigerSwitch 1000 is a high-performance Gigabit Ethernet switch designed for the network core. It provides eight 1000 Mbps ports that can significantly improve the performance of your network’s backbone, and deliver the throughput needed to support a broad range of advanced network applications.

With 16 Gigabits of aggregate bandwidth, the TigerSwitch 1000 can provide the quickest solution to meeting the growing demands on your networkís limited resources. This switch has six 1000BASE-SX SC fiber ports and two GBIC slots. Each 1000 Mbps port can support high-bandwidth connectivity within or between workgroups, and increased capacity for server farms, giving your users faster access to network-wide resources.

The TigerSwitch 1000 includes a built-in management agent that allows you to configure or monitor the switch using the embedded management program or SNMP/RMON applications. To manage the switch, you can make a direct connection to the console port on the switch’s front panel. You can also make a network connection to manage the switch using Telnet, the on-board Web agent, or any SNMP-based network management software.

ABOUT THE TIGERSWITCH 1000

Figure 1-1. Front and Rear Panels

Description of Hardware

1000BASE-SX Ports

These ports are SC-type fiber optic ports that operate at 1 Gbps full and half duplex. The ports can be connected to other IEEE 802.3z-compliant devices up to 550 m (1805 ft.) away using fiber optic cable. The switch is fitted with SC ports, but you can also attach an ST plug to the switch using SMC’s optional SC-ST Converter (Part Number: 99-012034-091).

GBIC Slots

The two slots on the switch front panel are for installing optional 5V GBIC transceivers. Note that GBIC transceivers are hot-swappable. You do not need to power off the switch before installing or removing a transceiver.

Network Management Agent

The TigerSwitch 1000 includes a built-in network management agent. The agent offers a variety of management options, including SNMP, RMON and a Web-based interface. The switch also provides a serial port on the rear panel for out-of-band management. This is an RS-232 serial port with a DB-9 connector. A PC may be connected to this port for configuration and monitoring purposes out-of band via a full-handshaking null-modem cable. (See Appendix B for a description of wiring options.)

The network management agent provides a wide range of advanced performance-enhancing features. Port-based and tagged VLANs provide traffic security and efficient use of network bandwidth. QoS priority queueing ensures the minimum delay for moving real-time multi-media data across the network. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. And broadcast storm suppression prevents broadcast traffic storms from engulfing the network. Some of the management features are described below. For a detailed description, refer to the Management Guide that is included with the switch.

1-4

ABOUT THE TIGERSWITCH 1000

Spanning Tree Protocol

The TigerSwitch 1000 supports ANSI/IEEE 802.1d Spanning Tree Protocol. This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, the protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network. This prevents the creation of network loops. However, if the chosen path should fail for any reason, an alternate path will be activated to maintain the connection.

The default setting for the Spanning Tree Protocol is “enabled.” This protocol may be configured (enabled or disabled) out-of-band via the serial console port or in-band via the Web interface, Telnet, or SNMP network management software.

VLANs

The TigerSwitch 1000 supports up to 256 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. By segmenting your network into VLANs, you can:

•Eliminate broadcast storms which severly degrade performance in a flat network.

•Simplify network management for node changes/moves by remotely configuring VLAN membership for the concerned port, rather than having to manually change the node’s IP address.

•Provide data security by restricting all traffic to the originating VLAN, except where a connection has been configured between separate VLANs using a router or Layer 3 switch.

1-5

ABOUT THE TIGERSWITCH 1000

Multicast Switching

Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping and IGMP to manage multicast group registration.

Traffic Priority

This switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using two distinct categories with Weighted Fair Queuing. It uses IEEE 802.1Q and 802.1p tags to prioritize incomming traffic based on input from the end-station application driver. These functions can be used, for example, to provide independent priorities for real-time video, real-time voice, guaranteed-delivery data, or best-effort data.

Optional Redundant Power Unit

SMC provides an optional Redundant Power Unit (RPU), SMCRPU150W, that can supply power to the switch in the event of failure of the internal power supply.

Power Supply Receptacles

There are two power receptacles on the rear panel of the switch. The standard power receptacle is for the AC power cord. The receptacle labeled “DC Input” is for the optional Redundant Power Unit (RPU).
