10/100

SMC’s TigerSwitch™ 10/100 is an intelligent multilayer (Layer 2 and 3) switch with 24 10BASE-T/100BASE-TX ports plus two slots on the rear panel for slide-in 1000BASE-LX, 1000BASE-SX, 1000BASE-T or 100BASE-FX modules. This switch can easily tame your network with full support for Spanning Tree Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to poorly performing networks by segregating them into separate broadcast domains with IEEE 802.3Q compliant VLANs, empowers multimedia applications with multicast switching and QoS services, and eliminates conventional router bottlenecks.

It can be used to augment or completely replace slow legacy routers, off-loading local IP traffic to release valuable resources for non-IP routing or WAN access. With wire-speed performance for both Layer 2 switching and Layer 3 routing, this switch can significantly improve the throughput between IP segments or VLANs.

Switch Architecture

The TigerSwitch 10/100 employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

Switching Method

For communications between different VLANs, this switch uses IP routing with RIP, RIPv2, OSPFv2 or DVMRP protocol. For communications within the same VLAN, the switch uses store-and-forward switching to ensure maximum data integrity. In store-and-forward switching mode, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

Management Options

This switch contains a comprehensive array of LEDs for “at-a- glance” monitoring of network and port status. It also includes a built-in network management agent that allows the switch to be managed in-band using SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or remotely via Telnet. The switch provides an RS-232 serial port (DB-9 connector) on the rear panel for out-of-band management. A PC may be connected to this port for configuration and monitoring out-of band via a full-handshaking null-modem cable. You can also make a remote connection to this port via modems. (See Appendix B for wiring options.)

This switch provides a wide range of advanced performanceenhancing features. Port-based and tagged VLANs, plus support for automatic GVRP VLAN registration and GMRP multicast group registration provide traffic security and efficient use of network bandwidth. QoS priority queueing ensures the minimum delay for moving real-time multimedia data across the network. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. Broadcast storm control prevents broadcast traffic storms from engulfing the network. Layer 3 routing can be used to connect segregated subnets and VLANs. Some of this switch’s advanced features are described below. For a detailed description, refer to the Management Guide.

10/100

Spanning Tree Protocol

The TigerSwitch 10/100 supports 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.

1-3

Page 20

BOUT THE TIGERSWITCH

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

VLANs

The TigerSwitch 10/100 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 severely degrade performance in a flat network.

• Simplify network management for node changes/moves by remotely configuring VLAN membership for any 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 is explicitly defined via the switch’s routing service.

10/100

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 GMRP at Layer 2, and IGMP at Layer 3 to manage multicast group registration.

1-4

Page 21

BOUT THE TIGERSWITCH

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 802.1p and

802.1Q tags to prioritize incoming traffic based on input from the end-station application. These functions can be used to provide independent priorities for delay-sensitive data and best-effort data.

Layer 3 Routing

The TigerSwitch 10/100 provides Layer 3 IP routing. To maintain a high rate of throughput, the switch forwards all intra-segment traffic, and routes only traffic that passes outside the segment. By providing wire-speed routing, you can easily link your network segments or VLANs together without having to deal with the bottlenecks or configuration hassles normally associated with conventional routers.

Most traffic can be routed based on information maintained within the switch’s own database. If the address is not in the switching database, the switch will use RIP, RIPv2 or OSPFv2 protocol to request the address. If the address still cannot be found, the switch can pass the packet to a default router for handling.

10/100

The switch uses DVMRP protocol to determine the routing for multicast packets. If no hosts have subscribed to the indicated multicast service, the packet will be dropped.

Description of Hardware

10BASE-T/100BASE-TX Ports

These are dual-speed RJ-45 ports. Because all ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See“100BASE-TX/10BASE-T Pin Assignments” on page B-3.)

Each of these ports support IEEE 802.3x auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually.

Each port also supports auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.

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

When performance bottlenecks are caused by congestion at the network access point (such as the network card for a high-volume file server), the device experiencing congestion (server, power user or hub) can be attached directly to a switched port. And, by using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the maximum distance between end stations is limited. For Ethernet, there may be up to four hubs between any pair of stations; for Fast Ethernet, the maximum is two. This is known as the hop count. However, a switch turns the hop count back to zero, so subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.

A switch can be easily configured in any Ethernet or Fast Ethernet network to significantly boost bandwidth while using conventional cabling and network cards.

Sample Applications

The TigerSwitch 10/100 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 TigerSwitch 10/100 is an excellent choice for mixed Ethernet and Fast Ethernet installations where significant growth is expected in the near future. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers. When the time comes for further expansion, just cascade the TigerSwitch to an Ethernet or Fast Ethernet hub or switch.

In the figure below, the TigerSwitch 10/100 is operating as a collapsed backbone for a small LAN. It is providing dedicated 20 Mbps full-duplex connections to workstations and 200 Mbps fullduplex connections to power users and servers.

With 24 parallel bridging ports (i.e., 24 distinct collision domains), the TigerSwitch 10/100 can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.

In the figure below, the 10BASE-T/100BASE-TX ports on the TigerSwitch are providing 100 Mbps connectivity for up to 24 segments through SMC’s TigerStack II 10/100 hubs. In addition, the switch is also connecting servers at 200 Mbps.

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A 100 Mbps multimode fiber (MMF) link can run up to 2 km, and a 100 Mbps single-mode fiber (SMF) link can run as far as 20 km. A 1000BASE-LX SMF Gigabit link can also connect to a site up to 5 km away. This allows the TigerSwitch 100 to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. The 100BASE-FX SMF module can be used to interconnect remote Fast Ethernet segments. While a Gigabit module can be used for a high-speed connection between floors in the same building, or to connect to other buildings in a campus setting. The figure below illustrates a TigerSwitch 100 stack connecting multiple segments with fiber cable.

Making VLAN Connections

VLANs can be based on port groups, or each data frame can be explicitly tagged to identify the VLAN group it belongs to. When using port-based VLANs, ports can either be assigned to one specific group or to all groups. 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, it is therefore better to use VLAN tagging. This allows you to assign multiple VLAN groups to the “trunk” ports (that is, tagged ports) connecting different switches.

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 therefore 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.

Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for Ethernet, Fast Ethernet, or Gigabit Ethernet.

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. When a switch is connected to a hub or any kind of shared

media, remember to turn off back pressure to prevent the attached port from being frequently partitioned due to the jamming packets.

3. For network applications that require routing between

dissimilar network types, you can attach the TigerSwitch 10/100 units directly to a router. However, if you have to interconnect distinct VLANs or IP subnets, you can take advantage of the Layer 3 routing provided by this switch.

4. The modules are fitted with SC connectors, but you can attach

an ST plug to the switch using SMC’s optional SC-to-ST plug converter (Part Number: 99-012034-091, for 62.5/125 micron cable only). 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.

5. As a general rule:

- the length of Gigabit fiber optic cable for a single switched link should not exceed 550 m (1805 ft) for multimode fiber or 5 km (16404 ft) for single-mode fiber.

- the length of 100BASE-FX fiber optic cable for a single switched link should not exceed 2km (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.

◆ Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.

◆ Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.

◆ Grounding: Rack-mounted equipment should be properly grounded. Particular attention should be given to supply connections other than direct connections to the mains.

Installing an Optional Module into the Switch

Caution: DO NOT install slide-in modules with the switch

powered on. Be sure you power off the switch before installing any module.

To install an optional module into the switch, do the following:

1. Disconnect power to the switch.

2. Remove the blank metal plate (or a previously installed module) from the appropriate slot by removing the two screws with a flat-head screwdriver.

3. Before opening the package that contains the module, touch the bag to the switch casing to discharge any potential static electricity. Also, it is recommended to use an ESD wrist strap during installation.

4. Remove the module from the anti-static shielded bag.

5. Holding the module level, guide it into the carrier rails on each side and gently push it all the way into the slot, ensuring that it firmly engages with the connector.

Connecting Network Devices

The TigerSwitch 10/100 is designed to interconnect multiple segments (or collision domains). It may be connected to network cards in PCs and servers, as well as to Ethernet and Fast Ethernet hubs, switches or routers. It may also be connected to devices using the optional 1000BASE-LX, 1000BASE-SX, 1000BASE-T or 100BASE-FX modules.

Note: Before connecting cables, you may want to first configure

the Spanning Tree Protocol to avoid network loops. Refer to the Management Guide for more information.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. For 100BASE-TX connections, Category 5 cable is required; for 10BASE-T, Category 3, 4 or 5 cable can be used.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X operation, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).

See Appendix B for further information on cabling.

Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.

AKING NETWORK CONNECTIONS

Connecting to PCs, Servers, Hubs and Switches

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

Figure 4-1. Making Twisted-Pair Connections

2. If the device is a network card and the TigerSwitch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet (see “Wiring Closet Connections” on the next page). Otherwise, attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

Note: When connected to a shared collision domain (such as a

hub with multiple workstations), switch ports must be set to half-duplex mode and back pressure flow control disabled.

3. As each connection is made, the green Link LED (on the TigerSwitch) corresponding to each port will light to indicate that the connection is valid.

Fiber Optic Devices

An optional slide-in 100BASE-FX module may be used for backbone and long distance connections. A 1000BASE-X module may also be used for a backbone connection between switches, or for connecting to a high-speed server.

Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at both ends. If you need to connect to a device with 62.5/125 micron cable that has ST-type connectors, SMC provides an optional SC-ST Converter (Part Number: 99-012034-091).

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an SC connector at both ends.

Caution: This switch uses lasers to transmit signals over fiber

optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

1. Remove and keep the SC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

4-5

Page 54

AKING NETWORK CONNECTIONS

3. Connect one end of the cable to the SC port on the switch and the other end to the SC port on the other device. Since SC connectors are keyed, the cable can be attached in only one orientation.

Figure 4-3. Making SC Port Connections

4. As a connection is made, check the green Link LED on the switch corresponding to the port to be sure that the connection is valid.

Note: If you use the optional SC-ST Converter, be sure to connect

the converter’s Tx (Rx) port to the Rx (Tx) port on the other device.

The 100BASE-FX fiber optic ports operate only at 100 Mbps, full duplex. You can run a single-mode fiber link up to 20 kilometers (12.43 miles). However, note that power budget constraints must also be considered when calculating the maximum cable length for your specific environment.

The 1000BASE-SX and 1000BASE-LX fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet Collision Domain” on page 2-7.

ROUBLESHOOTING

Diagnosing Switch Indicators

Troubleshooting Chart

Symptom Action

Power LED is Off • Internal or redundant power supply has failed or

is disconnected.

• Check connections between the switch, the power cord, the wall outlet, and the RPU if you are using one.

• Contact SMC Tech Support.

Power LED is Flashing • The switch is either downloading firmware or

running the Power-On Self-Diagnostics Test (POST). If this LED does not stop flashing, then POST has failed, and you should contact SMC Technical Support.

Link LED is Off • Verify that the switch and attached device are

powered on.

• Be sure the cable is plugged into both the switch and corresponding device.

• Verify that the proper cable type is used and its length does not exceed specified limits.

• Check the adapter on the attached device and cable connections for possible defects. Replace the defective adapter or cable if necessary.

ROUBLESHOOTING

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact SMC Technical Support for assistance.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

In-Band Access

You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software such as EliteView. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

Twisted-Pair Cable and Pin Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45

port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors

in a specific orientation. (See “Cabling Guidelines” on page 4-2 for an explanation.)

Figure B-1 illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3ab standards.

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

ABLES

Note that when testing your cable installation, be sure to include all patch cables between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem:

1. Replace any Category 5 patch cables with high-performance Category 5e cables.

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.

IEEE 802.3ab specification for Gigabit Ethernet over 100-ohm Category 5 or 5e twisted-pair cable (using all four wire pairs).

Auto-Negotiation

Signalling method allowing each node to select its optimum operational mode (e.g., 10 Mbps or 100 Mbps and half or full duplex) based on the capabilities of the node to which it is connected.

Glossary-1

Page 78

LOSSARY

Bandwidth

The difference between the highest and lowest frequencies available for network signals. Also synonymous with wire speed, the actual speed of the data transmission along the cable.

Collision

A condition in which packets transmitted over the cable interfere with each other. Their interference makes both signals unintelligible.

Collision Domain

Single CSMA/CD LAN segment.

CSMA/CD

CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication method employed by Ethernet, Fast Ethernet, or Gigabit Ethernet.

End Station

A workstation, server, or other device that does not forward traffic.

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 CSMA/CD access method.

Glossary-2

Page 79

Gigabit Ethernet

A 1000 Mbps network communication system based on Ethernet and the CSMA/CD access method.

Full Duplex

Transmission method that allows two network devices to transmit and receive concurrently, effectively doubling the bandwidth of that link.

IEEE

Institute of Electrical and Electronic Engineers.

IEEE 802.3

Defines carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications.

IEEE 802.3u

Defines CSMA/CD access method and physical layer specifications for 100BASE Fast Ethernet.

LOSSARY

IEEE 802.3x

Defines Ethernet frame start/stop requests and timers used for flow control on full-duplex links.

IEEE 802.3z

Defines CSMA/CD access method and physical layer specifications for 1000BASE Gigabit Ethernet.

Local Area Network (LAN)

A group of interconnected computer and support devices.

LAN Segment

Separate LAN or collision domain.

Glossary-3

LOSSARY

LED

Light emitting diode used for monitoring a device or network condition.

Local Area Network

A group of interconnected computers and support devices.

Media Access Control (MAC)

A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes.

MIB

An acronym for Management Information Base. It is a set of database objects that contains information about the device.

Network Diameter

Wire distance between two end stations in the same collision domain.

Open Shortest Path First (OSPF)

OSPF is a link state routing protocol that functions better over a larger network such as the Internet, as opposed to distance vector routing protocols such as RIP. It includes features such as unlimited hop count, authentication of routing updates, and Variable Length Subnet Masks (VLSM).

Redundant Power Unit (RPU)

A backup power supply that automatically takes over in case the primary power supply should fail.

RJ-45 Connector

A connector for twisted-pair wiring.

Glossary-4

Page 81

Routing Information Protocol (RIP)

The RIP protocol attempts to find the shortest route to another device by minimizing the distance vector, or hop count, which serves as a rough proxy for transmission cost. RIP-2 is a compatible upgrade to RIP. It adds useful capabilities for subnet routing, authentication, and multicast transmissions.

Straight-through Port

An RJ-45 port which does not cross the receive and transmit signals internally (MDI) so it can be connected with straight-through twisted-pair cable to any device having a crossover port (MDI-X). Also referred to as a “Daisy-Chain” port.

Switched Ports

Ports that are on separate collision domains or LAN segments.

Transmission Control Protocol/Internet Protocol (TCP/IP)

Protocol suite that includes TCP as the primary transport protocol, and IP as the network layer protocol.

LOSSARY

UTP

Unshielded twisted-pair cable.

Virtual LAN (VLAN)

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. A VLAN serves as a logical workgroup with no physical barriers, allowing users to share information and resources as though located on the same LAN.
