Overview

SMC’s TigerSwitch™ 10/100 is a Fast Ethernet switch with 48 10BASE-T/100BASE-TX ports, plus two slots for optional slide-in 100BASE-FX or 1000BASE-SX modules. There is also an SNMP-based Network Management Module installed in the rear panel. This module supports both in-band and out-of-band access for managing the switch.

Switch Architecture

The TigerSwitch employs a high-speed switching fabric. This design allows for simultaneous transport of multiple packets at low latency on all ports. It also uses store-and-forward switching to ensure maximum data integrity. In this mode, the entire packet must be received into a port buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

This TigerSwitch can be used in a standalone configuration, supporting up to 52 ports. Moreover, you can use a 100 Mbps fiber module for connecting to a remote site, or a Gigabit module for a high-speed backbone connection.

1-2

BOUT THE TIGERSWITCH

Management Options

This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status. It also includes a Network Management Module that allows the switch to be managed in-band via SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or remotely via Telnet. The switch also provides a serial port on the rear panel for out-of-band management.

There is also support for a Redundant Power Unit to ensure continuous operation in the event of a power failure.

Description of Hardware

10BASE-T/100BASE-TX Ports (SMC6948L2)

These ports are dual-speed RJ-45 ports with built-in wiring crossovers (MDI-X). Workstations and servers can be connected to these ports with straight-through cable. When connecting to another switch or a hub, you can use straight-through cable to connect to a port on the attached device that does not have built-in wiring crossovers (MDI), or use crossover cabling. (See Appendix B for a pinout description of crossover cable.)

10/100

Each of these ports support 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 IEEE 802.3x auto-negotiation of full-duplex flow control, so the switch can automatically prevent port buffers from becoming saturated.

Network Management Module

Figure 1-4. Network Management Module

This switch includes a Network Management Module on the rear panel. It offers a variety of management options, including SNMP, RMON and a Web-based interface. This module also includes an RS-232 port 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 fullhandshaking null-modem cable. You can also make a remote connection to this port via modems. This allows you to access the out-of-band interface. (See Appendix B for a description of wiring options.)

The Network Management Module provides a wide range of advanced performance-enhancing features. Multicast filtering provides support for real-time network applications. Port-based and tagged VLANs, plus support for automatic GVRP VLAN 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. And broadcast storm control prevents broadcast traffic storms from engulfing the network.

10/100

Some of this switch’s advanced features are described below. For a detailed description, refer to the Management Guide.

BOUT THE TIGERSWITCH

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, this 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 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:

10/100

• 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.

• Provides 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.

1-6

BOUT THE TIGERSWITCH

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 802.1p 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.

Optional Media Extender Modules

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).

Features and Benefits

Connectivity

◆ 48 dual-speed ports for easy Fast Ethernet integration and for protection of your investment in legacy LAN equipment

◆ Auto-negotiation enables each RJ-45 port to automatically select the optimum communication mode (half or full duplex) if this feature is supported by the attached device; otherwise the port can be configured manually

◆ Independent RJ-45 10BASE-T/100BASE-TX ports with built-in wiring crossovers for straight-through cable connections

◆ Unshielded (UTP) cable supported on all RJ-45 ports: Category 3, 4 or 5 for 10 Mbps connections and Category 5 for 100 Mbps connections

10/100

◆ IEEE 802.3 Ethernet and 802.3u Fast Ethernet compliance ensures compatibility with standards-based hubs, network cards and switches from any vendor

Expandability

◆ Optional 100BASE-FX fiber module (SC connector) which can connect to a remote site up to 2 kilometers away (at full duplex)

◆ Optional 1000BASE-SX Gigabit module that can run up to 550 meters (using 50/125 micron, 500 MHz/km fiber cable), and operates at 1 Gbps, half or full duplex, with auto-negotiation for duplex mode and flow control
