1 SuperStack II Switches Flexible, affordable 10/100/1000 stackable switches for boosting performance at the desktop, workgroup, and backbone The family of switches makes high-performance, low-cost switching a reality at the desktop, workgroup, and core. Now you can eliminate traffic bottlenecks with high-performance interswitch links, trunking, Gigabit Ethernet, or ATM connections. The only certainty in networks today is that bandwidth demands will continue to increase. As more complex and timesensitive applications such as voice and video feeds are created for the desktop, a higher volume of traffic is generated throughout the network. This results in network bottlenecks that can cause performance problems within workgroups, to and from servers, and across the backbone.

2 Switches for All Your Technology Needs Today, your desktop population probably requires a mix of 10 Mbps and 100 Mbps service to meet the individual demands of your users. As you deliver higher speeds to the desktop, connections to your servers may become strained, so it s vital that you have options that allow you to scale to 100 Mbps Fast Ethernet, ATM, or Gigabit Ethernet in the backbone. With the family of switches, you can support all of your bandwidth requirements with the appropriate technology Ethernet, Fast Ethernet, Gigabit Ethernet, and ATM all at the appropriate level of control. Ethernet Since it's inception Ethernet has been the most popular topology used to implement local area networks. Based on the IEEE standard, Ethernet has evolved over the years and now supports a range of media and significant enhancements compared to the original standard. The available bandwidth can be either shared across a number of users using hubs or dedicated to workstations using switched technology. Recently there has been a strong trend towards delivering dedicated 10Mbps links to the desktop which has been driven by the availability of low cost ethernet switches which have enabled the delivery of affordable high performance, high functionality networks. Fast Ethernet Fast Ethernet was designed to deliver higher levels of performance to bandwidth-intensive resources, such as servers, and desktop switches. Fast Ethernet is based on the Ethernet standard, which means it is a high-speed technology that runs over your existing infrastructure, works with your existing management In This Guide: Switches for All Your Technology Needs...2 Features Supported for Switches...4 Product Configurations (Diagrams) New Products Switch 1100 and Switch 3900 and Com Switches for All Your Needs Switch Switch Switch Switch Switch 1000 ATM Kit...14 Desktop Switch...15 Switch 3000 Family...16 Network Management...17 Switches at a Glance Specifications Ordering Information...24 systems, and requires no retraining by your IT staff. It is now one of the most popular high-speed technologies because of its cost-effectiveness, stability, and compatibility with existing Ethernet LAN environments. Fast Ethernet runs over 100BASE-FX fiber and 100BASE- TX copper. For greater performance, full-duplex is also supported over 100BASE-FX fiber. The challenge is to deliver Fast Ethernet bandwidth to power users or servers without disrupting users who are content with 10BASE-T. That s where auto-sensing 10/100 technology comes in. It combines both conventional 10BASE-T and high-speed 100BASE- TX support in one device. You can support Ethernet and Fast Ethernet traffic with one switch, delivering higher bandwidth to the desktop, aggregating 10/100 hubs, and maintaining the status quo for those who are efficiently served by 10 Mbps Ethernet. It is one of the most economical and flexible ways to add bandwidth immediately to congestion areas, while maintaining the option for migrations to higher bandwidth in the future. Gigabit Ethernet Gigabit Ethernet retains the traditional simplicity and manageability of Ethernet and Fast Ethernet making it easy to integrate with existing LAN equipment. It allows a tenfold increase (in backbone bandwidth) over Fast Ethernet with minimal impact on your support staff. The extra bandwidth helps you deal with unplanned changes and additions to the network, as well as freedom from constantly tuning the network. Gigabit Ethernet is a powerful backbone/server solution because it delivers phenomenal bandwidth cost effectively, preserves the Ethernet frame format, and works with your existing traffic management systems. ATM ATM is an established LAN backbone technology that offers significant benefits to larger organizations by providing tight integration between LAN and WAN environments and offering high levels of resilience and redundancy. In the LAN environment, OC-3 (155 Mbps) and OC-12 (622 Mbps) connections are used to communicate across the network. While these connections do not provide the raw bandwidth of Gigabit Ethernet, ATM provides alternative methods for delivering effective backbone solutions, such as Quality of Service (QoS), which guarantees bandwidth to applications. The control offered by ATM enables the deterministic delivery of applications and services in a complex network environments. 2

4 Features Supported for Switches Stackability Transcend network management support Web-based management Disconnect Unauthorized Device (Security) RMON support Roving Analysis Port IEEE 802.1p PACE technology Dual Queues Flow Contol (802.3 x/ifm) Intelligent Switching mode Switch 1100 Switch 3300 Switch 3900 Switch 9300 Switch 320 Switch 2200 Switch 2700 Switch 1000 ATM Kit Desktop Switch Switch 3000 Family Switch 9000 Full Duplex on all ports Features (described below) Stackability Four Switch 1100 or 3300 units can be interconnected to form a stack that offers unrivaled performance and management features. Each unit has a built-in connector at the rear of the unit called the Matrix Port. Two units can be connected back-to-back with a Switch Matrix Cable. To connect more than two units, a Matrix Module can be inserted into the highspeed module slot of one of the units in the stack, and a matrix cable can be used to connect to each switch in the stack. Management Transcend network management All switches are managed by 3Com Transcend network management architecture. Transcend software gives you end-toend visibility and control over all devices in your network with two levels of management: 1) embedded technologies, such as TranscendWare SmartAgent software and RMON, within 3Com devices throughout the network, and 2) centralized highly automated applications at the network center for monitoring, configuring, and troubleshooting all devices in the network. Web-based management Manage your switches with any Web browser, either through direct or dial-up connection or across the LAN. This delivers ease of use and accessibility to network management personnel and reduces in-service costs, but still with full security. Security Disconnect Unauthorized Device (DUD) LAN security architecture with DUD automatically disconnects unauthorized devices from the LAN. Roving Analysis Port (RAP) RAP allows a network analyzer attached to any unit in a stack to monitor any of the switch ports or VLANs in the stack. It also minimizes the time required for problem determination and resolution and maximizes switch uptime, thereby lowering your cost of ownership. RMON support Transcend software's powerful combination of RMON (Remote Monitoring, a superset of SNMP MIB II) and TranscendWare SmartAgent software reduces the processing burden on your management station, minimizes network traffic, and saves time by automatically monitoring and analyzing your network. RMON tells you at a glance how the network is performing and who is using it the most. And Transcend software gives you the added benefit of RMON features in your network without the processing and memory costs usually associated with RMON. See the At-a-Glance RMON Support table on page 20 for details on RMON groups supported by switches. Class of Service (CoS) CoS can be defined simply as a method for prioritizing various traffic types. 3Com switches can support two methods of enabling CoS on Ethernet networks. The first method is IEEE 802.1p, which enables eight levels of prioritization; and the second method is 3Com's innovative PACE technology, which allows the user to specify certain applications as high priority. A unique hardware feature, Dual Queues, is used to exploit these traffic prioritization schemes; the Dual Queues function will automatically enable a second port buffer for high-priority traffic thereby allowing the traffic to bypass lower priority data for faster processing within the switch. Traffic Management Flow Control Flow control is an essential switch feature needed to eliminate dropped packets on congested ports. In order to provide flexibility in terms of switch application, 3Com switches support flow control schemes suited to both full- and half-duplex environments. 4

5 Resilient links Broadcast Traffic Control Backup power supplies UPS and ARPS Intelligent Flow Management (IFM) is a solution designed to work in half duplex, for example, a hub aggregation application. A solution using IEEE 802.3x is also supported and designed for full-duplex connections, such as desktop switching; this method of flow control is set automatically using the auto-sensing features of switches. Broadcast traffic control Traditional Ethernet switches suffer from the threat of broadcast storms that can potentially bring networks to a halt. However, all switches can be configured with broadcast storm protection in order to limit the number of broadcast packets allowed to be forwarded by each port. This allows the switches to offer the security of broadcast storm protection normally associated with a router while also providing the protocol independence of a switch. Network Availability Spanning Tree Trunking Backup power supplies 3Com gives you all the choices you need to ensure constant power to your stackable switches. Both the Advanced Redundant Power System (ARPS) and the Uninterruptible Power System (UPS) work with any switch. The ARPS is ideally suited as a backup for individual VLAN (802.1Q /VLT) Multicast filtering using IGMP snooping Fast IP IP routing power supplies in the units. The UPS fully protects your system from the effects of brownouts or spikes that occur in outside power lines. Resilient links 3Com's simple and flexible Resilient Links technology ensures fault tolerance via redundant connections to other network devices. Spanning tree Support for the industry-standard IEEE 802.1d spanning tree protocol is provided as an alternative to resilient links. This gives protection against network loops and can be used to provide redundant network paths. Port trunking Port trunking allows backbone links to be established by treating multiple parallel links as a single network pipe. To utilize these high-speed pipes, users are not required to network protocols. Trunking also provides link redundancy; traffic on any failed link comprising a network trunk automatically switches over to the other links. VLANs VLANs allow PCs, workstations, and other resources, including printers and file servers, to be organized into logical, broadcast domains so that only devices within the same domain can communicate with each other. 3Com switches allow users to implement VLANs on their network using one of two schemes: IEEE 802.1Q, including GVRP, which enables the auto-learning of VLANS, or 3Com's VLT. Both methods allow for the configuration of VLANs based on ports and/or MAC addresses for maximum flexibility and security. For 802.1Q VLANs a port on a switch can be assigned to a VLAN, all other switches learn about that VLAN since the switches automatically communicate that knowledge via the GVRP protocol. Switches supporting both VLAN schemes can be used to provide seamless migration from VLT to IEEE 802.1Q environments to preserve investment in current LAN developments and equipment. Layer 3 Support Multicast filtering using IGMP snooping Multicast filtering enables the automatic configuration of filters for IP multicast traffic, such as video and audio broadcasts, allowing advanced multimedia applications to be delivered easily to the workgroup. Fast IP Fast IP is 3Com s standards based IP switching solution for all types of legacy network backbones. The switches support IEEE 802.1Q and IEEE 802.1p to provide the required switch support for a Fast IP solution. Routers provide the necessary NHRP support to complete the solution. Wire-speed IP routing Embedding in ASIC technology wire-speed IP routing, in addition to Gigabit Ethernet, allows a dramatic performance increase in corporate intranets. The routing of intranet traffic is offloaded from legacy routers, while the security and broadcast containment of IP subnetting is retained. 5

Plus, you get 2 Gbps (full-duplex) bandwidth 10 times the bandwidth of Fast Ethernet without changing your existing switching platforms. The Switch Gigabit Ethernet SX module complements the 3Com Switch 9000 so you can implement an end-toend Gigabit Ethernet network solution, from the desktop to the backbone. Switch ATM 0C-3c Module The ATM OC-3c module provides support for the ATM Forum Standards for LAN Emulation (LANE 1.0) allowing existing Fast Ethernet and Ethernet LAN users to communicate transparently over a high-speed ATM backbone. Full-duplex operation gives wire speeds of 310 Mbps, virtually eliminating network bottlenecks. Low latency of 68 microseconds from Ethernet to ATM provides increased network performance. The ATM OC-3c module absorbs traffic peaks to prevent packet loss due to the deep 40,000 cells (2 MB) buffer. Support for the ATM Forum LANE standard allows existing LAN users to communicate over the high-speed ATM network and provides investment protection for existing Ethernet NICs, hubs, switches, and routers. 15

16 Switch 3000 Family The Switch /100 supports Ethernet and Fast Ethernet switching in one 12-port stackable switch. Full- and half-duplex support on all ports ensures 200 Mbps bandwidth to each connected device. The Switch /100 incorporates standards-based autosensing technology, which enables the switch to detect Ethernet or Fast Ethernet connections. Plus, they support up to 8,160 MAC addresses for the largest, high-performance networks. The Switch 3000 FX supplies five 100BASE-FX (fiber) ports and one 100BASE-TX (twistedpair copper) port for workgroup devices and backbones. An optional 10 Mbps transceiver interface is also available for the 3000 FX switch. The Switch 3000 TX offers eight 100BASE-TX ports for floor configurations. The Switch 3000 FX and 8-port TX switches support up to 4,080 MAC addresses, extending bandwidth to large networks servicing many users. All Switch 3000 models offer a slot for an optional, high-speed module, including a module that provides an extra Fast Ethernet high-speed port 100BASE-TX or 100BASE-FX or ATM OC-3c multimode or Gigabit Ethernet 1000BASE-SX.
