SuperStack IISwitches for All YourTechnology NeedsToday, your desktop population probablyrequires a mix of 10 Mbps and 100 Mbpsservice to meet the individual demands ofyour users. As you deliver higher speeds tothe desktop, connections to your serversmay become strained, so it’s vital that youhave options that allow you to scale to 100Mbps Fast Ethernet, ATM, or GigabitEthernet in the backbone. With theSuperStack II family of switches, you cansupport all of your bandwidth requirementswith the appropriate technology—Ethernet,Fast Ethernet, Gigabit Ethernet, and ATM—all at the appropriate level of control.

EthernetSince it's inception Ethernet has been themost popular topology used to implementlocal area networks. Based on the IEEE802.3 standard, Ethernet has evolved overthe years and now supports a range ofmedia and significant enhancements com-pared to the original standard. The avail-able bandwidth can be either sharedacross a number of users using hubs ordedicated to workstations using switchedtechnology. Recently there has been astrong trend towards delivering dedicated10Mbps links to the desktop which hasbeen driven by the availability of low costethernet switches which have enabled thedelivery of affordable high performance,high functionality networks.

Fast EthernetFast Ethernet was designed to deliverhigher levels of performance to band-width-intensive resources, such as servers,and desktop switches. Fast Ethernet isbased on the Ethernet standard, whichmeans it is a high-speed technology thatruns over your existing infrastructure,works with your existing management

systems, and requires no retraining byyour IT staff. It is now one of the mostpopular high-speed technologies becauseof its cost-effectiveness, stability, andcompatibility with existing EthernetLAN environments. Fast Ethernet runsover 100BASE-FX fiber and 100BASE-TX copper. For greater performance, full-duplex is also supported over100BASE-FX fiber.

The challenge is to deliver FastEthernet bandwidth to power users orservers without disrupting users who arecontent with 10BASE-T. That’s whereauto-sensing 10/100 technology comesin. It combines both conventional10BASE-T and high-speed 100BASE-TX support in one device. You can sup-port Ethernet and Fast Ethernet trafficwith one switch, delivering higher band-width to the desktop, aggregating 10/100hubs, and maintaining the status quo forthose who are efficiently served by 10Mbps Ethernet. It is one of the most eco-nomical and flexible ways to add band-width immediately to congestion areas,while maintaining the option for migra-tions to higher bandwidth in the future.

Gigabit EthernetGigabit Ethernet retains the traditionalsimplicity and manageability of Ethernetand Fast Ethernet making it easy to inte-

grate with existing LAN equipment. Itallows a tenfold increase (in backbonebandwidth) over Fast Ethernet with mini-mal impact on your support staff. Theextra bandwidth helps you deal withunplanned changes and additions to thenetwork, as well as freedom from con-stantly tuning the network. GigabitEthernet is a powerful backbone/serversolution because it delivers phenomenalbandwidth cost effectively, preserves theEthernet frame format, and works withyour existing traffic management systems.

ATMATM is an established LAN backbonetechnology that offers significant benefitsto larger organizations by providing tightintegration between LAN and WAN envi-ronments and offering high levels ofresilience and redundancy. In the LANenvironment, OC-3 (155 Mbps) and OC-12 (622 Mbps) connections are usedto communicate across the network.While these connections do not providethe raw bandwidth of Gigabit Ethernet,ATM provides alternative methods fordelivering effective backbone solutions,such as Quality of Service (QoS), whichguarantees bandwidth to applications. Thecontrol offered by ATM enables the deter-ministic delivery of applications and ser-vices in a complex network environments.

Features(described below)

StackabilityFour SuperStack II Switch 1100 or 3300units can be interconnected to form a stackthat offers unrivaled performance and man-agement features.

Each unit has a built-in connector at therear of the unit called the Matrix Port. Twounits can be connected back-to-back with aSuperStack II Switch Matrix Cable. To con-nect more than two units, a SuperStack IIMatrix Module can be inserted into the high-speed module slot of one of the units in thestack, and a matrix cable can be used to con-nect to each switch in the stack.

ManagementTranscend network managementAll SuperStack II switches are managed by3Com Transcend network management archi-tecture. Transcend software gives you end-to-end visibility and control over all devices inyour network with two levels of management:1) embedded technologies, such asTranscendWare™ SmartAgent® software andRMON, within 3Com devices throughout thenetwork, and 2) centralized highly automatedapplications at the network center for moni-toring, configuring, and troubleshooting alldevices in the network.

Web-based management

Manage your switches with any Webbrowser, either through direct or dial-up con-nection or across the LAN. This delivers easeof use and accessibility to network manage-ment personnel and reduces in-service costs,but still with full security.

Security—Disconnect UnauthorizedDevice (DUD)

LAN security architecture with DUD auto-matically disconnects unauthorized devicesfrom the LAN.

Roving Analysis Port (RAP)

RAP allows a network analyzer attached toany unit in a stack to monitor any of theswitch ports or VLANs in the stack. It alsominimizes the time required for problemdetermination and resolution and maximizesswitch uptime, thereby lowering your cost ofownership.

RMON supportTranscend software's powerful combinationof RMON (Remote Monitoring, a superset ofSNMP MIB II) and TranscendWareSmartAgent software reduces the processingburden on your management station, mini-mizes network traffic, and saves time byautomatically monitoring and analyzing yournetwork. RMON tells you at a glance howthe network is performing and who is using itthe most. And Transcend software gives you

the added benefit of RMON features in yournetwork without the processing and memorycosts usually associated with RMON. See theAt-a-Glance RMON Support table on page20 for details on RMON groups supported bySuperStack II switches.

Class of Service (CoS)CoS can be defined simply as a method forprioritizing various traffic types. 3Comswitches can support two methods ofenabling CoS on Ethernet networks. The firstmethod is IEEE 802.1p, which enables eightlevels of prioritization; and the secondmethod is 3Com's innovative PACE™ tech-nology, which allows the user to specify cer-tain applications as high priority. A uniquehardware feature, Dual Queues, is used toexploit these traffic prioritization schemes;the Dual Queues function will automaticallyenable a second port buffer for high-prioritytraffic thereby allowing the traffic to bypasslower priority data for faster processingwithin the switch.

Traffic Management Flow ControlFlow control is an essential switch featureneeded to eliminate dropped packets on con-gested ports. In order to provide flexibility interms of switch application, 3Com switchessupport flow control schemes suited to bothfull- and half-duplex environments.

Resilient links

3Com's simple and flexible Resilient Linkstechnology ensures fault tolerance via redun-dant connections to other network devices.

Spanning tree

Support for the industry-standard IEEE802.1d spanning tree protocol is provided asan alternative to resilient links. This givesprotection against network loops and can beused to provide redundant network paths.

Port trunking

Port trunking allows backbone links to beestablished by treating multiple parallel linksas a single network pipe. To utilize thesehigh-speed pipes, users are not required tonetwork protocols. Trunking also provideslink redundancy; traffic on any failed linkcomprising a network trunk automaticallyswitches over to the other links.

VLANs VLANs allow PCs, workstations, and otherresources, including printers and file servers,to be organized into logical, broadcastdomains so that only devices within the samedomain can communicate with each other.3Com switches allow users to implementVLANs on their network using one of twoschemes: IEEE 802.1Q, including GVRP,which enables the auto-learning of VLANS,or 3Com's VLT. Both methods allow for theconfiguration of VLANs based on portsand/or MAC addresses for maximum flexibil-ity and security. For 802.1Q VLANs a port ona switch can be assigned to a VLAN, all otherswitches learn about that VLAN since theswitches automatically communicate thatknowledge via the GVRP protocol.

Switches supporting both VLANschemes can be used to provide seamlessmigration from VLT to IEEE 802.1Q envi-ronments to preserve investment in currentLAN developments and equipment.

Layer 3 Support

Multicast filtering using IGMP snooping

Multicast filtering enables the automatic con-figuration of filters for IP multicast traffic,such as video and audio broadcasts, allowingadvanced multimedia applications to bedelivered easily to the workgroup.

Fast IPFast IP is 3Com’s standards based IP switch-ing solution for all types of legacy networkbackbones. The SuperStack II switches sup-port IEEE 802.1Q and IEEE 802.1p to pro-vide the required switch support for a Fast IPsolution. Routers provide the necessaryNHRP support to complete the solution.

Wire-speed IP routing Embedding in ASIC technology wire-speedIP routing, in addition to Gigabit Ethernet,allows a dramatic performance increase incorporate intranets. The routing of intranettraffic is offloaded from legacy routers, whilethe security and broadcast containment of IPsubnetting is retained.

Intelligent Flow Management (IFM) is asolution designed to work in half duplex, forexample, a hub aggregation application. Asolution using IEEE 802.3x is also supportedand designed for full-duplex connections,such as desktop switching; this method offlow control is set automatically using theauto-sensing features of SuperStack IIswitches.

Broadcast traffic controlTraditional Ethernet switches suffer from thethreat of broadcast storms that can potentiallybring networks to a halt. However, allSuperStack II switches can be configuredwith broadcast storm protection in order tolimit the number of broadcast packetsallowed to be forwarded by each port. Thisallows the SuperStack II switches to offer the security of broadcast storm protection nor-mally associated with a router while also pro-viding the protocol independence of a switch.

Network Availability Backup power supplies3Com gives you all the choices you need toensure constant power to your stackableswitches.

Specifications (Continued)

ManagementAll switches support SNMP and3Com Transcend network manage-ment applications.

SuperStack II Switch 1100 andSuperStack II Switch 3300The Switch 1100 and 3300 can bemanaged locally with a CommandLine Interface by connecting a ter-minal to the serial port or viaTelnet, or graphically using the resident Web interface or withTranscend network management.

MIBs supported: MIB II (RFC1213), Bridge MIB (RFC 1493),RMON (RFC 1757), RMON II

Plus additional 3Com SuperStack IIMIBs for stacking, security, andresilience.

SuperStack II Switch 3900 andSuperStack II Switch 9300The SuperStack II Switch 3900 andSuperStack II Switch 9300 includean RS 232 port for configurationand management with theSuperStack II Switch 9300 alsoincluding a 10 Mbps Ethernet console port.

SuperStack II Switch 3900 andSuperStack II Switch 9300 can bemanaged remotely from a PC run-ning 3Com’s TranscendWorkGroup Manager or TranscendEnterprise Manager for Windows,or from a workstation running3Com’s Transcend EnterpriseManager for UNIX. Alternatively,the SuperStack II Switch 3900 andSuperStack II Switch 9300 portscan be managed using Telnet.Supported in Version 1.0, Web-browser and multiple Telnetsessions in Version 1.1.

MIBs supported: MIB-II, BridgeMIB, Ethernet MIB, Virtual LANMIB, RMON MIB

Distributed RMON capability pro-vides per-port support for Alarms,Events, Statistics, History, Host,HostsTopN, and Matrix groups.The first four groups are supportedin Version 1.0 of the firmware. The last three groups are supportedin Version 1.1 of the firmware. For those network managers whowant to gather all nine RMONgroups on a specific port/segment, aMirror Port function is provided forboth Fast Ethernet and Gigabit

Ethernet ports. This allows the net-work manager to attach an externalprobe to any port on the switch andmonitor the traffic on any other likeport on the switch.
