ScalabilityEnhanced 10/100/1000 Layer 2 switchingand dynamic Layer 3 routing solutiondelivers scalable wirespeed Gigabit perform-ance, with integrated stacking up to eightunits high, or 384 Gigabit ports. Each Switchcomes with integrated dual full duplex10Gbps stacking ports on the back of theunit, providing a total stacked capacity of40Gbps, plus an expansion slot capable ofsupporting an additional 10Gbps full duplex(20Gbps total) high-speed Ethernet connec-tion. This enables the 156Gbps switchingcapacity to provide wirespeed switching onall ports.Stack-wide link aggregation enables high-performance connectivity to the core of thenetwork, with up to eight ports fromdifferent units aggregated together toimprove resiliency and uptime.Performance24 or 48 built-in copper Gigabit ports,including four dual-purpose portssupporting copper links or SFP adapters foreasy, flexible connection to fiber basedGigabit media. Port-based rate-limitingenables the bandwidth on each port to berestricted, so power users can receive thefull bandwidth available while non-key userscan be throttled down, preserving networkbandwidth and allowing maximum controlof network resources. Built-in packet priori-tization gives optimal performance toreal-time applications such as voice andvideo.Future ProtectionGigabit to the desk prepares your networkfor the future at prices comparable to thoseof some 10/100 switches. Tri-speed opera-tion at 10-, 100-, and 1000Mbps allows easymigration to Gigabit speeds. Investmentprotection is further enhanced withswitching silicon designed to support multi-layer switching, and a module slot thatsupports a single-port 10-Gigabit Ethernetmodule, with CX-4, LR, or ER XENPAK portsthat can be used to connect back to thenetwork core.Ease of UseDynamic routing with RIP (RoutingInformation Protocol) allows automaticupdating of Layer 3 network topologies.Speed and duplex mode on all ports arenegotiated automatically, preventing thepossibility for improper configuration.Switches detect and adjust to cross-over orstraight through cable connections via “AutoMDI/MDIX” feature, eliminating the needfor different cables to interconnect networkdevices.SecurityThe Switch 3870 family ensures secureaccess to resources using standard 802.1Xnetwork access control combined withRADIUS authentication. Additionally,RADIUS Authenticated Device Access(RADA) enables authentication of attacheddevices via MAC address for an additionallevel of endpoint security. Port-basedAccess Control Lists (ACLs) effectivelyenable usage policies at each point of accessto the network via the switch.Secure Shell (SSHv2), Secure Sockets Layer(SSL/HTTPs) and SNMPv3 support ensuresecure management access to switches viaauthentication and encryption of manage-ment traffic.Powerful ManagementComprehensive support within the 3Commanagement application software suite,including the standalone packages 3ComEnterprise Management Suite or 3ComNetwork Director. 3Com NetworkSupervisor may also be used in smallernetworks.Service3Com products are backed by 3Com GlobalServices and authorized partners withdemonstrated expertise in network assess-ment, implementation, and maintenance.Ask about which 3Com Network HealthCheck, installation services, and mainte-nance service packages are available in yourarea.Limited Lifetime Hardware WarrantyLimited Lifetime Hardware Replacement.See www.3com.com/warranty for details.3COM ® SWITCH 3870 10/100/1000 FAMILY DATA SHEET2Key Benefits
