SWITCHINGH3C S3600OverviewH3C S3600 Series Ethernet Switches are a new generation of premiermulti-layer switches that entirely fulfill the enterprise requirement fordesign and implementation of a unified, highly resilient network. One ofthe most important and innovative highlights of the S3600 SeriesEthernet Switches is the IRF (Intelligent Resilient Framework)technology which offers the highly efficient advantage of stackabletechnology. IRF enables network managers to build adaptablenetworks with high reliability, scalability and easy management. “Pay asyou go” is the slogan of the S3600 Series Ethernet Switches.H3C S3600 Series Ethernet Switches include the following models:S3600-28P-SI, S3600-28TP-SI, S3600-28P-EI, S3600-28F-EI,S3600-28P-PWR-EI, S3600-28P-PWR-SI, S3600-52P-SI,S3600-52P-EI, S3600-52P-PWR-SI and S3600-52P-PWR-EI.FeaturesFull wire-speed, multi-layer switchingu The S3600 Series offer L2/L3 wire-speed switching capability forall ports. The system offers 4 GE ports to meet the requirement ofa single piece of equipment for multiple Gigabit uplinks and foraccess to the Gigabit server, thereby greatly increasing savingson equipment investment.u The hardware supports L3 wire-speed switching, and is able toidentify and process the application traffic flows from L2~L4.u All ports have an independent data packet filter, and distinguishspecific application flows for different management and control.IRF TechnologyIntelligent Resilient Framework (IRF) is an innovative resilient networktechnology that allows enterprise customers to design and implementFast Ethernet core and aggregation that are adaptable, providingexceptional reliability, scalability and easy management. With IRFtechnology, the S3600 Series switches can be interconnected togetherto behave as a single logical switching entity called a Distributed Fabric.From management and configuration perspectives, the Fabric appearsas a single device, while from a performance perspective, each switchin the Distributed Fabric can make its own forwarding decisions, both atLayer 2 and Layer 3 for traffic that appears on its ports.The IRF technology provides: DDM (Distributed Device Management),DRR (Distributed Resilient Routing) and DLA (Distributed LinkAggregation).u Distributed Device Management (DDM)Distributed Device Management is the control system for IRFtechnology, responsible for distributing management and controlinformation across the IRF Distributed Fabric.u Distributed Resilient Routing (DRR)Distributed Resilient Routing, provided by Enhanced Image, is anadvanced routing implementation that allows multipleinterconnected switches in an IRF Distributed Fabric to behave asa single active routing entity.u Distributed Link Aggregation (DLA)Distributed Link Aggregation, provided by Enhanced Image,allows networks and IRF Distributed Fabrics to be coordinated
