Quidway® S3900 Series Switches
The Quidway® S3900 Series Ethernet Switches are a new line of premier multilayer switches that entirely fulfills the enterprise customer’s requirement of designing and implementing a unified, highly resilient network. One of the most important and innovative highlight of S3900 Series Ethernet Switches is the IRF technology (Intelligent Resilient Framework) which represents the most advantage stackable technology. IRF technology, which is a completely innovative technology, allows network managers to build affordable networks with high resilient, flexibility and exceptional performance.With flexible software options, the Quidway® S3900 Series switch is available in the Standard Software Image (SI) and the Enhanced Software Image (EI), offering a cost-effective path for meeting current and future service requirements from enterprises and commercial businesses. The SI feature set includes advanced quality of service (QoS), rate-limiting, access control lists (ACLs), static and Routing Information Protocol (RIP) routing, and basic IRF function. In addition to these features, the EI feature set provides a richer set of enterprise-class features such as advanced hardware-based IP unicast, multicast routing, and advanced IRF functionality.
Product Specifications
IRF Technology
Intelligent Resilient Framework (IRF) is an innovative resilient network technology that allows enterprise customers to design and implement high availability Fast Ethernet core and aggregation backbones that are affordable and provide exceptional performance, scalability and availability. With IRF technology, the Quidway® S3900 Series switches can be interconnected together to behave as a single logical switching entity called a Distributed Fabric. From management and configuration perspective, the Fabric appears as a single device; while from a performance perspective, each switch in the Distributed Fabric can make its own forwarding decisions, both a Layer 2 and Layer 3 for traffic that
appears on its ports.
Distributed Device Management (DDM)
Distributed Device Management is the control system of IRF technology, responsible for distributing management and control information across the IRF Distributed Fabric. DDM allows the entire IRF Distributed Fabric to be managed as a single logical entity. Management tasks are all performed across the Distributed Fabric, minimizing complexity and administration overheads. In addition, the management IP address is shared across all units in the IRF Distributed fabric, ensuring continuous device management and monitoring, in the event of an outage in one of the interconnected switches.
Distributed Resilient Routing (DRR)
Distributed Resilient Routing, provided by Enhanced Image, is an advanced routing implementation that allows multiple interconnected switches in an IRF Distributed Fabric to behave as a single active routing entity. Unlike resilient Layer 3 implementations such as VRRP and HSRP, DRR intelligently distributes the routing load across all switches in the Distributed Fabric to optimize routing performance and make full use of bandwidth capacity.
Distributed Link Aggregation (DLA)
Distributed Link Aggregation, provided by Enhanced Image, allows networks and IRF Distributed Fabrics to be coordinated with switches at edge of the network. With the ability to multi-home across different units in the IRF Distributed Fabric, the availability of the entire network is dramatically increased. Traffic is forwarded across all links in the Aggregated Link to the fabric to optimize the use of available capacity. DLA guarantees high levels of resiliency since failure in one of the members of the Aggregated Link results in automatic redistribution of traffic across the remaining links.
Excellent PoE (Power over Ethernet) Supply Function
The Quidway® S3900 series switches support PoE function for the LAN switching infrastructure, which provides power over a copper Ethernet cable to an endpoint (Powered Device). With the Quidway® S3900, up to 15.4W/port of power on every 10/100 port ensures maximum device support for IP telephony and wireless LAN deployments. As PSE (Power Sourcing Equipment) devices, the Quidway® S3900 series are 802.3af compliant PoE switches. With PoE and Voice VLAN technology, the Quidway® S3900 series switches can supply a perfect solution for a converged voice and data network.
Full Wire-speed, Multi-layer Switching
The Quidway® S3900 series offer L2/L3 wire-speed switching capability for all ports of the switch. The system offers 4 GE to meet one piece of equipment’s requirement for multiple Gigabit uplinks and for access to the Gigabit server, thus greatly saving the equipment investment. The Hardware supports L3 wire-speed switching, and is able to identify and process the application traffic flows from L2~L7. All ports have an independent data packet filter, and distinguish different application flows for different management and control.
Flexible Security Control Policies
Based on the longest match routing policy, Quidway® S3900 series forward the packets one by one so that the packets acquire the same forwarding performance. This function can guard the network against the attack by Code Red and Worm Blaster, thus guaranteeing the equipment security. The Quidway® S3900 series support 802.1x authentication to identify users who attempt to access the network. They can also prevent unauthorized access to the network by binding any combination of MAC, IP, VLAN and PORT.
Secure Shell (SSH) offers security information protection and powerful authentication function to safeguard the Ethernet switch from attacks such as IP address spoofing and plain text cipher interception.
High Reliability
The Quidway® S3900 series support STP/RSTP and multi-VLAN based MSTP, thus greatly improving the redundant backup for links and the fault tolerance capability, so that the network can run stably.
The Quidway® S3900 series support the optional RPS (Redundant Power Supply, provided by Enhanced Image) and can provide power redundancy for four pieces of equipments, thus improving the fault tolerance capability and normal network operation duration.
The Quidway® S3900 series support VRRP (provided by Enhanced Image), and can build a VRRP backup group with other L3 switches. They can build a redundant route topological structure when a fault occurs to guarantee communication continuity and reliability, keeping network stable status.
The Quidway® S3900 series implement redundant backup routes by configuring multiple equivalent routes. When the active uplink route becomes faulty, it will automatically switch to the next backup router, thus achieving multi-level backup for uplink routes.
Abundant QoS Policies
The Quidway® S3900 series support L2~L7 complex flow classification based on source MAC address/destination MAC address/source IP address/destination IP address/ ports/protocols.
The Quidway® S3900 series support flexible queue scheduling algorithms, which can be set on the basis of port and queue at the same time. They support Strict Priority (SP), Weighted Round Robin (WRR), Weighted Fair Queuing (WFQ), SP+WRR, and SP+WFQ; 8 priority queues and 2 discarding priorities; WRED congestion avoidance algorithm and
port traffic shaping.
The Quidway® S3900 series support Committed Access Rate (CAR), and limit the traffic speed in the 64Kbit/s granularity.
Diversified Management Modes
The Quidway® S3900 series support Simple Network Management Protocol (SNMP) and can be managed by general network management platform such as Open View, and the Quidview® network management system. In addition, Command Line Interface (CLI), Web network management, TELNET, and HGMP cluster management make the equipment management more convenient.
