S5750E-26 X-SI provides 24 10GbE (SFP+) and 2 40GbE(QSFP) physical ports and redundant power supplies, designed for data center 10G server high-density access scenario and general network 10G convergence scenario relied on telecom grade design features of high reliability, redundancy, high density. It can provide high-performance, easy management and low-cost solutions for data center networks and general networks based on dual link redundancy backup,advanced green environmental protection technology and high bandwidth up to 40G.Main FeaturesPerformance and Scalability The 10 Gigabit Ethernet connectivity of S5750E-26X-SI is accomplished via a hot-pluggable 10 Gigabit SFP+ transceiver which supports distance up to 300 meters over multimode fiber and 10 to 40km over single-mode fiber (The distance depends the optical module chosen). S5750E-26X-SI supports built-in redundant AC and DC power supplies for different environment applications.Full Optical PortS5750E-26X-SI supports abundant optical connection ports to construct full optical network and increases the performance of networks.Easy high reliability networkS5750E-26X-SI supports 24 10GbE (SFP+) and 2 40GbE(QSFP) as uplink ports, which could be designed to offer redundant uplinks with various ring protection applications, effectively raised the expansibility and performance of network.Virtual Switch framework (VSF) could virtualized multiple DCN switches into one logical device, achieves the sharing of information and data tables between different switches. The performance and ports density of virtualized device are greatly enlarged by times under VSF. VSF also provides simplified management work for network administrator and more reliability.G.8032 provides sub-50ms protection and recovery switching forEthernettraffic in a carrierring topology. S5750E-26X-SI supports G.8032 v2 and can be deployed in a variety of complex network topologies including single ring, tangent ring, intersecting rings, double rings and other home networking.Multi-process MSTP. When a new access ring can be implemented through creating a new process of MSTP, the new ring does not affect the existing traffic. And each process may run different spanning tree protocol.DCN EMVTE technology (Enhanced Multi-VLAN subnet Traffic Engineering) is a multi-link backup and load balancing solution based on multiple VLAN subnets for dual homing network. It can achieve faster switching and convergence of the uplink through ULPP (Uplink Protection Protocol) and ULSM (Uplink State Monitor) protocol so that network performance is guaranteed.Comprehensive QoSWith 8 queues per port, S5750E-26X-SI enables differentiated management of up to 8 traffic types. The traffic is prioritized according to IEEE802.1p, DSCP, IP precedence and TCP/UDP port number, giving optimal performance to real-time applications such as voice and video. S5750E-26X-SI also supports Bi-directional rate-limiting, per port or traffic class, preserves network bandwidth and allows full control of network resources. Enhanced SecurityS5750E-26X-SI provides a variety of security mechanisms like SYN Flood, Land, ICMP Flood attack prevention and other DOS class technology, BPDU Guard and Root Guard which avoid accidental topology loops and prevent illegal edge devices become root to cause unnecessary flapping.IEEE 802.1X port-based access control ensures all users are authorized before being granted access to the network. User authentication is carried out using any standard-based RADIUS server. Ingress/Egress Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets based on L2/L3/L4 headers information. And for some services are based on time, the product can support time based ACL to match the requirement.S5750E-26X-SI support DHCP snooping, which prevents DHCP attacks and illegal DHCP SERVER by setting trust ports and untrust ports. With DHCP Snooping binding and option82 enabled, it can combine modules like dot1x and ARP, or implement user-access-control independently.S5750E-26X-SI supports much more L2 security features such as ARP guard, Anti-ARP scanning, and other ARP and MAC Security technology to protect network security and reliability. Secure Shell (SSH) encrypts network management information via Telnet providing secure network management. RADIUS/TACACS Authentication enables centralized control of the switch and restricts unauthorized users from altering the configuration of the switch.Simple and Flexible Operation and MaintenanceFull Ethernet OAM technology (IEEE802.3ah/802.1ag), VCT, DDM (Digital Diagnostic Monitoring) and other features achieve rapid detection of the network failures; reduce operation and maintenance difficulty.ERSPAN (Encapsulated Remote Switched Port Analyzer) technology mirrors traffic through the GRE tunnel technology which simplifies the configuration, helps network administrators to manage remote devices conveniently.High adaptability VLAN FeaturesS5750E-26X-SI supports 802.1Q and port based VLAN as well as MAC based VLAN, Voice VLAN and Protocol VLAN. Abundant QinQ technology including Normal QinQ and Flexible QinQ, gives users maximum freedom to configure QinQ policy.N:1 VLAN Translation feature can translate multiple VLAN tags in the frames from access ports into one specified VLAN Tag. It provides a strong technical support for QoS policy convergence.Abundant Multicast FeaturesS5750E-26X-SI also supports MVR (Multicast VLAN Register), selectively allows traffic to cross between different VLANs for bandwidth and security reasons. With MVR Trunk function, which could associate multicast VLAN to trunk port, S5750E-26X-SI combines the VLAN data into the same link, saving lots of resources for users.S5750E-26X-SI could prevent multicast traffic from flooding via IGMP Snooping, while multicast traffic is only forwarded to ports associated to multicast devices.Green EnergyWith Innovative port-LED Shut-off function, the user can automatically set the switch port-LED UP or DOWN at a specified time period according to their needs to achieve functional, energy-saving correct results.Full account of low noise requirements of the environment, S5750E-28X-SI use Smart Fan strategies to control fan speed according to real-time temperature monitoring system which can effectively reduce speed, extend fan life and reduce noise pollution.SpecificationsItemS5750E-26X-SIManagement Port1 Console portPorts24x10GbE (SFP+) + 2x40GbE(QSFP)(each 40GbE(QSFP) can be divided 4 10GbE (SFP+))PerformanceSwitching Capacity640GbpsForwarding Rate480MppsMAC ADDRESS32KJumbo frame12KACL Table3K (ingress) + 1K (egress)Queues per port8VLAN TABLE4KPhysical Dimension(W×H×D)440mm x 43.6mm x 318mmPower InputAC: 100~240VAC, 50~60HzDC: Input -60V ~ -40VPower Consumption<70WTemperatureWorking 0°C~50°C, Storage -40°C~70°CRelative Humidity10%~90%,non-condensingEMC safetyCE, RoHSMain FeaturesForwardingStorage and ForwardingVLANPort-based VLANIEEE802.1Qprivate VLANProtocol VLANVoice VLANMAC VLANNormal QinQ, Flexible QinQVLAN TranslationDHCPIPv4/IPv6 DHCP Client,IPv4/IPv6 DHCP RelayOption 82IPv4/IPv6 DHCP Snooping,IPv4/IPv6 DHCP ServerReliabilitySpanning Tree802.1D STP, 802.1W RSTP, 802.1S MSTPRoot Guard, BPDU Guard, BPDU ForwardingMulti-Process MSTPLACP128 groups per device/8 ports per groupLoad balanceL2 Ring ProtectionMRPPITU-T G.8032Loopback DetectionFast linkMulti-link Backup Enhanced Multi-VLAN subnet Traffic Engineering (ULPP+ULSM)VSFVirtual Switch frameworkSecurityIP ACL, MAC ACL, MAC-IP ACL, User-Defined ACLTime Range ACLVLAN ACLStorm Control based on packets and bytesPort Security, MAC Limit based on VLAN and PortAnti-ARP-Spoofing , Anti-ARP-Scan, ARP BindingND SnoopingDAIIEEE 802.1xAuthentication, Authorization, AccountingRadius, TACACS+MulticastIGMP v1/v2/v3 snooping, IGMP Fast leave MVRMLD v1/v2 snoopingIPv4/IPv6 DCSCM(D)QoS8 Queues Per PortBandwidth ControlFlow RedirectClassification based on ACL, VLAN ID, COS, TOS, DSCP, IPv6 Flow LabelPolicing based on Port and VLANSingle Rate Three Colors, Dual Rates Three Colors for PolicingRemark DSCP, COS/802.1p, Precedence, TOSSP, WRR, SWRR, WDRR for SchedulingMaintenance and Operation ManagementXModem/TFTP/FTPCLI, Telnet, ConsoleWeb/SSL (IPv4/IPv6)SSH (IPv4/IPv6)SNMPv1/v2c/v3SNMP TrapPublic & Private MIB interfaceRMON 1,2,3,9Ping, Trace RouteRadius AuthenticationSyslog (IPv4/IPv6)SNTP/NTP (IPv4/IPv6)Dual IMG, Multiple Configuration FilesPort Mirror, CPU Mirror, RSPANsFlowOAM EFM; OAM CFMDying GASPDDMULDP(like Cisco UDLD)LLDP/LLDP MEDGreen EnergyAuto Fan Speed Control, Temperature AlarmLED Shut-off
