SWITCHING H3C S5120-SI Intelligent GE Switch Overview The H3C S5120-SI series switches are Layer 2 intelligent manageable switches designed for networks where high performance, high-density port access and easy installation are required. The S5120-SI series switches are mainly deployed at the access layer in enterprise Protocol/Rapid Spanning Tree Protocol/Multiple Spanning Tree Protocol). The STP/RSTP features also support BPDU guard and Root guard. Thus the redundancy back-up and error tolerance capability of the link can be greatly improved to guarantee network stability. networks that require Gigabit to the Desktop (GTTD) and at the S5120-SI series switches support link-aggregation (including manual distribution layer in metropolitan-area networks (MANs). link aggregation and LACP), providing a simple and cost efficient way The H3C S5120-SI series switches include the following models: S5120-9P-SI, S5120-20P-SI, S5120-28P-SI, S5120-52P-SI, S51209P-PWRSI, S5120-9P-HPWR-SI, S5120-28P-PWR-SI and S512028P-HPWR-SI. Features Full wire-speed, multi-layer switching S5120-SI series switches offer L2 wire-speed switching capacity. The product series offers high density, wire speed, GE ports and satisfies the most demanding requirements. S5120-SI series switches are able to expand the bandwidth of a switch port and balance the traffic among all the ports in a link aggregation. This also enhances connection reliability. Comprehensive security control policies S5120-SI series switches support 802.1x authentication to identify users who attempt to access the network. With the 802.1x client version checking function enabled, the switch checks the version and validity of the 802.1x client running on supplicant systems to prevent those that use earlier versions of the 802.1x client or illegal clients from logging in. to identify and process traffic flows from L2-L4. With independent S5120-SI series switches provide Guest VLAN functions so that packet filters, all ports distinguish different flows and forward them with authorized terminals can only access specified resources and attain corresponding priority. corresponding policies. For example, they can obtain 802.1x clients, High reliability upgrade clients, or attain other upgrade programs. S5120-SI series switches support STP/RSTP/MSTP (Spanning Tree They support Secure Shell V2 (SSH V2) to guarantee information 2 SWITCHING security and powerful authentication, thus preventing Ethernet S5120-SI series switches support Loopback detection on ports. After switches from attacks, such as IP address spoofing and interception of users enable loopback detection for Ethernet ports, the switch will plain text passwords. monitor whether the ports have loopback on a regular basis; if the Diversified QoS policies switch detects loopback for a particular port, t will bring that port back under control. S5120-SI series switches support packet filtering at L2 to L4 and traffic classification based on source MAC addresses, destination MAC S5120-SI series switches support VCT (Virtual Cable Test) which is addresses, source IP addresses, destination IP addresses, TCP/UDP convenient for troubleshooting. Customers can start the virtual cable port numbers, protocol types and VLANs. H3C S5120-SI series test (VCT) to have the system test the cable connected to the current switches support flexible queue scheduling including SP, SDWRR and electrical Ethernet port. The test items include: whether a short or SP+SDWRR. They support port rate limiting with a minimum open circuit exists in the Rx/Tx direction of the cable, and what is the granularity of up to 64 kbps. They also support port mirroring at both length of the cable in normal status or the length from the port to the the egress and ingress directions. fault point of the cable. Excellent manageability POE/POE+ S5120-SI series switches support Simple Network Management Protocol (SNMP) v1/v2/v3, Open View, iMC, CLI, Web-based NMS, Telnet, and HGMPv2 so that devices are conveniently managed. They S5120-SI series switches provide POE+ function with maximum output 30W power per port which can be used for 802.11n access point, IP video phone and other terminal devices. also support SSH2.0 to provide better protection management.
