The S6720-SI provides two power slots, by default, one AC or DC power supply is equipped. When a switch has two power supplies installed, the power supplies work in 1+1 backup mode to power the switch itself. Product Characteristics and Advantages Huawei S6720-SI series switches have the following characteristics. High-Density Multigigabit Access and 40 Gbit/s Uplink 3 • As the 802.11ac standard and related products are released, the wireless access rate has reached 2.5 Gbit/s. The S6720-SI multigigabit ﬁxed switches match perfectly with high-speed APs, and provide the long distance PoE++ function and 60 W PoE on a port. The S6720-SI can provide Ethernet power supply for APs and surveillance cameras. • The S6720-SI ﬁxed switch has the highest density of multigigabit ports and largest switching capacity among counterpart switches. Each S6720-SI provides up to two line-rate QSFP+ ports and 24 100M/1G/2.5G/5G/10G Base-T ports. • Ports of the S6720-SI support 100M/1G/2.5G/5G/10G Base-T access and auto-sensing, maximizing the return on investment (ROI) and allowing users to ﬂexibly deploy services. Huawei Enterprise Sx700 Series Switch Product Comprehensive Security Policies • The S6720-SI provides multiple security measures to defend against Denial of Service (DoS) attacks and other attacks to networks or users. DoS attacks include SYN ﬂood, Land, Smurf, and ICMP ﬂood attacks. Attacks to networks refer to STP BPDU/root attacks. Attacks to users include bogus DHCP server attacks, man-in-the-middle attacks, IP/MAC spooﬁng attacks, DHCP request ﬂood attacks, and DoS attacks by changing the CHADDR ﬁeld of packets. • The S6720-SI supports DHCP snooping, which generates user binding entries. DHCP snooping discards invalid packets that do not match any binding entries, such as ARP spooﬁng packets and IP spooﬁng packets. This prevents hackers from using ARP packets to initiate man-in-the-middle attacks on campus networks. DHCP snooping trusted and untrusted ports can be speciﬁed to ensure that users connect only to the authorized DHCP server. • The S6720-SI supports strict ARP learning. This feature prevents ARP spooﬁng attackers from exhausting ARP entries so that users can connect to the Internet normally. It also provides IP source check to prevent DoS attacks caused by MAC address spooﬁng, IP address spooﬁng, and MAC/IP spooﬁng. URPF provided by the S6720-SI reversely checks packet transmission path to authenticate packets, which can protect the network against source address spooﬁng attacks. • The S6720-SI supports centralized MAC address authentication and 802.1X authentication. It authenticates users based on statically or dynamically bound user information such as the user name, IP address, MAC address, VLAN ID, port number, and ﬂag indicating whether antivirus software is installed. VLANs, QoS policies, and ACLs can be delivered to users dynamically. • The S6720-SI can limit the number of MAC addresses learned on a port to prevent MAC address entries from being exhausted by source MAC address spooﬁng packets. This function minimizes packet ﬂooding that occurs when MAC addresses of users cannot be found in the MAC address table. Comprehensive Reliability Mechanisms • The S6720-SI supports redundant power supplies. Users can choose a single power supply or use two power supplies to ensure device reliability. With two pluggable fan modules, the S6720-SI has a longer MTBF time than counterpart switches. • The S6720-SI supports MSTP multi-process that enhances the existing STP, RSTP, and MSTP implementation. This function increases the number of MSTIs supported on a network. It also supports enhanced Ethernet reliability technologies such as Smart Link and RRPP, which implement millisecondlevel link protection switchover and ensure network reliability. Smart Link and RRPP both support multiinstance to implement load balancing among links, further improving bandwidth usage. • The S6720-SI supports enhanced trunk (E-trunk). A CE can be dual-homed to two PEs through EthTrunk links. This implements inter-device link aggregation and link load balancing, and greatly improves reliability of access devices. • The S6720-SI supports the Smart Ethernet Protection (SEP) protocol, a ring network protocol applied to the link layer of an Ethernet network. SEP can be used on open ring networks and provides millisecondlevel switchover to ensure uninterrupted services. This protocol is simple, reliable, easy to maintain, and supports fast switchover and ﬂexible topology, enabling users to manage and plan networks conveniently. • The S6720-SI supports G.8032, also called Ethernet Ring Protection Switching (ERPS). ERPS is based on traditional Ethernet MAC and bridging functions. It uses the mature Ethernet OAM and Ring Automatic Protection Switching (Ring APS or R-APS) technologies to implement millisecond-level protection switching on Ethernet. ERPS supports multiple services and provides ﬂexible networking, reducing the OPEX and CAPEX. • The S6720-SI supports VRRP. Two S6720-SI switches can form a VRRP group to ensure nonstop and reliable communication. Multiple equal-cost routes to an upstream device can be conﬁgured on the S6720-SI to provide route redundancy. When an active route is unreachable, trafﬁc is switched to a backup route. Huawei Enterprise Sx700 Series Switch Product 4 Various QoS Control Mechanisms • The S6720-SI implements complex trafﬁc classiﬁcation based on packet information such as the 5-tuple, IP precedence, ToS, DSCP, IP protocol type, ICMP type, TCP source port, VLAN ID, Ethernet protocol type, and CoS. ACLs can be applied to inbound or outbound direction to ﬁlter packets. The S6720-SI supports the ﬂow-based two-rate and three-color CAR. Each port supports eight priority queues and multiple queue scheduling algorithms such as WRR, DRR, PQ, WRR+PQ, and DRR+PQ, which ensures the quality of network services such as voice, video and data services. High Scalability • The S6720-SI supports iStack and virtualizes multiple switches into one logical switch. A port of the S6720-SI can be conﬁgured as a stack port using a command for ﬂexible stack deployment. The distance between stacked switches is further increased when the switches are connected with optical ﬁbers. Compared with a single device, iStack features powerful scalability, reliability, performance, and architecture. New member switches can join a stack to increase the system capacity or replace a faulty member switch without interrupting services. Compared with stacking of modular switches, the iStack function can increase system capacity and port density with no restriction of the hardware structure. Multiple devices in a stack can be considered as one logical device. These switches can be managed using a single IP address, which greatly reduces costs for system expansion and O&M. Convenient Management • The S6720-SI supports automatic conﬁguration, plug-and-play, deployment using a USB ﬂash drive, and batch remote upgrade. These capabilities facilitate deployment, upgrade, and service provisioning, and simplify device management and maintenance. The maintenance costs are greatly reduced. • The S6720-SI supports SNMPv1/v2/v3 and provides ﬂexible methods for managing devices. Users can manage the S6720-SI using the CLI and Web NMS. The NQA function helps users with network planning and upgrades. In addition, the S6720-SI supports NTP, SSH v2, HWTACACS, RMON, log hosts, and portbased trafﬁc statistics. • The S6720-SI supports GVRP, which dynamically distributes, registers, and propagates VLAN attributes to reduce the manual conﬁguration workloads of network administrators and ensure correct VLAN conﬁguration. • The S6720-SI supports MUX VLAN, a mechanism that isolates Layer 2 trafﬁc between ports in a VLAN. MUX VLAN deﬁnes principal VLANs and subordinate VLANs. Subordinate VLANs can communicate with the MUX VLAN but cannot communicate with each other. This function prevents communication between network devices connected to certain ports or port groups but allows the devices to communicate with the default gateway. MUX VLAN is usually used on an enterprise intranet to isolate user ports from each other but allow them to communicate with server ports. • The S6720-SI supports BFD, which provides millisecond-level fault detection for protocols such as OSPF, IS-IS, VRRP, and PIM to improve network reliability. The S6720-SI supports IEEE 802.1ag and IEEE 802.3ah. 802.1ag allows for point-to-point Ethernet fault management, and IEEE 802.3ah can detect faults in the last mile of an Ethernet link. Ethernet OAM improves the Ethernet network management and maintenance capabilities and ensures a stable network. Various IPv6 Features 5 • The S6720-SI supports IPv4/IPv6 dual stack and can migrate from an IPv4 network to an IPv6 network. The S6720-SI hardware supports IPv4/IPv6 dual stack and IPv6 over IPv4 tunnels (including manual tunnels, 6to4 tunnels, and ISATAP tunnels). The S6720-SI can be deployed on IPv4 networks, IPv6 networks, or networks that run both IPv4 and IPv6. This makes networking ﬂexible and enables a network to migrate from IPv4 to IPv6. • The S6720-SI supports various IPv6 routing protocols including RIPng and OSPFv3. The S6720-SI supports the Neighbor Discovery Protocol (NDP) of IPv6, and manages packets exchanged between neighbors.

It refers to the maximum volume of bidirectional trafﬁc that can be transferred between the switching chip and data bus. This index indicates the data transferring capability of a switch. • Forwarding performance: This index indicates the wire-speed forwarding capability of a switch when the switch processes 64-byte packets (plus an 8-byte preamble and a 12-byte IFG). It represents the packet header processing capability. Huawei Enterprise Sx700 Series Switch Product Networking and Applications Data Center Network As shown in the following ﬁgure, the S12700 agile switches function as core switches in a data center and use ﬁrewall and load balancer cards to ensure security and perform load balancing. The S6720-SIs function as access switches and provide high-density 10GE ports to connect to 10G servers. Small and Middle Campus Network The S6720-SI series switches can be used as access or aggregation switches on small- and medium-sized campus networks and provide 2.5G ports for high-speed AP access, meeting the requirement for increasing bandwidth. The rich service features and comprehensive security mechanisms make the S6720-SI cost effective on campus networks. Huawei Enterprise Sx700 Series Switch Product 12 Product Accessories Optical Modules and Fibers The S6720-SI supports the following GE ,10GE and 40GE optical modules: • GE: 100 m electrical, 500 m optical multi-mode, 10/40/80/100 km optical single-mode, two pairs of bidirectional optical modules (10/40 km) • 10GE: 100/220/300 m SFP+ multi-mode, 1.4/10/40/80 km optical SFP+ • 40GE:150/400 m QSFP+ optical multi-mode, 1.4/2/10/40 km optical single-mode Optical fibers fall into single-mode and multimode fibers. Single-mode optical modules use single-mode ﬁbers, and multi-mode optical modules use multi-mode ﬁbers. For a non-BIDI optical module, each optical interface must be conﬁgured with a Tx optical ﬁber and an Rx optical ﬁber of the same type. For a BIDI optical module, only one optical ﬁber needs to be conﬁgured. The ﬁbers and optical modules supported by Huawei switches are updating. For the latest information, visit http://enterprise.huawei.com or contact your local Huawei sales ofﬁce. Stack Cables The S6720-SI switches support service port stacking. The applicable stack cables are as follows: 13 • AOC cable • An active optical network (AOC) cable integrates an optical module and ﬁber.
