1 Introduction

Huawei S5700 series Ethernet switches (S5700 for short) are next-generation energy-saving Gigabit Ethernet switches that function as the access devices to deliver high bandwidth or aggregation device for Ethernet multi-service networks. Built on next-generation high-performance processors and Huawei Versatile Routing Platform (VRP), the S5700 is available in four series: LI, SI, EI, and HI. The S5720-SI series switches (S5720-SI for short) are next-generation standard gigabit Layer 3 Ethernet

switches that provide ﬂexible full gigabit access and cost-effective ﬁxed GE ports and 10GE uplink ports.

The S5720-SI was developed based on next-generation high-performing hardware and the Huawei

Versatile Routing Platform (VRP). The S5720-SI supports simpliﬁed operations and maintenance (O&M), intelligent stack (iStack), ﬂexible Ethernet networking, and MACsec. It also provides enhanced Layer 3

features and mature IPv6 features. The S5720-SI can be used in various scenarios. For example, it can be used as an access or aggregation switch on a campus network or as an access switch in a data center.

Single-Power

The single-power model uses a built-in AC power supply and supports RPS1800. The single-power models

include S5720S-28P-SI-AC, S5720S-28X-SI-AC, S5720S-52P-SI-AC, and S5720S-52X-SI-AC.

An RPS1800 is a redundant power supply system that provides power redundancy for the connected

switches to ensure uninterrupted services. When the internal power supply of a switch fails, the RPS1800

provides power to the switch immediately, which improves system reliability. Figure 3-2 shows how to

connect an RPS1800 to a switch.

Figure 3-2 Connecting an RPS1800 to an S5720S-S

The RPS1800 provides 1+6 cold backup for the switch:

• The RPS1800 can connect to a maximum of six switches and ensures seamless failover for at most one

switch when the internal power supply of the switch fails.

• When the internal power supply of the switch powered by the RPS1800 recovers, the RPS1800

immediately restores to backup state.

• Among the 6 DC output ports, OUT1 has the highest priority, and the other 5 ports have the same priority. When the RPS1800 connects to six switches, the switch connected to OUT1 preferentially receives power from the RPS1800.

4 Product Characteristics and Advantages

Huawei S5720-SI series have the following characteristics.

Powerful service processing capability and multiple security control mechanisms

• The S5720-SI supports many Layer 2/Layer 3 multicast protocols such as PIM SM, PIM DM, PIM SSM, MLD, and IGMP snooping, to support multi-terminal high-deﬁnition video surveillance and video conferencing

services.

• The S5720-SI supports multiple Layer 3 features including OSPF, IS-IS, BGP, and VRRP, meeting enterprises'

requirements on access and aggregation service bearing, and enabling a variety of voice, video, and data applications.

• The S5720-SI supports MAC address authentication, 802.1x authentication, and Portal authentication, and implements dynamic delivery of policies (VLAN, QoS, and ACL) to users.

• The S5720-SI provides a series of mechanisms to defend against DoS and user-targeted attacks. DoS attacks are targeted at switches and include SYN ﬂood, Land, Smurf, and ICMP ﬂood attacks. Usertargeted attacks include bogus DHCP server attacks, IP/MAC address spooﬁng, DHCP request ﬂood, and change of the DHCP CHADDR value.

• The S5720-SI sets up and maintains a DHCP snooping binding table, and discards the packets that do not match the table entries. You can specify DHCP snooping trusted and untrusted ports to ensure that users connect only to the authorized DHCP server.

• The S5720-SI supports strict ARP learning, which protects a network against ARP spooﬁng attacks to

ensure normal network access.

Easy O&M

• The S5720-SI supports Super Virtual Fabric (SVF), which virtualizes the "Core/aggregation + Access switch + AP" structure into a logical device. The S5720-SI provides the simplest network management solution in the industry to simplify device management. It allows plug-and-play access switches and APs. In addition, the S5720-SI supports service conﬁguration templates. The templates are conﬁgured on core devices and automatically delivered to access devices, enabling centralized control, simpliﬁed service conﬁguration, and ﬂexible conﬁguration modiﬁcation. The S5720-SI functions as a client in an SVF system.

• The S5720-SI supports zero-touch deployment, replacement of faulty devices without additional conﬁguration, USB-based deployment, batch conﬁguration, and batch remote upgrade. The capabilities

facilitate device deployment, upgrade, service provisioning, and other management and maintenance

operations, and also greatly reduce O&M costs. The S5720-SI can be managed using SNMP v1/v2c/v3, CLI, web-based network management system, or SSH v2.0. Additionally, it supports RMON, multiple log hosts, port trafﬁc statistics collection, and network quality analysis, which facilitate network optimization and

reconstruction.

• The S5720-SI supports the Sampled Flow (sFlow) function. It uses a method deﬁned in the sFlow standard to sample trafﬁc passing through it and sends sampled trafﬁc to the collector in real time. The collected trafﬁc statistics are used to generate statistical reports, helping enterprises maintain their networks.

Multiple reliability mechanisms

• The S5720-SI supports iStack. This technology can virtualize up to nine physical switches into one logical switch. Downlink electrical ports support iStack. Member switches in a stack implement redundancy

backup to improve device reliability and use inter-device link aggregation to improve link reliability. iStack

provides high network scalability. You can increase a stack's ports, bandwidth, and processing capacity by simply adding member switches. iStack also simpliﬁes device conﬁguration and management. After a stack

is set up, multiple physical switches are virtualized into one logical device. You can log in to any member switch in the stack to manage all the member switches in the stack.

• The S5720-SI is equipped with two removable power modules that can work in 1+1 redundancy backup mode. Mixed installation of AC and DC power modules is supported, allowing for ﬂexible conﬁguration of AC or DC power modules according to service requirements.

• In addition to traditional STP, RSTP, and MSTP, the S5720-SI supports Huawei-developed Smart Ethernet

Protection (SEP) technology and the latest Ethernet Ring Protection Switching (ERPS) standard. SEP is a

ring protection protocol speciﬁc to the Ethernet link layer, and applies to various ring network topologies,

such as open ring topology, closed ring topology, and cascading ring topology. This protocol is reliable,

easy to maintain, and implements fast protection switching within 50 ms. ERPS is deﬁned in ITU-T G.8032. It implements millisecond-level protection switching based on traditional Ethernet MAC and bridging

functions.

• The S5720-SI supports Smart Link. One S5720-SI switch can connect to multiple aggregation switches through multiple links, implementing backup of uplinks and signiﬁcantly improving reliability of access

devices.

• The S5720-SI supports Ethernet OAM (IEEE 802.3ah/802.1ag) to detect link faults quickly.

Mature IPv6 technologies

• The S5720-SI uses the mature, stable VRP platform and supports IPv4/IPv6 dual stack, IPv6 RIPng, and IPv6 over IPv4 tunnels (including manual, 6-to-4, and ISATAP tunnels). With these IPv6 features, the S5720SI can be deployed on a pure IPv4 network, a pure IPv6 network, or a shared IPv4/IPv6 network, helping

achieve IPv4-to-IPv6 transition.

PoE++ ultra-large power supply

• The S5720-SI provides a PoE++ model, which supports 2.5GE/GE PoE++ Ethernet electrical ports that are compatible with GE cables. The PoE++ model provides up to 90 W power supply per port, accommodating the requirements of scenarios in which a large power supply is required, such as enterprise ofﬁce desktop systems, smart lighting, and Wi-Fi/LTE Pico co-site.

Cloud-based management

• The S5720-SI can work in cloud-based management mode or traditional management based on

requirements. In cloud-based management mode, the S5720-SI can be monitored, managed, and

conﬁgured on the Huawei agile cloud management platform (Agile Controller-Cloud Manager). A mobile O&M app is also supported.
