1 Introduction
The S5700-LI is a next-generation energy-saving gigabit Ethernet switch that provides flexible GE access ports
and 10GE uplink ports. Building on next-generation, high-performance hardware and the Huawei Versatile
Routing Platform (VRP), the S5700-LI supports Advanced Hibernation Management (AHM), intelligent stack
(iStack), flexible Ethernet networking, and diversified security control. It provides customers with a green, easyto-manage, easy-to-expand, and cost-effective gigabit to the desktop solution. In addition, Huawei customizes
specialized models to meet customer requirements to suit special scenarios.
Huawei S5700-LI-BAT series battery LAN switches (S5700-LI-BAT for short) are the industry's first switch
series to support built-in batteries and provide visualized battery status management. The S5700-LI-BAT can
ensure uninterrupted services in environments facing frequent mains power failures at the access layer. Access
switches are usually distributed; therefore, it is costly and space-consuming to deploy high-performance
Uninterruptible Power Supplies (UPSs) for the access switches. Low-end UPSs or external lead-acid batteries can
provide power redundancy at lower costs, but have low reliability and security, short lifespan, and also occupy
significant space. Huawei battery LAN switches solve this problem. The use of internal batteries ensures stable
operation of the access layer in the event of mains power failures.
CSFP switches support downlink CSFP ports, and each downlink CSFP port provides 2 Gbit/s bandwidth
bidirectionally. CSFP switches apply to scenarios where users increase continuously and demand higher
bandwidth, and scenarios where deploying fibers is costly and difficult and construction timeframes are long.
The switches with front power sockets can be installed in the 300 mm deep cabinet.
The S5701-LI series with front power sockets can be installed in the 300 mm deep cabinet. They can be
maintained through the front panel, saving space in small equipment rooms.

4 Product Characteristics and Advantages
Innovative Energy Saving Design
The S5700-LI series smart energy-saving switches reduce power consumption without degrading system
performance or user experience. The S5700-LI series uses innovative energy-saving technologies including
energy efficient Ethernet (EEE), port power detection, dynamic CPU frequency adjustment, and device sleep
mode. These technologies help reduce power consumption by adjusting power depending on the Up/Down
states of links, presence/absence of optical modules, shutdown and undo shutdown operations on ports,
and peak and off-peak hours. The S5700-LI series is the industry's first switch series that supports device
sleep mode, and provides three energy saving modes to adapt to different usage scenarios: standard, basic,
and deep modes.
Flexible Ethernet Networking
In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple
Spanning Tree Protocol (MSTP), the S5700-LI 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 S5700-LI supports SmartLink, which implements backup of uplinks. One S5700-LI switch can connect to
multiple aggregation switches through multiple links, significantly improving reliability of access devices.
The S5700-LI supports Ethernet OAM (IEEE 802.3ah/802.1ag) to fast-detect link faults.
S5700-10P-LI supports IPv4 static routing and Layer3 hardware forwarding.
Diversified security control
The S5700-LI supports 802.1x authentication, MAC address authentication, and combined authentication on
a per port basis, as well as Portal authentication on a per VLANIF interface basis, and implements dynamic
policy delivery (VLAN, QoS, and ACL) to users.
The S5700-LI provides a series of mechanisms to defend against DoS attacks and user-targeted attacks. DoS
attacks are targeted at switches and include SYN flood, Land, Smurf, and ICMP flood attacks. User-targeted
attacks include bogus DHCP server attacks, IP/MAC address spoofing, DHCP request flood, and changing of
the DHCP CHADDR value.
The S5700-LI collects and maintains information about access users, such as IP addresses, MAC addresses, IP
address leases, VLAN IDs, and interface numbers in a DHCP snooping binding table. In this way, IP addresses
and access interfaces of DHCP users can be tracked. You can specify DHCP snooping trusted and untrusted
ports to ensure that users connect only to the authorized DHCP server.
The S5700-LI supports strict ARP learning. This feature prevents ARP spoofing attackers from exhausting ARP
entries so that users can connect to the Internet normally.

Easy operation and maintenance
The S5700-LI supports Huawei Easy Operation, a solution that provides zero-touch deployment, replacement
of faulty devices without additional configuration, USB-based deployment, batch configuration, and batch
remote upgrade. The Easy Operation solution facilitates device deployment, upgrade, service provisioning,
and other management and maintenance operations, and also greatly reduces costs of operation and
maintenance. The S5700-LI can be managed and maintained using Simple Network Management Protocol
(SNMP) V1, V2, and V3, Command Line Interface (CLI), web-based network management system, or Secure
Shell (SSH) V2.0. Additionally, it supports remote network monitoring (RMON), multiple log hosts, port traffic
statistics collection, and network quality analysis that helps with network consolidation and reconstruction.
EasyDeploy: The Commander collects information about the topology of the client connecting to the
Commander and saves client startup information based on the topology. The client can be replaced
without configuration. Configuration and scripts can be delivered to the client in batches. In addition, the
configuration delivery result can be queried.
The Commander can collect and display power consumption on the entire network.
The S5700-LI can use the GARP VLAN Registration Protocol (GVRP) to implement dynamic distribution,
registration, and propagation of VLAN attributes. GVRP reduces manual configuration workload and ensures
correct configuration. Additionally, the S5700-LI supports MUX VLAN, which involves a principal VLAN and
multiple subordinate VLANs. Subordinate VLANs are classified into group VLANs and separate VLANs. Ports
in the principal VLAN can communicate with ports in subordinate VLANs. Ports in a subordinate group VLAN
can communicate with each other, whereas ports in a subordinate separate VLAN can communicate only
with ports in the principal VLAN. The S5700-LI also supports VLAN Central Management Protocol (VCMP)
and VLAN-Based Spanning Tree (VBST) protocol.
iStack
The S5700-LI supports intelligent stack (iStack). This technology combines multiple switches into a logical
switch. 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 ports, bandwidth, and processing capacity of a stack by simply adding member switches to the
stack. 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.
Excellent network traffic analysis
The S5700-LI supports the 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.
