S5700S-LI Series Gigabit Enterprise Switches

S5700S-LI Series Gigabit Enterprise Switches

Product Overview

The S5700S-LI series gigabit enterprise switches (S5700S-LI for short) are next-generation energy-saving

switches developed by Huawei to meet the demand for high-bandwidth access and Ethernet multi-service

aggregation. Based on the cutting-edge hardware and Huawei Versatile Routing Platform (VRP) software, the

S5700S-LI provides a large switching capacity and high-density GE ports. The S5700S-LI i

enterprise network scenarios. For example, it can function as an access or aggregation switch on a campus

network, a gigabit access switch in an Internet data center (IDC), or a desktop switch to provide 1000 Mbit/

s access for terminals. The S5700S-LI is easy to install and maintain, reducing workloads for network planning,

construction, and maintenance. The S5700S-LI uses adv

technologies, helping enterprise customers build a next generation IT network.

Product Features and highlights

Innovative Energy Saving Design

• The S5700S-LI offer customers extensive selection of energy-saving with standard mode, basic mode

and advanced mode that accommodates most needs. By matching port link down/up, optical-module

in-place/out of place, port shut down/undo shutdown, idle/busy period to increase the proportion of

the dynamic energy-saving to reduce the power consumption. The S5700S-LI series reduces energy

consumption without compromising system performance, ensuring good user experience. The S5700-LI

adopts multiple cutting-edge energy-saving designs, including Energy Efficient Ethernet (EEE), port energy

detection, dynamic CPU frequency adjustment, and device sleeping.

Comprehensive reliability mechanisms

• Besides STP, RSTP, and MSTP, the S5700S-LI supports enhanced Ethernet reliability technologies such

as Smart Link and RRPP (Rapid Ring Protection Protocol), which implement millisecond-level protection

switchover and ensure network reliability. It also provides Smart Link multi-instance and RRPP multi-

instance to implement load balancing among links, optimizing bandwidth usage.

• The S5700S-LI supports the Smart Ethernet Protection (SEP) protocol, a ring network protocol applied

to the link layer on an Ethernet network. SEP can be used on open ring networks and can be deployed

on upper-layer aggregation devices to provide fast switchover (within 50 ms), ensuring non-stop

transmission of services. SEP features simplicity, high reliability, fast switchover, easy maintenance, and

flexible topology, facilitating network planning and management.

• Complying with IEEE 802.3ah and 802.1ag, the S5700S-LI supports point-to-point Ethernet fault

management and can detect faults in the last mile of an Ethernet link to users.

Well-designed QoS policies and security mechanisms

• The S5700S-LI implements complex traffic classification based on packet information such as the 5-tuple,

IP precedence, ToS, DSCP, IP protocol type, ICMP type, TCP/UDP port number, VLAN ID, Ethernet protocol

type. ACLs can be applied to inbound or outbound direction on an interface. The S5700S-LI supports

a flow-based two-rate three-color CAR. Each port supports eight priority queues and multiple queue

scheduling algorithms such as WRR, DRR, SP, WRR+SP, and DRR+SP. All of these ensure the quality of

voice, video, and data services.

• The S5700S-LI provides multiple security measures to defend against Denial of Service (DoS) attacks,

and attacks against networks or users. DoS attack types include SYN Flood attacks, Land attacks, Smurf

attacks, 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

flood attacks. DoS attacks that change the CHADDR field in DHCP packets are also attacks against users.

• The S5700S-LI supports DHCP snooping, which discards invalid packets that do not match any binding

entries, such as ARP spoofing packets and IP spoofing packets. This prevents man-in-the-middle attacks

to campus networks that hackers initiate by using ARP pack

can be configured as a trusted interface to protect the system against bogus DHCP server attacks.

• The S5700S-LI supports strict ARP learning, which prevents ARP spoofing attacks that will exhaust ARP

entries. It also provides IP source check to prevent DoS attacks caused by MAC address spoofing, IP

address spoofing, and MAC/IP spoofing.

• The S5700S-LI sup

authentication on a per port basis, as well as Portal authentication on a per VLANIF interface basis. The

S5700S-LI also supports NAC. The S5700S-LI authenticates users based on statically or dynamically bound

user information such as the user name, IP address, MAC address, VLAN ID, access interface, and flag

indicating whether antivirus software is installed. VLANs, QoS policies, and ACLs can be applied to users

dynamically.

• The S5700S-LI can limit the number of MAC addresses learned on an interface to prevent attackers from

exhausting MAC address entries by using bogus source MAC addresses. This function minimizes packet

flooding that occurs when MAC addresses of users cannot be found in the MAC address table.

Easy deployment and maintenance free

• The S5700S-LI supports automatic configuration, plug-and-play, and batch remote upgrade. These

capabilities simplify device management and maintenance and reduce maintenance costs. The S5700S-

LI supports SNMP v1/v2c/v3 and provides flexible methods for managing devices. Users can manage the

S5700S-LI using the CLI and web-based NMS. The NQA function helps users with network planning and

upgrading. In addition, the S5700S-LI supports NTP, SSH v2, HWTACACS+, RMON, log hosts, and port-

based traffic statistics.

• 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 t

o the client in batches. In addition, the

2

configuration delivery result can be queried. The Commander can collect and display power consumption

on the entire network.

• The S5700S-LI supports GARP VLAN Registration Protocol(GVRP), which dynamically distributes, registers,

and propagates VLAN attributes to reduce manual configuration workloads of network administrators

and to ensure correct VLAN configuration. In a comple

configuration and reduces network communication faults caused by incorrect VLAN configuration. The

S5700S-LI also supports VLAN Central Management Protocol (VCMP) and VLAN-Based Spanning Tree

(VBST) protocol.

• The S5700S-LI supports MUX VLAN. MUX VLAN isolates Layer 2 traffic between interfaces in a VLAN.

Interfaces in a subordinate separate VLAN can communic

communicate with each other. MUX VLAN is usually used on an enterprise intranet to isolate user

interfaces from each other but allow them to communicate with server interfaces. This function prevents

communication between network devices connected to certain interfaces or interface groups but allows

the devices to communicate with the default gateway.

Fine-grained traffic management

• The S5700S-LI supports the Sampled Flow (sFlow) function, which uses a sampling mechanism to obtain

statistics about traffic forwarded on a network and sends the statistics to the Collector in real time. The

Collector analyzes traffic statistics to help customers manage network traffic efficiently.
