The S2700EI series Ethernet switches (S2700EI for short) are next-generation energy-saving 100M Ethernet intelligent switches.
The S2700EI utilizes cutting-edge switching technologies and Huawei Versatile Routing Platform (VRP) software to meet the demand for multi-service provisioning and access on Ethernet networks. It is easy to install and maintain and supports flexible VLAN deployment, comprehensive security and QoS policies, and energy-saving technologies. These features help enterprise customers build a next-generation IT network.

Huawei S2700EI Series Switches Characteristics:
Easy Operation and Maintenance
The S2700EI supports Easy-Operation, which implements easy installation, configuration, monitoring, and troubleshooting. This technology greatly reduces installation and configuration costs and engineering costs, and improves upgrade efficiency. The S2700EI provides the CLI and web platform, supports alarm management and visualized configuration, and replacement of faulty devices.
The S2700EI uses the ASIC chip and fanless design, which reduces mechanical faults and protects the equipment against damages caused by condensed water and dusts.
Flexible Service Control
The S2700EI supports various ACLs. ACL rules can be applied to VLANs to flexibly control traffic on interfaces and schedule resources in VLANs.
The S2700EI supports VLAN assignment based on interfaces, MAC addresses, protocols, and IP subnets. It applies to networks where users move frequently and networks demanding high security.
The S2700EI supports GVRP, which dynamically distributes, registers, and propagates VLAN attributes to reduce the manual configuration workloads of network administrators and ensure correct VLAN configuration. In addition, the S2700EI supports SSHv2, HWTACACS, RMON, interface-based traffic statistics, and NQA to help in network planning and upgrading.
Various Security Measures
The S2700EI supports DHCP snooping, which generates user binding entries based on MAC addresses, IP addresses, IP address leases, VLAN IDs, and interface numbers of users. The DHCP snooping function protects networks against common attacks such as bogus IP packet attacks, man-in-the-middle attacks, and bogus DHCP server attacks.
The S2700EI can limit the number of MAC addresses learned on an interface to prevent packet flooding that occurs when an attacker frequently changes source MAC addresses.
The S2700EI supports strict ARP learning. This feature prevents ARP spoofing attackers from exhausting ARP entries so that users can connect to the Internet normally. It provides IP source check to prevent DoS attacks caused by IP address spoofing.
The S2700EI supports centralized MAC address authentication and 802.1x authentication. It authenticates users based on static or dynamic user binding information such as the user name, IP address, MAC address, VLAN ID, and interface number. VLANs and ACLs can be applied to users dynamically.
The S2700EI PWR provides improved PoE solutions. You can configure whether and when a PoE port supplies power. The S2700EI PWR can use PoE power supplies with different power levels to provide -48V DC power for powered devices (PDs), such as IP phones, WLAN APs, and Bluetooth APs. As the power sourcing equipment (PSE), the S2700EI PWR complies with IEEE 802.3af and 802.3at (PoE+) and can supply power to non-standard PDs. PoE ports can work in power-saving mode. Each 802.3at-enabled interface can provide 30 W power, so the S2700EI can connect to high-power terminals.
Various Reliability Mechanisms
The S2700EI supports iStack, which virtualizes multiple switches into one logical switch. iStack improves the switching capacity and enhances reliability and scalability. The stacked switches are managed using a single IP address, which greatly reduces system operation and maintenance costs.
Besides STP, RSTP, and MSTP, the S2700EI also supports enhanced Ethernet reliability technologies such as Smart Link and RRPP, which implement millisecond-level protection switching and ensure network reliability.
The S2700EI supports the Smart Ethernet Protection (SEP) protocol, which is a ring network protocol applied to the link layer of an Ethernet network. SEP provides fast switchover within several milliseconds without interrupting services. SEP features simplicity, high reliability, high switchover performance, convenient maintenance, and flexible topology and enables users to manage and plan networks conveniently.
The S2700EI supports G.8032, also called Ethernet Ring Protection Switch (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 fast protection switching on Ethernet. ERPS supports multiple services and provides flexible networking, reducing the OPEX and CAPEX.
Comprehensive QoS Policies
The S2700EI supports complex traffic classification based on VLAN IDs, MAC addresses, IP protocols, source addresses, destination addresses, priorities, or TCP or UDP port numbers of packets. By limiting the traffic rate based on flows, the S2700EI implements line-speed forwarding on each interface to ensure high quality of the voice, video, and data services. Each interface supports eight queues and multiple queue scheduling algorithms such as WRR, SP, and WRR+SP.
Powerful Surge Protection Capability
The S2700 adopts a Huawei patented surge protection technique to prevent lightning induced overvoltage. All interfaces of the S2700 have a surge protection capability of 6 kV. The Huawei patented surge protection technique greatly reduces the possibility of lightning damages on the equipment even in atrocious environments or in scenarios where grounding cannot be implemented.
The S2700EI uses an energy-saving integrated circuit design to ensure even heat dissipation. Idle ports can enter the sleep mode to further reduce power consumption. The S2700EI generates no noises because it does not have any fans. Radiation of the S2700EI is within the range of radiation standards for electric appliances and has no harm to the human body.
