Maintenance free, easy deployment, and easy management
The S2700 supports automatic configuration and plug-and-play, which dramatically reduces maintenance costs. It adopts new application-specific integrated circuit (ASIC) switching technique and a fan-free design. This design reduces mechanical faults and protects the device against damages caused by condensed water and dust, reducing 53% of the maintenance workloads.
The S2700 supports batch remote upgrade, which makes the device easy to use and deploy. It provides a Web NMS system with a user-friendly GUI to implement automatic topology discovery, alarm management, and visual configuration, facilitating operation and maintenance. The NQA function helps users with network planning and upgrades. In addition, the S2700 supports HGMP v2, SSH v2, HWTACACS+, RMON, and port-based traffic statistics.
The S2700 supports GVRP, which dynamically distributes, registers, and propagates VLAN attributes to reduce manual configuration workloads of network administrators and to ensure correct VLAN configuration.
Flexible service control
The S2700-EI supports various ACLs. ACL rules can be applied to VLANs to flexibly control ports and schedule resources in VLANs.
The S2700 supports port-based VLAN assignment and MAC address-based VLAN assignment. Port-based VLAN assignment is applicable to networks where users move frequently, and MAC address-based VLAN assignment is applicable to networks that require high security.
Excellent security features
The S2700 supports DHCP snooping, which generates user binding entries based on MAC addresses, IP addresses, IP address leases, VLAN IDs, and access interfaces of users. The DHCP snooping function protects enterprises against common attacks such as bogus IP packet attack, man-in-the-middle attack, and bogus DHCP server attack.
The S2700 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. The S2700 can also limit the number of ARP entries to prevent ARP spoofing attacks. In addition, it provides the IP source check function to prevent malicious users from using spoofed IP address to initiate DoS attacks.
The S2700 supports centralized MAC address authentication, 802.1x authentication, and NAC. It 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 S2700 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. In its role as power sourcing equipment (PSE), the S2700 PWR complies with IEEE 802.3af and 802.3at (PoE+) and can work with PDs that are incompatible with 802.3af or 802.3at. Each port provides a maximum of 30 W power, complying with IEEE 802.3at. The PoE+ function increases the maximum power of each port and implements intelligent power management for high-power consumption applications. This facilitates the use of PDs. PoE ports can work in power-saving mode.
The S2700 supports intelligent stacking (iStack). Multiple S2700s can be connected with stack cables to set up a stack, which functions as a virtual switch. The backup switch takes over services when the master switch fails, reducing service interruption time. Stacks support intelligent upgrade so that users do not need to change the software version of a switch when adding it to a stack. The iStack function allows users to connect multiple switches with stack cables to expand system capacity. These switches can be managed using a single IP address, which greatly reduces the costs of system expansion, operation, and maintenance. Compared with traditional networking technologies, iStack has advantages in scalability, reliability, and system architecture.
Comprehensive QoS policies
The S2700 supports complex traffic classification based on VLAN IDs, source MAC/IP addresses, destination MAC/IP addresses, IP protocols, priorities, or port numbers of packets. By limiting the traffic rate based on traffic classification results, the S2700 implements line-speed forwarding on each port to ensure high quality of the voice, video, and data services. Each port supports four 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 ports of the S2700 have a surge protection capability of 10/700us 6 KV, complying with IEC61000-4-5. 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.
No noise, energy conservation, and low radiation
The S2700 adopts an energy-saving integrated circuit design to ensure even heat dissipation. Idle ports can enter the speed mode to further reduce power consumption. The S2700 generates no noises because it does not have any fans. Radiation of the S2700 is within the range of radiation standards for electric appliances and has no harm to the human body.
100 Mbit/s Access Rate for Terminals
The S2700 can function as a desktop access device that provides 100 Mbit/s access rate for terminals and 1000 Mbit/s uplink interfaces to communicate with uplink devices. to communicate with uplink devices.
