What’s the Product Characteristics of Huawei S2700 Switch (II)
Various Reliability Mechanisms
The S2700 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 S2700 also supports enhanced Ethernet reliability technologies such as Smart Link and RRPP, which implement millisecond-level protection switching and ensure network reliability.
The Huawei S2700 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 S2700 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 S2700 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 S2700 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.
Energy-saving Design
The S2700 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 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.
