Huawei CloudEngine S12700H-4 – Product Documentation & Specifications

Product Overview

The Huawei CloudEngine S12700H-4 is a next-generation modular core/aggregation switch designed for high-end campus networks in the Wi-Fi 6/7 fully-wireless era. As the 4-slot model in the CloudEngine S12700H series, it provides ultra-high-density GE, 10GE, 25GE, 40GE, and 100GE full-rate access ports, enabling customers to quickly build campus networks with a simplified architecture.

The S12700H-4 adopts the CLOS switching architecture and is powered by Huawei’s self-developed next-generation converged software platform, delivering a trusted system and secure data access. All key components—including Main Processing Units (MPUs), power modules, and fan modules—feature a redundancy design for carrier-grade reliability.

Key highlights of the CloudEngine S12700H-4 include:

• High performance: Supports flexible SFU boards with 100GE service ports, 72 × 10GE high-density boards, 16 × 100GE/36 × 40GE high-speed cards, and up to 512 × 10GE-PEN port capability, ideal for various large aggregation/core scenarios

• High quality: Intelligent service application identification, preferential forwarding of audio and video services with zero packet loss, reducing packet loss by 30%+ during 2 Gbps microbursts

• High reliability: Microsecond-level switchover (one-tenth of the industry average) with always-on services; 1:1 service forwarding units ensure device bandwidth remains unchanged even if any MPU or SFU fails; supports slicing, M-LAG, and stacking

• High security: Terminal identification, anti-spoofing, unauthorized access control, and MACsec supported across all models

• Wired and wireless convergence: Integrated native AC functionality for unified wired and wireless network management

The S12700H-4 is widely deployed as a core or aggregation node in medium to large-sized campus networks across industries such as government, education, finance, and enterprise.
