2015 Huawei Core Switch

Huawei's 2015 core switches, such as the S12700 and S9300 series, were high-performance, scalable, and resilient switches designed for enterprise and data center networks.

Key Models and Features

• Huawei S12700 Series (TAN Series): Designed for intelligent, scalable enterprise networks, the S12700 offered ultra-broadband services, integration of wired, optical, and wireless technologies, and support for CloudFabric architecture. It was ideal for enterprise backbones, digital transformation initiatives, and high-capacity campus networks (Huawei Alibaba listing) .
• Huawei S9300 Series (ING Series): Targeted medium to large enterprises, combining high-speed switching with intelligent network management. It featured energy-efficient cooling and robust performance for mission-critical applications, suitable for enterprise core layers and service provider edge/core networks .
• CloudEngine Series (CE12800, CE8800, CE7800): Although introduced slightly later, these data center switches represented Huawei's high-end core switch architecture, offering massive throughput (up to 160 Tbit/s for CE12800) and high-density line-speed ports, designed for next-generation data centers and high-end campus networks .

High Availability and Redundancy

Huawei implemented Cluster Switch System (CSS) for high availability, allowing two modular switches to operate as a single logical device with a shared control plane. One switch acts as the master and the other as standby, simplifying network topology and routing while providing redundancy. This setup supports Active-Active traffic sharing but requires careful planning for software updates due to the shared control plane . For mission-critical deployments, Huawei recommended redundant power supplies, stacking configurations (for S12700), and proactive network monitoring, often paired with iMaster NCE for centralized network management and automation .

Deployment Scenarios

Huawei core switches from 2015 were suitable for:

• Enterprise core layers: High-speed, reliable switching for large campuses and corporate networks.
• Data centers: Handling massive data traffic with low latency and high throughput.
• Service provider networks: Edge and core networks requiring bandwidth-heavy applications and high-density connectivity.
• Digital transformation initiatives: Supporting virtualization, cloud services, and Big Data applications .

Expert Tips

• Use CSS or stacking to simplify management and improve uptime.
• Pair with centralized network management tools like iMaster NCE for automation.
• Ensure energy-efficient cooling and redundant power for stable operation in high-density environments.
• Consider integration with existing network equipment carefully, as multi-vendor Active-Active setups may require spanning tree protocols to avoid port blocking . Huawei's 2015 core switches provided a robust foundation for scalable, intelligent, and high-performance networks, making them suitable for both enterprise and data center environments.
