Huawei's core switches, including the CloudEngine S8700 and S6700 series, deliver high-performance, scalable, and secure solutions for enterprise and data center networks.

Overview of Huawei Core Switches

Huawei offers a broad portfolio of network switches designed for data centers, enterprise campuses, and high-end networks, supporting digital transformation, virtualization, and cloud services . Core switches are engineered for high bandwidth, low latency, and high availability, making them suitable for large-scale deployments and mission-critical applications .

CloudEngine S8700 Series

The CloudEngine S8700 Series represents Huawei's flagship modular core switches for large enterprises and data centers . Key features include:

• Modular chassis: Models like S8700‑04, S8700‑06, and S8700‑10 support up to 18 line card slots, allowing flexible port configurations.
• High bandwidth: Up to 16 Tbps switching capacity.
• Port flexibility: Mix of 10/25GbE access ports with 100/400GbE fabric uplinks.
• Advanced hardware acceleration: Silicon-based TCP offload, VXLAN gateway, and overlay switching with BGP-EVPN.
• High availability: Hot-swappable MPUs, LPUs, fans, and power modules with N+1 redundancy (AC/DC options).
• Security and reliability: MACsec hardware encryption per port, trusted boot, ARP/NDP protection, and TCAM-based rate-limiting for DDoS mitigation.
• Network scalability: Full CSS 2.0 chassis clustering for any-to-any core spine fabrics, MPLS EVPN, SRVPN, and L3 multilayer aggregation support. These features make the S8700 series ideal for next-generation IT networks, supporting high-density, low-latency, and secure data center fabrics .

S6700 Series

The S6700 Series is a high-performance 10G switch that can function as a core switch in campus networks or as an access switch in data centers . Highlights include:

• Port density: Up to 48 line-speed 10GE ports.
• High forwarding performance: Supports 1GE and 10GE access with flexible optical module identification.
• Security features: DHCP snooping, ARP spoofing prevention, IP/MAC source checks, and 802.1x authentication.
• Redundancy and reliability: VRRP support, E-Trunk for link backup, and Smart Ethernet Protection (SEP) for millisecond-level failover.
• QoS and traffic management: Comprehensive QoS policies and buffer scheduling for high-volume traffic. The S6700 is suitable for campus core aggregation and medium-scale data center access, providing a balance of performance, security, and manageability .

Applications and Benefits

Huawei core switches are widely deployed in finance, education, manufacturing, public services, and cloud data centers . They offer:

• High availability and reliability for mission-critical services.
• Scalability to support growing network demands.
• Automation and programmability for simplified network management.
• Security with hardware-based encryption and advanced access control.
