S5700 Core Switch

The Huawei S5700 series can be used as a core switch in small to medium enterprise networks, but it is primarily designed for access and aggregation roles in campus networks.

Core Switch Capabilities

The S5700 series offers high-density GE and multi-GE ports, with some models supporting 25GE or 100GE uplinks, which allows for high-bandwidth aggregation and interconnection between network layers (Huawei S5700 V600 Product Description) . It supports Layer 3 routing protocols such as OSPF, BGP, PIM, and IPv6, along with MPLS and EVPN features, enabling it to handle routing and traffic management typically required at the core layer (S5700 Series Datasheet) . The switches also support MLAG (Multi-Chassis Link Aggregation) for active-active redundancy, improving network reliability and link utilization .

Performance and Scalability

The S5700 is built on high-performance Ethernet network processors with programmable architectures, allowing flexible packet processing and traffic control. This makes it suitable for scalable networks where Layer 3 services and QoS policies are needed . Some models, like the S5700-LI, provide 10GE uplinks and support iStack, enabling stacking of multiple switches to increase capacity and redundancy . However, the S5700 is generally optimized for enterprise campus access or aggregation, rather than large-scale data center core deployments.

Considerations

• Network Size: For small to medium-sized enterprise networks, the S5700 can serve as a core switch, especially when combined with stacking and high-speed uplinks.
• High-Demand Environments: In large-scale or high-traffic data centers, Huawei's CloudEngine S series or higher-end core switches may be more appropriate due to higher throughput and advanced Layer 3 capabilities.
• Redundancy: The S5700 supports dual power supplies and hot-swappable fans, which are important for core deployment reliability .

Conclusion

The Huawei S5700 series can function as a core switch in scenarios where the network is not extremely large or heavily loaded, providing Layer 3 routing, high-speed uplinks, and redundancy features. For larger enterprise or data center cores, higher-end switches with greater throughput and advanced Layer 3 capabilities are recommended. The S5700 is most commonly deployed as an access or aggregation switch in campus networks but is flexible enough for smaller core deployments.
