The S3700 series enterprise switches (S3700s) are next-generation energy-saving Layer 3 switches. The S3700 utilizes cutting-edge hardware and Huawei Versatile Routing Platform (VRP) software to provide high-performance access and aggregation to an enterprise campus network. This document describes the configuration of Ethernet services, including configuring MAC address table, link aggregation, M-LAG, VLAN, QinQ, VLAN mapping, GVRP, STP/RSTP, MSTP, VBST, ERPS (G. 8032), LBDT, and Layer 2 protocol transparent transmission. Switches cannot replace routers in all scenarios because routers provide rich. Over the past year, enterprise network deployments have increasingly favored integrated Layer 3 switching over traditional router–switch separation — especially in campus, SME, and edge data center environments. Huawei's S57xx, S67xx, and CloudEngine series now dominate mid-tier procurement lists. Huawei core switch offers robust real-world performance in enterprise upgrades, delivering enhanced Layer 3 routing, superior PoE++, modular scalability, and stable integration with multi-vendor infrastructures.
