Huawei CloudEngine S5731-S32ST4X – Product Information
Product Overview
The Huawei CloudEngine S5731-S32ST4X is a high-performance standard gigabit access switch within the CloudEngine S5731-S series. It features a hybrid port design with 8 copper Gigabit Ethernet ports, 24 SFP Gigabit fiber ports, and 4 10-Gigabit SFP+ uplink ports, offering exceptional network flexibility for diverse deployment scenarios.
Built on Huawei’s unified Versatile Routing Platform (VRP), the CloudEngine S5731-S32ST4X provides enhanced Layer 3 features, simplified Operations & Maintenance (O&M), Intelligent Stack (iStack) technology — allowing multiple stacking-capable switches to function as a single logical switch — flexible Ethernet networking, and mature IPv6 features. The switch supports 1+1 power redundancy with pluggable AC and DC power modules.
Key highlights include:
-
Hybrid fiber/copper connectivity with 24 GE SFP ports (configurable to 2.5GE) and 8 copper ports
-
10GE uplink capacity via 4 SFP+ ports
-
1+1 power redundancy support
-
Intelligent Stack (iStack) for simplified network management
-
VXLAN L2 and L3 gateway support with centralized and distributed gateways
-
SVF (Super Virtual Fabric) for plug-and-play client deployment
-
64,000 MAC entries with comprehensive MAC management features
-
Built-in security probes for network-wide collaborative security protection
The CloudEngine S5731-S series is widely used in enterprise campus access and aggregation, as well as data center access scenarios.
