Brand: HUAWEI
SKU: S5731-S32ST4X-D

Product Overview

The Huawei CloudEngine S5731-S32ST4X-D is a next-generation standard gigabit access switch designed for enterprise campus networks, data center access, and metropolitan area network (MAN) access scenarios. Built on Huawei’s unified Versatile Routing Platform (VRP), this switch delivers enhanced Layer 3 features, simplified operations and maintenance (O&M), and mature IPv6 capabilities.

The switch features a flexible port configuration consisting of 8 x 10/100/1000BASE-T copper ports, 24 x GE SFP fiber ports, and 4 x 10GE SFP+ high-speed uplink ports, providing a total of 36 ports. It is equipped with a built-in DC power supply and supports front-access design for simplified maintenance in rack deployments.

Key capabilities include:

Intelligent Stack (iStack) – Virtualizes up to nine physical switches into a single logical switch, improving reliability, scalability, and management efficiency
VXLAN Support – Layer 2 and Layer 3 gateways with centralized/distributed gateway capabilities, BGP-EVPN, and NETCONF-based configuration
Super Virtual Fabric (SVF) – Simplifies network O&M by virtualizing core/aggregation switches, access switches, and APs into a single logical device with plug-and-play client support
Integrated Network Security – Built-in security probes that identify potentially malicious traffic and collaborate with Huawei HiSec Insight for network-wide security protection
Comprehensive VLAN Features – Supports 4094 VLANs, Guest VLAN, Voice VLAN, MUX VLAN, and VLAN assignment based on MAC addresses, protocols, IP subnets, policies, and ports

The switch is widely used in enterprise campus access and aggregation, as well as data center access scenarios.
