What Is the Huawei S5735-L?

The Huawei CloudEngine S5735-L series represents a new generation of simplified Gigabit Ethernet switches designed specifically for enterprise campus network access and “Gigabit to the Desktop” deployments. Built on high-performance hardware and powered by Huawei’s Versatile Routing Platform (VRP), the S5735-L delivers robust Layer 2/3 switching capabilities, intelligent operations, and enterprise-grade reliability—all in a compact, cost-effective form factor.

Whether you're upgrading an existing infrastructure or building a new campus network from the ground up, the Huawei S5735-L offers the flexibility, scalability, and security needed to support modern business demands—from IP phones and wireless APs to video conferencing and IoT devices.

Key Features of the Huawei S5735-L Series

Flexible Ethernet Networking with Advanced Resilience

The S5735-L supports industry-standard protocols like STP, RSTP, and MSTP, as well as Huawei’s proprietary Smart Ethernet Protection (SEP) and ITU-T G.8032-compliant Ethernet Ring Protection Switching (ERPS). These technologies enable sub-50ms failover in ring topologies, ensuring uninterrupted service even during link failures. Additionally, Smart Link provides uplink redundancy by allowing a single switch to connect to multiple aggregation devices—greatly enhancing network reliability at the access layer.

Comprehensive Security Controls

Security is built into every layer of the Huawei S5735-L. It supports per-port authentication methods including IEEE 802.1X, MAC address authentication, and hybrid modes. VLAN-based Portal authentication enables dynamic policy delivery (VLAN, QoS, ACL) based on user identity.

To combat threats, the switch includes defenses against DoS attacks (e.g., SYN flood, ICMP flood) and user-targeted exploits like rogue DHCP servers, IP/MAC spoofing, and DHCP request floods. Features like DHCP Snooping, strict ARP learning, and binding table enforcement ensure only authorized devices can communicate on the network.

PoE+ Support with Perpetual and Fast Power Delivery

Many S5735-L models (e.g., S5735-L24P4X-A1, S5735-L48P4S-A) come with integrated PoE+ (IEEE 802.3at) support, delivering up to 30W per port. This makes them ideal for powering wireless access points, IP cameras, VoIP phones, and other edge devices without requiring separate power sources.

Two standout innovations enhance PoE reliability:

• Perpetual PoE: Maintains power to connected devices during switch reboots or software upgrades.
• Fast PoE: Delivers power within seconds of startup—dramatically reducing downtime compared to traditional switches that may take 1–3 minutes.

Model Variants and Port Configurations

The Huawei S5735-L series offers a wide range of models to suit different deployment scales and requirements:

Note: Models ending in “P” (e.g., L24P4X) support PoE+. Those with “X” offer 10GE uplinks, while “S” models use standard GE SFP uplinks. “A” denotes AC power; “D” indicates DC power support.

Intelligent Stack (iStack) for Simplified Management

The Huawei S5735-L supports iStack—Huawei’s intelligent stacking technology—that virtualizes up to 9 physical switches into a single logical device. Benefits include:

▪ High Availability: Member switches provide redundancy and failover.

▪ Scalability: Easily expand port density, bandwidth, and processing power by adding units.

▪ Unified Management: Configure and monitor the entire stack from any member switch.

iStack uses service ports for stacking (no dedicated stacking modules required), reducing costs and simplifying cabling. Note: Mixed stacking between A/D and A1/D1 sub-series is not supported.

Smart Operations & Maintenance (O&M)

The S5735-L is engineered for ease of deployment and management:

▪ Easy Operation: Supports zero-touch provisioning, USB-based deployment (on models with USB ports), batch configuration, and one-click remote upgrades.

▪ Telemetry & CampusInsight: Real-time data streaming to Huawei’s CampusInsight platform enables AI-driven fault identification, user experience assurance, and proactive network optimization.

▪ eMDI for AV Services: Enhanced Media Delivery Index allows the switch to monitor and report audio/video KPIs (e.g., packet loss, jitter), enabling rapid troubleshooting of UC applications.

▪ Cloud Management: Fully compatible with Huawei’s cloud management platform for centralized control, reducing on-site O&M costs and operational expenditure (OPEX).

Advanced Licensing with N1 Software Mode

Starting from V200R019C10, the Huawei S5735-L supports the modern N1 licensing model, which simplifies software purchasing and upgrades. The N1 portfolio includes:

▪ N1 Basic: Core L2/L3 functions, IPv4/IPv6, SVF.

▪ N1 Foundation: Adds plug-and-play automation, basic monitoring, and user authentication via iMaster NCE-Campus.

▪ N1 Advanced: Includes CampusInsight analytics and intelligent O&M capabilities.

This flexible approach aligns with Huawei CloudCampus solutions and accelerates digital transformation in on-premises environments.

Why Choose the Huawei S5735-L for Your Network?

The Huawei S5735-L strikes an optimal balance between performance, intelligence, and affordability. Its combination of PoE+ readiness, millisecond-level protection protocols, scalable iStack architecture, and AI-powered O&M makes it a future-proof choice for:

▪ Enterprise office campuses

▪ Educational institutions

▪ Healthcare facilities

▪ Retail and hospitality venues

▪ Smart buildings with dense IoT deployments

With support for both on-premise and cloud management—and seamless integration into Huawei’s end-to-end networking ecosystem—the S5735-L empowers organizations to build agile, secure, and user-centric networks.

Conclusion

In today’s dynamic enterprise landscape, access-layer switches must do more than just forward packets. The Huawei CloudEngine S5735-L rises to the challenge by integrating intelligence, resilience, and simplicity into a single platform. Whether you need reliable PoE delivery for wireless infrastructure, rapid fault recovery for critical applications, or cloud-based visibility across your entire campus, the S5735-L delivers enterprise-grade performance without enterprise-grade complexity.

For IT teams seeking a scalable, secure, and smart foundation for their next-generation network, the Huawei S5735-L isn’t just an option—it’s the strategic choice.
