Modern networks are gasping for air. Between bandwidth-hungry applications, IoT explosions, and security threats, legacy switching infrastructure often becomes the weakest link. If you’re running Huawei S5720-HI or S6720 series switches, you’ve likely hit performance ceilings or wrestled with limited future readiness. Huawei’s CloudEngine portfolio isn’t just incremental improvement—it’s a strategic leap engineered for the demands of next-gen campuses and data centers. Forget forklift upgrades; this is about seamless evolution. We’re cutting through the noise to map precise upgrade paths, detailing why newer models like the S5730 and S6730-H series deliver tangible operational advantages beyond raw specs. Whether you’re battling bottlenecks or planning a network overhaul, understanding these replacements is critical for maintaining competitive infrastructure.
The S5720-HI Evolution: Beyond Basic Gigabit
The S5720-HI series earned its stripes as a versatile workhorse for mid-sized campuses. Its strength lay in flexibility – decent PoE capabilities, Huawei’s VRP software for customization, and SVF virtualization to simplify management. But technology marches on. Newer access points, high-resolution cameras, and bandwidth-intensive applications demand more than traditional Gigabit switching can deliver.
Enter the natural successors: the S5730 series. These aren’t just replacements; they’re substantial upgrades. Take the S5730-68C-PWH-HI. It directly supersedes models like the S5720-56C-PWR-HI-AC, bringing crucial enhancements:
- Increased Port Density & Flexibility: More ports to accommodate growing device counts.
- Enhanced Multigigabit Support: Ready for Wi-Fi 6/6E/7 APs requiring 2.5G/5G/10G backhaul.
- Improved PoE Budget: Higher power budgets per port to handle next-gen powered devices.
- Modern Management: Streamlined interfaces and better integration with Huawei’s ecosystem (like iMaster NCE).
The transition is logical and preserves your investment in Huawei’s architecture while significantly boosting capability at the access layer. For core roles in smaller campuses or data center access, the S5730-68C-HI steps in for non-PoE models, offering similar uplink enhancements and future-ready performance.
S6720-SI & EI: Aggregation Gets a Major Boost
The S6720-SI and EI series served well as aggregation or core switches, offering 10G access and 40G uplinks. However, the surge in 10G server connections, high-density wireless, and emerging 25G/40G needs exposes their limitations. Modern aggregation requires higher density, faster uplinks, and smarter features.
Huawei’s answer lies in the S5732-H series. Models like the S5732-H48UM2CC replace workhorses like the S6720-56C-PWH-SI. What changes?
- Uplink Revolution: Moving from 40G to 100G uplinks (QSFP28) is a game-changer for backbone bandwidth, eliminating aggregation bottlenecks.
- Multigigabit Mastery: Native support for a wider range of speeds (100M/1G/2.5G/5G/10G) on access ports, crucial for flexible AP deployments.
- Increased Switching Capacity: Handles significantly more concurrent traffic without breaking a sweat.
- Enhanced Security & Analytics: Built-in features for deeper network visibility and threat detection.
For environments where the S6720-EI played a core/aggregation role, the S6730-H series is the clear progression, offering even greater performance and 100G readiness.
S6730-H Series: The New Aggregation & Core Powerhouse
This is where Huawei truly flexes its engineering muscle. The CloudEngine S6730-H series (like the S6730-H24X6C and S6730-H48X6C) isn’t just an upgrade; it’s a platform designed for the next decade. Replacing top-end S6720-EI models, it delivers:
- Massive Port Density: 24 or 48 native 10G SFP+ downlink ports plus six 40G/100G QSFP28 uplinks provide incredible flexibility and scalability. Need more 10G? It’s got you covered. Need 100G uplinks? Standard.
- Unmatched Performance: Terabit-level switching capacity and high forwarding rates ensure latency-sensitive applications (VoIP, video, trading) perform flawlessly even under heavy load.
- Integrated Wireless Control: Native AC functionality managing up to 1,000 APs simplifies network architecture and reduces costs.
- Advanced Security Fabric: Built-in security probes, encrypted traffic analysis (ECA), and threat deception move beyond basic ACLs to proactively defend your network.
- Seamless User Experience: Features like network virtualization and free mobility ensure users stay connected securely, regardless of location within the campus.
This series shines in demanding environments: large enterprise campuses, universities with high-density dorms/labs, government networks, and carrier edge applications. Comparing the H24X6C (24x10G) and H48X6C (48x10G) models boils down to your immediate 10G port density needs – both offer the same six powerful 100G uplinks and core feature set.
Why Upgrade Now? Beyond the Spec Sheet
Replacing functional hardware always needs justification. It’s not just about newer chipsets. Consider:
- Total Cost of Ownership (TCO): Newer switches are vastly more energy-efficient. Power savings alone can offset upgrade costs over 3-5 years. Reduced cooling needs add to this.
- Operational Efficiency: Modern management interfaces (like Huawei’s web GUI or iMaster NCE) drastically reduce configuration time, troubleshooting effort, and the risk of human error compared to managing older CLI-heavy platforms.
- Future-Proofing: Deploying switches with 100G uplinks and multi-gig access ports today means you won’t need another major upgrade in 2-3 years when bandwidth demands inevitably jump again. It’s an investment in longevity.
- Security Posture: Legacy switches often lack the advanced threat detection, encrypted traffic analysis, and automated response capabilities built into modern platforms like the S6730-H. Upgrading closes critical security gaps.
- Support & Warranty: Continuing to run EoL/EoS hardware risks expensive failures and lack of vendor support during critical outages. New hardware comes with full support and warranty.
Making the Switch: Your Huawei Migration Path
Transitioning doesn’t have to be daunting. Huawei designs its CloudEngine series for backward compatibility and gradual migration. You can often phase upgrades:
- Start at the Aggregation/Core: Replace S6720-SI/EI switches with S5732-H or S6730-H series first. This immediately boosts backbone capacity and uplink speed.
- Upgrade Access Layers: Subsequently replace S5720-HI switches with S5730 models. The newer access switches benefit from faster uplinks back to the upgraded core.
- Leverage Centralized Management: Utilize Huawei’s management platforms (e.g., iMaster NCE-Campus) to manage both old and new devices during the transition, ensuring consistency and simplifying configuration.

Investing in Uninterrupted Performance
Your network is the central nervous system of your operations. Bottlenecks at the core or access layer translate directly into lost productivity, frustrated users, and missed opportunities. Sticking with aging S5720-HI or S6720 series switches isn’t just a technical limitation; it’s a business risk. Huawei’s CloudEngine replacements – the S5730, S5732-H, and S6730-H series – offer a clear, performance-driven upgrade path. They deliver the substantial bandwidth headroom, advanced features, robust security, and operational simplicity required for modern digital business. Upgrading isn’t merely swapping hardware; it’s about ensuring your infrastructure actively enables growth rather than holding it back. If resilience, scalability, and future-readiness matter to your network strategy, migrating to these next-gen Huawei switches is a decisive step forward.
