In modern campus and enterprise networks, the demands for ultra-high-speed connectivity and seamless management are unparalleled. The Huawei S6750-H Switch series meets these challenges head-on—offering robust options like 25GE downlinks, 100GE uplinks, and an advanced 36-port 100GE model (H36C). As agile Aggregation Switches and Core Switches, they deliver scalable performance, virtualization, and intelligent O&M capabilities to future-proof your network.
Overview of S6750-H Models
| Model | Access Ports | Uplink Ports | Capacity / Forwarding |
| S6750-H48Y8C | 48 × 25 GE SFP28 | 8 × 100 GE QSFP28 (auto 40/100GE) | 4 Tbps / 1200 Mpps |
| S6750-H36C | — | 36 × 100 GE QSFP28 | 7.2 Tbps / 1200 Mpps |
| S6750-H48Y8C-CI | Same as H48Y8C | Same + extension slot | Same density + CI slot |
✓ The H48Y8C is optimized for campuses needing up to 25GE edge density.
✓ The H36C shifts consensus to full-blown 100GE density for spine/aggregation layers.
✓ “CI” models support modular expansion and hot-swappable components.
Deep-Dive Feature Highlights
⚡ Ultra High-Speed Uplinks
- H48Y8C: 8×100GE uplinks auto-negotiating between 40/100GE.
- H36C: Full 36×100GE ports create an exceptionally dense core/spine switch.
🧠 Layer‑3 Intelligence & Virtualization
Runs on VRP with full multicast/routing suite—OSPF, BGP, RIPng, IS-IS, VRRP, ECMP—and VXLAN/BGP-EVPN overlay support. H36C also supports MACsec encryption on all ports for secure data paths.
🔐 Enterprise Security & Resilience
Advanced protection includes ACL filtering, DHCP/ARP snooping, DoS/DDoS mitigation, SEP/ERPS rings (<50 ms failover), and MACsec support on H36C.
📈 Intelligent O&M & Telemetry
Featuring in-situ telemetry and CampusInsight integration, the S6750-H supports predictive maintenance and QoE monitoring, ensuring proactive network management.
🧩 Hybrid Design & Expandability
CI models provide onboard compute capability and modular flexibility. Combined with NETCONF/ YANG, Python OPS, and open programmability, they support DevOps-style automation.
Real-World Deployments & Use Cases
A. Spine/Core in Large Campuses
In higher-ed environments, H36C is used as the spine, interconnecting multiple 25/100GE access/routing layers. VXLAN overlays handle multi-tenant student services, while MACsec ensures security compliance across data flows.
B. Enterprise Aggregation
H48Y8C acts as a 25GE-to-100GE aggregation point in mid-sized campuses. With dual power supplies and SSD telemetry, network ops report a 40% decrease in downtime incidents.
C. Cloud-Ready Core for Finance
HIPAA/PCI-compliant facilities deploying H36C servers greenlight MACsec for encrypting traffic between floors, ensuring high security and compliance-grade auditing.
Deployment & Management Experience
- Zero-touch provisioning: Template-based configs deploy via USB or iMaster NCE.
- Predictive O&M: Telemetry dashboards highlight anomalies before they affect users.
- Hot confinement & expansions: CI slot allows future-proof service insertion.
- Flexible upgrades: Scalable uplinks and VXLAN fabric growth with no downtime.
