Summary
For a 2026 campus network requiring high-density 10G access with multiple 100G-class uplinks, the H3C S6812/S6813 and Huawei CloudEngine S6730-H / S6730-H-V2 series represent the closest functional equivalents. Both target a configuration of 48x10G downlinks paired with 6x QSFP28 uplinks (40/100G on Huawei, 100G on H3C).
The most critical practical difference often isn’t the brand, but the uplink deliverables:
- H3C positions the S6812/S6813 48-port models with 6x100G QSFP28 ports.
- Huawei’s S6730-H-V2 specifies that all ports support 40GE by default, requiring the purchase of RTU licenses to upgrade from 40GE to 100GE.
Therefore, a meaningful 2026 comparison should be based on the role (where the switch is deployed) and the deliverables (actual uplink speed on day one), before considering high-availability design and operational visibility.
The Importance of This Comparison
Modern campus networks increasingly resemble cloud architectures:
- More 10G endpoints (workstations, lab equipment, CCTV aggregation, production lines).
- Increased network segmentation (VLANs, Layer 3 at the edge, sometimes overlays).
- Higher uplink expectations, with 100G becoming standard for high-density closets.
Choosing the wrong “equivalent” model leads to predictable issues:
- Similar port templates can mask different uplink speed assumptions (40G default vs. 100G from day one), causing discrepancies between quotes and actual outcomes.
- Differing high-availability (HA) models affect maintenance windows and failure blast radius.
- Variations in operational tooling impact troubleshooting and long-term operational expenditure (OPEX).
Core Evaluation Metrics
We will evaluate both platforms across five consistent categories:
| Category | What We Compare | Why It Matters |
|---|---|---|
| Role Fit | IDF Access vs. Building Distribution vs. Edge Room | The same model can perform very differently depending on its layer in the network. |
| Port Template | 10G Downlinks + Uplink Count/Type | Determines if switches are truly functionally equivalent. |
| Uplink Reality | Default Uplink Speed + Licensing/Activation | Defines what you can actually deploy from the start. |
| HA Design Options | Stacking/Virtualization vs. M-LAG-like Designs | Controls uptime during failures and maintenance upgrades. |
| Operations & Visibility | Telemetry, Automation Hooks, Troubleshooting Workflow | Determines long-term network stability and operational costs. |
Models in Scope

Quick Specification & Role Snapshot
| Brand / Model | Downlinks | Uplinks | Switching Capacity | Forwarding Rate | Notable Features | Best-Fit Campus Role |
|---|---|---|---|---|---|---|
| H3C S6812-48X6C | 48x10G SFP+ | 6x100G QSFP28 | 2160 Gbps | 600 Mpps | IRF2, DRNI (M-LAG), VXLAN+EVPN, DCB | High-density IDF Access / Edge Room ToR |
| H3C S6813-48X6C | 48x10G SFP+ | 6x100G QSFP28 | 2160 Gbps | 1050 Mpps | Same as above; higher forwarding | High-density IDF Access with heavier concurrency |
| Huawei S6730-H48X6C | 48x10G SFP+ | 6×40/100G QSFP28 | 2.16/2.4 Tbps | 490 Mpps | Direct template equivalent | High-density IDF Access / Building Edge |

Dimension 1: Role Fit & Port Template
Comparison starts with the intended deployment location:
- Role A – High-Density IDF Access (Wiring Closet)
Goal: Standardize a repeatable template with 48x10G downlinks and multiple 100G-class uplinks to distribution/core.
- H3C explicitly positions S6812/S6813 for high-density 10GE and ToR use.
- Huawei positions S6730-H-V2 for enterprise campus and aggregation.
- Role B – Building Distribution / Aggregation
Here, uplink density and performance headroom are paramount. A model like the Huawei S6750-H48X8C (with 8x QSFP28 uplinks) becomes a more relevant comparison for this role than any 6-uplink switch.
Key Takeaway: For a repeatable IDF template, compare H3C S6812/S6813 against Huawei S6730-H(-V2). For aggregating multiple closets, compare against the Huawei S6750-H.
Dimension 2: Uplink Reality
The most crucial differentiator: A QSFP28 port is not a deliverable; a functional 100GE uplink is.
- Huawei’s S6730-H-V2 datasheet clearly states: “All ports support 40GE by default.” Upgrading to 100GE requires purchasing RTU licenses.
- H3C’s S6812/S6813 48-port models list 6x100G QSFP28 ports in their base description.
Practical Guidance:
- If your design depends on 6x100G uplinks per closet, treat Huawei’s V2 uplinks as “100G-capable, dependent on RTU license” and validate costs early.
- If your plan allows starting with 40G uplinks and upgrading later, Huawei’s licensing path may suit a phased rollout.
Dimension 3: Performance Headroom
Specifications matter most when they correlate to real-world performance issues like jitter or microbursts.
- H3C shows a clear internal distinction: S6812 (600 Mpps) vs. S6813 (1050 Mpps).
- Huawei S6730-H/V2 lists 490 Mpps, while the S6750-H lists 1200 Mpps.
Interpreting Specs for Campus Designs:
| Metric | What It Indicates | When It Matters Most | Primary Role |
|---|---|---|---|
| Forwarding (Mpps) | Stability under concurrency & small packets; policy-heavy traffic. | Many short flows; heavy ACL/QoS; high visibility overhead. | IDF Access / Edge Room |
| Uplink Count + Speed | Perceived oversubscription. | During growth, fan-in, or multi-closet aggregation. | Distribution / Aggregation |
| Switching Capacity (Tbps) | Upper limit headroom. | In high-traffic aggregation blocks. | Distribution / Collapsed Core |
- If traffic is predictable and north-south, uplink capacity is often the bottleneck, not Mpps.
- For closets with heavy segmentation, security policies, or “spiky” workloads, higher forwarding (like S6813 or S6750-H) can be valuable.
Dimension 4: High-Availability (HA) Design
A fair comparison asks about operational impact, not just feature support.
- H3C highlights IRF2 for virtualization and DRNI (M-LAG) for dual-homing with independent upgrades.
- Huawei’s S6750-H series describes iStack, which virtualizes multiple switches into one logical device for redundancy and simplified management.
Key Operator Questions:
- Maintenance: Can I upgrade one unit with minimal interruption? (DRNI/iStack facilitate this).
- Failure Domain: What is the blast radius if something fails? Virtualization (IRF2/iStack) simplifies ops but consolidates failure domains. M-LAG-style designs preserve independence but require disciplined implementation.
Fair Takeaway: Choose the HA pattern your team can operate reliably, not just the one with the best specifications.
Dimension 5: Operations & Visibility
This area often dictates long-term operational efficiency.
- Huawei: Measurement + Telemetry + Automation
The S6750-H series datasheet emphasizes concrete operational features:
- IFIT (In-situ Flow Information Telemetry) for in-band measurement of packet loss and delay.
- Telemetry feeding into Huawei iMaster NCE-CampusInsight for analytics.
- Python-based OPS for programmable automation.
- VXLAN + BGP EVPN configurable via NETCONF/YANG.
- MACsec for link-layer security.
The S6730-H-V2 also includes VXLAN and IFIT support.
- H3C: ToR/Data Center Features for Campus Edge
H3C’s emphasis for the S681X series includes:
- VXLAN and MP-BGP EVPN support.
- DCB features (PFC/ETS/DCBX) for lossless Ethernet, relevant for edge rooms with storage/compute workloads.
- Programmable chips and SDN/controller integration.
Fair Takeaway: If your campus includes edge rooms with data-center-like workloads, H3C’s feature set aligns well. If campus-wide experience visibility and centralized analytics are priorities, Huawei’s explicit IFIT/telemetry tooling offers significant operational advantages.

| Collapsed Distribution/Core | Uplink Density | Aggregation Switch | (Consider an H3C aggregation-class switch) | You require 8×40/100G uplinks and higher headroom (S6750-H48X8C). |
| Future Overlay Segmentation | Operational Complexity | VXLAN-Capable Edge | You plan to run VXLAN+EVPN and value a DC-leaning feature set. | You plan to run VXLAN+EVPN and want NETCONF/YANG with campus analytics workflows. |
FAQs
Q1: What defines an “equivalent” campus switch for H3C S6812/S6813?
A: It refers to switches serving the same role with a similar port template: typically 48x10G downlinks and multiple 100G-class uplinks for high-density IDF access. H3C’s models offer 6x100G QSFP28, while Huawei’s S6730-H(-V2) offers 6×40/100G QSFP28 (40G by default).
Q2: Why aren’t “40/100G uplinks” and “6x100G uplinks” automatically the same?
A: The deliverable speed differs. Huawei’s S6730-H-V2 explicitly states 40GE as the default, requiring an RTU license for 100GE, whereas H3C’s specification lists 100G ports.
Q3: Which Huawei model is the closest match to a 48x10G + 6-uplink design?
A: The Huawei CloudEngine S6730-H48X6C (and its V2 variant) is the closest template match.
Q4: When should I compare against the Huawei S6750-H48X8C instead?
A: When the switch acts as a building distribution or collapsed aggregation node, where higher uplink density (8x QSFP28) and greater performance headroom are primary requirements.
Q5: Is the S6813 “better” than the S6812?
A: Not universally. The S6813 provides higher forwarding capacity (1050 Mpps vs. 600 Mpps), which can be important under heavy concurrency or with policy/visibility overhead, but the S6812 may suffice for less demanding environments.
Q6: Does Huawei provide built-in tools for delay/loss visibility?
A: Yes. Huawei’s S6750-H and S6730-H-V2 datasheets describe IFIT (In-situ Flow Information Telemetry) for in-band measurement of delay and packet loss.
Q7: Should I care about VXLAN support if I don’t plan to use it now?
A: Primarily as future-proofing. Both platforms support VXLAN+EVPN. It matters most if you have a concrete overlay network roadmap.
Q8: What HA options are available on these platforms?
A: H3C offers IRF2 (virtualization) and DRNI (M-LAG). Huawei offers iStack for switch virtualization and redundancy.
Q9: Is MACsec relevant for campus switching in 2026?
A: Yes, particularly in regulated environments or where link-layer encryption is required between switches. Huawei’s S6750-H series explicitly lists MACsec support.
Q10: What’s a common reason users still complain after a switch upgrade?
A: Often, uplink capacity and architecture. If the delivered uplink speed (e.g., 40G vs. planned 100G) or HA design doesn’t match the actual traffic pattern, access-layer upgrades won’t improve the user experience.
Q11: How do I decide between a 6-uplink and an 8-uplink model?
A: If you are aggregating multiple closets or anticipate rapid growth, an 8-uplink model (like the S6750-H) provides more design freedom and reduces fan-in pressure.
Q12: Which platform appears more “campus-operations oriented”?
A: On paper, Huawei’s S6750-H datasheet is very explicit about operational workflows, highlighting IFIT, telemetry to CampusInsight, Python OPS, and cloud-based management.
Q13: Which platform appears more “edge room / mini-DC oriented”?
A: H3C’s S681X series emphasizes data-center features like DCB (PFC/ETS/DCBX) and EVPN, which map well to edge rooms with storage or compute workloads.
Conclusion
A fair 2026 cross-brand comparison focuses on role (IDF access vs. distribution) and deliverables (actual uplink speed) over marketing labels. The H3C S6812/S6813 provides a clear 48x10G + 6x100G template with data-center-leaning features like IRF2, DRNI, VXLAN/EVPN, and DCB.
Huawei’s S6730-H-V2 and S6750-H families cover similar campus roles while placing strong emphasis on measurement/visibility (IFIT) and telemetry analytics. A key differentiator is the explicit note on the S6730-H-V2 regarding 40G default uplinks with an RTU license required for 100G.
