For IT teams managing sprawling networks, knowing the exact Huawei switch model in your rack isn’t just administrative trivia—it’s mission-critical. Whether you’re troubleshooting performance drops, ordering compatible modules, or planning firmware upgrades, a mismatched model number can derail operations. The Huawei S5720, S6730, or older series like the S3700 each have distinct capabilities, from PoE budgets to Layer 3 routing support. But how do you quickly confirm which device you’re dealing with? Beyond the obvious sticker checks, hidden pitfalls like faded labels or firmware mismatches can lead to costly errors. This guide dives into foolproof methods to identify your Huawei switch, explains why accuracy matters for network health, and tackles scenarios where model confusion risks security or scalability.
Why Bother Checking the Huawei Switch Model?
Let’s cut to the chase: Skipping this step is like buying tires without checking your car’s make. Suppose you assume a Huawei S5720-28X-SI supports PoE+ but later discover it’s a non-PoE variant—your IP cameras or VoIP phones suddenly go dark. Worse, deploying an unsupported firmware update could brick the device.
Step 1: Physical Inspection
Start with the obvious. Most Huawei switches display the model on a label near the power port or front panel. Look for codes like S5720-52X-PWR-SI or S6730S-E24P6S-A. If the label is scratched or missing (common in dusty server rooms), power down the device and check the rear chassis engraving. Pro tip: Snap a photo of the label during installation to avoid future headaches.
Step 2: CLI Commands
No physical access? Log in via SSH or console cable. Once in the CLI, type:
display version This command reveals the model, software version, and uptime. For granular details, use:
display device manufacture-info You’ll see the Huawei switch model, serial number, and manufacturing date. Notice discrepancies? A used switch might have unofficial parts, affecting warranty claims.
Step 3: Web Interface
Prefer GUIs? Open the switch’s IP in a browser, navigate to Device > System Info. The dashboard lists the model, MAC address, and current load. Cross-reference this with Huawei’s official documentation—some older models like the S3700 lack Layer 3 features found in newer S5720 or S6730 series.
When Model Misidentification Backfires
Imagine this: Your team deploys an ACL policy tailored for a Huawei S6730S only to realize the switch is an S5720 with limited QoS options. Traffic prioritization fails, causing VoIP call drops. Here’s how to avoid these disasters:
Case 1: Firmware Upgrades
Huawei’s iMaster NCE platform requires precise model matching for patches. Uploading an S6700-specific firmware to an S5720 triggers error alerts or partial feature loss. Always download updates from Huawei’s support portal using the exact switch model.
Case 2: Feature Compatibility
Planning to enable VXLAN or EVPN? The Huawei S6730-H series supports these advanced protocols, while the S5720-LI model doesn’t. A quick display current-configuration command confirms whether your device has the required licenses or hardware.
Case 3: Replacement Parts
Ordering a replacement power supply for a Huawei S5720-52X-PWR-SI? The “-PWR” suffix matters—non-PWR models use standard AC inputs. Mixing these up risks overheating or power failures.
Troubleshooting Common Identification Hurdles
Problem: The Label Is Illegible
If the model sticker is unreadable, use the serial number. Huawei’s serials often embed the model code. For example, “210235S5720-52X-SI” includes the S5720-52X-SI identifier. Contact Huawei support with the serial to retrieve full specs.
Problem: Virtual vs. Physical Switches
Working with a CloudEngine S12700E virtual switch? Run display version all to distinguish it from physical hardware. Virtual models may lack certain ASIC-dependent features.
Problem: Third-Party Modifications
Refurbished switches sometimes have aftermarket parts. Run display elabel to view the electronic label—any tampering here voids warranties.
Beyond Basics: Why Model Knowledge Shapes Network Strategy
Identifying your Huawei switch model isn’t just about avoiding mistakes—it’s about unlocking potential. Newer models like the S6730-S24T6S support 10G uplinks and MACsec encryption, ideal for financial or healthcare networks. Older S5700 series? They’re cost-effective for small offices but lack StackWise-like stacking capabilities.
Use Huawei’s E-Label tool for batch operations. Automate model checks across hundreds of switches via Python scripts using NetConf APIs. For MSPs managing client networks, documenting each device’s model streamlines audits and compliance reporting.
In a world where network downtime costs thousands per minute, accurately verifying your Huawei switch model isn’t optional—it’s insurance. From CLI hacks to decoding serial numbers, these methods ensure you’re never blindsided by compatibility gaps or feature limitations. Next time you’re knee-deep in config files or troubleshooting a laggy VLAN, remember: The switch’s model isn’t just a code. It’s the blueprint for everything your network can (or can’t) achieve. Bookmark this guide, train your team on these steps, and treat model checks as non-negotiable as backup routines. After all, in networking, what you don’t know can hurt you.
