Upgrading a Huawei switch involves three main phases: Preparation, Transfer, and Activation. 1. Preparation & Compatibility

Identify Your Model: Run display version in the CLI to find your current version and exact hardware model.

Download Files: Navigate to the Software Download page. Download the system software (.cc) and any corresponding patches (.pat).

Check Storage Space: Use dir to ensure the flash memory has enough space. Delete old, unused firmware if necessary. huawei switch firmware upgrade link

Backup Configuration: Save your current config using save and export it to an external server. 2. File Transfer (via FTP/SFTP)

You can transfer files by setting up your PC as a server and the switch as a client. Establish Connection: On the switch, enter the following:

ftp get S5700-V200R021C00SPC600.cc # Replace with your actual file name get S5700-V200R021SPH013.pat # Download the patch as well Use code with caution. Copied to clipboard Source: Sx300 Series Example 3. Activation & Reboot

Once the files are on the switch's local storage, set them for the next boot cycle. Set Startup Files:

startup system-software S5700-V200R021C00SPC600.cc startup patch S5700-V200R021SPH013.pat Use code with caution. Copied to clipboard

Verify Selection: Run display startup to confirm the "Next startup system software" is correct.

Reboot: Execute the reboot command. The switch will load the new firmware upon restart. 4. Verification

After the switch reboots, verify the upgrade with these commands:

Huawei Switch Firmware Upgrade Guide: A Step-by-Step Approach

Introduction

Huawei switches are widely used in modern networks for their reliability, scalability, and advanced features. However, like any other network device, they require periodic firmware upgrades to ensure they stay secure, efficient, and compatible with evolving network standards. Upgrading the firmware of a Huawei switch can seem daunting, but with the right guidance, it can be a straightforward process. This document aims to provide a comprehensive, step-by-step guide on how to upgrade the firmware of a Huawei switch.

Preparation

Before initiating the firmware upgrade, ensure you have: The official source for downloading Huawei switch firmware

Checked the Current Firmware Version: Log in to your Huawei switch and check the current firmware version. This information will help you determine if an upgrade is necessary and what version to upgrade to.
Selected the Correct Firmware Version: Visit the official Huawei website or contact Huawei support to find and download the latest or required firmware version for your specific switch model.
Understood the Upgrade Path: Some Huawei switches may require an intermediate firmware version before you can upgrade to the latest one. Ensure you follow the recommended upgrade path.
Backed Up Configuration: Always back up your switch's current configuration. Upgrading firmware might reset certain configurations or, in rare cases, fail, potentially causing loss of configuration.
Connected via Console or SSH: For maximum safety, performing the upgrade via a console cable or a secure SSH connection is recommended. This prevents loss of access during the upgrade.
Power Supply Stability: Ensure the switch has a stable power supply. An interruption during the upgrade can cause irreversible damage to the switch.

Firmware Upgrade Process

Step 4: Reboot

<Huawei> reboot

Confirm the reboot. The switch will load the new firmware.

1. Check Current Version

display version

Note the current VRP version. You cannot always jump major versions (e.g., V100 to V200) directly; you may need an intermediate step.

The Aftermath

By 4:15 AM, the upgrade was complete. Both supervisors were on new firmware. All 2,400 customer VLANs passed traffic. Lin Wei closed his laptop and stared at the ceiling of the NOC.

The "Huawei switch firmware upgrade link" wasn't just the download URL. It was:

The entitlement link (proving you had the right to upgrade).
The integrity link (checksums and secure boot).
The recovery link (USB boot path).
The community link (the Brazilian engineer’s thermal fix).
The human link—the memory of past failures that made him check the flash corruption before it was too late.

He smiled. Then he opened a ticket with Huawei to report the thermal curve bug. The reply came six hours later: Checked the Current Firmware Version : Log in

"Thank you. This will be fixed in V200R020. Your TAC case number is linked below."

Below was a new link—the beginning of another story.

Moral: In networking, the weakest link is rarely the cable. It’s the gap between what the documentation says and what the hardware actually needs. And sometimes, the strongest upgrade link is the one you build yourself, from experience.

Huawei switch firmware and patches can be downloaded directly from the official Huawei Enterprise Support Portal

. Accessing these files typically requires an enterprise or partner account; a standard guest account may have restricted download permissions. How to Find and Download Firmware

To find the correct firmware version for your specific device, follow these steps: Locate Your Model : Log in to the Huawei Support Site and navigate to Support > Software Download Select Product Series Enterprise Network > Switches , then select your specific series (e.g., S5700 Series Identify Versions

: Look for the target software version, usually formatted as VxxxRxxxCxx V200R019C10 Download Files System Software : The main image file ends in Patch Files : These fix specific bugs and end in Documentation : Always download the Upgrade Guide Release Notes

corresponding to your version to check for hardware compatibility and dependencies. Summary of Common Upgrade Commands

Once you have uploaded the files (via FTP, TFTP, or SCP) to the switch's flash memory, use these CLI commands to execute the upgrade: CLI Command Check Current Version display version Specify Software for Startup startup system-software Specify Patch for Startup startup patch Restart Device Do you need the specific firmware link

for a particular switch model (e.g., S5735, S6730), or would you like a step-by-step guide for transferring the files via TFTP/SCP? Upgrading a Switch - Huawei Technical Support

Part 4: Post-Upgrade Checklist

Check Interfaces: Are all ports up? display interface brief
Check VLANs: Did the VLAN configuration persist? display vlan
Check Routing: display ip routing-table
Clean Up: Once the new firmware is stable for a few days, you can delete the old .cc file from the flash memory to free up space.

Step 6: Verification

Once the switch is back online, log in and run:

display version

Confirm that the "VRP Version" matches the new firmware you installed.

Upgrade Steps via CLI

Here's a detailed walkthrough of the upgrade process using the CLI:

Connect to the switch: Establish a console or SSH connection to the switch.
Enter system view: Execute the system-view command.
Upload the firmware file: Use the upload file command to transfer the firmware file to the switch.
Start the upgrade: Execute the upgrade file command, specifying the firmware file name.
Follow the prompts: The switch will guide you through the upgrade process. Respond to any prompts as instructed.

Step 4: Set the Startup System Software

You must tell the switch to use the new file for the next boot, rather than the old one.

<Huawei> startup system-software flash:/S5735-V200R019C10SPC500.cc

If the switch requires a specific license or patch file associated with the system software, apply those as well before rebooting.
