Huawei Switch Firmware Upgrade Link ((exclusive)) May 2026
The primary destination for Huawei switch firmware is the Huawei Enterprise Support Portal. Accessing these files generally requires an Enterprise account with valid product permissions or a service contract associated with the device. Where to Find Upgrade Links
You can locate specific firmware by following these steps on the Huawei Technical Support site: Navigate to Products: Select Enterprise Network > Switches. Select Your Model: Choose your specific series (e.g., , or CloudEngine series).
Software Download Tab: Click this tab to see available versions.
Release Selection: Choose the recommended version (often marked with a shield icon or "Custom") to view the download links for the system software (.cc) and patch files (.pat). Review: Why Upgrade?
Upgrading your switch firmware is a critical maintenance task for several reasons:
Security Patches: Protects your network against newly discovered vulnerabilities.
Performance Stability: Fixes bugs that cause unexpected reboots or packet loss.
New Features: Adds support for newer protocols, improved CLI commands, or enhanced web management interfaces. Critical Considerations
Permission Required: Unlike consumer hardware, Huawei enterprise firmware is typically not public. You must register an account and link it to your hardware's serial number (SN) or a support contract to see download links. huawei switch firmware upgrade link
Compatibility: Always check the Release Notes and Upgrade Guide provided on the same download page. These documents specify the "Upgrade Path" (the minimum version required to jump to the new one) and potential hardware limitations.
Preparation: Before starting, ensure you have a backup of the current configuration and a reliable connection (TFTP, FTP, or SFTP) to transfer the file to the switch's flash memory. Upgrading a Switch - Huawei Technical Support
Upgrading Huawei switch firmware (the system software file with a .cc extension and patches with a .pat extension) is a critical maintenance procedure typically handled through the Huawei Enterprise Support Website. Official Download Links and Portals
To obtain the correct firmware, use the official portals based on your user type:
Enterprise Users: Access the Huawei Enterprise Software Download Portal.
Navigate to Enterprise Network > Switches, select your specific series (e.g., S5700 series), and go to the Software Download tab.
Carrier Users: Log in to the Huawei Carrier Support Site. Search for your specific switch model to enter the dedicated product page.
eKit Users: Small and medium-sized enterprise (SME) users can find relevant firmware on the Huawei eKit Switches Page. Core Upgrade Methods The primary destination for Huawei switch firmware is
There are four primary ways to perform a firmware upgrade on Huawei Switches: Upgrading a Switch - Huawei Technical Support
Upgrading the firmware of a Huawei switch is a critical maintenance task that ensures network security, stability, and access to new features. The primary official resource for these updates is the Huawei Enterprise Support Website
, where users can download both the system software and detailed, version-specific upgrade guides. Obtaining Firmware and Guides
To secure the correct firmware, administrators must navigate the support portal using a verified corporate or partner account. The typical path involves: Identification : Selecting the specific product series (e.g., Campus Switch S5700 ) and model
: Choosing the required version—often identified by a "V and R" version string such as V200R021C00. : Retrieving the system software ( file) and, if applicable, the public patch file ( Verification
: Downloading the CMS signature files to verify the integrity of the software package before installation. Methods of Upgrade
Depending on the network scale and administrative preference, several methods are available:

files) from the official Huawei support portal. The process generally involves downloading the files to a local PC, transferring them to the switch, and configuring the switch to boot from the new software.

Step 2: Prepare for the Upgrade
- Connect to the Switch: Use a console cable or establish an SSH connection to the switch.
- Login and Backup Configuration: Log in to the switch, and immediately back up your configuration.

- Version: Recommended is typically the latest V200R023 or V200R021 (stable long-term support)
Post-Upgrade Checklist
After completing the upgrade:
- Verify the firmware version: Use the
display versioncommand to confirm the new firmware version. - Restore your configuration: If necessary, restore your configuration from the backup file created earlier.
- Test network services: Verify that network services are functioning as expected.
2. Access the Enterprise Support portal
- Log in with your Huawei partner/enterprise account.
- If you lack a contract, you may only see security advisories, not download links.
Step 2: Transfer to the Switch
Connect to the switch via console or SSH. Use the following command to copy from your TFTP server:
<Huawei> tftp 192.168.1.100 get S5720-V200R021C00SPC100.cc
Or via FTP:
<Huawei> ftp 192.168.1.100
[ftp] get S5720-V200R021C00SPC100.cc
✅ What Works Well
- Structured Upgrade Path – Huawei provides clear “upgrade path” documents. Skipping versions isn’t allowed; you must follow their version chain, which prevents configuration corruption.
- Dual Boot Banks – Most Huawei switches have two flash areas (e.g.,
flash:/andflash:/backup/), allowing a fallback if the new firmware fails to load. This is a lifesaver during remote upgrades. - Minimal Downtime – Using
startup system-softwareand reloading takes 5–10 minutes. For stacked switches, ISSU (In-Service Software Upgrade) can upgrade without full outage.
The Unconventional Solution
He remembered an old Huawei TAC trick: The In-Service Firmware Link via USB Recovery Mode. There was a hidden recovery partition accessible only through a specific console command sequence:
<CE12800> system-view
[~CE12800] upgrade fabric-usb recovery enable
[~CE12800] set boot-loader usb0:/CE12800_V200R019C10SPC800.cc usb0:/CE12800_V200R019C10SPC800.web.7z ?
Most engineers never saw the recovery enable option. But Lin Wei had once debugged a bricked switch in a rural substation. That experience taught him that Huawei’s firmware upgrade link wasn’t just a URL—it was a concept. A chain of trust from the supplier’s server → your download → the switch’s internal bus → the ASIC drivers.
He copied the firmware to a clean USB drive, booted the standby module from USB, and executed a cross-version delta upgrade—skipping three intermediate patches. The switch’s internal integrity check flagged one incompatible I2C driver.
