Huawei Switch Firmware Upgrade Official

Huawei switch firmware upgrades utilize the Huawei Versatile Routing Platform (VRP)

to provide flexible management for system software and patches . These upgrades typically involve system software (ending in ) for major version changes and (ending in ) for specific bug fixes or security updates. Key Upgrade Features Smart Upgrade:

A high-efficiency feature that allows the switch to automatically connect to the Huawei Online Upgrade Platform (HOUP)

via HTTPS. It checks for the recommended version, downloads the necessary files, and performs the upgrade with minimal manual intervention. Smooth Upgrade (Stacking): Specifically for stacked switches Huawei Switch Firmware Upgrade

, this feature divides member switches into active and backup areas. While one area is being upgraded, the other continues to handle traffic, significantly reducing service interruption. Verification Mechanisms: Huawei provides digital signature files

(in PGP or CMS format) to ensure software integrity. The switch can perform automatic signature verification during the deployment phase to prevent the use of tampered files. Patch Management:

Patches can be installed, uninstalled, or activated without a full system reboot in many cases, allowing for rapid security fixes with minimal downtime. Multiple File Transfer Options: Supports various protocols including FTP, TFTP, and SCP Huawei switch firmware upgrades utilize the Huawei Versatile

for uploading firmware files to the device's flash memory before the upgrade process begins.

Step 1: Transfer the Firmware File to the Switch

Use any of these methods (example uses TFTP for simplicity):

<Huawei> tftp 192.168.1.100 get S5720-V200R023C00SPC500.cc

Verify file transfer:

<Huawei> dir flash:/

Part 2: Pre-Upgrade Checklist (The "Golden Hour")

A rushed upgrade is the leading cause of a "bricked" switch. Dedicate 60 minutes to preparation.

5. Schedule a Maintenance Window

Even with ISSU (In-Service Software Upgrade), reserve a 2-hour window. ISSU on Huawei switches is reliable only for minor revisions (e.g., R011 to R015). Major revisions require a full reboot.

4. Staging Environment (If Possible)

If you have a lab switch of the same model, perform the upgrade there first. Observe memory usage and interface behavior. Step 1: Transfer the Firmware File to the

Final Recommendation

Test on a non‑production switch first.
Read release notes – especially for V200R010 and later, as license handling changed.
Use ISSU (In‑Service Software Upgrade) on stackable models to minimize downtime:
```
<Huawei> issu start filename flash:/new-firmware.cc
```

Step 2: Verify the Current Firmware Version

Use the display version command to verify the current firmware version:

< Huawei > display version
