Here's an example output of a Huawei switch firmware upgrade:
Before starting the upgrade process, make sure you:
startup system-software S5735-S-V200R021C00SPC100.cc Use code with caution.
Check if your current version requires an intermediate "bridge" version upgrade before moving to the target release. Check Hardware and Software Compatibility
A successful upgrade requires careful planning. Complete these steps before touching the production environment: Huawei Switch Firmware Upgrade
Open a web browser, enter the management IP address of your Huawei switch, and log in with your administrative credentials.
Firmware upgrades on Huawei switches are critical for security patches, bug fixes, and feature enhancements. This paper outlines a standardized methodology for upgrading Huawei switch firmware (VRP system software). It emphasizes pre-upgrade assessment, safe upgrade paths, fallback mechanisms, and post-upgrade validation to minimize downtime and risk.

Firmware upgrades require a system reboot, which will disrupt network traffic passing through the switch. Schedule the upgrade during low-traffic periods (e.g., weekends or late nights) and notify all affected stakeholders well in advance. 2. Pre-Upgrade Preparations Here's an example output of a Huawei switch
The switch will take several minutes to decompress the image and boot up. Once it responds to pings or console input, log back in to perform verification.
Ensure the switch can reach your management PC or file server.
You can transfer the firmware via TFTP, FTP, or SFTP. Setting up the switch as an FTP client connecting to an external FTP server is generally the most reliable method for large files. Step 2: Transfer the Firmware File to the Switch
Access Huawei Support and search for your specific model. It emphasizes pre-upgrade assessment
Ensure your specific switch model supports the target software version. Upgrading an end-of-life (EOL) switch to unsupported firmware can cause boot loops or permanent hardware failure. Verify system requirements, including minimum memory (RAM) and flash storage space. Schedule a Maintenance Window
Using SFTP is highly recommended over FTP or TFTP to protect administrative credentials during the file transfer process. Upgrading a Switch - Huawei Technical Support

If the upgrade file fails to copy, double-check hidden files or logs ( logfile/ ) that might be clogging the flash drive.
Download the .cc file from the Huawei Support portal. Integrity: Verify the software package checksum (MD5/SHA). 🚀 The Upgrade Process 1. Transfer the Firmware
Log in to the switch via SSH or console and execute the following commands to assess the current state:
