Upgrading a Huawei switch is a critical task for maintaining network security and stability. While the process typically involves manual file transfers via CLI or the web interface, the most interesting and modern feature for this task is Smart Upgrade. The Standout Feature: Smart Upgrade
Smart Upgrade is a "one-click" solution that connects your switch directly to the Huawei Online Upgrade Platform (HOUP) via the internet.
How it Works: The switch periodically sends its current version and serial number (ESN) to HOUP. The platform then recommends the optimal software package or patch based on Huawei's maintenance policies.
Key Benefit: It removes the need for manual downloads from support sites and complex file transfers. You can trigger the upgrade immediately through the CLI or web platform, and the switch handles the download and next-startup configuration automatically.
Safety: You can set emergency contact info (email/phone) in the configuration so Huawei can assist if an error occurs during the automated process. Standard CLI Upgrade Process
For environments without direct internet access, the traditional CLI method remains the standard procedure:
The server room was a hum of controlled chaos, a cathedral of blinking LEDs and the rhythmic whir of cooling fans. At the center of it all stood the core of the network: a stack of Huawei CloudEngine switches , the silent sentinels of the company’s data.
Leo, the lead network engineer, sat at his console, the blue light of the terminal reflecting in his glasses. Tonight was the night. The maintenance window had just opened, and it was time for a critical VRP (Versatile Routing Platform) firmware upgrade. Huawei Switch Firmware Upgrade
“Alright, let’s do this,” he muttered, more to the hardware than himself. Phase 1: The Ritual of Preparation
Leo began with the digital equivalent of a deep breath. He ran the command display version display patch-information
to confirm the current state. He knew the golden rule: never move forward without a way back. He initiated a full backup of the configuration file to the TFTP server. Next came the transfer. Using the command, he began moving the new
software package from his remote server to the switch’s flash memory. He watched the progress bar crawl across the screen, a tiny line of characters representing years of R&D and security patches. Phase 2: The Moment of Truth
Once the file transfer was complete, Leo performed a checksum. display software-package check
. If the hash didn't match, the whole operation would stop right here. The screen returned a "Passed." He typed the command that would change the switch's future: startup system-software Flash:/CE12800-V200R019C10SPC700.cc
The switch was staged. It knew what to do upon its next awakening. Phase 3: The Leap "Rebooting," Leo whispered, hitting the Enter key on
The "Active" lights on the switch faceplates flickered and then went dark. For a network engineer, this silence is the loudest sound in the world. Seconds turned into minutes. He pinged the management IP address—no response. He checked the console cable output, watching the bootloader initialize, decompressing the new image, and verifying the hardware integrity. Then, a flurry of green lights danced across the ports. The Awakening
The terminal surged back to life. Leo typed his credentials and issued the final command: display version
The screen blinked back the new version number. The patches were applied, the bugs were squashed, and the throughput was optimized. He checked the routing tables and the BGP neighbors—everything was peering perfectly.
Leo leaned back, the tension leaving his shoulders. Outside, the city was asleep, unaware that their digital lifelines had just been upgraded. He logged off, leaving the CloudEngine switches to continue their silent, high-speed vigil in the dark. to the story, or perhaps a step-by-step technical guide based on this scenario?
Upgrading firmware on a Huawei switch involves obtaining the correct system software ( file) and patch (
file), transferring them to the device, and configuring the switch to boot from the new version. Prerequisites & Preparation

Check Storage Space: Ensure the flash memory has enough space for the new files; delete unnecessary files if needed. Standard CLI Upgrade Method This is the most common method for operational switches. Transfer Files: Upload the new firmware ( ) and patch ( ) to the switch using FTP, TFTP, or SCP.
Set Startup Software: Tell the switch to use the new file for the next boot: startup system-software [filename].cc startup patch [filename].pat
Reboot: Execute the reboot command and confirm when prompted. Disclaimer: Firmware versions mentioned (e
Verify: After restart, run display version to confirm the target version is active. Alternative Upgrade Features Upgrading a Switch - Huawei Technical Support
Upgrading the firmware on Huawei switches—often referred to as updating the system software (typically a .cc file) and patches (.pat file)—is a critical maintenance task for enhancing device performance, fixing security vulnerabilities, and accessing new features. 1. Pre-Upgrade Checklist
Before starting, ensure you have completed these essential preparations: Upgrading a Switch - Huawei Technical Support
Upgrading the firmware on a Huawei enterprise switch is a critical maintenance task that ensures network stability, security, and access to new features. This process typically involves moving to a newer version of the Versatile Routing Platform (VRP) operating system. 1. Pre-Upgrade Preparation
Before starting, ensure you have the necessary files and access rights.
Identify Your Hardware: Check your switch model and current version using the display version command in the CLI.
Download Firmware: Log in to the Huawei Enterprise Support Portal to find the correct software package (typically a .cc file) and the corresponding Patch and Web Page files if applicable.
Release Notes: Always read the Upgrade Guide and Release Notes for your specific version to check for hardware compatibility or mandatory intermediate versions.
Backup: Save your current configuration using save and export it to an external server (FTP/TFTP/SFTP) to ensure a quick recovery if the upgrade fails. 2. Transferring the Firmware
Huawei switches usually act as a client or server to receive the new system software.
Establish Connectivity: Ensure the switch can reach your management PC or file server.
File Transfer: Use an SFTP or FTP client to upload the .cc system file to the switch's flash memory.
Command Example: sftp 192.168.1.100 get S5700-V200R021C00.cc 3. Setting the Boot File
Once the file is on the switch, you must instruct the system to use it for the next reboot.
Specify the New File: Use the startup system-software command. Command: startup system-software S5700-V200R021C00.cc
Verify the Setting: Run display startup to confirm that the "Next startup system software" points to the new file while the "Configured startup system software" remains the old version until the reboot. 4. Execution and Verification
Reboot: Execute the reboot command. Note that this will cause network downtime unless you are using a cluster (iStack) with a rolling upgrade strategy.
Post-Upgrade Check: Once the switch is back online, verify the new version: display version: Confirms the new VRP version is running.
display patch-information: Checks if any required hotfixes or patches are active. 5. Key Considerations Before starting the upgrade process
Storage Space: Firmware files can be large. Use dir to check flash memory and delete old, unused firmware files if necessary.
Patching: Huawei often releases "Cold" and "Hot" patches. Hot patches can be applied without a reboot, while cold patches require one.
Security: Using SFTP is highly recommended over FTP or TFTP to protect administrative credentials during the file transfer process. Upgrading a Switch - Huawei Technical Support
