Use the FTP client from the switch to transfer the .cc and .pat files from your server. Ensure you are in the correct directory (e.g., flash:/ ).
Note: If the switch is operating in a stack (i.e., multiple switches joined via iStack), use the startup system-software filename.cc all command to apply the image to all member switches simultaneously. 2. Specify the New Patch File (If applicable)
Huawei switches usually act as a client or server to receive the new system software.
The switch will automatically boot with the new firmware. Huawei Switch Firmware Upgrade
Back up the configuration file using copy vrpcfg.zip tftp://[server_ip]/vrpcfg_backup.zip .
Complete Guide to Huawei Switch Firmware Upgrade Upgrading the firmware on a Huawei switch ensures network security, patches software vulnerabilities, and unlocks new enterprise features. This technical guide outlines the end-to-end process for upgrading Huawei VRP (Versatile Routing Platform) campus and datacenter switches. Pre-Upgrade Preparation
If the switch encounters a critical error loading the new firmware, Huawei switches will automatically roll back to the previous stable software image via the backup boot container. If this happens, connect a physical console cable to analyze the boot logs. Use the FTP client from the switch to transfer the
A mismatch between the firmware and hardware is a common cause of failure. Ensure the new firmware version explicitly supports your switch model (e.g., S5700-LI series requires specific files). Pay close attention to the feature set, such as "LI" (Lite Software Edition) or "EI" (Enhanced Edition) in the model number.
Once the system software is safely in the flash memory, instruct the switch to use this new file during the next boot sequence. Step 1: Configure the Boot Image
Calculate the MD5 or SHA256 checksum of the downloaded .cc file on your local machine. Back up the configuration file using copy vrpcfg
Always create a restore point before making structural changes. Export your current configuration file ( .cfg or .zip ) and the existing system software to an external server. save Use code with caution. 3. Preparing the File Transfer Environment
Huawei provides several upgrade methods. CLI commands are universally compatible, the web interface offers a visual alternative, Smart Upgrade automates the process, and BootLoad is for emergency recovery.
Disable local software firewalls; explicitly type binary in the FTP prompt before transfer.
Save your current running configuration one last time to prevent configuration data loss, then issue the reboot command.
