Enable the USB Firmware Upgrade Function by CLI Command
For security concerns, the function is disabled by default. The administrator needs
to enable the function by the following CLI command:
Router(config)# usb-storage update-firmware enable
Save the Firmware on the USB
There are two ways to create the firmware folder on the USB storage.
1 Follow the folder structure to create the firmware folder manually. It does not
matter if the letters of the folder name are capitalized or not. For example:
D:\usg210_dir\firmware
Create the Firmware Folder Manually: Root Directory\usg210_dir\firmware
2 Plug the USB storage to the device and the device will automatically create the
folder usg210_dir, which includes the following sub-folders. Save the .bin file to the
firmware folder.
