Upgrading ArubaOS from a USB port

If you have a small (less than 8 GB) USB drive available, upgrading AOS can be done via the USB port on a wireless controller. For the USB’s file system, FAT32 is an option for Windows users.

After booting into CPBoot (the second boot prompt)

#start the usb port

usb start 1

#check if usb port is reading

usb dev
# to check if the file system is readable..
dir 1
# ex. upgrade command
upgrade 0:0 1:1 Arubaimage/ArubaOS_72xx_6.4.4.4_53338
