This one nearly made me tear my hair out. Option 43 is a vendor specific option that many vendors use to tell their devices the IP address of a server they need to access. Ubiquiti UniFi uses it and so does in this case Ruckus. I tried setting the value using a hex generator to no avail and after an email through a friend from a Ruckus engineer, we now have a tool!
Try THIS link to access the tool. I have not yet confirmed it works with Ubquiti UniFi but will try it next. It has the proper syntax for the raw option and Cisco as well. I think it likely will. Enjoy!
