Cloudpath/Radius server with vlan pooling, can it be done?

We will be on-boarding staff, student and guest personal devices using Cloudpath. We currently have over 2,500 student personal devices and I would rather not place them all in a single vlan which would create a lot of broadcast traffic.

I want to create a vlan pool consisting of eight /23 vlans. A /23 vlan yields about 500 IP addresses with eight of them giving me 4,000 addresses I can hand out to student personal devices. A /23 is nice and small to cut down on broadcast traffic and keep performance optimal. I then want students to authenticate via Cloudpath and be placed in this vlan pool.

This can already be done with Aruba

Can I do this with Cloudpath and Ruckus?

You could use Loopback interfaces:
interface GigabitEthernet0/0.101
description student WiFi
encapsulation dot1Q 101
ip unnumbered Loopback10
ip helper-address 10.10.10.1
no ip redirects
no ip unreachables
no ip proxy-arp
ip policy route-map cloudpath
no cdp enable
and repeat for as many VLANs as you are using

What you have described is a bit out of my area of expertise. I am bit foggy on the interaction between a radius server and the Ruckus controller works but this is my best guess. I believe a radius server can easily return an attribute that indicates that this is a student personal device trying to authenticate to the network. What I am not sure is possible is the Ruckus controller taking that attribute and placing that device/student in a vlan pool as defined in the controller. The attribute can be used to place the student/device in a single vlan but I want the student/device placed in a vlan pool.

Exactly how would using a loopback interface help in this regard?
