Hi Everyone,

We are looking to amalgamate our 3 dot1x WLANs (employees/student/eduroam) into 
a single WLAN (eduroam). Behind the scenes we still need to authenticate and 
route clients to their respective network segment. So to achieve this we need 
to implement dynamic vlan redirects behind the scenes.

Eduroam users from other institutions will be sent out to eduroam to be handled 
appropriately

Authentication will be handled by ISE cluster, running 2.6.0.156
WLC - 5520 (pair) running 8.8.130.0

The process, from a high level should look something like this

  *   Staff/faculty will connect to our new single WLAN, namely Eduroam
  *   They will be caught by the appropriate policy and authenticated against 
AD, validating that they are staff/faculty
  *   Now they will be redirected to the appropriate VLAN


  *   Student will follow the same process, but will be validated that they are 
a student, and redirected to a different VLAN


  *   All others (externals) will be sent to an external RADIUS server for auth 
and then redirected to yet another different VLAN.

Currently unique policies exist for each of these processes, without the added 
complexities of the VLAN redirect. So my mission is to combine these, filtering 
each client to their auth point, and then upon receiving the authorization, 
assign the appropriate vlan tag, for IP assignment, prior to them getting 
on-net.

I've been unable to find any meaningful documentation around how to handle 
internal vs external radius redirection in this scenario.

So has anyone done this, and are they able to share their process, inclusive of 
vlan redirect?

Thanks
