Hi!
This is not a FreeRADIUS question, it is a NAS question and whether your NAS supports VLAN *names* rather than just numbers.
I'm looking for a way to work with switches that do not support VLAN Names, and therefore I believe it is a free radius question. E.g. It would be possible for me to create a table with the VLAN IDs and the NAS IPs, so that freeradius could match them and send the correct VLAN ID, but I don't know how to use the NAS IP for such an lookup. Or maybe there is a better way to do it.
For the record, Cisco switches do support the use of names (if you have put it in your VLAN database), and their thick and thin AP's do too. YMMV with other venduhs though. To be honest, the time it took you to send this email, you could have actually tested it on your equipment...*sigh*.
I don't know the vendor of the switches so far as it is a running "public tendering procedure" (hope that's the correct English term for it) where I was not able to require it as MUST feature, but I need to make the planning for migration and implementation of dynamic VLANs now. ;-( Robert
