802.1x multiple VLANs assignments via RADIUS

Hey everyone,

We recently set up a dynamic VLAN assignment using RADIUS authentication on a M4100 switch, and tough it work well when we only specify one VLAN, we wondered if it was possible to specify multiples ones using the Tunnel-Private-Group-Id attribute.

After some research it appeared to be up to the NAS's type, to wether or not accept some syntax specifying multiple VLAN. ( http://freeradius.1045715.n5.nabble.com/Multiple-VLAN-value-per-user-td5747794.html )

For example, on a Foundry/Brocade/Ruckus ICX/Arris, you would set it up like this :

Tunnel-Private-Group-Id = "t:101;t:102;t:103;t:555;t:workstations"

So my question is, would it be possible to do the same thing on a M4100 ? but using a different syntax ? so far i havn't been able to make it work.

I'll appreciate your help, thanks in advance,

Vincent.
