Need help getting Dynamic VLAN Assignment working with RADIUS and Dell PowerConnect 3524

Question

I'm attempting to get Dynamic VLAN Assignment working on a number of Dell PowerConnect 3524 switches.

I've got a two RADIUS servers, both of which I've proved to be working using radtest on Linux.

One of the servers (Priority 0) is hosted on the network management VLAN (TekRADIUS running on Windows), and the second (Priority 1) is located on another VLAN (FreeRADIUS on Linux).

I can't seem to convince the switches to actually perform an authentication against either of the RADIUS servers however.

Network Comms between the switch and RADIUS servers has been proven using ping from the switch CLI.

My switch configuration is as follows, can anyone spot anything I've missed?

interface range ethernet all
spanning-tree portfast

interface range ethernet e(1-24)
dot1x multiple-hosts authentication

Answer 1

I've managed to resolve this now (or mostly). The ports are being correctly assigned to VLANs as a result of RADIUS authentication, however for some reason after the device gets assigned an IP address from our DHCP server, no other traffic is forwarded.

I've probably just got my VLAN routing wrong, or I'm not correctly passing VLAN traffic on the trunk ports.

For anyone else finding this via google my (mostly) working config is as follow:
