Well, the standard suggestion, documented in the server docs, is to 
capture the output of:

radiusd -X

...on a working and failing system. Read the output, see if you can spot 
the problem. If not, post it here.

Don't use VMPS.

Seriously: the VMPS code in FR is great, but VMPS is ancient. If your 
switch supports it (and I'm sure it does) you should just use RADIUS and 
MAC-based VLANS (called MAB in Cisco-land) instead.
