[j-nsp] Radius - Static IP / ERX

[Gabriel Blanchard]

We have a very similar setup (for some obvious reason) and it works just 
fine. We use Framed-IP-Address. No other attributes are required.

What I suggest is that you try the "test aaa" command in the ERX and try 
to test the login that way from the console and see what's going on.
