Hi Ben

I ran across this yesterday. I can't remember exactly what the problem 
with vconfig was since I ended up using the Red Hat recommended method.

This works perfectly and you can see exactly what's going on.

I think the problem with the vconfig was you need to do "vconfig add 
eth0.1 5" instead of "vconfig add eth0 5"
