I am trying to get the Ascend NASs to switch to the secondary radius  
server when the primary has a failure condition.  I know that no  
response will cause that, but haven't been able to find any way to  
make the switch occur with the primary is not working properly.  Is  
there a particular value to send back that would cause the switch?
