Hi my friend. Did you solve this problem?

Hello,   Do you solved this problem?  

Amjad,Help me, please. The configuration works in 3560 (Version 12.2(44)SE5), but not work in 6509 (Version 12.2(50r)SYS2). Do you know why?Thanks,Robertoaaa new-modelaaa group server radius net-managerserver x.x.x.xexitaaa authentication login defau...

I think this is a duo comunication (wired lan and wireless lan) from hosts. It's probably a host with two NICs (wired and wireless) and both are run. If you have a loop, the log would be the least of your problems.
