Hello. I have a problem enabling 802.1x authentication. I have a 3750 switch. I enabled 802.1x authentication over a port on which a client is attached. this is my configuration: aaa new-model aaa authentication dot1x default group radius interface GigabitEthernet1/0/9 no ip address no mdix auto dot1x port-control auto radius-server host 192.84.x.y auth-port 1812 acct-port 1813 key prova123 but nothing happens.... I have windowsXP as client. I also forced dot1x port-control force-unauthorized to disable client to access the network but client can still access the network without being filtered out because on hte port 9. anyone has some hints ?? thanks Rick
