Hello, first of all, sorry for my english. I want to ask, how can i use dot1x port-control here, i upgraded firmware to 6.6.3.0 version, but the behavior is the same like in previous versions (just commands are little bit different). In older models, there was another syntax and it works better. I have radius and auth vlan 200 and guest vlan 230. I set switchport acces vlan 200, auto port-control and dot1x guest vlan 230. In older switches (5548, 3524), when i connect to this port, i received firstly ip address from guest network 230, when the network verification on clients station is turned off or bad configured. When user set verify to good, radius sent OK answer and user retrieve ip adress from vlan 200. 

But when i connect to that port on new switches, i always have ip adress from vlan 200, also when i dont set authentication in my pc. (but i see in log, that the port is unauthorised, user cant acces anything, but ip in computer is good). This is weird, because user will never acces the guest vlan 230. Can you help me?
