802.1x with Radius!

Hi,

I am trying to authenticate a PC against a RADIUS authentication server, without configuring an IP address for the RADIUS server. The PC is connected to a 3550. When the PC first connects to the 3550, it begins in an unauthorized state which allows only the authentication packets to flow between the PC and the authenticator...after I enabled aaa, I created an authentication list

a)Switch(config)# aaa authentication dot1x default group radius none ------<-------contacts the server, if the server doesn't respond it will allow the user with no authentication

bSwitch(config)#aaa authentication dot1x default local none---------<-----use no authentication

 

Two questions:

1)The doc CD specifies that if we use a group radius, we must configure a RADIUS server by using the radius-server host command which requires an IP address...how can I meet the requirements without an IP address nor DNS.

2)Does it matter the order in which these commands are entered...in other words if I'd entered b before a, does it mean that the switch will never forward these packets to a server?

Anyone can clarify this ? Thanks a lot
