Hello Nancy,
You will need an ip address for the radius server. When you speicify the
radius-server host command you have to specify a host name or ip
address.

Sincerely,
Matijevic

1) Dont configure radius server, it will not be found and next option
will be taken.
2) Which ever is the last command router will take that
 
Dont forget to configure you siwtcport for dot1x

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
