Unable to issue dot1x port control

Hey guys,

I don't have a switch to work on right now and I'm trying to go through some switch labs. I attempted to issue the following sequence of configurations:


Switch(config)#aaa new-model
Switch(config)#radius-server host x.x.x.x key yadayada
Switch(config)#aaa authentication dot1x default group radius Server for authentication
Switch(config)#dot1x system-auth-control
Switch(config)#interface range fast 0/1 - 24
Switch(config-if-range)#dot1x port-control auto

my issue is that it wont take the configuration. I'm using a virtual rack and I'm really wondering if I'm doing this right. I"m using Version 12.2(35)SE5 on a 3560

Thanks,

I'm trying to configure this switch to have users authenticate to a Radius Server.

I figured it out. You need to use:
switchport mode access, first and then dot1x will be available.

Another question. Do I have configure the following on every switch? I mean, core switches included?

Switch(config)#aaa new-model
Switch(config)#radius-server host x.x.x.x key yadayada
Switch(config)#aaa authentication dot1x default group radius Server for authentication
Switch(config)#dot1x system-auth-control
