Does anyone have a sample config for 802.1X on a 3750 using radius?

I have this problem too.

The key components of the config you will need are as follows:


! Radius Config

aaa new-model

aaa authentication dot1x default group radius
aaa authorization network default group radius
radius-server host YOUR_SERVER
radius-server key YOUR_KEY


! Enable dot1x globally

dot1x system-auth-control


! Configure the interfaces

interface range YOUR_RANGE_OF_ACCESS_PORTS

switchport

switchport mode access

switchport access vlan YOUR_ACCESS_VLAN

dot1x port-control auto

no shut




That is the basic config. You can also get into fancy features, like setting a guest access vlan for when 802.1x authentication fails, etc. The switch configuration is relatively simple. I actually run into more trouble with the radius configuration and configuration of clients for 802.1x pieces.
