Thanks for the follow-up.  I found that it wasn't a firmware issue, it was a reboot problem.  After rebooting the switch, 802.1x started working.  All ports are set to do Radius, it locked out all my ports when I rebooted.  Consoled in, updated a single port for management and we were off to the races.
I've gone through and attempted to setup RADIUS, but when i plug in a device, the switch never reaches out to my NPS server. Any help would be great. !System Software Version 6.7.1.17 ip address 192.168.19.8 255.255.255.0exitip default-gateway 192.168.19.1username "admin" password privilege 15 encrypted dot1x system-auth-control radius server source-ip 192.168.19.8 radius server auth 192.168.140.4 primary name "DC02" key 7 " " exit  interface Gi1/0/10no green-mode energy-detectno green-mode eeeswitchport mode generalswitchport general allowed vlan add 500 taggedswitchport access vlan 140authentication host-mode single-hostauthentication event fail action authorize vlan 100authentication periodicexit!
