I recently replaced a legacy 6513 with a 4510R+E running cat4500es8-universalk9.SPA.03.03.00.XO.151-1.XO.bin
Upon booting up a handful of workstations connected to the 4510 are unable to pull IP addresses. Once booted up, if you unplug and then plug the network cable back into workstation it pulls an IP address.
The config is pretty vanilla. The only thing I did that I wouldn't usually do was add this command "ip device tracking probe delay 5" to address this issue... https://supportforums.cisco.com/discussion/11621386/ise8021x-ip-conflict-0000 I get the same results even if I remove this command
Any suggestions?

Have you configured the ports, as it sounds like 'portfast' is not enabled?

Thanks for your input.
Portfast is configured globally. Just to be double certain I even configured it on the inteface.but it made no difference.
