I have a new C9800-CL and I've added a Radius server for 802.1x authentication.  I wanted to check some settings in the CLI and now I'm not able to get to the enabled prompt.  It prompts for login but when I do login I get "% Error in authentication....

How do you predownload the AP image from a 5508 to 9800 ? I've made the 9800 the secondary controller but the primary image doesn't update.
