I recently upgraded one of my Catalyst 3850 48P switches to 16.2.2. The upgrade went as expected and I was able to login to the HTTP site for the switch and configure Application Visibility and Control, suddenly the switch rebooted and I am not longer able to login to the switch via HTTP with either local or AAA credentials. I have entered the ip http authentication local and ip http authentication aaa commands seprately to see if this resolved the issue without any success. Has anyone else experienced this or have I missed something in the configuration?
