Good morning,
Is anyone else running 16.12.3a IOS on 3850 switches?
Here is an issue we are facing but I can not find any documentation of a bug in this code and its still recommended as the code to go to...
Issue: POE Stops functioning on random ports but works on others. POE will not work for Avaya phones, cameras, cisco phones, or Cisco AP's ( 3602,3702,3802).
Work around: Reboot switch, downgrade, or find a port that will provide POE.
We began upgrading and testing on several stacks for a month or 2 with no issues prior to deploying to approximately 30 stacks of 3850's. After we did a mass deployment we began to see POE issues on switches that seem to be triggered when removing or adding a POE device. Once the condition has been triggered it will not go away until rebooted or downgraded. Logs will state " Controller port error, interface x/x/x, power given, but machine power good wait timer timed out.
I have found similar issues or bugs in older codes, have we regressed?
