We have standardized on 3850-48P (IOS-XE 03.06.04.E) switch stacks in our enterprise and recently we have been seeing problems where random ports (on various switch stacks) would cease to provide power to our Mitel VoIP sets, even though those ports still function when non-powered devices connect to them.
When this failure occurs, the following log entries appear.:
Nov 30 10:14:50.358 EST: %ILPOWER-7-DETECT: Interface Gi4/0/28: Power Device detected: Cisco PD
Nov 30 10:14:51.087 EST: %ILPOWER-5-IEEE_DISCONNECT: Interface Gi4/0/28: PD removed
Nov 30 10:14:51.089 EST: %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi4/0/28: Power Controller reports power Tstart error detected
I resolve the problem in by moving the device to another port on the switch stack. In this most recent case, I moved the phone to another port on the same switch in fact.
I also issued a "show power inline module 4" and the results are listed below:

I appreciate any suggestions anyone might have. I have seen a bug reported with symptoms similar, but not applicable to this switch or this code.
Thanks in advance.
