Hello, I have a P2100 switch – currently if I disable PoE to a specific port, the PoE re-enables itself after a period of time, while still reporting PoE is disabled on both the Dashboard popup menu and the PoE sub-menu.  I have tried factory reset, and switching PoE from auto to manual (and back) – makes no difference.  Any advice gratefully received.  Edit: I have regressed the firmware to 2.9.5 and the problem has not repeated itself so far.  Looks like a glitch in firmware 2.9.7.
