I need some help with detecting if a MikroTik device is being powered via PoE-IN or not.
As far as I can see, any device with PoE-OUT supports
/interface ethernet poe print
Any device with PoE-IN but no PoE-OUT will just throw
bad command name poe
My conclusion is that I cannot detect remotely if a device is being powered via PoE-IN or not, either via SSH commands or WinBox.
I would love somebody to tell me I am wrong and provide a solution.
Generally it’s not possible to determine power source, used by MT device. This includes all power sources (barell jacks, PoE, terminal blocks). If device does report supply voltage, and voltages, provided to different power inputs are distinctively different, then checking this status helps to determine the power input in use.
