What is power over Ethernet (PoE)?
Power over Ethernet (PoE) allows the LAN switching infrastructure to provide power to an endpoint, called a powered device, over a copper Ethernet cable. The following types of end points can be powered through PoE:
What does a Poe display do?
Displays PoE status for an interface on a switch. Displays the PoE consumption for an interface. Displays the PoE states and priorities for an interface. Displays the available system power and the inline power of the interfaces.
How do I enable the timer to recover from Poe error-disabled state?
You can also enable the timer to recover from the PoE error-disabled state by using the errdisable recovery cause inline-power interval interval global configuration command. power inline police action errdisable : Turns off power to the port if the real-time power consumption exceeds the maximum power allocation on the port.
What protocols & standards support Poe?
The device uses the following protocols and standards to support PoE: Cisco Discovery Protocol (CDP) with power consumption: The powered device notifies the device of the amount of power it is consuming. The device does not reply to the power-consumption messages. The device can only supply power to or remove power from the PoE port.
What is Poe consumption?
consumption : Sets the PoE consumption (in mW) of the powered device connected to a specific interface. The power consumption can range from 4000 to 90000 mW. To re-enable the automatic adjustment of consumption, either use the no keyword or specify 60000 mW.
How do I enable error detection for a Poe error-disabled cause?
You can enable error detection for the PoE error-disabled cause by using the errdisable detect cause inline-power global configuration command. You can also enable the timer to recover from the PoE error-disabled state by using the errdisable recovery cause inline-power interval interval global configuration command.
