Abstract
Systems, methods, and related technologies for device identification and policy enforcement using Power over Ethernet (PoE) are described. In certain aspects, a communication that originates from a Power over Ethernet (PoE) enabled device can be received. The communication can be processed to determine a characteristic of the device. An action can be initiated based on the characteristic.
Claims19
A method comprising:
- receiving a communication that originates from a Power over Ethernet (PoE) enabled device, wherein the PoE enabled device receives electrical power from an Ethernet port;
- monitoring an amount of power consumed by the PoE enabled device;
- processing, by a processing device, the communication and the amount of power consumed by the PoE enabled device to determine one or more characteristics of the PoE enabled device, wherein the one or more characteristics comprise a type of the PoE enabled device;
- and
- initiating a network access policy enforcement action based on the determined one or more characteristics of the PoE enabled device and the amount of power consumed by the PoE enabled device.
A system comprising:
- a memory;
- and
- a processing device, operatively coupled to the memory, to:
- monitor an amount of power consumed by a Power over Ethernet (PoE) enabled device, wherein the PoE enabled device receives electrical power via an Ethernet port;
- receive a communication that originates from the PoE enabled device;
- process the communication and the amount of power consumed by the PoE enabled device to determine a type of the PoE enabled device and to identify a deviation from a power consumption pattern associated with the PoE enabled device;
- and
- initiate a network access policy enforcement action based on the type of the PoE enabled device and the deviation from the power consumption pattern associated with the PoE enabled device.
A non-transitory computer readable medium having instructions encoded thereon that, when executed by a processing device, cause the processing device to:
- receive a communication that originates from a Power over Ethernet (PoE) enabled device, the communication comprising information pertaining to an amount of power consumed by the PoE enabled device, wherein the PoE enabled device receives electrical power via an Ethernet port;
- process, by the processing device, the communication and the amount of power consumed by the PoE enabled device to determine one or more characteristics of the PoE enabled device, wherein the one or more characteristics comprise a type of the PoE enabled device;
- and
- initiate a network access policy enforcement action based on the characteristic and the amount of power consumed by the PoE enabled device.
