Use of link layer discovery protocol-media endpoint discovery to avoid false legacy powered device detection in power over ethernet systems and networks

摘要

Described herein are systems, devices, techniques and products for minimizing disruption to network systems due to false detection of a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) as a Powered Device (PD). The disclosed systems, devices, techniques and products provide a way for a PSE to identify itself and avoid being detected as a legacy PD. The disclosed systems, devices, techniques and products further provide a way for a PSE to identify devices that do not require power from the PSE, such as another PSE or a device that is not a PD, and disable automatic PD detection, disable PoE, or otherwise prevent injection of power/current to the other device.
