Abstract:
Embodiments of the present disclosure provide systems and methods to enable a Power Source Equipment (PSE) and a Powered Device (PD) advertise their identity, capabilities, and neighbors by exchanging IEEE Standard 802.1AB Link Layer Discovery Protocol (LLDP) information in Ethernet frames. Each Ethernet frame contains one or more LLDP Data Units (LLDPDUs) corresponding to a sequence of type-length-value (TLV structure) structures. The PSEs and PDs utilize optional TLV Structures from among the one or more LLDPDUs to advertise their PoE capabilities.
