Abstract
A network device and an adjacent network device may autonegotiate for utilization of an OSI layer 2 protocol for exchanging control information. The network device may generate and/or communicate to the adjacent network device, Ethernet frames comprising the control information based on the OSI layer 2 protocol. OSI layer 2 capabilities status and/or MAC address of the adjacent network device may be received and/or stored during auto-negotiation. An Ethertype and/or LLDP Ethertype may be set within the Ethernet frames to indicate utilization of the OSI layer 2 protocol. Payload within the Ethernet frames may be populated with control information that is encapsulated in a non-standardized or standardized discovery protocol frame and/or a LLDPDU. The control information may comprise device capabilities and/or communication parameters. Subsequent Ethernet frames comprising other content may be communicated to the adjacent network device based on the control information.
