Abstract

Systems and methods of propagating frame loss information by a node in an Ethernet network include detecting one or more of service unaware port discards and service aware port discards; determining statistics based on the one or more of service unaware discards and service aware port discards; and transmitting the determined statistics to a sender node through one of a Link Layer Discovery Protocol Data Unit (LLDPDU) and a Link Trace Message (LTM). The LLDPDU and the LTM can include an organization specific Type-Length-Value (TLV) with a TLV information string therein based on the determined statistics and cause of the one or more of service unaware discards and service aware port discards.
