Internet Engineering Task Force (IETF) D. Mohan, Ed. Request for Comments: 7023 Nortel Networks Category: Standards Track N. Bitar, Ed. ISSN: 2070-1721 Verizon A. Sajassi, Ed. Cisco S. Delord Alcatel-Lucent P. Niger France Telecom R. Qiu Juniper October 2013 MPLS and Ethernet Operations, Administration, and Maintenance (OAM) Interworking Abstract This document specifies the mapping of defect states between Ethernet Attachment Circuits (ACs) and associated Ethernet pseudowires (PWs) connected in accordance with the Pseudowire Emulation Edge-to-Edge (PWE3) architecture to realize an end-to-end emulated Ethernet service. It standardizes the behavior of Provider Edges (PEs) with respect to Ethernet PW and AC defects. Status of This Memo This is an Internet Standards Track document.
