Ballot Text

Technical Summary

  This document describes a Cisco Systems protocol that can be used to
  detect and disable unidirectional Ethernet fiber or copper links
  caused for instance by mis-wiring of fiber strands, interface
  malfunctions, media converters' faults, etc.  It operates at Layer 2
  in conjunction with IEEE 802.3's existing Layer 1 fault detection
  mechanisms.

  This document explains the protocol objectives and applications,
  illustrates the specific premises the protocol was based upon and
  describes the protocol architecture and related deployment issues, to
  serve as a possible base for future standardization.

Working Group Summary

  This document is not the product of any IETF Working Group.  It was
  submitted directly to the RFC Editor by the authors.

Protocol Quality

  This document was reviewed by Joel Halpern and by the RFC Editor.

  At the request of the RFC Editor, the author changed the title and
  Abstract to make clear that this is a Cisco protocol, not an IETF
  product.
