A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : Cisco Systems UniDirectional Link Detection (UDLD) Protocol
Author(s) : M. Foschiano
Filename : draft-foschiano-udld-03.txt
Pages : 14
Date : 2007-4-9
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.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
