Hi, Ron,

Scanning through the document, please find a couple of quick questions and comments:

  1.  Have you considered an approach as in draft-shen-traceroute-ping-ext<https://tools.ietf.org/html/draft-shen-traceroute-ping-ext>, which is more general and has potentially better changes of success (working on ICMP Echo but also UDP Ping and TCP Ping)?
  2.  What is the reason for the “by address” option? The main use case of this functionality as defined seems to be unnumbered / link-locals. And if there’s a need for “by address”, a proxy ping is more general.
  3.  The “by ifIndex” option is essentially pulling operational state out of a box — what’s the line between an SNMP get or reading operational info on /interfaces-state/interface/oper-status vs. getting other node operational info (get CPU%)? And in this context, what’s the Auth model?

Thanks!

— Carlos.

Subject: New Version Notification for draft-bonica-intarea-eping-00.txt


A new version of I-D, draft-bonica-intarea-eping-00.txt has been successfully submitted by Ron Bonica and posted to the IETF repository.

Name: draft-bonica-intarea-eping
Revision: 00
Title: Extended Ping (eping)
Document date: 2016-06-23
Group: Individual Submission
Pages: 12
URL:            https://www.ietf.org/internet-drafts/draft-bonica-intarea-eping-00.txt
Status:         https://datatracker.ietf.org/doc/draft-bonica-intarea-eping/
Htmlized:       https://tools.ietf.org/html/draft-bonica-intarea-eping-00


Abstract:
  This document describes a new diagnostic tool called Extended Ping
  (eping).  Network operators execute eping to determine whether a
  remote interface is active.  In this respect, eping is similar to
  ping.  Eping differs from ping in that it does not require network
  reachability between itself and remote interface whose status is
  being queried.

  Eping relies on two new ICMP messages, called Extended Echo and
  Extended Echo Reply.  Both ICMP messages are defined herein.





Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org>.
