            Probing IP Interfaces By Vendor Specific Identifiers
                  draft-nayak-intarea-probe-by-vfi-01

Abstract

   This document enhances the PROBE diagnostic tool so that it can
   identify the probed interface by Vendor Specific Identifiers. 
   In order to achieve that goal, this document also extends the 
   Interface Identification Object.  The Interface Identification 
   Object is an ICMP Extension Object class.

1.  Problem Statement

   PROBE [RFC8335] is a diagnostic tool that can be used to query the
   status of an interface.  PROBE sends an ICMP Extended Echo Request
   message to a proxy interface.  The ICMP Extended Echo Request message
   contains an ICMP Extension Structure and the ICMP Extension Structure
   contains an Interface Identification Object.  The Interface
   Identification Object identifies the probed interface by name,
   ifIndex or address.

   When the proxy interface receives the ICMP Extended Echo Request, the
   node upon which it resides executes access control procedures as per 
   [RFC8335] security considerations.  If access is granted, the node 
   determines the status of the probed interface and returns an ICMP 
   Extended Echo Reply message.  The ICMP Extended Echo Reply indicates
   the status of the probed interface.

   Virtualized instance of the network adapter are created out of a 
   Network Interface Card to enable efficient sharing of Network 
   Interface Card in a virtualization environment. These Virtualized 
   instances of the network adapter are implemented in the hardware and
   assigned a Vendor Specific Identifier to uniquely identify the 
   Virtualized instance of the network adapter.

   This document enhances the PROBE so that it can identify the probed
   interface by Vendor Specific Identifiers. This probe type is 
   necessary when none of the other probe types of PROBE (i.e., probe
