            Probing IP Interfaces By Virtual Function Index
                  draft-nayak-intarea-probe-by-vfi-00

Abstract

   This document enhances the PROBE diagnostic tool so that it can
   identify the probed interface by Virtual Function Index.  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.  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.

   This document enhances the PROBE so that it can identify the probed
   interface by Virtual Function Index (VFI) [SR-IOV].  In order to
   achieve that goal, this document extends the Interface Identification
   Object.  The Interface Identification Object is an ICMP Extension
   Object class.
