Abstract

   This memo defines Management Information Bases (MIBs) for performing
   remote ping, traceroute and lookup operations at a remote host.  When
   managing a network it is useful to be able to initiate and retrieve
   the results of ping or traceroute operations when performed at a
   remote host.  A Lookup capability is defined in order to enable
   resolving of either an IP address to an DNS name or an DNS name to an
   IP address at a remote host.

   Currently, there are several enterprise-specific MIBs for performing
   remote ping or traceroute operations.  The purpose of this memo is to
   define a standards-based solution to enable interoperability.

1.0  Introduction

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119, reference
   [13].

   This document is a product of the Distributed Management (DISMAN)
   Working Group.  Its purpose is to define standards-based MIB modules
   for performing specific remote operations.  The remote operations
   defined by this document consist of the ping, traceroute and lookup
   functions.

   Ping and traceroute are two very useful functions for managing
   networks.  Ping is typically used to determine if a path exists
   between two hosts while traceroute shows an actual path.  Ping is
   usually implemented using the Internet Control Message Protocol
   (ICMP) "ECHO" facility.  It is also possible to implement a ping
   capability using alternate methods, some of which are:

   o   Using the UDP echo port (7), if supported.

       This is defined by RFC 862 [2].

   o   Timing an SNMP query.

   o   Timing a TCP connect attempt.

   In general, almost any request/response flow can be used to generate
   a round-trip time.  Often many of the non-ICMP ECHO facility methods
   stand a better chance of yielding a good response (not timing out for
