Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet

Abstract

   The iSNS (Internet Storage Name Service) protocol provides storage
   name service functionality on an IP network that is being used for
   iSCSI (Internet Small Computer System Interface) or iFCP (Internet
   Fibre Channel Protocol) storage.  This document provides a mechanism
   to monitor multiple iSNS Servers, including information about
   registered objects in an iSNS Server.

1.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

2.  Introduction

   The iSNS protocol, as described in RFC 4171 [RFC4171], can be used by
   IP-based storage devices for dynamic registration and discovery of
   other storage devices in the network.  It has the capability to group
   devices into storage Discovery Domains, and Discovery Domains into
   Discovery Domain Sets.  The iSNS MIB is designed to allow Simple
   Network Management Protocol (SNMP) to be used to monitor iSNS servers
   supporting iSCSI [RFC3720] and iFCP [RFC4172].
