(Internet Storage Name Service)
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
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

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.

Gibbons, et al. Standards Track [Page 2]RFC 4939 iSNS MIB July 20071. 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
