Information technology — Fibre Channel — Part 372: Methodologies of interconnects-2 (FC-MI-2)

ISO/IEC 14165-372:2011(E) is intended to document interoperability behaviour for Fabric elements (i.e., E_Port, F_Port, FL_Port). It includes a wide range of issues such as link initialization, error detection, error recovery, fabric operation, management capabilities, and zoning. It serves as an implementation guide, whose primary objective is to maximize the likelihood of interoperability between conforming implementations. It specifies common methodologies for both Arbitrated Loop and Switched environments. The goal of this technical report is to facilitate interoperability between devices whether they are connected in a loop or Fabric topology.

FOREWORD
1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards. Their preparation is entrusted to technical
committees; any ISO and IEC member body interested in the subject dealt with may participate in this
preparatory work. International governmental and non-governmental organizations liaising with ISO and IEC
also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC
1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for
voting. Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
3) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has
representation from all interested IEC and ISO member bodies.
4) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the
technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held responsible for
the way in which they are used or for any misinterpretation by any end user.
5) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and
ISO/IEC publications transparently to the maximum extent possible in their national and regional publications.
Any divergence between any ISO/IECpublication and the corresponding national or regional publication
should be clearly indicated in the latter.
6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for
any equipment declared to be in conformity with an ISO/IEC publication.
7) All users should ensure that they have the latest edition of this publication.
8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual
experts and members of their technical committees and IEC or ISO member bodies for any personal injury,
property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC publication or
any other IEC, ISO or ISO/IEC publications.
9) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
10) Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 14165-372, which is a technical report, has been prepared by subcommittee 25: Interconnection
of information technology equipment, of ISO/IEC joint technical committee 1: Information technology.

1 Scope
This part of ISO/IEC 14165 is intended to document interoperability behavior for Fabric elements (i.e.,
E_Port, F_Port, FL_Port). This Technical Report includes a wide range of issues such as link initialization,
error detection, error recovery, Fabric operation, management capabilities, and zoning.
This Technical Report serves as an implementation guide, whose primary objective is to maximize the like-
lihood of interoperability between conforming implementations. This Technical Report prohibits or requires
some features that are in the referenced documents.
A second objective of this Technical Report is to simplify implementations and their associated documenta-
tion, testing, and support requirements. As a result there may be some optional features of the referenced
documents that are not mutually exclusive, but are prohibited or required for the purpose of this simplifica-
tion. Features that some but not all of the referenced documents require for compliance may be optional in
this report. Each specification of such an optional feature in this report identifies the referenced document
for which the feature is required.
Internal characteristics of conformant implementations are not defined by this Technical Report, but it incor-
porates features from the documents cited in clause 2.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated ref-
erences, only the edition cited applies. For undated references, the latest edition of the of the referenced
document (including any amendments) applies.
The provision of the referenced specification other than ISO/IEC, IEC, ISO and ITU documents, as identified
in this clause, are valid within the context of this Technical Report. The reference of such a specification
within this Technical Report does not give it any further status within ISO/IEC. In particular, it does not give
the referenced specification the status of an International Standard.

lowest level of the three-level addressing hierarchy, found in bits 7 through 0 of an address identifier
(see 3.2.1)
NOTE See FC-SW-3.

NL_Port that is observing the rules of private loop behavior
NOTE See FC-AL-2 and FC-DA.
3.2.45
Public NL_Port
NL_Port that attempts a fabric login and may transfer frames through the FL_Port
NOTE A Public NL_Port observes the rules of public loop behavior and/or private loop behavior. See FC-AL-2 and FC-DA.

Directory Service and the Alias Service)
NOTE A Service provides access to one or more Servers, see FC-GS-4.
3.2.50

WKA
address identifier defined to access a Service
NOTE See FC-FS-2.

3.3 Editorial conventions
In FC-MI-2, a number of conditions, mechanisms, sequences, parameters, events, states, or similar terms
are printed with the first letter of each word in uppercase and the rest lowercase (e.g., Exchange, Class).
Any lowercase uses of these words have the normal technical English meanings.

Lists sequenced by letters (e.g., a-red, b-blue, c-green) show no ordering relationship between the listed
items. Numbered lists (e.g., 1-red, 2-blue, 3-green) show a ordering between the listed items.
The ISO/IEC convention of numbering is used (i.e., the thousands and higher multiples are separated by a
space and a comma is used as the decimal point.)  A comparison of the American and ISO conventions
are shown in table 1.
Table 1 – ISO/IEC and American Conventions
ISO/IEC American
0,6 0.6
1 000 1,000
1 323 462,9 1,323,462.9
In case of any conflict between figure, table, and text, the text, then tables, and finally figures take prece-
dence. Exceptions to this convention are indicated in the appropriate clauses.
In all of the figures, tables, and text of this document, the most significant bit of a binary quantity is shown
on the left side. Exceptions to this convention are indicated in the appropriate clauses.
When the value of the bit or field is not relevant, x or xx appears in place of a specific value.
Numbers that are not immediately followed by lower-case b or h are decimal values.
Numbers immediately followed by lower-case b (xxb) are binary values.
Numbers or upper case letters immediately followed by lower-case h (xxh) are hexadecimal values.
