RFC 4935 Fabric Configuration Server MIB August 2007

1. Introduction

This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for information related
to a Fibre Channel network's Fabric Configuration Server function,
which provides a means by which a management application can discover
Fibre Channel fabric topology and attributes. Discovered topology
includes Interconnect Elements (i.e., switches, hubs, bridges, etc.)
and their ports, as well as "platforms" that consist of one or more
Fibre Channel nodes.

This memo was previously approved by INternational Committee for
Information Technology Standards (INCITS) Task Group T11.5
(http://www.t11.org); this document is a product of the IETF's IMSS
working group.

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 BCP 14, RFC 2119
[RFC2119].

2. 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].

3. Short Overview of Fibre Channel

The Fibre Channel (FC) is logically a bidirectional point-to-point
serial data channel, structured for high performance. Fibre Channel
provides a general transport vehicle for higher-level protocols such
as Small Computer System Interface (SCSI) command sets, the High-
Performance Parallel Interface (HIPPI) data framing, IP (Internet
Protocol), IEEE 802.2, and others.

Physically, Fibre Channel is an interconnection of multiple
communication points, called N_Ports, interconnected either by a

DeSanti, et al. Standards Track [Page 3]

RFC 4935 Fabric Configuration Server MIB August 2007

switching network, called a Fabric, or by a point-to-point link. A
Fibre Channel "node" consists of one or more N_Ports. A Fabric may
consist of multiple Interconnect Elements, some of which are
switches. An N_Port connects to the Fabric via a port on a switch
called an F_Port. When multiple FC nodes are connected to a single
port on a switch via an "Arbitrated Loop" topology, the switch port
is called an FL_Port, and the nodes' ports are called NL_Ports. The
term Nx_Port is used to refer to either an N_Port or an NL_Port. The
term Fx_Port is used to refer to either an F_Port or an FL_Port. A
switch port, which is interconnected to another switch port via an
Inter-Switch Link (ISL), is called an E_Port. A B_Port connects a
bridge device with an E_Port on a switch; a B_Port provides a subset
of E_Port functionality.

Many Fibre Channel components, including the Fabric, each node, and
most ports, have globally unique names. These globally unique names
are typically formatted as World Wide Names (WWNs). More information
on WWNs can be found in [FC-FS]. WWNs are expected to be persistent
across agent and unit resets.

Fibre Channel frames contain 24-bit address identifiers that identify
the frame's source and destination ports. Each FC port has both an
address identifier and a WWN. When a Fabric is in use, the FC
address identifiers are dynamic and are assigned by a switch. Each
octet of a 24-bit address represents a level in an address hierarchy,
with a Domain_ID being the highest level of the hierarchy.

The Fibre Channel Fabric Configuration Server provides a way for a
management application to discover Fibre Channel fabric topology and
attributes. The Fabric Configuration Server is designed so that it
can be distributed among switches and accessed from any Nx_Port.
However, the Fabric Configuration Server is not restricted or
required to be part of/within a Fabric.

The information registered with and available from each Fabric
Configuration Server is modeled as a Fabric consisting of one or more
Interconnect Elements that each have some number of physical Ports,
and one or more Fibre Channel nodes grouped together into Platforms
to facilitate discovery and management. The Ports are connected
either to other Ports on other Interconnect Elements, or to Nx_Ports.
Each Interconnect Element may have attributes including its name,
type, Domain Identifier, Management Identifier, Logical Name,
Management Address(es), Information List, Zoning Enforcement Status,
etc. Each Port may have attributes including its name, type, TX
type, Module type, physical port number, attached port name(s), port
state, speed, etc. Each platform may have attributes including its
name, type, description, label, location, management address, etc.

DeSanti, et al. Standards Track [Page 4]

RFC 4935 Fabric Configuration Server MIB August 2007

The Fibre Channel Fabric Configuration Server is defined in the FC-GS
specification. The Fabric Configuration Server is one of a set of
functions that are collectively known as the Management Service. The
latest version of the specification is [FC-GS-5].

The latest standard for an interconnecting Fabric containing multiple
Fabric Switch elements is [FC-SW-4]. [FC-SW-4] carries forward the
earlier specification for the operation of a single Fabric in a
physical infrastructure, and augments it with the definition of
Virtual Fabrics and with the specification of how multiple Virtual
Fabrics can operate within one (or more) physical infrastructures.
The use of Virtual Fabrics provides for each frame to be tagged in
its header to indicate which one of several Virtual Fabrics that
frame is being transmitted on. All frames entering a particular
"Core Switch" [FC-SW-4] (i.e., a physical switch) on the same Virtual
Fabric are processed by the same "Virtual Switch" within that Core
Switch.

4. Relationship to Other MIBs

The first standardized MIB for Fibre Channel [RFC2837] was focused on
Fibre Channel switches. It has been replaced by the more generic
Fibre Channel Management MIB [RFC4044], which defines basic
information for Fibre Channel hosts and switches, including
extensions to the standard IF-MIB for Fibre Channel interfaces.

This MIB extends beyond [RFC4044] to cover the functionality, in
Fibre Channel switches, of providing Fibre Channel's Fabric
Configuration Server function.

This MIB imports some common Textual Conventions from T11-TC-MIB
[RFC4439] and from T11-FC-NAME-SERVER-MIB [RFC4438]. It also imports
URLString from NETWORK-SERVICES-MIB [RFC2788].

5. MIB Overview

This MIB module provides the means for monitoring the operation of,
and configuring some parameters of, one or more Fabric Configuration
Servers (FCS) in a Fibre Channel (FC) network. The capabilities
provided include triggering a discovery of the configuration of one
or more Fabrics, retrieving the results of such a discovery, as well
as controlling and monitoring the operation of an FCS. The
discovered configuration contains information about:

- Interconnect Elements (IEs), i.e., switches, hubs, bridges, etc.,
- Ports on IEs, and
- Platforms that consist of one or more FC nodes.

DeSanti, et al. Standards Track [Page 5]

RFC 4935 Fabric Configuration Server MIB August 2007

5.1. Fibre Channel Management Instance

A Fibre Channel management instance is defined in [RFC4044] as a
separable managed instance of Fibre Channel functionality. Fibre
Channel functionality may be grouped into Fibre Channel management
instances in whatever way is most convenient for the
implementation(s). For example, one such grouping accommodates a
single SNMP agent having multiple AgentX [RFC2741] sub-agents, with
each sub-agent implementing a different Fibre Channel management
instance.

The object, fcmInstanceIndex, is IMPORTed from the FC-MGMT-MIB
[RFC4044] as the index value to uniquely identify each Fibre Channel
management instance, for example, within the same SNMP context
([RFC3411], section 3.3.1).

5.2. Switch Index

The FC-MGMT-MIB [RFC4044] defines the fcmSwitchTable as a table of
information about Fibre Channel switches that are managed by Fibre
Channel management instances. Each Fibre Channel management instance
can manage one or more Fibre Channel switches. The Switch Index,
fcmSwitchIndex, is IMPORTed from the FC-MGMT-MIB as the index value
to uniquely identify a Fibre Channel switch amongst those (one or
more) managed by the same Fibre Channel management instance.

5.3. Fabric Index

With multiple Fabrics, each Fabric has its own instances of the
Fabric-related management instrumentation. Thus, this MIB defines
all Fabric-related information in tables that are INDEXed by an
arbitrary integer, named a "Fabric Index". The syntax of a Fabric
Index is T11FabricIndex, imported from T11-TC-MIB [RFC4439]. When a
device is connected to a single physical Fabric, without use of any
virtual Fabrics, the value of this Fabric Index will always be 1. In
an environment of multiple virtual and/or physical Fabrics, this
index provides a means to distinguish one Fabric from another.

It is quite possible, and may even be likely, that a Fibre Channel
switch will have ports connected to multiple virtual and/or physical
Fabrics. Thus, in order to simplify a management protocol query
concerning all the Fabrics to which a single switch is connected,
fcmSwitchIndex will be listed before t11FcsFabricIndex when they both
appear in the same INDEX clause.

DeSanti, et al. Standards Track [Page 6]

RFC 4935 Fabric Configuration Server MIB August 2007

5.4. The MIB Groups

This section describes the six MIB groups contained in the MIB
module.

5.4.1. The t11FcsDiscoveredConfigGroup Group

This group contains the Fabric configuration information discovered
by Fabric Configuration Servers.

5.4.2. The t11FcsDiscoveryStatusGroup Group

This group contains objects by which to monitor the status of
discovery of Fabric configurations by Fabric Configuration Servers.

5.4.3. The t11FcsDiscoveryControlGroup Group

This group contains objects for requesting a Fabric Configuration
Server to discover the configuration of one or more Fabrics.

5.4.4. The t11FcsStatisticsGroup Group

This group contains objects for Fabric Configuration Server
statistics information.

5.4.5. The t11FcsNotificationGroup Group

This group contains three notifications, generated when an FCS:

- rejects a registration, deregistration, or query request;
- completes discovery on a range of Fabrics;
- learns that a management address of an Interconnect Element has
changed.

5.4.5.1. Flow Control for Notifications

When defining SNMP notifications for events that occur in the data-
plane, the maximum frequency of their generation needs to be
considered. Unless there is some limiting factor, such notifications
need to be flow-controlled in some way, e.g., defined such that after
some maximum number within a specified time interval have occurred,
further notifications are suppressed for some subsequent time
interval. However, as and when such a suppression occurs, the
Network Management System (NMS) that didn't receive the notifications
(because they were suppressed) needs to be able to obtain an
indication of how many were suppressed. Therefore, an additional
Counter32 object needs to be defined, and/or a new type of
notification needs to be defined for use at the end of the interval.

DeSanti, et al. Standards Track [Page 7]

RFC 4935 Fabric Configuration Server MIB August 2007

While this is extra complexity, it is necessary for notifications
that need to be flow-controlled.

In contrast, for notifications such as all the ones defined in this
MIB module, which are generated due to control-plane events (and are
not able to start a chain reaction):

- estimating the maximum number that could possibly be generated per
unit time for each type of notification is too simplistic. For
example, it's unreasonable to ask how many of the
t11FcsDiscoveryCompleteNotify notifications can be generated in a
time interval, because it depends on several factors: how big is
the network? how many Virtual Fabrics need to be discovered? how
quickly can the operator ask for another discovery after the last
one completes?

- the extra complexity of flow-controlling these types of
notifications is not warranted.

5.4.6. The t11FcsNotificationInfoGroup Group

This group contains notification control and notification information
objects for monitoring Fabric Configuration Server request rejection
and discovery of topology information.

5.5. OS Logical Unit Number (LUN) Map Entries

A "Platform" is defined in FC-GS-5 to be not only a set of zero or
more FC nodes, but also a set of zero or more "OS LUN Map Entries"
(see Figure 8 in [FC-GS-5]). Information on "OS LUN Map Entries" is
not included in this T11-FC-FABRIC-CONFIG-SERVER-MIB. Instead,
information on LUN Maps can be obtained via the scsiLunMapGroup
object group defined in the SCSI-MIB [RFC4455].

can operate within one (or more) physical infrastructures,
and this index value is used to uniquely identify a
particular (physical or virtual) Fabric within a physical
infrastructure.

In a Fabric conformant to versions earlier than FC-SW-4,
only a single Fabric could operate within a physical
infrastructure, and thus, the value of this Fabric Index
was defined to always be 1."

DESCRIPTION
"The status of the discovery for the particular Fabric.

Initially when the switch comes up, all instances of this
object have the value: 'localOnly', and the database
contains only local information, i.e., no information
discovered via the Fabric Configuration Server protocol
specified in FC-GS-5.

If t11FcsFabricDiscoveryStart is set to 'start' for a
range of Fabrics that includes this Fabric, then the
value of this object transitions to 'inProgress'. When
the discovery completes, this object transitions to
'completed', and the data is cached for the minimum
interval of time specified by
t11FcsFabricDiscoveryTimeOut. After this interval has
been exceeded, the data may be lost, in which case, the
value of this object changes to 'localOnly'.

This object cannot be set via SNMP to any value other
than 'localOnly'. If this object is set (via SNMP) to
'localOnly', the cached data for the Fabric is discarded
immediately, and if a discovery initiated from this
switch was in progress for this Fabric, then that
discovery is aborted."

RFC 4935 Fabric Configuration Server MIB August 2007

7. IANA Considerations

IANA has assigned a MIB OID (162) under the mib-2 subtree.

8. Security Considerations

There are several management objects defined in this MIB module with
a MAX-ACCESS clause of read-write and/or read-create. Such objects
may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations. These objects and their
sensitivity/vulnerability is:

t11FcsFabricDiscoveryRangeLow
t11FcsFabricDiscoveryRangeHigh
t11FcsFabricDiscoveryTimeOut
t11FcsFabricDiscoveryStart -- the ability to specify parameters
for, and trigger the start of,
a topology discovery.
t11FcsDiscoveryStatus -- the ability to abort a discovery, or
invalidate discovered information.
t11FcsReqRejectNotifyEnable
t11FcsDiscoveryCompNotifyEnable
t11FcsMgmtAddrChangeNotifyEnable -- the ability to enable/disable
notifications.

Such objects may be considered sensitive or vulnerable in some
network environments. For example, the ability to invalidate
discovered topology may afford an attacker the ability to hide the
presence of unauthorized equipment on the network. The support for
SET operations in a non-secure environment without proper protection
can have a negative effect on network operations.

Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. These are the tables and objects and their
sensitivity/vulnerability:

t11FcsIeTable
t11FcsMgmtAddrListTable
t11FcsPortTable
t11FcsAttachPortNameListTable
t11FcsPlatformTable

DeSanti, et al. Standards Track [Page 45]

RFC 4935 Fabric Configuration Server MIB August 2007

t11FcsNodeNameListTable -- contains information about the topology
of the Fibre Channel network.

t11FcsStatsTable -- contains statistics information about the
operation of the Fabric Configuration Server.

SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.

It is RECOMMENDED that implementors consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).

Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
