Internet Draft Fibre Channel Management MIB February 2002
1. The SNMP Network Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [RFC2571].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
RFC 1155 [RFC1155], RFC 1212 [RFC1212] and RFC 1215 [RFC1215].
The second version, called SMIv2, is described in RFC 2578
[RFC2578], RFC 2579 [RFC2579] and RFC 2580 [RFC2580].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in RFC 1157 [RFC1157]. A second version of the SNMP
message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC 1901 [RFC1901]
and RFC 1906 [RFC1906]. The third version of the message
protocol is called SNMPv3 and described in RFC 1906 [RFC1906],
RFC 2572 [RFC2572] and RFC 2574 [RFC2574].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in RFC 1157 [RFC1157]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[RFC1905].
o A set of fundamental applications described in RFC 2573
[RFC2573] and the view-based access control mechanism described
in RFC 2575 [RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
Expires August 2002 [Page 3]
Internet Draft Fibre Channel Management MIB February 2002
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
2. Change Log
This section to be deleted before publication as an RFC.
2.1. Initial version: draft-ietf-ips-fcmgmt-mib-00.txt
Initial version derived from draft-ietf-ipfc-fcmgmt-int-mib-07.txt and
RFC 2837, and published on 22 January 2002.
2.2. Changes made in draft-ietf-ips-fcmgmt-mib-01.txt
- support added for Class F traffic.
- the description of Class 1 changed to "not widely-implemented"
(instead of "obsolete"), and a reference to FC-MI added.
- Counter32 objects added in order to support old SNMPv1-only systems
which cannot support standard Counter64 objects.
3. Short Overview of Fibre Channel
The Fibre Channel (FC) is logically a bidirectional point-to-point
serial data channel, structured for high performance capability. The
Fibre Channel provides a general transport vehicle for higher level
protocols such as Intelligent Peripheral Interface (IPI) and 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
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
Expires August 2002 [Page 4]
Internet Draft Fibre Channel Management MIB February 2002
is interconnected to another switch port via an Inter Element Link
(IEL), 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 [WWN1] and [WWN2]. WWNs are expected to be
persistent across agent and unit resets. Fibre Channel frames contain
24-bit addresses identifers which identify the frame's source and
destination ports.
4. MIB Overview
This MIB contains the notion of a Fibre Channel management instance,
which is defined 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.
This MIB contains eleven MIB groups, as follows.
4.1. The fcmInstanceBasicGroup group
This group contains basic information about a Fibre Channel managed
instance, including its name and description, the Fibre Channel
function(s) it performs, and optional pointers to hardware and/or
software components.
4.2. The fcmSwitchBasicGroup group
This group contains basic information about a Fibre Channel switch,
including its domain-id and whether it is the principal switch of its
fabric.
4.3. The fcmPortBasicGroup group
This group contains basic information about a Fibre Channel port,
including its port name (WWN), the name of the node (if any) of which it
is a part, the type of port, the classes of service it supports, its
transmitter and connector types, and the higher level protocols it
supports.
Expires August 2002 [Page 5]
Internet Draft Fibre Channel Management MIB February 2002
Each Fibre Channel port is represented by an entry in the ifTable (see
below). The tables relating to ports in this MIB are indexed by the
port's value of ifIndex.
4.4. The fcmPortStatsGroup group
This group contains traffic statistics, which are not specific to any
particular class of service, for Fibre Channel ports.
4.5. The fcmPortClass23StatsGroup group
This group contains traffic statistics which are specific to Class 2 or
Class 3 traffic on Fibre Channel ports, including class-specific frame
and octet counters and counters of busy and reject frames.
4.6. The fcmPortLcStatsGroup group
Some of the statistics in the fcmPortClass23StatsGroup can increase
rapidly enough to warrant them being defined using the Counter64 syntax.
However, some old SNMP systems do not (yet) support Counter64 objects.
Thus, this group defines low-capacity (Counter32-based) equivalents for
the Counter64-based statistics in the fcmPortClass23StatsGroup group.
4.7. The fcmPortClassFStatsGroup group
This group contains traffic statistics which are specific to Class F
traffic on the E_Ports of a Fibre Channel switch.
4.8. The fcmPortErrorsGroup group
This group contains counters of various error conditions which can occur
on Fibre Channel ports."
4.9. The fcmSwitchPortGroup group
This group contains information about ports on a Fibre Channel switch.
For an Fx_Port, it includes the port's timeout values, its hold-time,
and its capabilities in terms of maximum and minimum buffer-to-buffer
credit allocations, maximum and minimum data field size, and support for
class 2 and class 3 sequenced delivery. For an E_Port, it includes the
buffer-to-buffer credit allocation and data field size.
Expires August 2002 [Page 6]
Internet Draft Fibre Channel Management MIB February 2002
4.10. The fcmSwitchLoginGroup group
This group contains information, known to a Fibre Channel switch, about
its attached/logged-in Nx_Ports and the service parameters which have
been agreed with them.
4.11. The fcmLinkBasicGroup group
This group contains information, known to a local Fibre Channel
management instance, about Fibre Channel links, including links which
terminate locally.
5. Relationship to Other MIBs
This MIB is a replacement for two other MIBs: RFC 2837, and the Fibre
Channel Management Integration MIB which was originally submitted as an
Internet Draft to the IETF's IPFC Working Group as draft-ietf-ipfc-
fcmgmt-int-mib-0n.txt.
5.1. The Interfaces Group MIB
The Interfaces Group MIB [RFC2863] contains generic information about
all lower layer interfaces, i.e., interfaces which are (potentially)
below the internet layer. Thus, each Fibre Channel port should have its
own row in the ifTable, and that row will contain the generic
information about the interface/port. The Interfaces Group MIB
specifies that additional information which is specific to a particular
type of interface media, should be defined in a media-specific MIB.
This MIB is the media-specific MIB for Fibre Channel ports/interfaces.
Section 4 of [RFC2863] requires that a media-specific MIB clarify how
the generic definitions apply for the particular type of media. The
clarifications for Fibre Channel interfaces are as follows.
5.1.1. Layering Model
The Interfaces Group MIB permits multiple ifTable entries to be defined
for interface sub-layers, and for those multiple entries to be arranged
in a stack.
For Fibre Channel interfaces, no sublayers are defined and a Fibre
Channel interface will typically have no other ifTable rows stacked on
top of it, nor underneath it.
Expires August 2002 [Page 7]
Internet Draft Fibre Channel Management MIB February 2002
5.1.2. Virtual Circuits
This Fibre Channel MIB does not deal with virtual circuits.
5.1.3. ifRcvAddressTable
The ifRcvAddressTable does not apply to Fibre Channel interfaces.
5.1.4. ifType
The value of ifType for a Fibre Channel interface is 56.
5.1.5. ifXxxOctets
The definitions of ifInOctets and ifOutOctets (and similarly,
ifHCInOctets and ifHCOutOctets) specify that their values include
framing characters. For Fibre Channel interfaces, they include all the
octets contained in frames between the Start-of-Frame and End-of-Frame
delimiters (excluding the delimiters).
5.1.6. Specific Interface Group MIB Objects
The following table provides specific implementation guidelines for
applying the objects defined in the Interfaces Group MIB to Fibre
Channel interfaces. For those objects not listed here, refer to their
generic definitions in [RFC2863]. (RFC 2863 takes precedence over these
guidelines in the event of any conflict.)
Object Guidelines
ifType 56
ifMtu The MTU as seen by a higher layer
protocol, like IP. That is, when IP is
running over the interface, this object is
the size of the largest IP datagram that
can be sent/received over the interface.
ifSpeed For 1Gbs, this will be 1,000,000,000; for
2Gbs, it will be 2,000,000,000. If auto-
negotiation is implemented and enabled on
an interface, and the interface has not
yet negotiated to an operational speed,
this object SHOULD reflect the maximum
speed supported by the interface.
Expires August 2002 [Page 8]
Internet Draft Fibre Channel Management MIB February 2002
ifPhysAddress The interface's 24-bit Fibre Channel
Address Identifier, or the zero-length
string if no Address Identifier has been
assigned to the interface.
ifAdminStatus Write access is not required, and support
for 'testing' is not required.
ifOperStatus Support for 'testing' is not required.
The value 'dormant' has no meaning for
Fibre Channel interfaces.
ifInOctets The number of octets of information
ifHCInOctets contained in received frames between the
Start-of-Frame and End-of-Frame delimiters
(excluding the delimiters).
ifInUcastPkts The number of unicast frames received,
ifHCInUcastPkts i.e., the number of Start-of-Frame
delimiters received for unicast frames.
ifInErrors The sum for this interface of
fcmPortLossofSynchs
fcmPortLossofSignals
fcmPortPrimSeqProtocolErrors
fcmPortInvalidTxWords
fcmPortInvalidCRCs
fcmPortAddressErrors
fcmPortDelimiterErrors
fcmPortTruncatedFrames
fcmPortEncodingDisparityErrors
plus any errors in fcmPortOtherErrors
which were input errors.
ifOutOctets The number of octets of information
ifHCOutOctets contained in transmitted frames between
the Start-of-Frame and End-of-Frame
delimiters (excluding the delimiters).
ifOutUcastPkts The number of frames transmitted,
ifHCOutUcastPkts i.e., the number of start-of-frame
delimiters transmitted for unicast frames.
Expires August 2002 [Page 9]
Internet Draft Fibre Channel Management MIB February 2002
ifOutErrors This is the number of errors in
fcmPortOtherErrors which were output
errors.
ifInMulticastPkts These counters are not incremented
ifInBroadcastPkts (unless a proprietary mechanism for
ifOutMulticastPkts multicast/broadcast is supported).
ifOutBroadcastPkts
ifHCInMulticastPkts
ifHCInBroadcastPkts
ifHCOutMulticastPkts
ifHCOutBroadcastPkts
ifLinkUpDownTrapEnable Refer to [RFC2863]. Default is 'enabled'
ifHighSpeed The current operational speed of the
interface in millions of bits per second.
For 1Gbs, this will be 1000; for 2Gbs, it
will be 2000. If auto-negotiation is
implemented and enabled on an interface,
and the interface has not yet negotiated
to an operational speed, this object
SHOULD reflect the maximum speed supported
by the interface.
ifPromiscuousMode This will normally be 'false'
ifConnectorPresent This will normally be 'true'.
5.2. Entity MIB
The Entity MIB [RFC2737] contains information about individual physical
components and any hierarchical relationship which may exist between
them. Any Fibre Channel management instance with a relationship to a
physical component (or to a hierarchy of physical components) will have
its value of the fcmInstancePhysicalIndex object contain a pointer to
the relevant row in the Entity MIB. If there is no correspondence to a
physical component (or said component does not have a row in the Entity
MIB), then the value of fcmInstancePhysicalIndex is zero. (Note that an
implementation is not required to support a non-zero value of
fcmInstancePhysicalIndex.)
Expires August 2002 [Page 10]
Internet Draft Fibre Channel Management MIB February 2002
5.3. Host Resources MIB
The Host Resources MIB [RFC2790] includes information about installed
software modules. Any Fibre Channel management instance with a
correspondence to a software module, will have its value of the
fcmInstanceSoftwareIndex object contain a pointer to the relevant row in
the Host Resources MIB. If there is no correspondence to a software
module (or said software module does not has a row in the Host Resources
MIB), then the value of fcmInstanceSoftwareIndex is zero. (Note that an
implementation is not required to support a non-zero value of
fcmInstanceSoftwareIndex.)

10. Security Considerations
There are a number of management objects defined in this MIB that have a
MAX-ACCESS clause of read-write. 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.
There are a number of managed objects in this MIB that contain what
could be considered as sensitive information. In particular, the
objects which provide information on network topology:
fcmLinkEnd1NodeWwn
fcmLinkEnd1PhysPortNumber
fcmLinkEnd1PortWwn
fcmLinkEnd2NodeWwn
fcmLinkEnd2PhysPortNumber
fcmLinkEnd2PortWwn
Expires August 2002 [Page 65]
Internet Draft Fibre Channel Management MIB February 2002
fcmLinkEnd2AgentAddress
fcmLinkEnd2PortType
fcmLinkEnd2UnitType
fcmLinkEnd2FcAddressId
Therefore, it may be important in some environments to control read
access to these objects and possibly to even encrypt their values when
sending them over the network via SNMP. Not all versions of SNMP
provide features for such a secure environment.
SNMPv1 by itself is not a secure environment. 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.
It is recommended that the implementors consider the security features
as provided by the SNMPv3 framework. Specifically, the use of the User-
based Security Model RFC 2574 [RFC2574] and the View-based Access
Control Model RFC 2575 [RFC2575] is recommended.
It is then a customer/user responsibility to ensure that the SNMP entity
giving access to an instance of this MIB, 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.

11. Comparison to draft-ietf-ipfc-fcmgmt-int-mib-07.txt
The decision on whether this section is permanent will be made prior to
publication of this document as an RFC.
11.1. Problems with draft-ietf-ipfc-fcmgmt-int-mib-07.txt
The Fibre Channel Management Integration MIB had the following major
problems:
- It wasn't formatted using SMIv2, which is mandatory.
- The MIB seemed to have been defined with the notion that it would
be the only MIB that a Fibre Channel product will require. The
notion of an agent implementing just a single MIB was abandoned by
the IETF in 1992 as being non-scaleable. Rather, a Fibre Channel
MIB needed to be another MIB in the continuing series of MIBs
defined by the IETF, and thus, it needed to be consistent with its
predecessors. In other words, there are existing MIBs which all
SNMP agents must support, even if the support of Fibre Channel
interfaces is the only functionality that they have. Thus, it was
essential that the Fibre Channel Integration MIB contained only
objects for information which is specific to Fibre Channel. All
objects relevant to non-Fibre Channel environments needed to be
removed. This issue applied to a large fraction of the objects
defined in the MIB.
- The MIB had some but not complete overlap in functionality with RFC
2837.
- Every SNMP agent must implement the ifTable. The ifTable counters
are the MIB objects most well-used by administrators in SNMP
management. SNMP agents need to implement a row in the ifTable for
each of their network interfaces, including their Fibre Channel
interfaces. The IF-MIB requires a media-specific MIB to specify
how that type of interface uses the ifTable (see section 4 in RFC
2863). RFC 2837 doesn't do that, and nor did the Fibre Channel
Integration MIB.
- It incorrectly used the OCTET STRING syntax (instead of Counter32
or Counter64) for counters.

11.2. Detailed Changes
11.2.1. Removal of Sensor-related objects
Information about sensors is not specific to Fibre Channel, and
therefore should not be in this MIB. (At the time of writing, the the
IETF's ENTITY MIB Working Group has produced a first draft of a Sensor
MIB, see [SENSOR].) This removed the need for:
connUnitSensorTable (and all its contents)
connUnitNumSensors
connUnitSensorStatusChange
11.2.2. Removal of Trap-registration objects
Information about registering "traps" is not specific to Fibre Channel,
and therefore should not be in this MIB. (For similar functionality,
see SNMP-NOTIFICATION-MIB and SNMP-TARGET-MIB in RFC 2573). This
removed the need for:
trapMaxClients
trapClientCount
trapRegTable (and all its contents)
11.2.3. Removal of Event-related objects
Information about generic events is not specific to Fibre Channel, and
therefore should not be in this MIB. (For similar functionality, see
the Event group in RFC 2819 and the Notification Log MIB in RFC 3014;
the SNMP-NOTIFICATION-MIB provides for the filtering of notifications.)
This removed the need for:
connUnitEventTable (and all its contents)
connUnitEventFilter
connUnitNumEvents
connUnitMaxEvents
connUnitEventCurrID
connUnitEventTrap
Expires August 2002 [Page 68]
Internet Draft Fibre Channel Management MIB February 2002
11.2.4. Removal of inventory-related information
Aspects of hardware (physical) components are represented in the Entity
MIB (RFC 2737); aspects of software modules are represented in the Host
Resources MIB (RFC 2790). Two new objects provide indexing from this
MIB into those MIBs: one having the value of PhysicalIndex (or zero) and
the other having the value of hrSWInstalledIndex (or zero). These
replaced the need for:
connUnitNumports
connUnitRevsTable (and all its contents)
connUnitNumRevs
connUnitPortRevision
connUnitPortVendor
connUnitProduct
connUnitInfo
connUnitSn
connUnitModuleId
connUnitVendorId
connUnitDeletedTrap
11.2.5. Removal of revision numbers
The forward/backward compatibility rules of how to evolve MIBs are
designed such that MIBs do not have revision numbers. This removed the
need for:
revisionNumber
11.2.6. Removal of other not FC-specific information
Other information was removed because it was not specific to Fibre
Channel:
systemURL
statusChangeTime
configurationChangeTime
connUnitUrl
connUnitUpTime
connUnitState
connUnitContact
connUnitLocation
connUnitProxyMaster
connUnitControl
connUnitStatus
Expires August 2002 [Page 69]
Internet Draft Fibre Channel Management MIB February 2002
connUnitStatusChange
11.2.7. Clean-up of ambiguous/obsolete definitions
Some information in the FC Management integration was obsolete or
ambiguous:
statusChangeTime (obsolete)
configurationChangeTime (obsolete)
connUnitTableChangeTime (obsolete)
connUnitStatusChangeTime (obsolete)
connUnitConfigurationChangeTime (obsolete)
connUnitNumZones (obsolete)
connUnitZoneTable (referenced but not defined)
connUnitLinkCurrIndex (badly defined)
11.2.8. Use of an ifTable entry
The following objects were removed because they duplicated existing IF-
MIB objects:
redundant object existing object(s)

connUnitPortStatCountError ifInErrors & ifOutErrors
connUnitPortStatCountTxObjects ifOutUcastPkts &

connUnitPortName ifAlias
connUnitPortStatObject ifSpecific
connUnitNumports ifNumber
connUnitPortStatusChange linkUp/linkDown
11.2.9. Removed because of AgentX difficulty
An Agentx environment [RFC2741] consists of a master agent and several
sub-agents. It is not difficult to implement the same MIB in several
such sub-agents if all of the MIB's tables have a common index variable
as the first auxiliary object in their INDEX clauses. However, any
scalars which the MIB contains pose a problem for the AgentX
environment. All the (remaining) scalars were therefore removed:
revisionNumber
uNumber
systemURL
11.2.10. FC Management Instance
The term "connectivity unit" was changed to "FC management instance".
The term "connectivity unit" was not properly defined in draft-ietf-
ipfc-fcmgmt-int-mib-07.txt, and its usage provided a confused mixture of
indications to the implementor:
- the definition of FcUnitType suggested it was functional;
- the definition of uNumber suggested it was physical;
- the definition of connUnitProduct suggested it was a vendor's product;
- etc.
The common implementation strategy for "connectivity unit" was whatever
grouping was easiest in providing access to the management
functionality. (One such grouping accommodates a single SNMP agent
having multiple AgentX [RFC2741] sub-agents, each supporting a separate
implementation of the MIB.)
In fact, this scenario is not new; in practice, a "connectivity unit"
will have the same semantics as a management "instance" in other MIBs,
e.g., the IPS WG's own iSCSI MIB. For this MIB, its meaning is: "a
separable managed instance of Fibre Channel functionality". Given this
Expires August 2002 [Page 71]
Internet Draft Fibre Channel Management MIB February 2002
definition, then "FC management instance" is a better name because it is
more accurate and more representative of the definition, than is
"connectivity unit".
11.2.11. Counter Syntax
All packet and octet counters have been changed to be Counter64's (but
Counter32 versions of them are also included for use by old agents).
The error counters have been changed to Counter32's. (In the probably
impossible, and at most improbable, circumstances that the rate of
occurence of errors, even on a 10Gbs Fibre Channel interface, might wrap
faster than a hour, the fact that errors are occurring will almost
certainly be apparent from other MIB objects.)
11.2.12. Obsolete/Little-Used Fibre Channel features
Information relating to Fibre Channel features which are obsolete or not
widely-implemented has been deleted. (For more information, see section
6.2.1 and section 6.2.2 of [FC-MI].)
- Class 1 service,
- Intermix Mode,
- Stacked Conn Mode.
- PH version numbers
Note that with support for Class 1 service being deleted, only class 2
now needs F_BSY, F_RJT, P_BSY and P_RJT counters, and thus they no
longer need to be counted for all classes as well as for class 2, and
therefore these objects:
connUnitPortStatCountFBSYFrames
connUnitPortStatCountPBSYFrames
connUnitPortStatCountFRJTFrames
connUnitPortStatCountPRJTFrames
have been deleted.
11.3. Name Server objects
A table of Name Server information was present in draft-ietf-ipfc-
fcmgmt-int-mib-07.txt. That information is not currently represented in
this MIB, because this MIB is already quite large, and a set of Name
Server objects are expected to be defined in a separate (new) MIB.

fcFxPortCapStackedConnMode and fcFxPortCapIntermix are obsolete,
- fcFxPortBbCredit and fcFxPortRxBufSize are per attached Nx_Port,
