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 the Fibre Channel.
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 the 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, the Fibre Channel is an interconnection of multiple
communication points, called N_Ports, interconnected either by a
McCloghrie Standards Track [Page 2]
RFC 4044 Fibre Channel Management MIB May 2005
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 refers to either an N_Port or an NL_port. The term
Fx_Port refers to either an F_Port or an FL_port. A switch port,
which 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 address identifiers that identify
the frame's source and destination ports. Each FC port has an
address identifier and a WWN. When a fabric is in use, the FC
address identifiers are dynamic and are assigned by a switch.
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. To represent such multiple Fibre Channel management
instances within the same SNMP context (see section 3.3.1 of
[RFC3411]), all tables in this MIB are INDEX-ed by fcmInstanceIndex,
which is defined as an arbitrary integer to uniquely identify a
particular 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.
McCloghrie Standards Track [Page 3]
RFC 4044 Fibre Channel Management MIB May 2005
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.
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 that 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 that 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 that can
occur on Fibre Channel ports.
McCloghrie Standards Track [Page 4]
RFC 4044 Fibre Channel Management MIB May 2005
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
sizes, and support for class 2 and class 3 sequenced delivery. For
an E_Port or B_Port, it includes the buffer-to-buffer credit
allocation and data field size.
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 that
have been agreed with them.
4.11. The fcmLinkBasicGroup Group
This group contains information known to a local Fibre Channel
management instance, and concerning Fibre Channel links including
those 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, and
is now available as [MIB-FA].
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.
McCloghrie Standards Track [Page 5]
RFC 4044 Fibre Channel Management MIB May 2005
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.
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.
McCloghrie Standards Track [Page 6]
RFC 4044 Fibre Channel Management MIB May 2005
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 an
operational speed, this object SHOULD
reflect the maximum speed supported by
the interface.
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
that were input errors.
McCloghrie Standards Track [Page 7]
RFC 4044 Fibre Channel Management MIB May 2005
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.
ifOutErrors This is the number of errors in
fcmPortOtherErrors that 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
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 that 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
McCloghrie Standards Track [Page 8]
RFC 4044 Fibre Channel Management MIB May 2005
there is no correspondence with 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.)
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 have a row in the
Host Resources MIB), then the value of fcmInstanceSoftwareIndex is
zero. (Note that an agent 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:
fcmInstanceTextName
fcmInstanceDescr
fcmSwitchDomainId
fcmPortAdminType
fcmPortAdminSpeed
fcmISPortClassFCredit
Such objects may be considered sensitive or vulnerable in some
network environments. For example, the ability to change network
topology or network speed may afford an attacker the ability to
obtain better performance at the expense of other network users;
setting fcmSwitchDomainId to an invalid value could lead to denial of
service in some configurations. 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. In particular, these objects provide
information on network topology:
fcmLinkEnd1NodeWwn
fcmLinkEnd1PhysPortNumber
fcmLinkEnd1PortWwn
fcmLinkEnd2NodeWwn
fcmLinkEnd2PhysPortNumber
McCloghrie Standards Track [Page 59]
RFC 4044 Fibre Channel Management MIB May 2005
fcmLinkEnd2PortWwn
fcmLinkEnd2AgentAddress
fcmLinkEnd2PortType
fcmLinkEnd2UnitType
fcmLinkEnd2FcAddressId
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.
11. IANA Considerations
11.1. OID Assignment
IANA has made a MIB OID assignment under the transmission branch.
Specifically, transmission 56 has been assigned as the OID for
fcMgmtMIB. This sub-identifier was requested because this MIB
contains the media-specific definitions that correspond to the ifType
value of fibreChannel(56).
11.2. FC Port Type Registry
IANA has established a registry for Fibre Channel Port Types. The
registry is split into disjointed subset ranges:
1) a 'standard' range for Fibre Channel Port Types that have been
standardized by the InterNational Committee for Information
Technology Standards (INCITS)'s Technical Committee T11. This
range will be subject to the 'Expert Review' and 'Specification
Required' policies described in [RFC2434], with the following
provisions:
- the Expert Reviewer is to be appointed by the IESG.
McCloghrie Standards Track [Page 60]
RFC 4044 Fibre Channel Management MIB May 2005
- the Expert Reviewer shall obtain approval (or rejection) from
INCITS Technical Committee T11 via the chair of that Committee.
Rejected values shall not be added to the registry.
- if the addition is approved, the Expert shall advise IANA of
how to record the reference to the T11 specification document
that describes the newly added port type(s), and that is
considered to be the "other permanent and readily available
reference" required by [RFC2434].
The initial assignments in the 'standard' range will be as follows:
Assigned
Value Type Meaning
-------- ------ -------
1 unknown for use when the type is not known,
or is "unidentified" as specified in
section 5.1.2.10 of [FC-GS-3]
2 other used for types without assigned values
3 -- an obsolete value, not to be re-assigned
4 N_Port see [FC-FS]
5 NL_Port see [FC-FS]
6 F_Port see [FC-FS]
7 FL_Port see [FC-FS]
8 E_Port see [FC-FS]
9 B_Port see [FC-FS]
10 G_Port see [FC-SW-3]
11 GL_Port see [FC-SW-3]
12 F/NL_Port see [FC-AL-2]
The above range extends up to a maximum of 9,999.
2) a range assigned under the "Private Use" policy described in
[RFC2434] for values intended for private use by one party or
among mutually consenting parties.
Values in this range extend from 10,000 to 99,999. IANA will not
make any allocations from this range.
3) values larger than 99,999 are RESERVED.

RFC 4044 Fibre Channel Management MIB May 2005
12. Comparison to the Fibre Channel Management Integration MIB
12.1. Problems with the Fibre Channel Management Integration MIB
The Fibre Channel Management Integration MIB [MIB-FA] 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-scalable. 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 that 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 that 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). [RFC2837] doesn't do that, nor did the Fibre
Channel Integration MIB.
- It incorrectly used the OCTET STRING syntax (instead of Counter32
or Counter64) for counters.
12.2. Detailed Changes
12.2.1. 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
IETF's ENTITY MIB Working Group has produced a first draft of a
Sensor MIB, see [RFC3433].) This removed the need for:
McCloghrie Standards Track [Page 62]
RFC 4044 Fibre Channel Management MIB May 2005
connUnitSensorTable (and all its contents)
connUnitNumSensors
connUnitSensorStatusChange
12.2.2. 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)
12.2.3. 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
12.2.4. 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
McCloghrie Standards Track [Page 63]
RFC 4044 Fibre Channel Management MIB May 2005
connUnitVendorId
connUnitDeletedTrap
12.2.5. 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
12.2.6. 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
connUnitStatusChange
12.2.7. 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)
12.2.8. Use of an ifTable Entry
The following objects were removed because they duplicated existing
IF-MIB objects:

RFC 4044 Fibre Channel Management MIB May 2005
redundant object existing object(s)

connUnitNumports ifNumber
connUnitPortStatusChange linkUp/linkDown
12.2.9. 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 that the MIB contains pose a problem for the
AgentX environment. All the (remaining) scalars were therefore
removed:
revisionNumber
uNumber
systemURL
McCloghrie Standards Track [Page 65]
RFC 4044 Fibre Channel Management MIB May 2005
12.2.10. FC Management Instance
The term "connectivity unit" was changed to "FC management instance".
The term "connectivity unit" was not properly defined in [MIB-FA],
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 the "connectivity unit" was
which ever grouping provided access to the management functionality
the easiest. (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 definition, the "FC management instance" is a better name
because it is more accurate and more representative of the definition
than is "connectivity unit".
12.2.11. 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 occurrence of errors, even on a 10Gbs Fibre Channel
interface, might wrap faster than an hour, the fact that errors are
occurring will almost certainly be apparent from other MIB objects.)
12.2.12. Obsolete/Little-Used Fibre Channel Features
Information relating to Fibre Channel features that 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].)
McCloghrie Standards Track [Page 66]
RFC 4044 Fibre Channel Management MIB May 2005
- 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 the following objects have been deleted:
connUnitPortStatCountFBSYFrames
connUnitPortStatCountPBSYFrames
connUnitPortStatCountFRJTFrames
connUnitPortStatCountPRJTFrames
12.3. Name Server Objects
A table of Name Server information was present in
the Fibre Channel Management Integration MIB [MIB-FA].
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.
12.4. Additional Objects
Support for Class F traffic, including 32-bit octet and frame
counters, has been added.
13. Comparison to RFC 2837
This MIB is a superset of RFC 2837, except for the following:
- the fcFeClass1AccountingGroup group is obsolete,
- fcFxPortConnectedNxPort, fcFxPortFcphVersionHigh,
fcFxPortFcphVersionLow, fcFxPortFcphVersionAgreed,
fcFxPortStackedConnModeAgreed, fcFxPortIntermixSuppAgreed,
fcFxPortCapStackedConnMode, and fcFxPortCapIntermix are obsolete,
- fcFxPortBbCredit and fcFxPortRxBufSize are per attached Nx_Port,
- fcFxPortBbCreditAvailable is ephemeral,
- fcFeModuleTable is mostly contained in the entPhysicalTable,
- fcFxPortPhysAdminStatus, fcFxPortPhysOperStatus, and
fcFxPortPhysLastChange have equivalents in the ifTable.
