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 December 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. 2.3. Changes made in draft-ietf-ips-fcmgmt-mib-02.txt - aligned the meanings of bits of the FcUnitFunctions TC with the latest update to the meanings in the GS-4 specification. - broadened the scope of the fcmEPortTable to apply to any type of port connected to an inter-swithc link, and changed its descriptor to fcmISPortTable. - changed the fcmLinkTable to be optional. - fixed some minor typos 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 Expires December 2002 [Page 4] Internet Draft Fibre Channel Management MIB February 2002 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 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 identifers which 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. 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 Expires December 2002 [Page 5] Internet Draft Fibre Channel Management MIB February 2002 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. 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. Expires December 2002 [Page 6] Internet Draft Fibre Channel Management MIB February 2002 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 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 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. Expires December 2002 [Page 7] Internet Draft Fibre Channel Management MIB February 2002 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. 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). Expires December 2002 [Page 8] Internet Draft Fibre Channel Management MIB February 2002 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. 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 Expires December 2002 [Page 9] Internet Draft Fibre Channel Management MIB February 2002 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. 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 Expires December 2002 [Page 10] Internet Draft Fibre Channel Management MIB February 2002 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.) 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.) Expires December 2002 [Page 11] Internet Draft Fibre Channel Management MIB February 2002 6.

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 December 2002 [Page 66] 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.

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. Expires December 2002 [Page 68] Internet Draft Fibre Channel Management MIB February 2002 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 December 2002 [Page 69] 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 December 2002 [Page 70] 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 & ifHCOutUcastPkts connUnitPortStatCountRxObjects ifInUcastPkts & ifHCInUcastPkts connUnitPortStatCountTxElements ifOutOctets & ifHCOutOctets connUnitPortStatCountRxElements ifInOctets & ifHCInOctets connUnitPortStatCountRxMulticastObjects ifInMulticastPkts & ifHCInMulticastPkts connUnitPortStatCountTxMulticastObjects ifOutMulticastPkts & ifHCOutMulticastPkts connUnitPortStatCountRxBroadcastObjects ifInBroadcastPkts & ifHCInBroadcastPkts connUnitPortStatCountTxBroadcastObjects ifOutBroadcastPkts & ifHCOutBroadcastPkts connUnitPortFCId ifPhysAddress Expires December 2002 [Page 71] Internet Draft Fibre Channel Management MIB February 2002 connUnitPortControl ifAdminStatus connUnitPortState ifAdminStatus connUnitPortHWState ifOperStatus connUnitPortStatus ifOperStatus 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 December 2002 [Page 72] 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. Expires December 2002 [Page 73] Internet Draft Fibre Channel Management MIB February 2002 11.4. Additional objects Support for Class F traffic, including 32-bit octet and frame counters, has been added. Expires December 2002 [Page 74] Internet Draft Fibre Channel Management MIB February 2002 12. 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.
