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 network's Routing Table for routing within a Fabric. Managed objects specific to particular routing protocols, such as the Fabric Shortest Path First (FSPF) protocol [FC-SW-4], are not specified in this MIB module.

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].
托管对象通过虚拟信息存储（称为管理信息库或MIB）进行访问。MIB对象通常通过简单网络管理协议（SNMP）进行访问。MIB中的对象是使用管理信息结构（SMI）中定义的机制定义的。本备忘录规定了符合SMIv2的MIB模块，如STD 58、RFC 2578[RFC2578]、STD 58、RFC 2579[RFC2579]和STD 58、RFC 2580[RFC2580]所述。
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 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
从物理上讲，光纤通道是多个通信点（称为N_端口）的互连，这些通信点通过交换网络（称为结构）或点到点链路互连。光纤通道“节点”由一个或多个N_端口组成。一个结构可以由多个互连元件组成，其中一些是交换机。N_端口通过交换机上称为F_端口的端口连接到结构。当多个FC节点通过“仲裁环路”拓扑连接到交换机上的单个端口时，交换机端口
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.
称为FL_端口，节点的端口称为NL_端口。术语Nx_端口用于指N_端口或NL_端口。术语Fx_端口用于指F_端口或FL_端口。通过交换机间链路（ISL）与另一个交换机端口互连的交换机端口称为E_端口。B_端口将桥接设备与交换机上的E_端口连接起来；B_端口提供E_端口功能的子集。
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.
许多光纤通道组件（包括光纤网、每个节点和大多数端口）具有全局唯一的名称。这些全局唯一的名称通常格式化为全球通用名称（WWN）。有关WWN的更多信息，请参见[FC-FS]。WWN预计将在代理和单元重置之间保持不变。
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, a Domain_ID being the highest level of the hierarchy.
光纤通道帧包含24位地址标识符，用于标识帧的源端口和目标端口。每个FC端口都有地址标识符和WWN。在使用结构时，FC地址标识符是动态的，由交换机分配。24位地址的每个八位字节表示地址层次结构中的一个级别，域ID是层次结构的最高级别。
The routing of frames within the Fabric is normally based on the standard routing protocol, called the Fabric Shortest Path First (FSPF) protocol. The operation of FSPF (or of any other routing protocol) allows a switch to generate and maintain its own routing table of how to forward frames it receives; i.e., a table in which to look up the destination address of a received frame in order to determine the best link by which to forward that frame towards its destination.
结构内的帧路由通常基于标准路由协议，称为结构最短路径优先（FSPF）协议。FSPF（或任何其他路由协议）的操作允许交换机生成并维护其自身的路由表，该路由表说明如何转发其接收的帧；i、 例如，一种表，在该表中查找所接收帧的目的地址，以确定向其目的地转发该帧的最佳链路。
The latest standard for an interconnecting Fabric containing multiple Fabric Switch elements is [FC-SW-4] (which replaces the previous revision, [FC-SW-3]). [FC-SW-4] carries forward the existing specification for the operation of a single Fabric in a physical infrastructure, augmenting 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.
包含多个结构交换机元件的互连结构的最新标准为[FC-SW-4]（取代先前版本[FC-SW-3]）。[FC-SW-4]继承了物理基础设施中单个结构操作的现有规范，通过虚拟结构的定义以及多个虚拟结构如何在一个（或多个）物理基础设施中操作的规范对其进行了补充。虚拟结构的使用为每个帧提供了在其标头中标记的功能，以指示该帧在多个虚拟结构中的哪一个上传输。进入同一虚拟结构上特定“核心交换机”[FC-SW-4]（即物理交换机）的所有帧都由该核心交换机内的同一“虚拟交换机”处理。
The first standardized MIB for Fibre Channel [RFC2837] was focussed on Fibre Channel switches. It is being replaced by the more generic Fibre Channel Management MIB [FC-MGMT], which defines basic information for Fibre Channel hosts and switches, including extensions to the standard IF-MIB [RFC2863] for Fibre Channel interfaces.
光纤通道的第一个标准化MIB[RFC2837]集中在光纤通道交换机上。它正被更通用的光纤通道管理MIB[FC-MGMT]所取代，它定义了光纤通道主机和交换机的基本信息，包括光纤通道接口标准IF-MIB[RFC2863]的扩展。
This MIB extends beyond [FC-MGMT] to cover the routing of traffic within a Fabric of a Fibre Channel network. The standard routing protocol for Fibre Channel is FSPF [FC-SW-4]. Another MIB [RFC4626] specifies management information specific to FSPF. This MIB contains routing information that is independent of FSPF (i.e., it would still apply even if a routing protocol other than FSPF were in use in the network).
此MIB扩展到[FC-MGMT]之外，以覆盖光纤通道网络结构内的流量路由。光纤通道的标准路由协议是FSPF[FC-SW-4]。另一个MIB[RFC4626]指定特定于FSPF的管理信息。此MIB包含独立于FSPF的路由信息（即，即使网络中使用了FSPF以外的路由协议，它仍将适用）。
This MIB imports some common Textual Conventions from T11-TC-MIB, defined in [RFC4439].
此MIB从[RFC4439]中定义的T11-TC-MIB中导入一些常见的文本约定。
This MIB module provides the means for monitoring the operation of, and configuring some parameters of, one or more instances of the FSPF protocol. (Note that there are no definitions in this MIB module of "managed actions" that can be invoked via SNMP.)
该MIB模块提供监控FSPF协议一个或多个实例的操作和配置其某些参数的方法。（请注意，此MIB模块中没有可通过SNMP调用的“托管操作”定义。）
A Fibre Channel management instance is defined in [FC-MGMT] 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 with multiple AgentX [RFC2741] sub-agents, each sub-agent implementing a different Fibre Channel management instance.
光纤通道管理实例在[FC-MGMT]中定义为光纤通道功能的可分离托管实例。光纤通道功能可以以对实施最方便的方式分组到光纤通道管理实例中。例如，一个这样的分组容纳一个SNMP代理和多个AgentX[RFC2741]子代理，每个子代理实现不同的光纤通道管理实例。
The object, fcmInstanceIndex, is IMPORTed from the FC-MGMT-MIB [FC-MGMT] as the index value that uniquely identifies each Fibre Channel management instance within the same SNMP context ([RFC3411], Section 3.3.1).
对象fcmInstanceIndex作为索引值从FC-MGMT-MIB[FC-MGMT]导入，该索引值唯一标识同一SNMP上下文中的每个光纤通道管理实例（[RFC3411]，第3.3.1节）。
The FC-MGMT-MIB [FC-MGMT] 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 that uniquely identifies a Fibre Channel switch among those (one or more) managed by the same Fibre Channel management instance.
FC-MGMT-MIB[FC-MGMT]将fcmSwitchTable定义为有关由光纤通道管理实例管理的光纤通道交换机的信息表。每个光纤通道管理实例都可以管理一个或多个光纤通道交换机。交换机索引fcmSwitchIndex作为索引值从FC-MGMT-MIB导入，该索引值唯一标识由同一光纤通道管理实例管理的那些（一个或多个）中的光纤通道交换机。
Whether operating on a physical Fabric (i.e., without Virtual Fabrics) or within a Virtual Fabric, the operation of FSPF within a Fabric is identical. Therefore, this MIB defines all Fabric-related information in tables that are INDEX-ed by an arbitrary integer, named a "Fabric Index", the syntax of which is IMPORTed from the T11-TC-MIB. 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.
无论是在物理结构（即没有虚拟结构）上还是在虚拟结构内操作，结构内FSPF的操作都是相同的。因此，此MIB在表中定义了所有结构相关信息，这些信息由一个名为“结构索引”的任意整数索引，其语法从T11-TC-MIB导入。当设备连接到单个物理结构而不使用任何虚拟结构时，此结构索引的值将始终为1。在包含多个虚拟和/或物理结构的环境中，此索引提供了一种将一个结构与另一个结构区分开来的方法。
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 t11FcRouteFabricIndex when they both appear in the same INDEX clause.
光纤通道交换机很可能（甚至可能）将端口连接到多个虚拟和/或物理结构。因此，为了简化有关单个交换机连接到的所有结构的管理协议查询，当fcmSwitchIndex和T11FCrouteFabriciIndex出现在同一个INDEX子句中时，它们将列在T11FCrouteFabriciIndex之前。
This MIB contains one object group, the t11FcRouteGroup, which contains objects to allow the displaying and the configuring of routes in the Fibre Channel Routing tables for the locally managed switches.
此MIB包含一个对象组t11FcRouteGroup，它包含允许在本地管理交换机的光纤通道路由表中显示和配置路由的对象。
It is normally valuable for a MIB table that contains routes to be ordered such that a management application is able to query the table based on some attribute, without having to read every row in the MIB table. This requires that the rows in the table be ordered according to such attributes, and thus that those attributes be represented by objects included in the table's INDEX clause. Examples of this can be seen in the ipCidrRouteTable [RFC2096] and, more recently, the inetCidrRouteTable in [RFC4292].
对于包含要排序的路由的MIB表来说，它通常很有价值，这样管理应用程序就能够基于某个属性查询该表，而不必读取MIB表中的每一行。这要求表中的行根据这些属性排序，因此这些属性由表的INDEX子句中包含的对象表示。这方面的示例可以在ipCidrRouteTable[RFC2096]中看到，最近，在[RFC4292]中可以看到InetCidErrorOutTable。
While this useful feature results in an unusually large number (ten) of objects in the t11FcRouteTable's INDEX clause, all ten are either integers or strings of 3 (or zero) octet length, so the resulting OIDs are not unusually large. (Specifically, the aggregate number of sub-identifiers to be appended to an OBJECT-TYPE's OID, when naming an instance of an object in the t11FcRouteTable, is at most 22 sub-identifiers; i.e., less than the *minimum* number to be appended for the inetCidrRouteTable table.)
虽然这一有用的特性导致t11FcRouteTable的INDEX子句中的对象数量异常多（十个），但所有十个对象都是整数或长度为3（或零）个八位字节的字符串，因此生成的OID并不异常大。（具体地说，在命名t11FcRouteTable中的对象实例时，要附加到对象类型的OID的子标识符的总数最多为22个子标识符；即，小于inetCidrRouteTable表要附加的*最小*数。）

Such routes are used by a switch to forward frames (of user data) on a Fabric. The conceptual process is based on extracting the Destination Fibre Channel Address Identifier (D_ID) out of a received frame (of user data) and comparing it to each entry of this table that is applicable to the given switch and Fabric. Such comparison consists of first performing a logical-AND of the extracted D_ID with a mask (the value of t11FcRouteDestMask) and second comparing the result of that 'AND' operation to the value of t11FcRouteDestAddrId. A similar comparison is made of the Source Fibre Channel Address Identifier (S_ID) of a frame
