   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

3.  Short Overview of Fibre Channel

3.1.  Introduction

   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
   is called an FL_Port, and the nodes' ports are called NL_Ports.  The
   term Nx_Port is used to refer to either an N_Port or an NL_Port.  The
   term Fx_Port is used to refer to either an F_Port or an FL_Port.  A
   switch port, which is interconnected to another switch port via an
   Inter-Switch Link (ISL), is called an E_Port.  A B_Port connects a
   bridge device with an E_Port on a switch; a B_Port provides a subset
   of E_Port functionality.

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

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

RFC 4626                 Fibre Channel FSPF MIB           September 2006


   The routing of frames within the Fabric is normally based on a
   routing protocol called Fabric Shortest Path First (FSPF).  FSPF is a
   link state path selection protocol, which is defined in Section 8 of
   [FC-SW-4].  FSPF keeps track of the state of the links on all
   switches in the Fabric and associates a cost with each link.  The
   protocol computes paths from a switch to all the other switches in
   the Fabric by adding the cost of all the links traversed by the path,
   and choosing the path that minimizes the cost.  The collection of
   link states (including cost) of all the switches in a Fabric
   constitutes the topology database (or link-state database).

3.2.  FSPF Protocol

   FSPF has four major components:

   a) A Hello protocol, used to establish connectivity with a neighbor
      switch, to establish the identity of the neighbor switch, and to
      exchange FSPF parameters and capabilities;

   b) A replicated topology database, with protocols and mechanisms to
      keep the databases synchronized across the Fabric;

   c) A path computation algorithm (e.g., Dijkstra's algorithm);

   d) A routing table update.

   The topology database synchronization in turn consists of two major
   components: an initial database synchronization and an update
   mechanism.  The initial database synchronization is used when a
   switch is initialized, or when an Inter-Switch Link (ISL) comes up.
   The update mechanism is used in two circumstances:

   a) When there is a link state change; for example, an ISL going down
      or coming up;

   b) On a periodic basis, to prevent switches from deleting topology
      information from the database.

   Also note that all connections between Fibre Channel switches are
   point-to-point.

3.3.  Virtual Fabrics

   The latest standard for an interconnecting Fabric containing multiple
   Fabric Switch elements is [FC-SW-4].  [FC-SW-4] carries forward the
   previous version's 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



DeSanti, et al.             Standards Track                     [Page 4]

RFC 4626                 Fibre Channel FSPF MIB           September 2006


   Fabrics can operate within one (or more) physical infrastructures.
   The use of Virtual Fabrics provides for each frame to be tagged in
   its header to indicate which one of several Virtual Fabrics that
   frame is being transmitted on.  All frames entering a particular
   "Core Switch" [FC-SW-4] (i.e., a physical switch) on the same Virtual
   Fabric are processed by the same "Virtual Switch" within that Core
   switch.

4.  Relationship to Other MIBs

   The first standardized MIB module for Fibre Channel [RFC4044] 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.

   This MIB module extends beyond [FC-MGMT] to cover the operation of
   the FSPF routing protocol in Fibre Channel switches.

   This MIB module only contains information specific to FSPF.
   Information that would still be applicable if any other routing
   protocol were used is specified in a separate MIB module.

   This MIB module imports some common Textual Conventions from T11-TC-
   MIB, defined in [RFC4439].

5.  MIB Overview

   This MIB module provides the means for monitoring the operation of,
   and configuring some parameters of, one or more instances of the FSPF
   protocol.

5.1.  Fibre Channel Management Instance

   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, with
   each sub-agent implementing a different Fibre Channel management
   instance.

RFC 4626                 Fibre Channel FSPF MIB           September 2006


   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).

5.2.  Switch Index

   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.

5.3.  Fabric Index

   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 module 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.

   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 t11FspfFabricIndex when they
   both appear in the same INDEX clause.

5.4.  The MIB Groups

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

5.4.1.  The t11FspfGeneralGroup Group

   This group provides for per-Fabric monitoring of the FSPF state and
   per-Fabric monitoring/configuration of FSPF parameters.

RFC 4626                 Fibre Channel FSPF MIB           September 2006


5.4.2.  The t11FspfIfGroup Group

   This group provides for per-interface monitoring of FSPF
   state/statistics and per-interface monitoring/configuration of FSPF
   parameters.

5.4.3.  The t11FspfDatabaseGroup Group

   This group permits the monitoring of the information present in the
   FSPF topology database.

5.4.4.  The t11FspfNotificationGroup Group

   This group contains the notifications that are generated on
   asynchronous events related to the operation of FSPF.

           "This table allows the users to configure and monitor
           the FSPF parameters that are per-interface (identified
           by a t11FspfIfIndex value), per-Fabric (identified by a
           t11FspfFabricIndex value), and per-switch (identified by
           values of fcmInstanceIndex and fcmSwitchIndex).

           Creating a row in this table via t11FspfIfRowStatus
           provides the means to specify non-default parameter value(s)
           for an interface at a time when the relevant row in this
           table would not otherwise exist because the interface is
           either down or it is not an E_Port, but the corresponding
           row in the t11FspfTable must already exist.

           After the non-default values have been specified for a
           port's parameters, they need to be retained in this table,
           even when the port becomes 'isolated'.  However, having
           unnecessary rows in this table clutters it up and makes
           those rows that are useful harder for an NMS to find.
           Therefore, when an E_Port becomes isolated, its row gets
           deleted if and only if all of its parameter values are the
           default values; also, when an E_Port becomes non-isolated

           of a row are:
           a) if the corresponding interface is no longer an E_Port
              (e.g., a G_Port which is dynamically determined to be an
              F_Port), and all configurable parameters have default
              values; or
           b) if the interface identified by t11FspfIfIndex no longer
              exists (e.g., because a line-card is physically removed);
              or
           c) if the corresponding row in the t11FspfTable is deleted.

8.  IANA Considerations

   The IANA assigned a MIB OID for the T11-FC-FSPF-MIB module under the
   appropriate subtree.

9.  Security Considerations

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

        t11FspfMinLsArrival, t11FspfMinLsInterval,
        t11FspfIfHelloInterval, t11FspfIfDeadInterval &
        t11FspfIfRetransmitInterval
           -- alter the responsiveness of the FSPF protocol

        t11FspfAdminStatus & t11FspfIfAdminStatus
           -- enable/disable dynamic routing via FSPF

        t11FspfSetToDefault & t11FspfIfSetToDefault
           -- nullify valid configuration changes

        t11FspfIfLinkCostFactor
           -- alter the choice of links

        t11FspfNbrStateChangNotifyEnable
           -- enable/disable notifications.

   The support for SET operations in a non-secure environment without
   proper protection can have a negative effect on network operations.

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

      t11FspfTable -- contains per-Fabric parameters and statistics

      t11FspfIfTable -- contains per-interface parameters and statistics

      t11FspfLsrTable & t11FspfLinkTable -- database of LSR information,

   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.
