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].

DeSanti, et al. Standards Track [Page 2] RFC 4626 Fibre Channel FSPF MIB September 2006

 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.

DeSanti, et al. Standards Track [Page 3] 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.

DeSanti, et al. Standards Track [Page 5] 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.

DeSanti, et al. Standards Track [Page 6] 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.

  STATUS       current
  DESCRIPTION
         "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

DeSanti, et al. Standards Track [Page 15] RFC 4626 Fibre Channel FSPF MIB September 2006

         in a particular Fabric, a row in this table needs to exist
         and is automatically created, if necessary.
         The specific conditions for an automated/implicit deletion
         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,

DeSanti, et al. Standards Track [Page 32] RFC 4626 Fibre Channel FSPF MIB September 2006

 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.
