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 Fabric Shortest Path First (FSPF) routing protocol, which is specified in [FC-SW-4]. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].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 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.
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
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.
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.
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.6. The T11-FC-FSPF-MIB Module

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
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,
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.10.
