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.

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

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.
