Internet Draft Fibre-Channel Domain Management MIB March 2004
1. Introduction
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 a Fibre Channel network's Domain Management.
1.1. Change Log
(This section to be deleted before final publication.)
1.1.1. draft-desanti-fc-domain-manager-00.txt (January 2004)
First version.
1.1.2. draft-desanti-fc-domain-manager-01.txt (March 2004)
The following changes were made for this version:
- The concept of multiple Fabrics operating within a single physical
infrastructure was clarified as a provision to allow for future
standards; an environment conformant to SW-3 operates with exactly
one Fabric. If and when multiple Fabrics are in use, a "Fabric
Indentifier" is used to identify each Fabric; for SW-3, the Fabric
Identifier of the single Fabric always has the value 1.
- t11DmEnable and t11DmFabricName were deleted.
- the DESCRIPTIONs of t11DmGrantedFcIds and t11DmAssignedAreaIdList
were clarified.
- the 'disabled' state was removed from T11DmState.
- t11DmReservedFcIds was deleted and replaced by t11DmAvailableFcIds.
- the t11DmRestart object was moved to an optional object group.
- the t11DmCacheGroup group was changed to be conditional mandatory,
required only for switches which implement the 'sticky' function.
- added t11DmSticky object.
- added more REFERENCE clauses.

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
The Fibre Channel (FC) is logically a bidirectional point-to-point
serial data channel, structured for high performance capability. The
Fibre Channel provides a general transport vehicle for higher level
protocols such as Intelligent Peripheral Interface (IPI) and 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 Element Link (IEL), 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
Expires September 2004 [Page 4]
Internet Draft Fibre-Channel Domain Management MIB March 2004
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 which
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, with a Domain_ID being the highest level of the hierarchy.
Each Switch in a Fabric is assigned one (or more) unique Domain_IDs
using a two-step process. First, one switch, called Principal
Switch, is selected from the switches of a Fabric. Then, the
Principal Switch assigns Domain_IDs to the other switches of the
Fabric. Address assignment within a Domain is performed by the
switch to which that Domain_ID is granted.
4. Relationship to Other MIBs
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 for Fibre Channel interfaces.
This MIB extends beyond [FC-MGMT] to cover the functionality, in
Fibre Channel switches, which is used to manage fabric configuration,
domains, and addresses within a domain.
This document also contains a MIB module, T11-TC-MIB, to define
Textual Conventions useful for multiple MIBs defined by T11, which
could be moved to its own document if appropriate.

5. MIB Overview
This section explains the use of a Fabric Identifier, and describes
the six MIB groups contained in the MIB.
5.1. Fabric Identifier
The current standard for an interconnecting Fabric consisting of
multiple Fabric Switch elements is [FC-SW-3], which describes the
operation of a single Fabric in a physical infrastructure. It is
possible that future standards will define how multiple Fabrics could
operate within a single physical infrastructure. In such a scenario,
each Fabric would, of course, have its own management
instrumentation. Therefore, to *allow* for this future possibility,
this MIB defines all Fabric-related information in tables which are
INDEX-ed by an arbitrary integer, named a "Fabric Identifier". In a
Fabric which is conformant to [FC-SW-3], the value of this Fabric
Identifier will always be 1.
5.2. The t11DmGroup group
This group contains basic information about the Domain management
functionality within a switch.
5.3. The t11DmDatabaseGroup group
This group contains information about which switches are assigned to
which domains.
5.4. The t11DmAreaGroup group
This group contains information about which port-ids have been
assigned within the areas of the local domain.
5.5. The t11DmCacheGroup group
This conditional mandatory group contains information about all the
FC address identifier assignments which have been recently released.
This cache is kept to provide the so-called "sticky" functionality of
a best effort attempt for (short-term) re-assignment of the same FC
address identifiers.
Expires September 2004 [Page 6]
Internet Draft Fibre-Channel Domain Management MIB March 2004
5.6. The t11DmCommandGroup group
This optional group contains objects used for initiating an operation
on a Fabric.
5.7. The t11DmNotificationGroup group
This group contains notifications of significant events concerning
the domain management functionality within a switch.

DESCRIPTION
"The configured Domain_ID of the local switch on this

The meaning of this object depends on
t11DmConfigDomainIdType object.
If t11DmConfigDomainIdType is 'preferred', then domain ID
configured is called 'preferred Domain_ID'. The valid
values are between 0 and 239. In a situation where
this domain could not be assigned, any other domain ID
would be acceptable. The value '0' means any domain ID.
If t11DmConfigDomainIdType is 'static', then domain ID is

called 'static Domain_ID' and valid values are between
1 and 239. In a situation where this domain was
non-zero but could not be assigned, no other domain ID
would be acceptable.
If the Domain Manager is enabled on the Fabric, then an
RDI (Request Domain_ID) will be sent requesting this
Domain_ID. If a Domain_ID is not able to be granted
in the case of 'preferred', or if a 'static' Domain_ID is
configured but not able to be granted, then it is an error
condition. When this error occurs, the E_Ports on that
Fabric will be isolated and the administrator will be
informed via a 't11DmDomainIdNotAssigned' notification.
If the domain manager is not enabled, then the static
Domain_ID is assumed to be granted, if it has been
configured (to a valid number).
If either of the domain IDs are not configured with a
non-zero value on this Fabric and if the domain manager
is not enabled, then
- switch will isolate all its E_Ports on the Fabric.
- the administrator will be informed via a notification
't11DmDomainIdNotAssigned'."

is deleted.
Creating entries in this table via t11DmIfRowStatus
provides the means to specify non-default parameter values
for an interface at a time when that interface is either
down or is a non-E_Port.
So an entry in this table exists when one or both of
these conditions holds:
- one or more configuration parameters have non-default
values for an interface which is either down or a
non-E_Port and corresponding Fabric has an entry in
the t11DmTable, and/or
- the interface is an E_Port and it is up.
This has a number of consequences:
- an entry exists for a non-E_Port or an E_Port which is
Expires September 2004 [Page 19]
Internet Draft Fibre-Channel Domain Management MIB March 2004
down whenever that interface has non-default parameters and
the corresponding Fabric has an entry in the t11DmTable;
- an entry is not able to be created (via t11DmIfRowStatus)
for an interface with default parameters; instead, the
agent creates/deletes an entry for an interface with
default parameters according to whether the E_Port is
up or down.
- an entry is not able to be created via t11DmIfRowStatus
unless non-default parameter values are (simultaneously)
configured for an interface which is a non-E_Port or a
down interface, and the correspoding Fabric has
an entry in the t11DmTable.
- deleting an entry via RowStatus when either the
interface is down and configured with non-default
values or the interface is up, is equivalent to
resetting its parameters to their default values.
If the interface is down and was configured with
default values, then the entry would be deleted."

11. Security Considerations
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write:
- to be supplied
Such objects may be considered sensitive or vulnerable in some
network environments. For example, the ability to change network
topology or network speed may afford an attacker the ability to
obtain better performance at the expense of other network users. 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. In particular, these objects provide
information on ...
Expires September 2004 [Page 33]
Internet Draft Fibre-Channel Domain Management MIB March 2004
- to be supplied
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.
