Internet Draft Fibre-Channel Name Server MIB December 2005
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 the Fibre Channel network's Name Server function, which provides a
means for Fibre Channel ports to register and discover Fibre Channel
attributes. Such attributes include names, addresses, types,
features, etc. at various protocol layers.
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. 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
Expires June 2006 [Page 3]
Internet Draft Fibre-Channel Name Server MIB December 2005
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 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.
The Fibre Channel Name Server provides a way for N_Ports and NL_Ports
to register and discover Fibre Channel attributes. Such attributes
include names, addresses, types, features, etc. at various protocol
layers, including upper layer protocols specific to Fibre Channel
(which are sometimes called "FC-4s"). Communication with the Name
Server is via Fibre Channel's CT (Common Transport for Generic
Services) using "Information Units" (called CT_IU's) as either
requests, responses or unsolicited.
Registrations may be performed by a third party. However, the Name
Server may refuse such third party registration for unspecified
reasons. Once registered, the attributes are made available to
requestors.
Requestors could learn about new registrations via periodic polling
of the Name Server, but such polling would generate a considerable
overhead. To avoid this overhead, the Registered State Change
Notification (RSCN) mechanism defined in FC-FS [FC-FS] allows an
Nx_Port to register to receive a RSCN whenever an event occurs that
may affect the state of other Nx_Port(s), including changes in the
information registered with the Name Server.
The Fibre Channel Name Server is defined in the FC-GS specification,
The latest specification is [FC-GS-4]; the previous version was [FC-
GS-3].

Internet Draft Fibre-Channel Name Server MIB December 2005
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 [IF-MIB] for Fibre Channel
interfaces.
This MIB extends beyond [FC-MGMT] to cover the functionality, in
Fibre Channel switches, of providing Fibre Channel's Name Server
function.
This MIB also imports some common Textual Conventions from T11-TC-
MIB, defined in [FC-FAM-MIB].
5. MIB Overview
This MIB module provides the means for monitoring the operation of,
and configuring some parameters of, one or more instances of Fibre
Channel Name Server functionality. (Note that there are no
definitions in this MIB module of "managed actions" which can be
invoked via SNMP.)
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 having 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 to uniquely identify each Fibre Channel
management instance within the same SNMP context ([RFC3411] section
3.3.1).
5.2. Name Server Information Subset
In addition to allowing for multiple Fibre Channel management
instances, this MIB is based on the notion that the information
Expires June 2006 [Page 5]
Internet Draft Fibre-Channel Name Server MIB December 2005
registered with the Name Server is available as one or more subsets.
The MIB allows the different subsets to be accessed either:
- via different SNMP agents/contexts,
- via different Fibre Channel management instances within the
same SNMP agent/context, and/or
- via the same Fibre Channel management instance within the
same SNMP agent/context.
The union of these subsets (across all agents/contexts in the
network) represents the total set of information registered with the
Name Server. Note that the intersection of the subsets is often non-
empty, and the use of the term "subset" does not preclude any subset
from containing the complete set of Name Server information. Each of
these subsets is identified using an index value called a Name Server
Information Subset Index.
Thus, all objects in this MIB are in tables which are INDEX-ed by at
least fcmInstanceIndex and t11NsInfoSubsetIndex, where the latter
contains a Name Server Information Subset Index value.
5.3. Fabric Index
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 one (or more) physical infrastructures. 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 Index". In a
Fabric which is conformant to [FC-SW-3], the value of this Fabric
Index will always be 1.
5.4. The MIB Groups
This section describes the six MIB groups contained in the MIB.
5.4.1. The t11NsDBGroup group
This group contains information about the operation of the Name
Server function acting upon a Name Server Information Subset,
including an indication of whether such operation is performed local
to a particular Fibre Channel switch, or independently of a Fibre
Expires June 2006 [Page 6]
Internet Draft Fibre-Channel Name Server MIB December 2005
Channel switch. It also contains the information currently
registered in a particular Name Server Information Subset.
5.4.2. Three Statistics groups
There are three groups of Name Server statistics objects:
t11NsRequestStatsGroup -- stats about requests,
t11NsRscnStatsGroup -- stats about (Name Server) RSCNs,
t11NsRejectStatsGroup -- stats about rejects,
Each of these groups is conditionally mandatory; specifically, each
group contains objects for particular statistics such that
implementation of the group is mandatory only for an implementation
which counts/captures the group's particular statistics.
The intent here is not to force implementations to capture these
statistics, but rather to have all implementations which do capture
them, provide access to them via the same MIB objects.
5.4.3. The t11NsNotifyGroup group
This group contains a set of notifications which provide for
monitoring the rejections of Name Server registration requests.
5.4.4. The t11NsNotifyControlGroup group
This group contains objects for controlling the generation of, and
for information to be included in, the notifications defined in the
t11NsNotifyGroup group.
5.5. The Actual Values of Objects
The objects defined in the t11NsRegTable represent the values
registered with the Name Server. The SNMP agent MUST report the
actual values, even if they are incorrectly formatted. This is the
reason why, for example, the two objects which represent IP-
addresses, t11NsNodeIpAddress and t11NsPortIpAddress, have the SYNTAX
of OCTET STRING, so that they are able to represent invalid values
(which could not be represented using InetAddressType and
InetAddress).
Similarly, each set of (t11NsRejectReasonCode, t11NsRejReasonCodeExp,
t11NsRejReasonVendorCode) objects must hold the values of the actual
reject, explanation and vendor-specific codes which were present in
Expires June 2006 [Page 7]
Internet Draft Fibre-Channel Name Server MIB December 2005
the generated Reject message (the "Reject CT_IU"), irrespective of
whether such code values were appropriate or not.

10. IANA Considerations
IANA is requested to make a MIB OID assignment to the T11-FC-NAME-
SERVER-MIB module under the appropriate subtree.
11. Security Considerations
There is one management object 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. This
object and its sensitivity/vulnerability is:
t11NsInfoSubsetRejReqNotfyEnable -- the ability to enable/disable
notifications.
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. These are the tables and objects and their
sensitivity/vulnerability:
t11NsRegTable -- contains information about registered Nx_Ports.
t11NsStatsTable -- contains statistics and state information about
the Name Server.
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.
