Abstract

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 Fabric Configuration Server function of a Fibre Channel network.

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 Fabric Configuration Server function, which provides a means by which a management application can discover Fibre Channel fabric topology and attributes. Discovered topology includes Interconnect Elements (i.e., switches, hubs, bridges, etc.) and their ports, as well as "platforms" that consist of one or more Fibre Channel nodes.

This memo was previously approved by INternational Committee for Information Technology Standards (INCITS) Task Group T11.5 (http://www.t11.org); this document is a product of the IETF's IMSS working group.

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 BCP 14, RFC 2119 RFC2119.

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.

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 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, with a Domain_ID being the highest level of the hierarchy.

The Fibre Channel Fabric Configuration Server provides a way for a management application to discover Fibre Channel fabric topology and attributes. The Fabric Configuration Server is designed so that it can be distributed among switches and accessed from any Nx_Port. However, the Fabric Configuration Server is not restricted or required to be part of/within a Fabric.

The information registered with and available from each Fabric Configuration Server is modeled as a Fabric consisting of one or more Interconnect Elements that each have some number of physical Ports, and one or more Fibre Channel nodes grouped together into Platforms to facilitate discovery and management. The Ports are connected either to other Ports on other Interconnect Elements, or to Nx_Ports. Each Interconnect Element may have attributes including its name, type, Domain Identifier, Management Identifier, Logical Name, Management Address(es), Information List, Zoning Enforcement Status, etc. Each Port may have attributes including its name, type, TX type, Module type, physical port number, attached port name(s), port state, speed, etc. Each platform may have attributes including its name, type, description, label, location, management address, etc.

The Fibre Channel Fabric Configuration Server is defined in the FC-GS specification. The Fabric Configuration Server is one of a set of functions that are collectively known as the Management Service. The latest version of the specification is [FC-GS-5].

The latest standard for an interconnecting Fabric containing multiple Fabric Switch elements is [FC-SW-4]. [FC-SW-4] carries forward the earlier specification for the operation of a single Fabric in a physical infrastructure, and augments 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.

Relationship to Other MIBs

The first standardized MIB for Fibre Channel RFC2837 was focused on Fibre Channel switches. It has been replaced by the more generic Fibre Channel Management MIB RFC4044, 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 RFC4044 to cover the functionality, in Fibre Channel switches, of providing Fibre Channel's Fabric Configuration Server function.

This MIB imports some common Textual Conventions from T11-TC-MIB RFC4439 and from T11-FC-NAME-SERVER-MIB RFC4438. It also imports URLString from NETWORK-SERVICES-MIB RFC2788.

MIB Overview

This MIB module provides the means for monitoring the operation of, and configuring some parameters of, one or more Fabric Configuration Servers (FCS) in a Fibre Channel (FC) network. The capabilities provided include triggering a discovery of the configuration of one or more Fabrics, retrieving the results of such a discovery, as well as controlling and monitoring the operation of an FCS. The discovered configuration contains information about:

- Interconnect Elements (IEs), i.e., switches, hubs, bridges, etc., - Ports on IEs, and - Platforms that consist of one or more FC nodes.

Fibre Channel Management Instance

A Fibre Channel management instance is defined in RFC4044 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 RFC4044 as the index value to uniquely identify each Fibre Channel management instance, for example, within the same SNMP context (RFC3411, section 3.3.1).

Switch Index

The FC-MGMT-MIB RFC4044 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 to uniquely identify a Fibre Channel switch amongst those (one or more) managed by the same Fibre Channel management instance.

Fabric Index

With multiple Fabrics, each Fabric has its own instances of the Fabric-related management instrumentation. Thus, this MIB defines all Fabric-related information in tables that are INDEXed by an arbitrary integer, named a "Fabric Index". The syntax of a Fabric Index is T11FabricIndex, imported from T11-TC-MIB RFC4439. 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 t11FcsFabricIndex when they both appear in the same INDEX clause.

The MIB Groups

This section describes the six MIB groups contained in the MIB module.

The t11FcsDiscoveredConfigGroup Group

This group contains the Fabric configuration information discovered by Fabric Configuration Servers.

The t11FcsDiscoveryStatusGroup Group

This group contains objects by which to monitor the status of discovery of Fabric configurations by Fabric Configuration Servers.

The t11FcsDiscoveryControlGroup Group

This group contains objects for requesting a Fabric Configuration Server to discover the configuration of one or more Fabrics.

The t11FcsStatisticsGroup Group

This group contains objects for Fabric Configuration Server statistics information.

The t11FcsNotificationGroup Group

This group contains three notifications, generated when an FCS:

- rejects a registration, deregistration, or query request; - completes discovery on a range of Fabrics; - learns that a management address of an Interconnect Element has

 changed.
Flow Control for Notifications

When defining SNMP notifications for events that occur in the data- plane, the maximum frequency of their generation needs to be considered. Unless there is some limiting factor, such notifications need to be flow-controlled in some way, e.g., defined such that after some maximum number within a specified time interval have occurred, further notifications are suppressed for some subsequent time interval. However, as and when such a suppression occurs, the Network Management System (NMS) that didn't receive the notifications (because they were suppressed) needs to be able to obtain an indication of how many were suppressed. Therefore, an additional Counter32 object needs to be defined, and/or a new type of notification needs to be defined for use at the end of the interval.

While this is extra complexity, it is necessary for notifications that need to be flow-controlled.

In contrast, for notifications such as all the ones defined in this MIB module, which are generated due to control-plane events (and are not able to start a chain reaction):

- estimating the maximum number that could possibly be generated per

 unit time for each type of notification is too simplistic.  For
 example, it's unreasonable to ask how many of the
 t11FcsDiscoveryCompleteNotify notifications can be generated in a
 time interval, because it depends on several factors: how big is
 the network? how many Virtual Fabrics need to be discovered? how
 quickly can the operator ask for another discovery after the last
 one completes?

- the extra complexity of flow-controlling these types of

 notifications is not warranted.

The t11FcsNotificationInfoGroup Group

This group contains notification control and notification information objects for monitoring Fabric Configuration Server request rejection and discovery of topology information.

OS Logical Unit Number (LUN) Map Entries

A "Platform" is defined in FC-GS-5 to be not only a set of zero or more FC nodes, but also a set of zero or more "OS LUN Map Entries" (see Figure 8 in [FC-GS-5]). Information on "OS LUN Map Entries" is not included in this T11-FC-FABRIC-CONFIG-SERVER-MIB. Instead, information on LUN Maps can be obtained via the scsiLunMapGroup object group defined in the SCSI-MIB RFC4455.

IANA Considerations

IANA has assigned a MIB OID (162) under the mib-2 subtree.

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 is:

  t11FcsFabricDiscoveryRangeLow
  t11FcsFabricDiscoveryRangeHigh
  t11FcsFabricDiscoveryTimeOut
  t11FcsFabricDiscoveryStart -- the ability to specify parameters
                                for, and trigger the start of,
                                a topology discovery.
  t11FcsDiscoveryStatus      -- the ability to abort a discovery, or
                                invalidate discovered information.
  t11FcsReqRejectNotifyEnable
  t11FcsDiscoveryCompNotifyEnable
  t11FcsMgmtAddrChangeNotifyEnable -- the ability to enable/disable
                                      notifications.

Such objects may be considered sensitive or vulnerable in some network environments. For example, the ability to invalidate discovered topology may afford an attacker the ability to hide the presence of unauthorized equipment on the network. 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:

  t11FcsIeTable
  t11FcsMgmtAddrListTable
  t11FcsPortTable
  t11FcsAttachPortNameListTable
  t11FcsPlatformTable
  t11FcsNodeNameListTable -- contains information about the topology
                             of the Fibre Channel network.
  t11FcsStatsTable -- contains statistics information about the
                      operation of the Fabric Configuration 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.
