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. 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 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 Expires January 2005 [Page 3] Internet Draft Fibre-Channel Name Server MIB July 2004 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. 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]. 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 Expires January 2005 [Page 4] Internet Draft Fibre-Channel Name Server MIB July 2004 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 Index As well as allowing for multiple Fibre Channel management instances, this MIB also allows for multiple instances of the Name Server functionality within each Fibre Channel management instance. Further, some of the Name Server instances managed by the same Fibre Channel management instance, can operate local to a particular Fibre Channel switch and some can operate independent of any particular switch. Therefore, all objects in this MIB are in tables which are INDEX-ed by at least fcmInstanceIndex and t11NsIndex, where the latter is an index value which uniquely identifies a Name Server instance within a Fibre Channel management instance. Expires January 2005 [Page 5] Internet Draft Fibre-Channel Name Server MIB July 2004 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 four MIB groups contained in the MIB. 5.4.1. The t11NsDBGroup group This group contains information about the operation of the Name Server function, including an indication of whether each Name Server instance operates local to a particular Fibre Channel switch, or independently of any Fibre Channel switch. It also contains the information currently registered with the Name Server. 5.4.2. The t11NsStatsGroup group This group contains Name Server statistics. 5.4.3. The t11NsNotifyControlGroup group This group contains those notification control and notification information objects which are required for monitoring Name Server registrations/de-registrations. 5.4.4. The t11NsNotifyGroup group This group contains notifications which provide for the monitoring of Name Server registrations/de-registrations. 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 Expires January 2005 [Page 6] Internet Draft Fibre-Channel Name Server MIB July 2004 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 pair of t11NsRejectReasonCode and t11NsRejReasonCodeExp objects holds the values of the actual reject code and explanation which was present in the generated Reject message (the "Reject CT_IU"), irrespective of whether such a reject code and explanation were appropriate or not. 6.

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: t11NsRejReqNotifyEnable -- 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 Expires January 2005 [Page 31] Internet Draft Fibre-Channel Name Server MIB July 2004 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.
