RFC 4936 FC Zone Server MIB August 2007 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 Zone Server. 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]. 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. Overview of Fibre Channel 3.1. General Overview 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 DeSanti, et al. Standards Track [Page 3]
RFC 4936 FC Zone Server MIB August 2007 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. For an Nx_Port, its WWN is called a N_Port_Name and its address identifier is called an N_Port_ID. 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. 3.2. Zoning Zones within a Fabric provide a mechanism to control frame delivery between Nx_Ports ("Hard Zoning") or to expose selected views of Name Server information ("Soft Zoning"). Communication is only possible when the communicating endpoints are members of a common zone. This technique is similar to virtual private networks in that the Fabric has the ability to group devices into Zones. Hard zoning and soft zoning are two different means of realizing this. Hard zoning is enforced in the Fabric (i.e., switches) whereas soft zoning is enforced at the endpoints (e.g., host bus adapters (HBAs)) by relying on the endpoints to not send traffic to an N_Port_ID not obtained from the Name Server with a few exceptions for well-known N_Port_IDs used to bootstrap the Fabric (e.g., talk to the Name Server). Administrators create Zones to increase network security and to prevent data loss or corruption by controlling access between devices or user groups. Zones may be specifically used to create: DeSanti, et al. Standards Track [Page 4]
RFC 4936 FC Zone Server MIB August 2007 a) Barriers between devices that use different operating systems. It is often critical to separate servers and storage devices with different operating systems because accidental transfer of information from one to another may delete or corrupt data; b) Logical subsets of closed user groups. Administrators may authorize access rights to specific Zones for specific user groups, thereby protecting confidential data from unauthorized access; c) Groups of devices that are separate from devices in the rest of a Fabric. Zones allow certain processes to be performed on devices in a group without interrupting devices in other groups; or d) Temporary access between devices for specific purposes. Administrators may remove Zone restrictions temporarily, then restore Zone restrictions to perform normal processes. 3.3. Zoning Configuration and Management Zones are configured via a Fabric Zone Server, using requests defined in [FC-GS-5]), or via the T11-FC-ZONE-SERVER-MIB module defined in this memo, or via some other mechanism. An Nx_Port may be a member of one or more Zones. Zone membership may be specified by: a) The N_Port_Name of the Nx_Port connected to the switch; b) The N_Port_ID assigned during Fabric Login; c) The Node_Name associated with the Nx_Port; note that the Node_Name may include more than one Nx_Port; d) The F_Port_Name of the Fx_Port to which the Nx_Port is connected; or e) The domain identifier (Domain_ID) and physical port number of the Switch Port to which the Nx_Port is attached. A Fabric's Zone Server may be used to create a Zone by specifying the Zone Members. One or more Zones may be collected into a Zone Set, and a Zone may be a member of more than one Zone Set. A Zone Set creates a collection of Zones that may be activated or deactivated as a single entity across all Switches in a Fabric (e.g., having two Zone Sets, one for normal operation, and a second for backup during off-hours). Only one Zone Set may be activated at one time. Other terminology defined in [FC-GS-5] is: an Active Zone Set is the Zone Set currently enforced by a Fabric; a Zone Set Database is a database of the Zone Sets available to be activated within a Fabric; DeSanti, et al. Standards Track [Page 5]
RFC 4936 FC Zone Server MIB August 2007 and a Zoning Database is a generic term used to indicate a combination of an Active Zone Set and a Zone Set Database. Two distinct sets of management requests, Enhanced and Basic, are defined in [FC-GS-5] to interact with a Fabric Zone Server. Basic Zoning provides compatibility with [FC-GS-4] and earlier versions of Fibre Channel's Generic Services specification. If all the Switches in a Fabric support the Enhanced request set, then it may be used to manage zoning; otherwise, only the Basic request set may be used, in order to support backward compatibility. In the context of Enhanced Zoning Management, a management action (i.e., write access to the Zoning Database) to the Zone Server can only occur inside a server session. A server session is set up using the FC-GS-5's Common Transport (CT) protocol defined in [FC-GS-5]. A server session is delimited by CT protocol requests, Server Session Begin (SSB) and Server Session End (SSE), which are directed to the Management Service and which have the GS_Subtype specifying the Zone Server. Query requests that result in read access to the Zoning Database are not required to be issued inside a server session, although the information returned is not guaranteed to be consistent when supplied outside of a server session. When setting up a server session for Enhanced Zoning, the Zone Server is required to lock the Fabric. This ensures serialized management access to the Zoning Database and guarantees a deterministic behavior. The switch that receives the SSB request is called the 'managing' switch, and it tries to lock the Fabric using the Fabric Management Session Protocol (see section 10.6 of [FC-SW-4]) by sending an Acquire Change Authorization (ACA) request to all other switches in the Fabric. If any switch(es) respond with an SW_RJT indicating failure, then the attempt to lock the Fabric fails and the SSB request is rejected. If all the other switches respond with an SW_ACC indicating success, then the Fabric is locked and the server session can be established. The subsequent SSE request causes a Release Change Authorization (RCA) request to all other switches, and thus, the Fabric to be unlocked. For at least one application other than Zoning, the managing switch uses a different type of request to lock the Fabric, i.e., it sends an Enhanced Acquire Change Authorization (EACA) request to all other switches in the Fabric. An EACA reserves local resources associated with a designated application to ensure the consistency of that application's data. The application is identified in the EACA using an Application_ID (see Table 116 in [FC-SW-4]). A lock that was established via an EACA is released using an Enhanced Release Change Authorization (ERCA) request. DeSanti, et al. Standards Track [Page 6]
RFC 4936 FC Zone Server MIB August 2007 Changes requested in a Zoning Database by Enhanced Zoning commands persist after the end of the Zoning (server) session only if the commands are followed, within the same server session, by a Commit Zone Changes (CMIT) request. On receipt of a CMIT request, the Zone Server checks that the Zoning Database as modified by the outstanding changes will pass the applicable consistency checks, and then distributes it to all other switches in the Fabric using a Stage Fabric Configuration Update (SFC) request. If all other switches accept the SFC request, then the "managing" switch sends an Update Fabric Configuration (UFC) Request to each other switch, and the staged Zoning Database thereby becomes the Fabric's (active) Zoning Database. 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. 4. Relationship to Other MIBs The Fibre Channel Management MIB [RFC4044] defines basic information for Fibre Channel hosts and switches, including extensions to the standard IF-MIB [RFC2863] for Fibre Channel interfaces. This MIB extends beyond [RFC4044] to cover the management of Fibre Channel Zoning Servers, both for Basic Zoning Management and for Enhanced Zoning Management, as defined in the FC-GS-5 specification. This MIB imports some common Textual Conventions from T11-TC-MIB, defined in [RFC4439]. It also imports a TC from T11-FC-NAME-SERVER- MIB, defined in [RFC4438], plus InetAddressType and InetAddress from INET-ADDRESS-MIB [RFC4001]. It also includes a reference to snmpCommunitySecurityName defined in [RFC3584]. DeSanti, et al. Standards Track [Page 7]
RFC 4936 FC Zone Server MIB August 2007 5. MIB Overview This document defines two MIB modules: T11-FC-FABRIC-LOCK-MIB and T11-FC-ZONE-SERVER-MIB. T11-FC-FABRIC-LOCK-MIB supports FC-GS-5's generic capability of locking the Fabric for a particular "application" such as (the management of) Enhanced Zoning. The MIB contains one table in which each entry represents a particular switch being the 'managing' switch of a particular application's Fabric lock. T11-FC-ZONE-SERVER-MIB is specific to the operation of Zone Servers, which can operate in Basic mode or in Enhanced mode. This MIB module imports the T11NsGs4RejectReasonCode textual convention defined in T11-FC-NAME-SERVER-MIB [RFC4438]. 5.1. 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). 5.2. 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. 5.3. Fabric Index Whether operating on a physical Fabric (i.e., without Virtual Fabrics) or within a Virtual Fabric, the operation of a Zone Server within a Fabric is identical. Therefore, this MIB defines all Fabric-related information in tables that are INDEXed by an arbitrary DeSanti, et al. Standards Track [Page 8]
RFC 4936 FC Zone Server MIB August 2007 integer, named a "Fabric Index", having the syntax, T11FabricIndex, which is IMPORTed from the 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 an object with FabricIndex as its syntax when both appear in the same INDEX clause. 5.4. Locking the Fabric The T11-FC-FABRIC-LOCK-MIB module provides for the management of locks on a Fibre Channel Fabric. A Fibre Channel Fabric lock is used to ensure serialized access to some types of management data related to a Fabric, e.g., the Fabric's Zoning Database. Some (managing) applications obtain a lock by initiating server sessions and the Fabric is locked so as to reserve local resources in each Switch. For this usage, the managing switch sends an Acquire Change Authorization (ACA) request to other switches in order to lock the Fabric. For some other applications, a managing switch locks the Fabric using an Enhanced Acquire Change Authorization (EACA) request, which identifies the application on whose behalf the Fabric is being locked with an Application_ID. In this case, only local resources associated with the designated application are reserved. Locks established via ACAs and via EACAs are both represented in the t11FLockTable in the T11-FC-FABRIC-LOCK-MIB. The Application_ID provided by the EACA serves to distinguish between multiple concurrent locks established by EACAs. In order to use this same mechanism to distinguish a lock established via an ACA from each of those established via EACAs, an additional (special) value of Application_ID has been assigned [APPL-ID] for use by this MIB module. Specifically, this newly assigned value will never be used to indicate an Application locked by an EACA, and therefore this MIB module uses it to uniquely distinguish a lock established via an ACA. In other words, with this additional assignment, an Application_ID value can be used to uniquely identify any active lock amongst all those established (on the same Fabric) either by an EACA or an ACA. DeSanti, et al. Standards Track [Page 9]
RFC 4936 FC Zone Server MIB August 2007 5.5. Basic and Enhanced Modes The t11ZsServerOperationMode object indicates whether a Fabric's Zone Server is operating in Basic mode or Enhanced mode. These two modes have a sufficient amount of commonality to make it worthwhile to have one set of MIB objects that are used for the subset of functionality that is common to both modes. To accommodate the differences, additional MIB objects are defined. For Enhanced mode, the additional objects are defined in a group, t11ZsEnhancedModeGroup, which is only required to be implemented in a Zone Server capable of supporting Enhanced mode. The objects specific to Basic mode are always (even in Enhanced mode) expected to be implemented, but when in Enhanced mode, their values are either restricted or do not affect current operations, e.g., - an example of "restricted" is: the distribution of updates to the Zone Server database throughout the Fabric has to be requested explicitly in Basic mode; this functionality is provided in the MIB by the t11ZsServerDistribute object. In contrast, in Enhanced mode, the distribution is an implicit part of the commit function which is initiated using the t11ZsServerCommit object. Thus, when operating in Enhanced mode, t11ZsServerDistribute has a fixed value, and when operating in Basic mode, t11ZsServerCommit has a fixed value. - an example of "do not affect current operations" is: t11ZsServerHardZoning, which specifies whether a switch enforces hard Zoning on a Fabric when in Basic mode. This object is instantiated and could even be modified while in Enhanced mode, but its value only takes effect when in Basic mode. (Note that in Enhanced mode, t11ZsActiveZoneHardZoning specifies whether hard Zoning is enabled on a particular Zone.) 5.6. Persistent Storage A Zone Server Database for a given Fabric consists of the combination of many of the tables defined in this MIB module. In order to ensure that such a Database is consistent, this MIB module defines just one object (t11ZsServerDatabaseStorageType) with a syntax of StorageType, whose value for a given Fabric is defined to be applicable to all of that Fabric's Zone Server Database as defined in all the tables in this MIB module. DeSanti, et al. Standards Track [Page 10]
RFC 4936 FC Zone Server MIB August 2007 5.7. The Active Zone Set and the Zone Set Database As described in FC-GS-5 [FC-GS-5], one of the Zone Sets in the Zone Set Database can be activated to become the Active Zone Set, i.e., the one which is enforced on the Fabric. Get/Add/Remove-type requests are defined in FC-GS-5 to allow access to the Zone Set Database. When the Zone Set Database is modified, such modifications don't affect the Active Zone Set unless and until a subsequent activation. Interaction directly with the Active Zone Set is also possible via the FC-GS-5 requests: 'Activate Direct' and 'Get Active Zone Set'. This is illustrated in the following rendition of Figure 15 of [FC-GS-5]: Zone Set Database +------------------+ | +--------------+ | Get | | Zone Set A | | <=========| |(zones, zone | | | | members,etc.)| | | +--------------+ | Add/ | | Zone Set B | | Activate +------------+ Remove | +------------+ | Zone Set | | =========>| |Zone Set C| |================>| | | +----------+ | | Active | +------------------+ | Zone | | Set | Get Active Zone Set | (enforced) | <==============================================| | | | Activate Direct | | ==============================================>| | | | Deactivate | | ==============================================>| | +------------+ The T11-FC-ZONE-SERVER-MIB module, defined in section 7, models the above structure by having one set of MIB tables for the Zone Set Database and a separate set for the Active Zone Set, specifically: - seven tables for the Zone Set Database: t11ZsSetTable, t11ZsZoneTable, t11ZsSetZoneTable, t11ZsAliasTable, t11ZsZoneMemberTable, t11ZsAttribBlockTable and t11ZsAttribTable. - four tables for the Active Zone Set: t11ZsActiveTable, t11ZsActiveZoneTable, t11ZsActiveZoneMemberTable and t11ZsActiveAttribTable. DeSanti, et al. Standards Track [Page 11]
RFC 4936 FC Zone Server MIB August 2007 5.8. Conformance Groups 5.8.1. The t11ZsBasicGroup This group contains objects to retrieve and to modify the Zoning configuration of a Zone Server capable of operating in Basic mode. 5.8.2. The t11ZsEnhancedModeGroup This group contains objects to retrieve and to modify the Zoning configuration of a Zone Server capable of operating in Enhanced mode. 5.8.3. The t11ZsActivateGroup This group contains objects that allow a Zone Set to be activated via SNMP SetRequests and provide the status and result of such an activation. 5.8.4. The t11ZsStatisticsGroup This group contains objects for collecting Zone Server statistics. 5.8.5. The t11ZsNotificationGroup This group contains notifications for monitoring: Zone merge successes and failures, Zone Server request rejections, changes in the Default Zoning behavior, and the success or failure of an attempt to activate or deactivate a Zone Set. 5.8.5.1. 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 have occurred within a specified time interval, 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 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 those defined in this MIB module, which are generated due to control-plane events (and are not able to start a chain reaction): DeSanti, et al. Standards Track [Page 12]
RFC 4936 FC Zone Server MIB August 2007 - estimating the maximum number that could be generated per unit time for each type of notification is too simplistic. For example, it's unreasonable to ask how many of the t11ZsDefZoneChangeNotify notifications can be generated in a time interval because it depends on several factors: how many operators can be re- configuring the network at the same time? and how frequently can each of them change the Default Zone Setting? - the extra complexity of flow-controlling these types of notifications is not warranted. 5.8.6. The t11ZsNotificationControlGroup This group contains objects that allow each type of notification (in the t11ZsNotificationGroup group) to be independently enabled or disabled. It also contains objects that are used to include useful information in those notifications; these objects are defined as read-only to allow the values contained in the most recent notification to be queried. 6.

RFC 4936 FC Zone Server MIB August 2007 Cisco Systems, Inc. 170 West Tasman Drive San Jose, CA 95134 USA EMail: kzm@cisco.com" DESCRIPTION "The MIB module for the management of locks on a Fibre Channel Fabric. A Fibre Channel Fabric lock is used to ensure serialized access to some types of management data related to a Fabric, e.g., the Fabric's Zoning Database. Some (managing) applications generate Fabric locks by initiating server sessions. Server sessions are defined generically in FC-GS-5 to represent a collection of one or more requests to the session's server, e.g., to the Zone Server. Such a session is started by a Server Session Begin (SSB) request, and terminated by a Server Session End (SSE) request. The switch receiving the SSB is called the 'managing' switch. Some applications require the 'managing' switch to lock the Fabric for the particular application, e.g., for Enhanced Zoning, before it can respond successfully to the SSB. On receipt of the subsequent SSE, the lock is released. For this usage, the managing switch sends an Acquire Change Authorization (ACA) request to other switches to lock the Fabric. For some other applications, a managing switch locks the Fabric using an Enhanced Acquire Change Authorization (EACA) request, which identifies the application on whose behalf the Fabric is being locked with an Application_ID. Fabric locks can also be requested more directly, e.g., through the use of this MIB. In these situations, the term 'managing' switch is used to indicate the switch that receives such a request and executes it by issuing either ACA or EACA requests to other switches in the Fabric. This MIB module defines information about the 'managing' switch for currently-active Fabric locks. Copyright (C) The IETF Trust (2007).

The 'managing switch' is identified by values of fcmInstanceIndex and fcmSwitchIndex. Server sessions for several different types of servers are defined in FC-GS-5. The behavior of a server with DeSanti, et al. Standards Track [Page 15]
RFC 4936 FC Zone Server MIB August 2007 respect to commands received within a server session is specified for each type of server. For some types, parameter changes can only be made within the context of a session, and the setting up of a session requires that the Fabric be locked. A Fabric is locked by one switch, called the 'managing' switch, sending Acquire Change Authorization (ACA) requests to all other switches in the Fabric. For other applications, a Fabric lock is established by the 'managing' switch sending Enhanced Acquire Change Authorization (EACA) requests to other switches in the Fabric. Each EACA request includes an Application_ID value to identify the application requesting the lock. For the benefit of this MIB module, a distinct value of Application_ID has also been assigned/reserved (see ANSI INCITS T11/06-679v0, titled 'FC-SW-5 Letter to T11.5') as a means of distinguishing locks established via Acquire Change Authorization (ACA) requests. This additional assignment allows an Application_ID to be used to uniquely identify any active lock amongst all those established by either an EACA or an ACA. Whenever a Fabric is locked, by the sending of either an ACA or an EACA, a row gets created in the representation of this table for the 'managing' switch. In order to process SNMP SetRequests that make parameter changes for the relevant types of servers (e.g., to the Zoning Database), the SNMP agent must get serialized access to the Fabric (for the relevant type of management data), i.e., the Fabric must be locked by creating an entry in this table via an SNMP SetRequest. Creating an entry in this table via an SNMP SetRequest causes an ACA or an EACA to be sent to all other switches in the Fabric. The value of t11FLockApplicationID for such an entry determines whether an ACA or an EACA is sent. If an entry in this table is created by an SNMP SetRequest, the value of the t11FLockInitiatorType object in that entry will normally be 'snmp'. A row for which the value of t11FLockInitiatorType is not 'snmp' cannot be modified via SNMP. In particular, it cannot be deleted via t11FLockRowStatus.

Standards Track [Page 24]
RFC 4936 FC Zone Server MIB August 2007 Zoning Management, as defined in the FC-GS-5 specification. FC-GS-5 defines (in-band) management operations for manipulating the Zone Set Database, some for use in Basic mode (e.g., 'Add Zone Set (AZS)', etc.), and some for use in Enhanced mode (e.g., Create Zone Set (CZS)', etc.). When Enhanced Zoning Management is in use, FC-GS-5 requires that these in-band management operations be rejected unless they are issued within the context of a GS-5 server session. The use of a server session ensures serialized access to the Zoning Database since the Fabric lock for the Zone Server must be obtained as a part of establishing the server session to the Zone Server. Thus, if and when this MIB is used for Enhanced Zoning Management, SNMP SetRequests that request the modification of zoning definitions must be serialized with respect to the GS-5 requests to modify the Zoning Database. This is achieved by requiring that an SNMP management application must first obtain the Fabric lock for the Zone Server before attempting to modify any zoning definitions. The companion T11-FC-FABRIC-LOCK-MIB module is defined as a means of obtaining the Fabric lock for the Zone Server (or any other server). In Enhanced Zoning Management, a Zone Server keeps track of changes requested in the zoning definitions, but does not update its Zone Set Database unless there is (and until there is) a 'commit' operation. To model this behavior, this MIB module assumes that a Zone Server (in Enhanced mode) takes a snapshot of its Zone Set Database as and when the Fabric lock (for the Zone Server application) is obtained; this snapshot is used to create what is herein called the 'copy' database. It is this 'copy' database that is then updated by SNMP SetRequests (while the Fabric is locked). If and when a 'commit' operation is requested (while the Fabric is still locked), the 'copy' database is then used to overwrite the previously committed contents of the Zone Set Database, and the new Zone Set Database is distributed to all other switches in the Fabric. When the lock is released, any changes made that were not 'committed' are discarded. When this MIB is used for Basic Zoning Management, the same set of MIB objects as used for Enhanced mode are used to make changes to the Database of a Zone Server on a particular switch, but the changes take immediate effect at that switch without an explicit commit. The distribution of DeSanti, et al. Standards Track [Page 25]
RFC 4936 FC Zone Server MIB August 2007 those changes to Zone Servers on other switches in the Fabric is subsequently requested through the use of a separate set of MIB objects. The management information specified in this MIB module includes the Zoning Database for each of one or more Fibre Channel Fabrics. A Zoning Database is a combination of the Fabric's Zone Set Database and its Active Zone Set. The Active Zone Set is the Zone Set currently enforced by the Fabric; a Zone Set Database is a database of the Zone Sets available to be activated within a Fabric. All the MIB objects representing a Zone Set Database are modifiable at any time (irrespective of the value of any RowStatus object), whereas all objects representing the Active Zone Set are always read-only (except to deactivate it and/or activate a different one).

IANA Considerations IANA has assigned two MIB OIDs: one for the T11-FC-FABRIC-LOCK-MIB module (159) and one for the T11-FC-ZONE-SERVER-MIB module (160), under the mib-2 subtree. 9. Security Considerations There are many management objects defined in these MIB modules 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. Specifically, unauthorized write access to *any* of the writable objects in these MIB modules could cause unauthorized manipulation of the Zoning information on a Zone Server, and/or the activation of an unauthorized Active Zone Set in a Fabric. This could result in allowing unauthorized connectivity, and/or denying authorized connectivity, between hosts connected to the Fibre Channel network. It could also cause the suppression of notifications (e.g., of unauthorized operations), or the disruption of network operations due to the generation of unwanted notifications. 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. Unauthorized read access to any of the readable objects in the t11ZsServerTable, t11ZsActiveZoneTable, t11ZsActiveZoneMemberTable, or t11ZsActiveAttribTable tables would reveal information about the DeSanti, et al. Standards Track [Page 79]
RFC 4936 FC Zone Server MIB August 2007 currently authorized connectivity between hosts connected to the Fibre Channel network. Unauthorized read access to any of the readable objects in the t11ZsSetTable, t11ZsZoneTable, t11ZsSetZoneTable, t11ZsAliasTable, t11ZsZoneMemberTable, t11ZsAttribBlockTable, or t11ZsAttribTable tables would reveal information about potential/alternative connectivity that could be authorized between hosts connected to the Fibre Channel network. 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. 10.
