RFC 4939 iSNS MIB July 2007 1. 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]. 2. Introduction The iSNS protocol, as described in RFC 4171 [RFC4171], can be used by IP-based storage devices for dynamic registration and discovery of other storage devices in the network. It has the capability to group devices into storage Discovery Domains, and Discovery Domains into Discovery Domain Sets. The iSNS MIB is designed to allow Simple Network Management Protocol (SNMP) to be used to monitor iSNS servers supporting iSCSI [RFC3720] and iFCP [RFC4172]. 2.1. Requirement Levels 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 [RFC2119]. Gibbons, et al. Standards Track [Page 3]
RFC 4939 iSNS MIB July 2007 3. Technical Description 3.1. iSNS Registered Objects The following entity relationship figure indicates the objects that can be registered in the iSNS, and their relationship to each other. +--------------+ +-----------+ | NETWORK |1 *| | | ENTITY |----| PORTAL | | | | | +--------------+ +-----------+ |1 |1 |* | | | | |* | | +----------+ | | | PORTAL | | | | GROUP | | | +----------+ | | |* | | | | |* |1 |* +----------+ +-------------+ +----------+ +-----------+ | FC |1 *| STORAGE |* *| DISCOVERY|* *| DISCOVERY | | DEVICE |----| NODE |----| DOMAIN |----| DOMAIN | | | | | | | | SET | +----------+ +-------------+ +----------+ +-----------+ * represents 0 to many possible relationships Gibbons, et al. Standards Track [Page 4]
RFC 4939 iSNS MIB July 2007 3.2. iSNS MIB Structure The MIB is divided into sections for iSNS server information, iSNS server registered objects information, and iSNS notifications. +--------------+ +--------------+ | MANAGED iSNS |1 *| CONTROL NODE | | SERVER |----| INFO | | INFO | +--------------+ +--------------+ |1 |1 | | +--------------+ | | *| DDS AND DD | | +------| INFO | | | | | +--------------+ | | +-------------+ | *| REGISTERED | +------------| ENTITIES | | INFO | +-------------+ +-----------------+ | iSNS | | NOTIFICATION | | INFO | +-----------------+ The sections that are required to implement are for iSNS Server management and notification. 3.3. iSNS Server Info The isnsServerInfo section provides the ability to monitor multiple iSNS Server instances. The isnsServerTable table provides information on each server instance. This table is indexed by the variable isnsServerIndex. The table indicates current settings for each iSNS server being managed. The network address, TCP and UDP ports being used by a server for iSNSP registrations and queries can be determined from this table. The count of objects registered in each iSNS server instance is shown in the table isnsNumObjectsTable. The provides a summary of the number Discovery Domain Sets, Discovery Domains, Entities, Portals, Portal Groups, iSCSI Nodes, and iFCP FC Nodes and Ports. Gibbons, et al. Standards Track [Page 5]
RFC 4939 iSNS MIB July 2007 3.3.1. Control Node Information As defined in the iSNS specification, Control Nodes are objects that have been registered with the server and are allowed to manage the iSNS server. These Control Nodes are identified by their iSCSI Node Name or iFCP FC Port Name. The isnsControlNodeInfo section of the MIB provides the ability to view the currently registered set of iSCSI and iFCP control nodes. 3.3.2. Discovery Domain Set (DDS) The isnsDdsInfo section provides information on each registered DDS, the Discovery Domain members of each DDS, for each iSNS Server instance being managed. DDSs provide a method to group multiple Discovery Domains for easier control. As described in the iSNS Specification [RFC4171], a DDS can be enabled or disabled, which in turn enables or disables the member Discovery Domains. Discovery Domains that are contained in an enabled DDS are then enforced by an iSNS Server. 3.3.3. Discovery Domain (DD) The isnsDdInfo section provides information on each registered DD, and the DD members, for each iSNS Server instance being managed. DDs are collections of storage nodes and portals that are allowed to discover one another. DD members can be iSCSI nodes, Entity Portals, or iFCP nodes. 3.3.4. Registered Storage Objects The isnsReg section provides information on the registered storage objects for a specific iSNS Server instance. This section is divided into subsections for Entities, Portals, and iSCSI Nodes, as well as iFCP Port and Node information. 3.3.4.1. Registered Entities The isnsRegEntityInfo section provides information on the registered entities. Entities are collections of storage nodes and portals. 3.3.4.2. Registered Portals The isnsRegPortalInfo section provides information on the registered portals for a specific iSNS Server instance. Portals are logical IP-Address, TCP/UDP Port pairs that provide access to storage nodes contained in the associated Entity. Gibbons, et al. Standards Track [Page 6]
RFC 4939 iSNS MIB July 2007 3.3.4.3. Registered Portal Groups The isnsRegPortalGroupInfo section provides information on the registered portal groups for a specific iSNS Server instance. As described in iSCSI [RFC3720], Portal Groups provide a mapping between Portals and iSCSI Storage Nodes contained in an Entity. 3.3.4.4. Registered iSCSI Nodes The isnsRegIscsiNodeInfo section provides information on the registered iSCSI Nodes for a specific iSNS Server instance. The iSCSI nodes are individual storage targets or initiators. 3.3.4.5. Registered FC Ports The isnsRegFcPortInfo section provides information on the registered FC Ports for a specific iSNS Server instance. The FC Ports are ports associated with an iFCP gateway. 3.3.4.6. Registered FC Nodes The isnsRegFcNodeInfo section provides information on the registered FC Nodes for a specific iSNS Server instance. The FC nodes are individual storage devices associated with an iFCP gateway. 3.4. Multiple Server Instances The management of multiple instances of iSNS servers by the agent is supported. As described in Section 3.3, each managed iSNS server instance has an entry in the table isnsServerTable. 3.5. iSNS Notifications The isnsNotification section provides SNMP notifications for iSNS Server state changes. 4. MIB References The following MIB module has IMPORTS from [RFC2578], [RFC2579], [RFC2580], [RFC3411], [RFC4001], [RFC4044], and [RFC4133]. In REFERENCE clauses, it also refers to [RFC3720], [RFC4171], and [RFC4172]. Gibbons, et al. Standards Track [Page 7]

IANA Considerations The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER values recorded in the SMI Numbers registry: Descriptor OBJECT IDENTIFIER value ---------- ----------------------- isnsMIB { mib-2 163 } This RFC utilizes the IANA registry of iSNS parameters. This registry was created for the iSNS Specification [RFC4171], and is located at http://www.iana.org/assignments/isns-parameters. Specifically, the isnsRegEntityProtocol values used in the MIB module are the values for the Block Storage Protocols that IANA assigns and documents in http://www.iana.org/assignments/isns-parameters. Gibbons, et al. Standards Track [Page 75]
RFC 4939 iSNS MIB July 2007 7. Security Considerations There are no management objects defined in this MIB module that have a MAX-ACCESS clause of read-write and/or read-create. So, if this MIB module is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB module via direct SNMP SET 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: The isnsDdsMemberTable contains information about which Discovery Domains may be enabled at the same time. The isnsDdTable contains information about Discovery Domains, containing storage nodes with an ability to communicate and exchange storage data. The isnsDdIscsiMemberTable indicates which iSCSI nodes are contained in which Discovery Domains. The isnsDdPortalMemberTable indicates which iSCSI portals are contained in which Discovery Domains. The isnsDdFcPortMemberTable indicates which iFCP FC N_Ports are contained in which Discovery Domains. The isnsControlNodeIscsiTable indicates which iSCSI nodes have the ability to possibly control an iSNS server. The isnsControlNodeFcPortTable indicates which iFCP FC N_Ports have the ability to possibly control an iSNS server. The above object tables provide information about storage objects sessions, and can indicate to a user who is communicating and exchanging storage data. 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. Gibbons, et al. Standards Track [Page 76]
RFC 4939 iSNS MIB July 2007 It is RECOMMENDED that implementers 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. 8.
