2.  Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in TCP/IP based internets.

Internet Draft                  iSCSI MIB                   October 2001


   In particular it defines objects for managing a client using the
   iSCSI (SCSI over TCP) protocol.  It is meant to match the latest
   version of iSCSI defined in [ISCSI].

   MIB, and to Keith McCloghrie for serving as advisor to the team.


4.  The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

    o   An overall architecture, described in RFC 2571 [RFC2571].

    o   Mechanisms for describing and naming objects and events for the
        purpose of management.  The first version of this Structure of
        Management Information (SMI) is called SMIv1 and described in
        STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
        1215 [RFC1215].  The second version, called SMIv2, is described
        in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and
        STD 58, RFC 2580 [RFC2580].

    o   Message protocols for transferring management information.  The
        first version of the SNMP message protocol is called SNMPv1 and
        described in STD 15, RFC 1157 [RFC1157].  A second version of
        the SNMP message protocol, which is not an Internet standards
        track protocol, is called SNMPv2c and described in RFC 1901
        [RFC1901] and RFC 1906 [RFC1906].  The third version of the
        message protocol is called SNMPv3 and described in RFC 1906
        [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].

    o   Protocol operations for accessing management information.  The
        first set of protocol operations and associated PDU formats is
        described in STD 15, RFC 1157 [RFC1157].  A second set of

Internet Draft                  iSCSI MIB                   October 2001


        protocol operations and associated PDU formats is described in
        RFC 1905 [RFC1905].

    o   A set of fundamental applications described in RFC 2573
        [RFC2573] and the view-based access control mechanism described
        in RFC 2575 [RFC2575].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [RFC2570].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (use of Counter64).  Some machine readable
   information in SMIv2 will be converted into textual descriptions in
   SMIv1 during the translation process.  However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.

   All the MIB objects defined in this MIB have at most a read-only MAX-
   ACCESS clause, i.e., none are writable.  This is a conscious decision
   by the working group to limit this MIB's scope.  It is possible that
   this restriction could be lifted after implementation experience, by
   means of additional tables (using the AUGMENTS clause) for
   configuration and extended entity information.

   WORK - Update the above to reflect our writable attributes


5.  Relationship to Other MIBs

   The iSCSI MIB is layered between the SCSI MIB [SCSI-MIB] (work in
   progress) and the TCP MIB [RFC2012], and provides attributes that can
   be used to relate its objects to objects in the SCSI and TCP MIBs.
   Each iSCSI initiator and target is related to one SCSI initiator or
   target, and each iSCSI connection is related to one TCP connection.


6.  Discussion

   This MIB structure is intended to satisfy fault, performance, and
   security management for an iSCSI implementation.  It is structured
   around the well-known iSCSI objects, such as targets, initiators,



Bakke, Muchow              Expires April 2002                   [Page 3]


Internet Draft                  iSCSI MIB                   October 2001


   sessions, connections, and the like.

   It is worthwhile to note that this is an iSCSI MIB and as such
   reflects only iSCSI objects (real or virtual). This means that this
   MIB will not directly deal with real SCSI objects or the SCSI
   protocol in general. This are represented within the SCSI MIB (work
   in progress)

   The iSCSI MIB consists of eight "objects", each of which is
   represented by one or more tables.  This section contains a brief
   description of the "object" hierarchy and a description of each
   object, followed by a discussion of the actual SNMP table structure
   within the objects.

6.1.  iSCSI MIB Object Model

   The top-level object in this structure is the iSCSI instance, which
   "contains" all of the other objects.

   iscsiInstance
      -- A distinct iSCSI entity within the managed system.
      -- Most implementations will have just one of these.
      iscsiTargetPortal
         -- An IP Address and TCP Port pair on which this instance is
         -- listening for connections to its targets.
      iscsiInitiatorPortal
         -- An IP Address from which this instance can make connections
         -- to other targets.
      iscsiSession
         -- An active iSCSI session between an initiator and a target.
         -- The session's direction may be Inbound (outside initiator to
         -- our target) or Outbound (our initiator to an outside target).
         iscsiConnection
            -- An active TCP connection within an iSCSI session
      iscsiTarget
         -- An iSCSI target to which this iSCSI instance is providing
         -- access.
         iscsiAccessList
            -- A list of initiators that are allowed access to this
            -- target.
      iscsiInitiator
         -- An iSCSI initiator, used by this iSCSI instance to access
         -- iSCSI targets.

   An Instance can contain Initiators, Targets, or both.  Multiple
   InitiatorPortals and TargetPortals may be present; the MIB assumes
   that any Target may be accessed via any TargetPortal, although other
   access controls not reflected in the MIB might limit this.

Internet Draft                  iSCSI MIB                   October 2001


   Logical Units and LUNs are SCSI-level entities, which will be covered
   in a separate SCSI MIB.

6.2.  iSCSI MIB Table Structure

   Each iSCSI "object" is comprised of one or more tables: an attributes
   table, and zero or more statistics tables which augment the
   attributes table.  Since iSCSI is an evolving standard, it is much
   cleaner to separate statistics and attributes into separate tables,
   instead of putting them all into the same table.  This allows
   attributes and statistics to be added independently, without mixing
   them and making them appear messy.  In a few cases, there are
   multiple categories of statistics that will likely grow; in this
   case, an object will contain multiple statistics tables.

   iscsiObjects
     iscsiDescriptors
     iscsiInstance
       iscsiInstanceAttributesTable
       iscsiInstanceSsnErrorStatsTable
         -- Counts abnormal session terminations
     iscsiTargetPortal
       iscsiTgtPortalAttributesTable
     iscsiInitiatorPortal
       iscsiIntrPortalAttributesTable
     iscsiSession
       iscsiSessionAttributesTable
       iscsiSessionStatsTable
         -- Performance-related counts (total requests, responses, bytes)
       iscsiSessionCxnErrorStatsTable
         -- Counts digest errors, connection errors, etc.
     iscsiConnection
       iscsiConnectionAttributesTable
     iscsiTarget
       iscsiTargetAttributesTable
       iscsiTargetLoginStatsTable
         -- Counts successful and unsuccessful logins
       iscsiTargetLogoutStatsTable
         -- Counts normal and abnormal logouts
     iscsiAccessList
       iscsiAccessListAttributesTable
     iscsiInitiator
       iscsiInitiatorAttributesTable
       iscsiInitiatorLoginStatsTable
         -- Counts successful and unsuccessful logins
       iscsiInitiatorLogoutStatsTable
         -- Counts normal and abnormal logouts

Internet Draft                  iSCSI MIB                   October 2001


   Note that this MIB does not attempt to count everything that could be
   counted; it is designed to include only those counters that would be
   useful for identifying performance, security, and fault problems from
   a management station.

6.3.  iscsiInstance

   The iscsiInstanceAttributesTable is the primary table of the iSCSI
   MIB.  Every table entry in this MIB is "owned" by exactly one iSCSI
   instance; all other table entries in the MIB include this table's
   index as their primary index.

   Most implementations will include just one iSCSI instance row in this
   table.  However, this table exists to allow for multiple virtual
   instances.  For example, many IP routing products now allow multiple
   virtual routers.  The iSCSI MIB has the same premise; a large system
   could be "partitioned" into multiple, distinct virtual systems.

   This also allows a single SNMP agent to represent multiple
   subsystems, perhaps a set of stackable devices, each of which have
   one or even more instances.  In an iSCSI host, it allows multiple
   vendors' implementations to co-exist under a single SNMP agent; each
   could have its own instance.

   A scalar predecessor of the table called the iscsiInstanceNumber
   denotes the number of instances or rows in the
   iscsiInstanceAttributesTable. Each row also contains similar "Number"
   or instance counts for the various rows of the sub-tables that are
   derived from this table.

   The instance attributes include the iSCSI vendor and version, as well
   as information on the last target or initiator at the other end of a
   session that caused a session failure.

   The iscsiInstanceSsnErrorStatsTable augments the attributes table,
   and provides statistics on session failures due to digest,
   connection, or iSCSI format errors.


6.4.  iscsiTargetPortal

   The iscsiTargetPortalAttributesTable lists local sockets on which the
   iSCSI instance is listening for incoming connections to its targets.
   This table contains the local IP address, TCP (or other protocol)
   port, and IP protocol (for now, just TCP) on which the socket is
   listening.  It also includes a portal group aggregation tag; iSCSI
   target ports within this instance sharing the same tag can contain
   connections within the same session.



Bakke, Muchow              Expires April 2002                   [Page 6]


Internet Draft                  iSCSI MIB                   October 2001


   This table will usually be empty for iSCSI instances that contain
   only initiators (such as iSCSI host driver implementations).

6.5.  iscsiInitiatorPortal

   The iscsiInitiatorPortalAttributesTable lists the IP addresses from
   which the iSCSI instance may initiate connections to other targets.
   Each entry in this table contains a local IP address and IP protocol
   (for now, just TCP), and a portal group aggregation tag, indicating
   which portals an initiator may use together within a multiple-
   connection session.

   This table will usually be empty for iSCSI instances that contain
   only targets (such as most iSCSI devices).

6.6.  iscsiSession

   The iscsiSessionAttributesTable contains a set of rows that list the
   sessions known to be existing locally for each iSCSI instance.

   The session type for each session indicates whether the session is
   used for normal SCSI commands or for discovery using the SendTargets
   text command.

   The session direction for each session indicates whether it is an
   Inbound Session or an Outbound Session.  Inbound sessions are from
   some other initiator to a target within this iSCSI instance; Outbound
   sessions are from our initiator to a target outside this iSCSI
   instance.

   An inbound session may be correlated with its local target using the
   iscsiSsnTarget attribute of the session; the InitiatorName indicates
   the "other end", in some other entity.

   Similarly, an outbound session may be associated with its local
   initiator using the iscsiSsnInitiator; in this case, the TargetName
   indicates the other end.

   Many attributes may be negotiated when starting an iSCSI session.
   Most of these attributes are included in the session object.

   Some attributes, such as the integrity and authentication schemes,
   have some standard values which can be extended by vendors to include
   their own schemes.  These contain an object identifier, rather than
   the expected enumerated type, to allow these values to be extended by
   other MIBs, such as a enterprise MIBs.

   The iscsiSessionStatsTable includes statistics related to

Internet Draft                  iSCSI MIB                   October 2001


   performance; counting iSCSI data bytes and PDUs.

   For implementations that support error recovery without terminating a
   session, the iscsiSessionCxnErrorStatsTable contains counters for the
   numbers of digest and connection errors that have occurred within the
   session.

6.7.  iscsiConnection

   The iscsiConnectionAttributesTable contains a list of active
   connections within each session.  It contains the IP addresses and
   TCP (or other protocol) ports of both the local and remote side of
   the connection.  These may be used to locate other connection-related
   information and statistics in the TCP MIB [RFC 2012].

   The attributes table also contains a connection state.  This state is
   not meant to directly map to the state tables included within the
   iSCSI specification; they are meant to be simplified, higher-level
   definitions of connection state that provide information more useful
   to a user or network manager.

   No statistics are kept for connections.

6.8.  iscsiTarget

   The iscsiTargetAttributesTable contains a list of iSCSI targets which
   may be accessed through the iSCSI instance.  This table contains the
   target's iSCSI Name, alias string, and some attributes used to
   indicate the last failure that was (or should have been) sent as a
   notification or trap.

   This table is augmented by the iscsiTargetLoginStatsTable and the
   iscsiTargetLogoutStatsTable, which count the numbers of normal and
   abnormal logins and logouts to this target.

6.9.  iscsiAccessList

   The iscsiAccessListAttributesTable contains an entry for each
   initiator that is allowed to access the target under which it
   appears.  If a target allows access to any initiator, an
   AccessListAttributesEntry with the initiator's iSCSI name should be
   used.

   This table does not cover all possible access control schemes that a
   vendor could implement.  If access to an initiator cannot be
   determined just by its iSCSI name, an implementation may either
   include a single entry per target with the initiator name "iscsi", or
   may choose to place no entries in this table.

Internet Draft                  iSCSI MIB                   October 2001


   No statistics are provided for access list entries.

6.10.  iscsiInitiator

   The iscsiInitiatorAttributesTable contains a list of iSCSI initiators
   which are used by this iSCSI instance to access targets.  Most
   implementations will include a single entry in this table, regardless
   of the number of physical interfaces the initiator may use.  This
   table's attributes include the initiator's iSCSI name and alias
   string.

   This table is augmented by the iscsiInitiatorLoginStatsTable and the
   iscsiInitiatorLogoutStatsTable, which count the numbers of normal and
   abnormal logins and logouts to this target.

6.11.  IP Addresses and TCP Port Numbers

   The IP addresses in this MIB are represented by two attributes, one
   of type InetAddressType, and the other of type InetAddress.  These
   are taken from [IPV6MIB], which is an update to [RFC2851] specifying
   how to support addresses that may be either IPv4 or IPv6.

   The TCP port numbers that appear in a few of the structures are
   described as simply port numbers, with a protocol attribute
   indicating whether they are TCP ports, or something else.  This will
   allow the MIB to be compatible with iSCSI over transports other than
   TCP in the future.

6.12.  Descriptors: Using OIDs in Place of Enumerated Types

   The iSCSI MIB has a few attributes, such as the authentication and
   digest method attributes, where an enumerated type would work well,
   except that an implementation may need to extend the attribute and
   add types of its own.  To make this work, the MIB defines a set of
   object identities within iscsiDescriptors.  Each of these object
   identities is basically an enumerated type.

   Attributes that make use of these object identities have a value
   which is an OID instead of an enumerated type.  These OIDs can either
   indicate the object identities defined in this MIB, or object
   identities defined elsewhere, such as in an enterprise MIB.  Those
   implementations that add their own authentication and digest methods
   should also define a corresponding object identity for each of these
   methods within their own enterprise MIB, and return its OID whenever
   one of these attributes is using that method.

Internet Draft                  iSCSI MIB                   October 2001


6.13.  Notifications

   Three notifications are provided.  One is sent by an initiator
   detecting a critical login failure; another is sent by a target
   detecting a critical login failure, and the third is sent upon a
   session being terminated due to an abnormal connection or digest
   failure.  Critical failures are defined as those that may expose
   security-related problems that may require immediate action, such as
   failures due to authentication, authorization, or negotiation
   problems.  Attributes in the initiator, target, and instance objects
   provide the information necessary to send in the notification, such
   as the initiator or target name and IP address at the other end that
   may have caused the failure.

   To avoid sending an excessive number of notifications due to multiple
   errors counted, an SNMP agent implementing the iSCSI MIB should not
   send more than three iSCSI notifications in any 10-second period.

   The 3-in-10 rule was chosen because one notification every three
   seconds was deemed often enough, but should two or three different
   notifications happen at the same time, it would not be desirable to
   suppress them.  Three notifications in ten seconds is a happy medium,
   where a short burst of notifications is allowed, without inundating
   the network and/or trap host with a large number of notifications.

8.  Security Considerations

   There are no management objects defined in this MIB that have a MAX-
   ACCESS clause of read-write and/or read-create.  So, if this MIB is
   implemented correctly, then there is no risk that an intruder can
   alter or create any management objects of this MIB via direct SNMP
   SET operations.

   Information gleaned from this MIB could be used to make connections
   to the iSCSI targets it represents.  However, it is the responsbility
   of the initiators and targets involved to authenticate each other to
   ensure that an inappropriately advertised or discovered initiator or
   target does not compromise their security.  These issues are
   discussed in [ISCSI].

   SNMPv1 by itself is not a secure environment.  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.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [RFC2574] and the View-
   based Access Control Model RFC 2575 [RFC2575] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, 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.
