Internet Draft iSCSI MIB March 2003
1. Introduction
This document defines a MIB for iSCSI [ISCSI], used to manage devices
which implement the iSCSI protocol.
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. Relationship to Other MIBs
The iSCSI MIB is layered between the SCSI MIB [SCSI-MIB] (work in
progress) and the TCP MIB [RFC2012], and makes use of the IPS
Identity Authentication MIB [AUTH-MIB] (work in progress). Here is
how the MIBs are related:
SCSI MIB Each iscsiNode, whether it has an initiator role, target
role, or both, is related to one SCSI device within the
SCSI MIB. The iscsiNodeTransportType attribute points to
the SCSI transport object within the SCSI MIB, which in
turn contains an attribute that points back to the
iscsiNode. In this way, a management station can navigate
between the two MIBs.
TCP MIB Each iSCSI connection is related to one transport-level
connection. Currently, iSCSI uses only TCP; the iSCSI
connection is related to a TCP connection using its normal
(protocol, source address, source port, destination
address, destination port) 5-tuple.
AUTH MIB Each iSCSI node that serves a target role can have a list
of authorized initiators. Each of the entries in this list
points to an identity within the IPS Identity
Authentication MIB that will be allowed to access the
target. iSCSI nodes that serve in an initiator role can
Bakke, Muchow Expires August 2003 [Page 3]
Internet Draft iSCSI MIB March 2003
also have a list of authorized targets. Each of the
entries in this list points to an identity within the Auth
MIB to which the initiator should attempt to establish
sessions. The Auth MIB includes information used to
identify initiators and targets by their iSCSI name, IP
address, and/or credentials.
4. Discussion
This MIB structure supplies configuration, fault, and statistics
information for iSCSI devices [ISCSI]. It is structured around the
well-known iSCSI objects, such as targets, initiators, sessions,
connections, and the like.
This MIB may also be used to configure access to iSCSI targets, by
creating iSCSI Portals and authorization list entries.
It is worthwhile to note that this is an iSCSI MIB and as such
reflects only iSCSI objects. This MIB does not contain information
about the SCSI-layer attributes of a device. The SCSI MIB, currently
under development, is related to the iSCSI MIB and contains the SCSI
information about a device.
The iSCSI MIB consists of several "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 MIB table structure
within the objects.
4.1. 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.
iscsiPortal
-- An IP address used by this instance
iscsiTargetPortal
-- Contains portal information relevant when the portal
-- is used to listen for connections to its targets.
iscsiInitiatorPortal
-- Contains portal information relevant when the portal
-- is used to initiate connections to other targets.
iscsiNode
-- An iSCSI node can act as an initiator, a target, or both.
-- Contains generic (non-role-specific) information.
Bakke, Muchow Expires August 2003 [Page 4]
Internet Draft iSCSI MIB March 2003
iscsiTarget
-- Target-specific iSCSI node information.
iscsiTgtAuth
-- A list of initiator identities that are allowed
-- access to this target.
iscsiInitiator
-- Initiator-specific iSCSI node information.
iscsiIntrAuth
-- A list of target identities to which this initiator
-- is configured to establish sessions.
iscsiSession
-- An active iSCSI session between an initiator and 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
An iSCSI Node can be an initiator, a target, or both. The iSCSI
Node's portals may be used to initiate connections (initiator) or
listen for connections (target), depending on wither the iSCSI Node
is acting as an initiator or target. The iSCSI MIB assumes that any
target may be accessed via any portal that can take on a target role,
although other access controls not reflected in the MIB might limit
this.
4.2. iSCSI MIB Table Structure
Each iSCSI object exports 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
provide statistics and attributes as separate tables, allowing
attributes and statistics to be added independently. In a few cases,
there are multiple categories of statistics that will likely grow; in
this case, an object will contain multiple statistics tables.

iscsiSessionAttributesTable
iscsiSessionStatsTable
-- Performance-related counts (requests, responses, bytes)
iscsiSessionCxnErrorStatsTable
-- Counts digest errors, connection errors, etc.
iscsiConnection
iscsiConnectionAttributesTable
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.
4.3. 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 proxy for multiple
subsystems, perhaps a set of stackable devices, each of which have
one or even more instances.
Bakke, Muchow Expires August 2003 [Page 6]
Internet Draft iSCSI MIB March 2003
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.
4.4. iscsiPortal
The iscsiPortalAttributesTable lists iSCSI portals that can either be
used to listen for connections to targets, or initiate connections to
other targets, or both.
Each entry in the table includes an IP address (either v4 or v6), and
a transport protocol (currently only TCP is defined). Each entry
that fulfills an initiator portal role has a corresponding entry in
the iscsiInitiatorPortal table; each entry that has a target portal
role has an entry in the iscsiTargetPortal table. Each portal that
serves both roles has a corresponding entry in each table.
Portal entries, along with their initiator and target portal
counterparts, may be created and destroyed through this MIB by a
management station.
When creating a new portal entry, an iscsiPortal is first created,
then the iscsiTargetPortal, iscsiInitiatorPortal, or both.
Attributes are added during creation, and may not be subsequently
modified. Creating an iscsiTargetPortal will cause the
implementation to start listening for iSCSI connections on the
portal. Creating an iscsiInitiatorPortal will not necessarily cause
connections to be established; it is left to the implementation
whether and when to make use of the portal.
When deleting a portal entry, all connections associated with that
portal entry are terminated. The implementation may either terminate
the connection immediately, or request a clean shutdown as specified
in [ISCSI]. An outbound connection (when an iscsiInitiatorPortal is
deleted) matches the portal if its iscsiCxnLocalAddr matches the
iscsiPortalAddr. An inbound connection (when an iscsiTargetPortal is
deleted) matches the portal if both its iscsiCxnLocalAddr matches the
iscsiPortalAddr, and the iscsiCxnLocalPort matches the
iscsiTargetPortalPort.
Individual attributes within a portal, initiatorPortal, or
targetPortal entry may not be modified. For instance, changing the IP
address of a portal requires that the portal entries associated with
Bakke, Muchow Expires August 2003 [Page 7]
Internet Draft iSCSI MIB March 2003
the old IP address be deleted, and new entries be created (in either
order).
4.5. iscsiTargetPortal
The iscsiTgtPortalAttributesTable contains target-specific attributes
for iSCSI Portals. Entries in this table use the same indices as
their corresponding entries in the iscsiPortalAttributesTable. An
entry in this table is created when the targetTypePortal bit is set
in the iscsiPortalRoles attribute; it is destroyed when this bit is
cleared.
This table contains the TCP (or other protocol) port on which the
socket is listening for incoming connections. It also includes a
portal group aggregation tag; iSCSI target portals within this
instance sharing the same tag can contain connections within the same
session.
This table will be empty for iSCSI instances that contain only
initiators (such as iSCSI host driver implementations).
4.6. iscsiInitiatorPortal
The iscsiIntrPortalAttributesTable contains initiator-specific
attributes for iSCSI Portals. Entries in this table use the same
indices as their corresponding entries in the
iscsiPortalAttributesTable. An entry in this table is created when
the initiatorTypePortal bit is set in the iscsiPortalRoles attribute;
it is destroyed when this bit is cleared.
Each entry in this table contains a portal group aggregation tag,
indicating which portals an initiator may use together within a
multiple-connection session.
This table will be empty for iSCSI instances that contain only
targets (such as most iSCSI devices).
4.7. iscsiNode
The iscsiNodeAttributesTable contains a list of iSCSI nodes, each of
which may have an initiator role, a target role, or both.
This table contains the node's attributes which are common to both
roles, such as its iSCSI Name and alias string. Attributes specific
to initiators or targets are available in the iscsiTarget and
iscsiInitiator objects. Each entry in this table that can fulfill a
target role has a corresponding entry in the iscsiTarget table; each
Bakke, Muchow Expires August 2003 [Page 8]
Internet Draft iSCSI MIB March 2003
entry that fulfills an initiator role has an entry in the
iscsiInitiator table. Nodes such as copy managers that can take on
both roles have a corresponding entry in each table.
This table also contains the login negotiations preferences for this
node. These objects indicate the values this node will offer or
prefer in the operational negotiation phase of the login process.
Each entry in the table also contains a RowPointer to the transport
table entry in the SCSI MIB which this iSCSI node represents.
4.8. iscsiTarget
The iscsiTargetAttributesTable contains target-specific attributes
for iSCSI nodes. Each entry in this table uses the same index values
as its corresponding iscsiNode entry.
This table contains 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.
4.9. iscsiTgtAuthorization
The iscsiTgtAuthAttributesTable contains an entry for each initiator
identifier that will be allowed to access the target under which it
appears. Each entry contains a RowPointer to a user identity in the
IPS Identity Authentication MIB, which contains the name, address,
and credential information necessary to authenticate the initiator.
4.10. iscsiInitiator
The iscsiInitiatorAttributesTable contains a list of initiator-
specific attributes for iSCSI nodes. Each entry in this table uses
the same index values as its corresponding iscsiNode entry.
Most implementations will include a single entry in this table,
regardless of the number of physical interfaces the initiator may
use.
This table is augmented by the iscsiInitiatorLoginStatsTable and the
iscsiInitiatorLogoutStatsTable, which count the numbers of normal and
abnormal logins and logouts from this initiator.
Bakke, Muchow Expires August 2003 [Page 9]
Internet Draft iSCSI MIB March 2003
4.11. iscsiIntrAuthorization
The iscsiIntrAuthAttributesTable contains an entry for each target
identifier to which the initiator is configured to establish a
session.
Each entry contains a RowPointer to a user identity in the IPS
Identity Authentication MIB, which contains the name, address, and
credential information necessary to identify (for discovery purposes)
and authenticate the target.
4.12. iscsiSession
The iscsiSessionAttributesTable contains a set of rows that list the
sessions known to be existing locally for each node in 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. Discovery sessions that do not belong to any
particular node have a node index attribute of zero.
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 the target node under which the session
appears. Outbound sessions are from the initiator node under which
the session appears to a target outside this iSCSI instance.
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 an enterprise MIB.
The iscsiSessionStatsTable includes statistics related to
performance; it counts 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.
Bakke, Muchow Expires August 2003 [Page 10]
Internet Draft iSCSI MIB March 2003
4.13. 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 [RFC2012].
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.
4.14. 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 [RFC3291], which specifies 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.
4.15. 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 the iscsiDescriptors subtree. 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.
Bakke, Muchow Expires August 2003 [Page 11]
Internet Draft iSCSI MIB March 2003
4.16. 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.

6. Security Considerations
There are a number of 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 are the tables and objects and their
sensitivity/vulnerability:
iscsiPortalAttributesTable, iscsiTgtPortalAttributesTable, and
iscsiIntrPortalAttributes table can be used to add or remove IP
addresses to be used by iSCSI.
iscsiTgtAuthAttributesTable entries can be added or removed, to
allow or disallow access to a target by an initiator.
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:
iscsiNodeAttributesTable, iscsiTargetAttributesTable, and
iscsiTgtAuthorization can be used to glean information needed to
make connections to the iSCSI targets this MIB represents.
However, it is the responsibility 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].
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
Bakke, Muchow Expires August 2003 [Page 69]
Internet Draft iSCSI MIB March 2003
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.
