RFC 4544 iSCSI MIB May 2006
1. Introduction
This document defines a MIB module for iSCSI [RFC3720], used to
manage devices that implement the iSCSI protocol.
2. Specification of Requirements
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 RFC 2119 [RFC2119].
3. 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].
4. Relationship to Other MIB Modules
The iSCSI MIB module is normally layered between the SCSI MIB module
[RFC4455] and the TCP MIB module [RFC4022], and makes use of the IP
Storage (IPS) Identity Authentication MIB module [RFC4545]. Here is
how these modules are related:
SCSI MIB Within systems where a SCSI layer is present, each
iscsiNode, whether it has an initiator role, target role,
or both, is related to one SCSI device within the SCSI MIB
module. In this case, the iscsiNodeTransportType attribute
points to the SCSI transport object within the SCSI MIB
module, which in turn contains an attribute that points
back to the iscsiNode. In this way, a management station
can navigate between the two MIB modules. In systems where
a SCSI layer is not present, such as within an iSCSI proxy
device, the iscsiNodeTransportType attribute points to the
appropriate corresponding object within the appropriate
MIB, or is left blank.
Bakke, et al. Standards Track [Page 3]
RFC 4544 iSCSI MIB May 2006
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 module that will be allowed to access
the target. iSCSI nodes that serve in an initiator role
can also have a list of authorized targets. Each of the
entries in this list points to an identity within the Auth
MIB module to which the initiator should attempt to
establish sessions. The Auth MIB module includes
information used to identify initiators and targets by
their iSCSI name, IP address, and/or credentials.
This MIB module imports objects from RFCs 2578 [RFC2578], 2579
[RFC2579], 2580 [RFC2580], and 3411 [RFC3411]. It also imports
textual conventions from the INET-ADDRESS-MIB [RFC4001].
5. Relationship to SNMP Contexts
Each non-scalar object in the iSCSI MIB module is indexed first by an
iSCSI Instance. Each instance is a collection of nodes, portals,
sessions, etc., that can define a physical or virtual partitioning of
an iSCSI-capable device. The use of an instance works well with
partitionable or hierarchical storage devices and fits in logically
with other management schemes. Instances do not replace SNMP
contexts, however they do provide a very simple way to assign a
virtual or physical partition of a device to one or more SNMP
contexts, without having to do so for each individual node, portal,
and session row.
6. Discussion
This MIB module structure supplies configuration, fault, and
statistics information for iSCSI devices [RFC3720]. It is structured
around the well-known iSCSI objects, such as targets, initiators,
sessions, connections, and the like.
This MIB module may also be used to configure access to iSCSI
targets, by creating iSCSI Portals and authorization list entries.
Bakke, et al. Standards Track [Page 4]
RFC 4544 iSCSI MIB May 2006
It is worthwhile to note that this is an iSCSI MIB module and as such
reflects only iSCSI objects. This module does not contain
information about the SCSI-layer attributes of a device. If a SCSI
layer is present, the SCSI MIB module, currently under development,
may be used to manage SCSI information for a device.
The iSCSI MIB module 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 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.
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.
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.
Bakke, et al. Standards Track [Page 5]
RFC 4544 iSCSI MIB May 2006
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 whether the iSCSI node
is acting as an initiator or target. The iSCSI MIB module 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
module might limit this.
6.2. iSCSI MIB Table Structure
Each iSCSI object exports 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.

iscsiSessionCxnErrorStatsTable

iscsiConnection
iscsiConnectionAttributesTable
Note that this module 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 module. Every table entry in this module is "owned" by exactly
one iSCSI instance; all other table entries in the module 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 module 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 has one
or even more instances.
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. iscsiPortal
The iscsiPortalAttributesTable lists iSCSI portals that can be used
to listen for connections to targets, to initiate connections to
other targets, or to do both.
Bakke, et al. Standards Track [Page 7]
RFC 4544 iSCSI MIB May 2006
Each row in the table includes an IP address (either v4 or v6), and a
transport protocol (currently only TCP is defined). Each portal may
have additional attributes, depending on whether it is an initiator
portal, a target portal, or both. Initiator portals also have portal
tags; these are placed in corresponding rows in the
iscsiIntrPortalAttributesTable. Target portals have both portal tags
and ports (e.g., TCP listen ports if the transport protocol is TCP);
these are placed in rows in the iscsiTgtPortalAttributesTable.
Portal rows, along with their initiator and target portal
counterparts, may be created and destroyed through this MIB module by
a management station. Rows in the initiator and target portal tables
are created and destroyed automatically by the agent, whenever a row
is created or destroyed in the iscsiPortalAttributesTable, or if the
value of iscsiPortalRoles changes. Attributes in these tables may
then be modified by the management station if the agent
implementation allows.
When created by a management station, the iscsiPortalRoles attribute
is used to control row creation in the initiator and target portal
tables. Creating a row with the targetTypePortal bit set in
iscsiPortalRoles will cause the implementation to start listening for
iSCSI connections on the portal. Creating a row with the
initiatorTypePortal bit set in iscsiPortalRoles will not necessarily
cause connections to be established; it is left to the implementation
whether and when to make use of the portal. Both bits may be set if
the portal is to be used by both initiator and target nodes.
When deleting a row in the iscsiPortalAttibutesTable, all connections
associated with that row are terminated. The implementation may
either terminate the connection immediately or request a clean
shutdown as specified in [RFC3720]. 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 its
iscsiCxnLocalAddr matches the iscsiPortalAddr, and its
iscsiCxnLocalPort matches the iscsiTargetPortalPort.
Individual objects within a row in this table may not be modified
while the row is active. For instance, changing the IP address of a
portal requires that the rows associated with the old IP address be
deleted, and new rows be created (in either order).
Bakke, et al. Standards Track [Page 8]
RFC 4544 iSCSI MIB May 2006
6.5. iscsiTargetPortal
The iscsiTgtPortalAttributesTable contains target-specific attributes
for iSCSI portals. Rows in this table use the same indices as their
corresponding rows in the iscsiPortalAttributesTable, with the
addition of iscsiNodeIndex.
Rows in this table are created when the targetTypePortal bit is set
in the iscsiPortalRoles attribute of the corresponding
iscsiPortalAttributesEntry; they are 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).
Many implementations use the same target portal tag and protocol port
for all nodes accessed via a portal. These implementations will
create a single row in the iscsiTgtPortalAttributeTable, with an
iscsiNodeIndex of zero.
Other implementations do not use the same tag and/or port for all
nodes; these implementations will create a row in this table for each
(portal, node) tuple, using iscsiNodeIndex to designate the node for
this portal tag and port.
6.6. iscsiInitiatorPortal
The iscsiIntrPortalAttributesTable contains initiator-specific
objects for iSCSI portals. Rows in this table use the same indices
as their corresponding entries in the iscsiPortalAttributesTable. A
row in this table is created when the initiatorTypePortal bit is set
in the iscsiPortalRoles attribute; it is destroyed when this bit is
cleared.
Each row 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).
Bakke, et al. Standards Track [Page 9]
RFC 4544 iSCSI MIB May 2006
Many implementations use the same initiator tag for all nodes
accessing targets via a given portal. These implementations will
create a single row in iscsiIntrPortalAttributeTable, with an
iscsiNodeIndex of zero.
Other implementations do not use the same tag and/or port for all
nodes; these implementations will create a row in this table for each
(portal, node) tuple, using iscsiNodeIndex to designate the node for
this portal tag and port.
6.7. 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 that 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 row in this table that can fulfill a
target role has a corresponding row in the iscsiTarget table; each
entry that fulfills an initiator role has a row in the iscsiInitiator
table. Nodes such as copy managers that can take on both roles have
a corresponding row 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.
For most implementations, each entry in the table also contains a
RowPointer to the transport table entry in the SCSI MIB module that
this iSCSI node represents. For implementations without a standard
SCSI layer above iSCSI, such as an iSCSI proxy or gateway, this
RowPointer can point to a row in an implementation-specific table
that this iSCSI node represents.
6.8. 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.
This table is augmented by the iscsiTargetLoginStatsTable and the
iscsiTargetLogoutStatsTable, which count the numbers of normal and
abnormal logins and logouts to this target.
Bakke, et al. Standards Track [Page 10]
RFC 4544 iSCSI MIB May 2006
6.9. 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 Authorization MIB module, which contains the name, address, and
credential information necessary to authenticate the initiator.
6.10. 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.
6.11. 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
Authorization MIB module, which contains the name, address, and
credential information necessary to identify (for discovery purposes)
and authenticate the target.
6.12. 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.
Bakke, et al. Standards Track [Page 11]
RFC 4544 iSCSI MIB May 2006
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 that 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 MIB modules, such as an enterprise MIB module.
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.
6.13. 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 sides of
the connection. These may be used to locate other connection-related
information and statistics in the TCP MIB module [RFC4022].
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.
6.14. IP Addresses and TCP Port Numbers
The IP addresses in this module are represented by two attributes,
one of type InetAddressType, and the other of type InetAddress.
These are taken from [RFC4001], which specifies how to support
addresses that may be either IPv4 or IPv6.
Bakke, et al. Standards Track [Page 12]
RFC 4544 iSCSI MIB May 2006
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 module to be compatible with iSCSI over transports other
than TCP in the future.
6.15. Descriptors: Using OIDs in Place of Enumerated Types
The iSCSI MIB module has a few attributes, namely, the 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, this MIB module 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 that
is an Object Identifier (OID) instead of an enumerated type. These
OIDs can indicate either the object identities defined in this module
or object identities defined elsewhere, such as in an enterprise MIB
module. Those implementations that add their own digest methods
should also define a corresponding object identity for each of these
methods within their own enterprise MIB module, and return its OID
whenever one of these attributes is using that method.
6.16. 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 module
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 10 seconds is a happy medium,
Bakke, et al. Standards Track [Page 13]
RFC 4544 iSCSI MIB May 2006
where a short burst of notifications is allowed, without inundating
the network and/or notification host with a large number of
notifications.

8. 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
iscsiIntrPortalAttributesTable 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 module 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
[RFC3720].
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, et al. Standards Track [Page 79]
RFC 4544 iSCSI MIB May 2006
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.
9. IANA Considerations
The IANA has assigned a MIB OID number under the mib-2 branch for the
ISCSI-MIB.
