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 defines objects for managing the configuration,
monitoring and control of Physical Units (PUs) and Logical Units
(LUs) in an SNA environment. PUs and LUs are two types of Network
Addressable Units (NAUs) in the logical structure of an SNA network.
NAUs are the origination or destination points for SNA data streams.
This memo identifies managed objects for PU Type 1.0, 2.0 and Type
2.1 and LU Type 0, 1, 2, 3, 4, 7. The generic objects defined here
can also be used to manage LU 6.2 and any LU-LU session. The SNA
terms and overall architecture are documented in [1].

2. The SNMPv2 Network Management Framework

The SNMPv2 Network Management Framework consists of four major
components. They are:

o RFC1442 [2] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.

o STD 17, RFC1213 [3] defines MIB-II, the core set of
managed objects for the Internet suite of protocols.

o RFC1445 [4] which defines the administrative and other
architectural ASPects of the framework.

o RFC1448 [5] which defines the protocol used for network
Access to managed objects.

The Framework permits new objects to be defined for the purpose of
eXPerimentation and evaluation.

2.1. Object Definitions

Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI (RFC1442 [2]). In particular, each object type
is named by an OBJECT IDENTIFIER, an administratively assigned name.
The object type together with an object instance serves to uniquely
identify a specific instantiation of the object. For human
convenience, we often use a textual string, termed the descriptor, to
refer to the object type.

3. Overview

This document identifies the proposed set of objects for managing the
configuration, monitoring and control of Physical Units (PUs) and
Logical Units (LUs) in an SNA environment. In this document, the name
"Node" is used to describe SNA Node Type 1.0, 2.0 and Type 2.1 and
the name "LU" is used to describe Logical Unit of Type 0, 1, 2, 3, 4,
7 and 6.2. Note however that only objects common to all PU and LU
types are covered here and LU 6.2 specific objects are not included
in this MIB module.

Highlights of the management functions supported by the SNANAU MIB
module include the following:

o Creation/deletion of Nodes and LUs via the RowStatus objects
in the snaNodeAdminTable and in the snaLuAdminTable.

o Creation/deletion of table entries associating Node instances
with link instances via the RowStatus object in the
snaNodeLinkAdminTable

o Activation/Deactivation of Nodes via the AdminState object in
the snaNodeAdminTable

o Deactivation of sessions via the AdminState object in the
snaLuSessnTable

o Monitoring and modification of parameters related to Nodes, LUs,
and Node/link associations

o Monitoring of session operational parameters

o PU2.0 operational statistics

o Session operational statistics

o RTM statistics

o Traps for:
+ Node state change
+ Node activation failure
+ LU state change
+ LU session BIND failure

This MIB module does not support:

o creation of links,

o activation or deactivation of LUs, nor

o activation of sessions.

3.1. Applying MIB II to managing SNA NAUs

This section identifies how MIB II objects, specifically the MIB II
system group will be used in SNMP-based management of SNA NAUs. The
MIB II system group applies to the SNMP Agent. The following object
is from the MIB II system group:

sysUpTime: clock in the SNMP Agent/proxy-Agent; expressed in
TimeTicks (1/100s of a seconds).

This MIB module uses the TimeStamp TEXTUAL-CONVENTION which is
defined in the SNMPv2 Textual Conventions (RFC1443 [6]) as "the
value of MIB II's sysUpTime object when a specific occurrence
happens." The specific occurrences related to SNA NAU management are
defined in this MIB module.

3.2. SNANAU MIB Structure

The SNANAU MIB module contains three groups of objects:

o snaNode - objects related to Node configuration, monitoring and
control.

o snaLu - objects related to LU definition, monitoring and
control.

o snaMgtTools - objects related to specific management tools well
known in SNA environment.

These groups are described below in more detail.

The objects related to PUs and LUs are organized into two types of
tables: the Admin and Oper tables.

The "Admin" table contains parameters which are used by a Management
Station to affect the operation of the SNA service. Some parameters
are used to initialize and configure the SNA service at the next
startup, while others can take effect immediately. A Management
Station can dynamically define SNA resources (PUs, LUs) by creating
new entries in the Admin table. It uses a special object, AdminState,

to control the desired state of a defined PU or LU Session resource.
Note that this MIB does not allow the manipulation of an LU's
operational state.

The "Oper" table is an extension (augment) of the corresponding Admin
table. It contains objects which correspond to the values of
parameters currently used by the SNA system.

3.2.1. snaNode group

The snaNode group consists of the following tables:

1) snaNodeAdminTable - This table contains objects which describe
the configuration parameters of an SNA Node. Link-specific
configuration objects are contained in a separate MIB module
(e.g., the SNA DLC MIB module) corresponding to link type.
Entries in this table can be created, modified and deleted by
either an Agent or a Management Station. The snaNodeAdminRowStatus
object describes the status of an entry and is used to change the
status of that entry.

The snaNodeAdminState object describes the desired operational
state of a Node and is used to change the operational state of a
Node.

How an Agent or a Management Station oBTains the initial value of
each object at creation time is an implementation specific issue
not addressed in this memo.

For each entry in the snaNodeAdminTable, there is a corresponding
entry in the snaNodeOperTable. While the objects in this table
describe the desired or configured operational values of the SNA
Node, the actual runtime values are contained in snaNodeOperTable.

2) snaNodeOperTable - Each row contains runtime and operational
state variables for a Node. It is an extension of
snaNodeAdminTable and as such uses the same index. The rows in
this table are created by an Agent as soon as the entry in the
Admin Table become 'active'. The entries in this table cannot be
modified by a Management Station.

3) snaPu20StatsTable - Each row contains statistics variables
(counters) for a PU 2.0. The entries in this table are indexed by
snaNodeAdminIndex. The rows in this table are created by an Agent
as soon as the corresponding entry in the snaNodeAdminTable
becomes 'active'.

4) snaNodeLinkAdminTable - This table contains all references to
link- specific tables. If a Node is configured with multiple
links, then it will have multiple entries in this table. The
entries in this table can be generated initially, after startup of
SNA service, by the Agent which uses information from Node
configuration file. Subsequent modifications of parameters,
creation of new Node link entries and deletion of entries is
possible. The modifications to this table can be saved in the Node
configuration file for the next startup (i.e., restart or next
initialization) of SNA service, but the mechanism for this
function is not defined in this memo. Each entry contains the
configuration information that associates a Node instance to one
link instance. The entries are indexed by snaNodeAdminIndex and
snaNodeLinkAdminIndex.

5) snaNodeLinkOperTable - This table contains all references to
link- specific tables for operational parameters. If the Node is
configured for multiple links, then it will have multiple entries
in this table. This table augments the snaNodeLinkAdminTable.

6) snaNodeTraps - Two traps are defined for Nodes. The
snaNodeStateChangeTrap indicates that the operational state of a
Node has changed. The snaNodeActFailTrap indicates the failure of
ACTPU received from host.

3.2.2. snaLu group

The snaLu group consists of the following tables:

1) snaLuAdminTable - Table containing LU configuration
information. The rows in this table can be created and deleted by
a Management Station. Only objects which are common to all types
of LUs are included in this table. The entries are indexed by Node
and LU indices.

2) snaLuOperTable - Table containing dynamic runtime information
and control variables relating to LUs. Only objects which are
common to all types of LUs are included in this table. This table
augments the snaLuAdminTable.

3) snaLuSessnTable - This is a table containing objects which
describe the operational state of LU-LU sessions. Only objects
which are common to all types of LU-LU sessions are included in
this table. When a session's snaLuSessnOperState value changes to
entry in the session table is created by the Agent. When the
snaLuSessionOperState value changes to will be removed from the
session table by the Agent. Entries are indexed by Node, local
LU, remote LU and session indices.

4) snaLuSessnStatsTable - Table containing dynamic statistics
information relating to LU-LU sessions. The entries in this table
augment the entries in the snaLuSessnTable and cannot be created
by a Management Station.

5) snaLuTraps - Two traps are defined for LUs. The
snaLuStateChangeTrap indicates that the operational state of an LU
has changed. The snaLuSessnBindFailTrap indicates the failure of
a BIND request.

3.2.3. snaMgtTools group

This is an optional group. The snaMgtTools group consists of the
following table:

1) snaLuRtmTable - Each row contains Response Time Monitor (RTM)
variables for an LU. The table is indexed by Node and LU indices.
Entries correspond to LU 2 entries in the snaLuAdminTable. A
Management Station can read collection of RTM statistics for a
given LU.

3.2.4. Conformance statement

Compliance of the SNMPv2 management entity to the SNANAU MIB is
defined in terms of following conformance units called groups.

Unconditionally mandatory groups: snaNodeGroup, snaLuGroup,
snaSessionGroup.

Conditionally mandatory groups: snaPu20Group - mandatory only for
those entities which implement PU type 2.0. The snaMgtToolsRtmGroup
- mandatory only for those entities which implement LU type 2 and
RTM.

Refinement of requirements for objects access: an Agent which does
not implement row creation for snaNodeAdminTable
snaNodeLinkAdminTable and snaLuAdminTable must at least support
object modification requests (i.e., read-write access instead of
read-create).

3.3. SNANAU MIB special feature

This section describes the mechanism used for row creation in the
Admin tables and also presents critical state transitions for PUs,
LUs and Sessions.

3.3.1. Row Creation mechanism

The row creation mechanism for the Admin tables in this MIB module is
based on the use of the RowStatus object. Restriction of some
operations for specific tables are described in each table. In
particular, before accepting the 'destroy' value for an entry, an
Agent has to verify the operational state of the corresponding entry
in the Oper table.

3.3.2. State Diagrams

The following state diagram models the state transitions for Nodes.
When a row is created by a Management Station, an Agent creates the
Oper table entry for that Node with the OperState equal to
'inactive'. An Agent cannot accept any operations for that Node until
the RowStatus is set to 'active'.

OperState -> inactive active waiting stopping
--------------I--------------I--------------I--------------I---------
AdminState: I I I I
active I active I active I waiting I no
I I I I
inactive I inactive I stopping I inactive I stopping
I or inactive I

The following state diagram models state transitions for Sessions.
When a session goes to the 'unbound' state [1], the corresponding
entry will be removed from the Session table by the Agent.

OperState -> unbound pendingBind bound pendingUnbind
--------------I--------------I--------------I----------I--------------
AdminState: I I I I
bound I no I no I no I no
I I I I
unbound I unbound I unbound I unbound I unbound

snaNodeAdminTable OBJECT-TYPE
SYNTAX SEQUENCE OF SnaNodeAdminEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table contains objects which describe the
configuration parameters for an SNA Node. Link
specific configuration objects are contained in
a separate MIB module (e.g., SNA DLC MIB)

corresponding to the link type.
The table snaNodeAdminLinkTable contains objects
which identify the relationship between node instances
and link instances.

The entries (i.e., rows) in this table can be created
by either an Agent or a Management Station.
The Management Station can do this through setting
the appropriate value in the snaNodeAdminRowStatus.

The snaNodeAdminRowStatus object describes the
status of an entry and is used to change the status
of an entry. The entry is deleted by an Agent based
on the value of the snaNodeAdminRowStatus.

The snaNodeAdminState object describes the desired
operational state of a Node and is used to change the
operational state of a Node. For example, such
information may be obtained from a configuration file.

How an Agent or a Management Station obtains the
initial value of each object at creation time is an
implementation specific issue.

For each entry in this table, there is a corresponding
entry in the snaNodeOperTable.
While the objects in this table describe the desired
or configured operational values of the SNA Node, the
actual runtime values are contained in
snaNodeOperTable."

(this is the default),
demand (3) - only when LU is requested by application,
or
onlyMS (4) - by a Management Station only.

A write operation to this object may immediately
change the operational value reflected
in snaNodeOperEnablingMethod depending
on the Agent implementation. If the Agent
implementation accepts immediate changes, then the
behavior of the Node changes immediately and not only
after the next system startup of the SNA services.
An immediate change may only apply when the
current value 'demand (3)' is changed to 'onlyMS (4)'
and vice versa."

DESCRIPTION
"The value indicates the desired default method
used to deactivate LUs for this Node
For LU6.2s, 'unbind(1)' is the only valid value.

unbind(1) - terminate the LU-LU session by sending
an SNA UNBIND request.
termself(2) - terminate the LU-LU session by sending
an SNA TERM-SELF (Terminate Self) request on
the SSCP-LU session. The SSCP will inform the
remote session LU partner to send an UNBIND
request to terminate the session.
rshutd(3) - terminate the LU-LU session by sending
an SNA RSHUTD (Request ShutDown) request to
the remote session LU partner. The remote LU
will then send an UNBIND request to terminate
the session.
poweroff(4) - terminate the LU-LU session by sending
either an SNA LUSTAT (LU Status) request on
the LU-LU session or an SNA NOTIFY request on
the SSCP-LU session indicating that the LU has

been powered off. Sending both is also
acceptable. The result should be that the
remote session LU partner will send an UNBIND
to terminate the session.

The default behavior indicated by the value of this
object may be overridden for an LU instance. The
override is performed by setting the snaLuAdminTerm
object instance in the snaLuAdminTable to the desired
value.

A write operation to this object may immediately
change the operational value reflected
in snaNodeOperLuTermDefault depending
on the Agent implementation."
::= { snaNodeAdminEntry 8 }

snaNodeAdminMaxLu OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The maximum number of LUs that may be
activated for this Node. For PU2.1, this object

DESCRIPTION
"The value identifies the remote host associated
with this Node.
Since SSCP Id's may not be unique
across hosts, the host description
is required to uniquely identify the SSCP.
This object is only applicable to PU2.0 type
Nodes. If the remote host is unknown, then the
value is the null string.

A write operation to this object may immediately

change the operational value reflected
in snaNodeOperHostDescription depending
on the Agent implementation."

DESCRIPTION
"The value indicates the desired method to be used
by the Agent to stop a Node (i.e., change the Node's
operational state to inactive(1) ).

The values have the following meaning:

other (1) - used for proprietary
methods not listed in this enumeration.
normal(2) - deactivate only when there is no more
activity on this Node (i.e., all data flows
have been completed and all sessions
have been terminated).
immed(3) - deactivate immediately regardless of
current activities on this Node. Wait for
deactivation responses (from remote Node)
before changing the Node state to inactive.

snaNodeAdminState OBJECT-TYPE
SYNTAX INTEGER {
inactive (1),
active (2)
}
MAX-ACCESS read-create

STATUS current
DESCRIPTION
"The value indicates the desired operational
state of the SNA Node. This object is used
by the Management Station to
activate or deactivate the Node.

If the current value in snaNodeOperState is
'active (2)', then setting this object to
'inactive (1)' will initiate the Node shutdown
process using the method indicated
by snaNodeOperStopMethod.

If the current value in snaNodeOperState is
'inactive (1)', then setting this object to
'active (2)' will initiate the
Node's activation.

A Management Station can always set this object to
'active (2)' irrespective of the value in the
snaOperEnablingMethod."
::= { snaNodeAdminEntry 12 }

snaNodeAdminRowStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object is used by a Management Station to
create or delete the row entry in the
snaNodeAdminTable following
the RowStatus textual convention.

Upon successful creation of
the row, an Agent automatically creates a
corresponding entry in the snaNodeOperTable with
snaNodeOperState equal to 'inactive (1)'.

Row deletion can be Management Station or Agent
initiated:
(a) The Management Station can set the value to
'destroy (6)' only when the value of
snaNodeOperState of this Node instance is
'inactive (1)'. The Agent will then delete the rows
corresponding to this Node instance from the
snaNodeAdminTable and the snaNodeOperTable.
(b) The Agent detects that a row is in the
'notReady (3)' state for greater than a

default period of 5 minutes.
(c) All rows with the snaNodeAdminRowStatus object's
value of 'notReady (3)' will be removed upon the
next initialization of the SNA services."

DESCRIPTION
"The value indicates the timestamp
(e.g., the Agent's sysUpTime value) of the last
change made to any object in the snaNodeAdminTable,
including row deletions/additions (e.g., changes to
snaNodeAdminRowStatus values).

This object can be used to reduce frequent
retrievals of the snaNodeAdminTable by a Management
Station. It is expected that a Management Station
will periodically poll this object and compare its
current value with the previous one. A difference
indicates that some Node configuration information
has been changed. Only then will the Management
Station retrieve the entire table."

"The value identifies the default method used to
deactivate LUs for this Node.

For LU6.2s, 'unbind(1)' is the only valid value.

unbind(1) - terminate the LU-LU session by sending
an SNA UNBIND request.
termself(2) - terminate the LU-LU session by sending
an SNA TERM-SELF (Terminate Self) request on
the SSCP-LU session. The SSCP will inform the
remote session LU partner to send an UNBIND
request to terminate the session.
rshutd(3) - terminate the LU-LU session by sending
an SNA RSHUTD (Request ShutDown) request to
the remote session LU partner. The remote LU
will then send an UNBIND request to terminate
the session.
poweroff(4) - terminate the LU-LU session by sending
either an SNA LUSTAT (LU Status) request on
the LU-LU session or an SNA NOTIFY request on
the SSCP-LU session indicating that the LU has
been powered off. Sending both is also
acceptable. The result should be that the
remote session LU partner will send an UNBIND

applies.

unbind(1) - terminate the LU-LU session by sending
an SNA UNBIND request.
termself(2) - terminate the LU-LU session by sending
an SNA TERM-SELF (Terminate Self) request on
the SSCP-LU session. The SSCP will inform the
remote session LU partner to send an UNBIND
request to terminate the session.
rshutd(3) - terminate the LU-LU session by sending
an SNA RSHUTD (Request ShutDown) request to
the remote session LU partner. The remote LU
will then send an UNBIND request to terminate
the session.
poweroff(4) - terminate the LU-LU session by sending
either an SNA LUSTAT (LU Status) request on
the LU-LU session or an SNA NOTIFY request on
the SSCP-LU session indicating that the LU has
been powered off. Sending both is also
acceptable. The result should be that the
