2.  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].


This memo does not specify a standard for the Internet community.

3.  The SNMPv2 Network Management Framework

The Internet-standard Network Management Framework presently consists of
three major components.  They are:

o    RFC 1902 [2] which defines the SMI, the mechanisms used for
     describing and naming objects for the purpose of management.

o    STD 17, RFC 1213 [3] which defines MIB-II, the core set of managed
     objects for the Internet suite of protocols.

o    RFC 1157 [4] and/or RFC 1905 [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.


4.  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

Internet Draft                 SNANAU MIB                     March 1996


"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    Activation/Deactivation of Nodes via the AdminState object in the
     snaNodeTable

o    Deactivation of sessions via the OperState object in the
     snaLuActSessnTable

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 session BIND failure

     This MIB module does not support:


o    creation of objects,

o    activation or deactivation of LUs, nor

o    activation of sessions.


4.1.  SNANUAU MIB Structure

The SNANAU MIB module contains three groups of objects:




Expires September 06, 1996                                      [Page 3]


Internet Draft                 SNANAU MIB                     March 1996


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.

Many objects are organized into two types of tables: the Admin and Oper
tables.


The "Admin" table contains read-only objects which contain default or
expected configuration values. This MIB does not create or modify
configuration values.  The "Oper" table contains objects which provide
current operational values, such as state values or negotiated
parameters, for dynamic or configured objects.  Dynamic objects are
created by the Agent system using one of the templates provided in the
"Admin" table.  Configured objects usually have a one-to-one
relationship between "Admin" and "Oper" entries.  However, some "Admin"
values may have changed since the object became operational, such that
the "Oper" values may no longer be based on the "Admin" values.  The
"Admin" entry could even be deleted.  For example, some implementations
may allow a link station definition (snaNodeLinkAdminEntry) to be
deleted even while the link station is active (snaNodeLinkOperEntry
still exists).  Where appropriate, the "Oper" table may include initial
starting values for objects that can be reconfigured while operational.
How the "Admin" values are changed or deleted is outside the scope of
this MIB.


4.1.1.  snaNode group

This table contains objects which describe runtime and operational state
variables for a Node, and an object to change the state of the node.
This table is indexed by the node name.


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.

Link-specific configuration objects are contained in a separate MIB
module (e.g., the SNA DLC MIB module) corresponding to link type.

2) snaPu20Table

Each row contains statistics variables and operational variables about a
PU type 2.0.

3) 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 table indices are the node
name and the link name.

4) 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.  The table indices are
the node name and the link name.

5) 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.


4.1.2.  snaLu group

The snaLu group consists of the following tables:

1) snaLuAdminTable

Table containing LU configuration information.  The rows in this table

Internet Draft                 SNANAU MIB                     March 1996


cannot 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 name and LU name.

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 is indexed by node name and LU name.

3) snaLuActSessnTable

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 is started, an
entry in the session table is created by the Agent.  When a session has
ended, the entry for that session is removed from the session table by
the Agent.  Entries are indexed by node name, local LU name, and a
unique session index assigned by the agent.

4) snaLuHistSessTable

This table contains historical information about abnormally terminated
sessions.  The table is indexed by an integer which will eventually
wrap.

5)snaLuSessStats

This group has objects that indicate and control gathering of
statistics, as well as the snaLuSessnStatsTable, which is a table
containing dynamic statistics information relating to LU-LU sessions.

5) snaLuTraps

The snaLuActSessBindFailTrap indicates the failure of a BIND request.


4.1.3.  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.


4.1.4.  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.
