particular, it defines objects for receiving notifications from network
devices with APPN (Advanced Peer-to-Peer Network) and DLUR (Dependent LU
Requester) capabilities.  This memo identifies notifications for the
APPN and DLUR architecture.

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

1.  Introduction

This document is a product of the SNA NAU Services MIB Working Group.
It defines a MIB module for notifications for devices with Advanced
Peer-to-Peer Networking (APPN) and Dependent LU Requester (DLUR)
capabilities.

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 [13].


2.  The SNMP Network Management Framework

The SNMP Network Management Framework presently consists of six major
components.  They are:

o    the overall architecture, described in RFC 2271 [7].

o    the SMI, described in RFC 1902 [3], - the mechanisms used for
     describing and naming objects for the purpose of management.

o    the MIB-II, STD 17, RFC 1213 [2], - the core set of managed objects
     for the Internet suite of protocols.

o    the protocol, RFC 1157 [1] and/or RFC 1905 [6] and/or RFC 2272 [8]
     -- the protocol for accessing managed information.

o    the user-based security model defined in RFC 2274 [10].

o    the view-based access control model defined in RFC 2275 [11].

Textual conventions are defined in RFC 1903 [4], and conformance
statements are defined in RFC 1904 [5].  Common applications are defined
in RFC 2273 [9].

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

Internet Draft            SNANAU APPN TRAP MIB                  May 1998


This memo specifies a MIB module that is compliant to the SMIv2.  A MIB
conforming to the SMIv1 can be produced through the appropriate
translation.


3.  Overview

This document identifies the set of objects for reporting the status of
devices with APPN and DLUR capabilities via notifications.  See the
SNANAU APPN MIB [14] and SNANAU DLUR MIB [15] for the objects for
monitoring the configuration and active characteristics of the devices
with APPN and DLUR capabilities.

The SNANAU APPN MIB allows a management station to collect the network
topology of an APPN network (the network nodes (NNs) in the network and
all of transmission groups (TGs) between the network nodes) from an APPN
device.  It also allows the management station to collect the local
topology (TGs to end stations, and locally defined ports and link
stations) from an APPN device.  While the SNANAU APPN MIB has an
efficient way to poll the APPN device for updates to the network
topology, using flow reduction sequence numbers (FRSNs) as a table
index; it does not have a mechanism to poll the local topology tables
(appnLocalTgTable, appnPortTable, and appnLsTable) for status changes.

This MIB provides a mechanism for an APPN device to send notifications
to inform the management station of status changes to rows of these
tables. Status changes include operational state changes, and for TGs
also include control-point to control-point (CP-CP) session state
changes.  A notification is defined for each type of status change for
each table.

The port and link operational state objects have intermediate states.
Notifications are only sent for transition to active or inactive state.

Notifications are only sent for row creation if the state is active or
operational.  This is done to avoid sending a notification as the row is
created with an inactive initial state, followed by another notification
as the resource is activated.

Notifications are only sent for row deletion if the last state was
active or operational.  In most cases, a resource must be deactivated
before it can be deleted, and the deactivation will cause a notification
to be sent.  There is no need for a second notification to be sent for
the row deletion, except for the case where the deletion occurred
without deactivation.  In this case, the state of the object in the
notification will indicate an inactve state, since a deleted resource

Internet Draft            SNANAU APPN TRAP MIB                  May 1998


can no longer be active.

The purpose of the appnLocalTgCpCpStateChangeTrap notification is to
identify the loss or recovery of CP-CP sessions on a TG while the TG
remains operational.  Thus this notification is only sent if there is a
change to an appnLocalTgCpCpSession object, but not a change to the
appnLocalTgOperational object.  This notification is never sent for the
creation or deletion of a row in the appnLocalTgTable.

Each notification always contains an object which is a count of the
number of times the status of a row in table has changed since the APPN
node was last reinitialized.  This enables a management station to
detect that it has missed a notification, if it does not get the
notifications in numerical sequence.  If the notifications are not in
sequence, the management station should retrieve the entire table to get
the correct status for all rows.

Similarly, the SNANAU DLUR MIB provides a mechanism for retrieving the
configuration and status of dependent LU server (DLUS) sessions on a
device with DLUR capabilities.  This MIB defines a notification for a
DLUR-DLUS session state change of a row in the dlurDlusTable, in the
manner described above.  A notification is only sent for a session state
transition to active or inactive.  As with the above notifications, it
is only sent on row creation if the initial state is active; and on row
deletion is the last state was active, in which case the notification
indicates that the state is now inactive.

The SNANAU APPN MIB also provides a mechanism for a management station
to collect traffic statistics on intermediate sessions, primarily for
accounting purposes.  However, when the session is terminated, all
statistics from the last poll until the session termination time are
lost, since the row for that session is deleted from the appnIsInTable.
This MIB defines a notification so that the session's final statistics
can be sent to a management station.

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


o    A notification for an APPN local TG operational state change.

o    A notification for an APPN local TG CP-CP session state change.

o    A notification for an APPN port operational state change.

o    A notification for an APPN link station operational state change.

o    A notification for a DLUR-DLUS session state change.

o    A notification for reporting final APPN intermediate session
     statistics.


This MIB module does not support:


o    Objects to query the configuration or status of APPN nodes on
     demand.

o    Notifications for changes to local topology tables not related to
     status.

3.1.  APPN TRAP MIB Structure

The APPN TRAP MIB module contains a group of notifications, and a group
of supporting objects.

The group of notifications consists of the following notifications:

1) appnIsrAccountingDataTrap

This notification is generated by an APPN device when an intermediate
session is terminating, to report the final accounting statistics of the
session.

2) appnLocalTgOperStateChangeTrap

This notification identifies a change to the appnLocalTgOperational
object in a row of the SNANAU APPN MIB appnLocalTgTable.

3) appnLocalTgCpCpStateChangeTrap

This notification identifies a change to the appnLocalTgCpCpSession
object in a row of the SNANAU APPN MIB appnLocalTgTable.

4) appnPortOperStateChangeTrap

This notification identifies a change to the appnPortOperState object in
a row of the SNANAU APPN MIB appnPortTable.

5) appnLsOperStateChangeTrap

This notification identifies a change to the appnLsOperState object in a

Internet Draft            SNANAU APPN TRAP MIB                  May 1998


row of the SNANAU APPN MIB appnLsTable.

6) dlurDlusStateChangeTrap

This notification identifies a change to the dlurDlusSessnStatus object
in a row of the SNANAU DLUR MIB dlurDlusTable.


The group of supporting objects contains the appnTrapControl object,
which controls whether the APPN device generates each type of
notification.  Note that generation of the appnIsrAccountingDataTrap is
not controlled by this object; instead it is controlled by the
appnIsInGlobalCtrAdminStatus object in the SNANAU APPN MIB.

Although APPN notification generation could be controlled solely by
entries in the snmpNotificationMIB, RFC 2273 [9], the appnTrapControl
object exists in this MIB so that implementations are not required to
implement SNMPv3 to control generation of APPN notifications.  If
appnTrapControl enables APPN notifications, snmpNotificationMIB entries
could disable them.

Also contained in this group are objects for the TG, port, link, and
DLUR-DLUS session notifications to indicate the number of times each of
the tables has had a status change of a row since the APPN node was last
reinitialized.

          "When it has been enabled, this notification is generated by an
          APPN node whenever an ISR session passing through the node is
          taken down, regardless of whether the session went down
          normally or abnormally.  Its purpose is to allow a management
          application (primarily an accounting application) that is
          monitoring the ISR counts to receive the final values of these
          counts, so that the application can properly account for the
          amounts the counts were incremented since the last time the
          application polled them.  The appnIsInSessUpTime object
          provides the total amount of time that the session was active.

          This notification is not a substitute for polling the ISR
          counts.  In particular, the count values reported in this
          notification cannot be assumed to be the complete totals for
          the life of the session, since they may have wrapped while the
          session was up.

5.  Security Considerations

Certain management information defined in this MIB may be considered
sensitive in some network environments.  Therefore, authentication of
received SNMP requests and controlled access to management information
SHOULD be employed in such environments.  An authentication protocol is
defined in [10].  A protocol for access control is defined in [11].

None of the read-only objects in the APPN TRAP MIB reports a password,
user data, or anything else that is particularly sensitive.  Some
enterprises view their network configuration itself, as well as
information about network usage and performance, as corporate assets;
such enterprises may wish to restrict SNMP access to most of the objects
in the MIB.

There is one read-write object in the APPN TRAP MIB, appnTrapControl.
This object controls the generation of the notifications defined in the
APPN TRAP MIB.
