RFC 2456 APPN TRAPS MIB November 1998
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 Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2271 [1].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
second version, called SMIv2, is described in RFC 1902 [5], RFC
1903 [6] and RFC 1904 [7].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC 1157 [8]. A second version of the SNMP
message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC 1901 [9] and
RFC 1906 [10]. The third version of the message protocol is
called SNMPv3 and described in RFC 1906 [10], RFC 2272 [11] and
RFC 2274 [12].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [8]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[13].
o A set of fundamental applications described in RFC 2273 [14] and
the view-based access control mechanism described in RFC 2275
[15].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
Clouston & Moore Standards Track PAGE 2
RFC 2456 APPN TRAPS MIB November 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
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
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 [18] and SNANAU DLUR MIB [19] for the objects
for monitoring the configuration and active characteristics of the
devices with APPN and DLUR capabilities. Many objects contained in
the notifications of this MIB are imported from the APPN and DLUR
MIBs. Implementors of this MIB must also implement the APPN MIB.
Implementations that support the appnTrapMibDlurConfGroup and the
appnTrapMibDlurNotifGroup must also implement the DLUR MIB.
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.
Clouston & Moore Standards Track PAGE 3
RFC 2456 APPN TRAPS MIB November 1998
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 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. If
the notification is not delivered, the final session statistics are
lost. If this is a concern, polling of the appnIsInTable in the APPN
Clouston & Moore Standards Track PAGE 4
RFC 2456 APPN TRAPS MIB November 1998
MIB should be increased to more likely reduce the time between the
last poll and the session termination, thereby reducing the amount of
data lost.
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.
Clouston & Moore Standards Track PAGE 5
RFC 2456 APPN TRAPS MIB November 1998
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 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 RFC 2273 to control generation of APPN notifications. For
a notification to be generated and sent as a TRAP or INFORM, the
notification type must first be enabled by the appnTrapControl
object. It must also not be disabled by an snmpNotificationMIB
entry. The destination of notifications is not within the scope of
this MIB.
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.

DESCRIPTION
"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.
The session to which the objects in this notification apply is
identified by the fully qualified CP name and PCID that make up
the table index. An instance of this notification will contain
exactly one instance of each of its objects, and these objects
will all belong to the same conceptual row of the
appnIsInTable.
Generation of this notification is controlled by the same
object in the APPN MIB, appnIsInGlobeCtrAdminStatus, that
controls whether the count objects themselves are being
incremented."

"When it has been enabled, this notification makes it possible

and thus to reduce the frequency with which it polls
for these changes.
This notification is sent whenever there is a change to

creation if the row is created with a value of 'true' for
appnLocalTgOperational. This notification is only sent for
row deletion if the last value of appnLocalTgOperational was
'true'. In this case, the value of appnLocalTgOperational
in the notification shall be 'false', since the deletion of
a row indicates that the TG is no longer operational.
The notification is more than a simple 'poll me now' indication.
It carries both a count of local TG topology changes, and the
current operational state itself. The count of changes allows an
application to detect lost notifications, either when polling
or upon receiving a subsequent notification, at which point it
knows it must retrieve the entire appnLocalTgTable again.
This is the same count as used in the appnLocalCpCpStateChangeTrap.
A lost notification could indicate a local TG CP-CP session state
change or an operational state change.

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 [12]. A protocol for access
control is defined in [15].
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.
