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.
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.
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
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:
- appnIsrAccountingDataTrap
This notification is generated by an APPN device when an intermediate session is terminating, to report the final accounting statistics of the session.
- appnLocalTgOperStateChangeTrap
This notification identifies a change to the appnLocalTgOperational object in a row of the SNANAU APPN MIB appnLocalTgTable.
- appnLocalTgCpCpStateChangeTrap
This notification identifies a change to the appnLocalTgCpCpSession object in a row of the SNANAU APPN MIB appnLocalTgTable.
- appnPortOperStateChangeTrap
This notification identifies a change to the appnPortOperState object in a row of the SNANAU APPN MIB appnPortTable.
- appnLsOperStateChangeTrap
This notification identifies a change to the appnLsOperState object in a row of the SNANAU APPN MIB appnLsTable.
- 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.

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."

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.

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.
