- 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 monitoring and controlling
- network devices with DLUR (Dependent LU Requester) capabilities.
- This memo identifies managed objects for the DLUR protocol.

- 3. The SNMP Network Management Framework
-
- The SNMP Network Management Framework consists of several components.
- For the purpose of this specification, the applicable components of
- the Framework are the SMI and related documents [1, 2, 3], which
- define the mechanisms used for describing and naming objects for the
- purpose of management.
-
- The Framework permits new objects to be defined for the purpose of
- experimentation and evaluation.
-
- 4. Overview
-
- This document identifies objects for monitoring the configuration and
- active characteristics of devices with DLUR capabilities. Dependent
- LU requester/server (DLUR/S) is an extension to the Advanced Peer-
- to-Peer Networking (APPN) architecture that provides dependent LU
- services in APPN networks. See the SNANAU APPN MIB [4] for
- management of APPN networks.
-
- The base APPN architecture only provided for transport of data
- between independent logical units (LUs). However, customers have an
- enormous investment in applications based on dependent LU types.
- DLUR/S provides for support of dependent LU sessions in an APPN
- network.
-
- A dependent LU server (DLUS) is an APPN node that provides System
- Services Control Point (SSCP) services over an APPN network to remote
- secondary dependent LUs by using SSCP-PU (physical unit) and SSCP-LU
- sessions whose flows are encapsulated on LU 6.2 session flows between
- the DLUS node and the appropriate dependent LU requester (DLUR) node.
- The secondary dependent LUs may be local to the DLUR node, or in
- adjacent type 2.0 or 2.1 nodes.
-
- The LU 6.2 control sessions between a DLUS node and a DLUR node are
- referred to as a CPSVRMGR pipe. CPSVRMGR refers to the mode used for
- the sessions.
-
- In this document, we describe DLUR managed objects.
-
- The DLUR terms and overall architecture are described in [5].
-
- Highlights of the management functions supported by the DLUR MIB
- module include the following:
-
-
-
-
-
-
-
- Clouston & Moore Standards Track [Page 2]
-
- RFC 2232 Managed Objects for DLUR using SMIv2 November 1997
-
-
- o Identifying the node's DLUR capabilities
-
- o Displaying the physical units (PUs) this node is supporting
-
- o Identification of Dependent LU Servers
-
- o Displaying the state of control sessions to Dependent LU
- Servers.
-
- This MIB module does not support:
-
- o Management of dependent LU servers
-
- o Configuration of DLUR nodes.
-
- o Changing the state of control session to the DLUS
-
- o Displaying the dependent LUs this node is supporting
-
- o Traps. The APPN MIB contains a trap for Alert conditions that
- may affect DLUR resources. The value for the affectedObject
- object contained in the alertTrap is determined by the
- implementation. It may contain a VariablePointer from the DLUR
- MIB. The APPN/DLUR Alerts are defined in [6].
-
- 4.1. DLUR MIB Structure
-
- Although DLUR is an extension to APPN, the DLUR MIB relies very
- little upon the APPN MIB. The dlurNodeCpName object in this MIB has
- the same value as the appnNodeCpName object in the APPN MIB. If the
- dlurPuLsName object in the MIB has the same value as the appnLsName
- object in the APPN MIB, then the two objects are referring to the
- same link station.
-
- The DLUR MIB module contains the following collections of objects:
-
- o dlurNodeInfo--objects representing the capabilities and
- architecture options supported by the DLUR implementation, as
- well as default primary and backup DLUSs.
-
- o dlurPuInfo--objects describing the PUs that this APPN node is
- supporting with DLUR.
-
- o dlurDlusInfo--objects describing the control sessions with
- DLUSs.
-
- These are described below in more detail.

-
- RFC 2232 Managed Objects for DLUR using SMIv2 November 1997
-
-
- 4.1.1. dlurNodeInfo group
-
- The dlurNodeInfo group consists of the following objects and table:
-
- 1) dlurNodeCapabilities group
-
- These objects represent the capabilities and options of the DLUR
- implementation, such as the release level of the implementation
-
- 2) dlurDefaultDefBackupDlusTable
-
- This table identifies the list of defined backup DLUSs for all PUs
- served by this DLUR, if there is no specific DLUS backup list for the
- PU. The list is in descending order of preference as a backup DLUS.
-
- 4.1.2. dlurPuInfo group
-
- The dlurPuInfo group consists of the following tables:
-
- 1) dlurPuTable
-
- This table has an entry for each PU this node is supporting via DLUR,
- including the locally known name, the SSCP supplied name (if known),
- and the PU status.
-
- 2) dlurPuDefBackupDlusTable
-
- This table contains the backup DLUS list defined on a PU basis. The
- table has an entry for each specifically defined backup DLUS on each
- PU. The first index to the entry is the PU name, which organizes the
- table by PU name. The second index is a ranking which further sorts
- the table in descending order of preference as a backup DLUS for the
- PU.
-
- If a PU name is not found in this table, the
- dlurDefaultDefBackupDlusNameTable is used as a backup list for that
- PU.
-
- 4.1.3. dlurDlusInfo group
-
- This group consists of the following table:
-
- 1) dlurDlusTable
-
- This table contains information about the control sessions (CPSVRMGR
- pipes) with the DLUS, including the control point (CP) name of the
- DLUS and the status of the control session.

- DESCRIPTION
- "Status of the CPSVRMGR pipe between the DLUR and this DLUS.
- This is a combination of the separate states for the
- contention-winner and contention-loser sessions:
-
- reset(1) - none of the cases below
- pendingActive(2) - either contention-winner session or
- contention-loser session is pending active
- active(3) - contention-winner and contention-loser
- sessions are both active
- pendingInactive(4) - either contention-winner session or
- contention-loser session is pending
- inactive - this test is made AFTER the
- 'pendingActive' test.
-
- The following matrix provides a different representation of
- how the values of this object are related to the individual
- states of the contention-winner and contention-loser sessions:
-
- Conwinner
- | pA | pI | A | X = !(pA | pI | A)

- 8. Security Considerations
-
- In most cases, MIBs are not themselves security risks; if SNMP
- security is operating as intended, the use of a MIB to view
- information about a system, or to change some parameter at the
- system, is a tool, not a threat.
-
- None of the read-only objects in the DLUR 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 are no read-write objects in the DLUR MIB.
