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:
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.
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.

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.
