1. Introduction

 This document is a product of the SNA NAU Services MIB Working Group.
 It defines a MIB module for managing devices with Advanced Peer-to-
 Peer Networking (APPN) 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 [17].

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 2455 APPN 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 a set of objects for monitoring the
 configuration and active characteristics of devices with APPN
 capabilities, and for controlling certain characteristics.  APPN is
 the aspect of Systems Network Architecture (SNA) that supports peer-
 to-peer networking.  These networks transport both independent and
 dependent LU session traffic.  See the SNANAU APPC MIB [21] and the
 SNA NAU MIB [22] for management of these sessions.  See also RFC
 2232, the DLUR MIB [23], and RFC 2238, the HPR MIB [24] for
 management of extensions to the APPN architecture.  In this document,
 we describe APPN managed objects.
 An APPN network comprises various types of nodes, and transmission
 groups (TGs) that connect the nodes. Network nodes (NNs) provide
 directory and routing functions for session establishment.  NNs may
 be session end points or intermediate nodes in a session.  A border
 node is a type of network node that connects networks together for
 session establishment without fully merging them.  A branch network
 node (BrNN) is a network node that is similar to a border node, but
 with only minimal functions to build a large APPN network within an
 enterprise.  Although a BrNN is defined to be a network node in the
 APPN architecture, it also has an end node (EN) appearance to
 upstream NNs in the network.  In this MIB module it is treated as a
 separate node type since it does not fit cleanly as an EN or NN, and
 this module explicity identifies those objects returned by a BrNN.
 For example, a BrNN does not implement the appnNnTopo objects since
 it is the only node in its network topology table; but it does
 implement the appnSessIntermediate objects since it does have
 intermediate session support.  It also implements two of the
 appnEnUniqueCaps objects that could be useful to a management
 application.  A BrNN identifies itself as 'endNode' in the
 appnNodeType object but further identifies itself as a BrNN in the
 appnNodeBrNn object.
 End nodes are session end points that receive directory and routing
 functions from network nodes, over control-point to control-point
 (CP-CP) sessions.  Low-entry networking (LEN) nodes are also session

Clouston & Moore Standards Track [Page 3] RFC 2455 APPN MIB November 1998

 end points, but do not support CP-CP sessions, and therefore need
 additional manual configuration definitions to establish sessions in
 an APPN network.  ENs and LEN nodes may have minimal directory and
 routing functions to establish control sessions (ENs) or to connect
 into the APPN network (LEN nodes).
 Virtual routing nodes (VRNs) are not really nodes, but rather common
 definitions among actual nodes in a shared transport facility such as
 a local area network (LAN) that allow these actual nodes to
 temporarily establish a logical link with one another without
 defining each other's link-level addressing information.
 Ports and link stations are the node's interface to the data link
 control (DLC), which provides the physical transport, or to another
 protocol such as Data Link Switching (DLSw), which provides transport
 over an IP network.  See the SNADLC SDLC MIB[25], the SNADLC LLC
 MIB[26], and the DLSw MIB[27].  A link station uses a port to make a
 connection to another node.  This connection establishes a TG between
 the two nodes.
 The directory and routing functions enable an NN to find where an LU
 is located in the network, and calculate the optimal route for the
 session based on the requested class of service (COS).  A network
 node saves the LU information in a directory database, which is built
 from LUs defined locally, LU registration from served end nodes, and
 LUs learned from network searches.
 Each NN maintains a local COS database that assigns a routing weight,
 or relative cost, to each resource for each class of service.  For
 example, the #INTER COS assigns a lower weight to TGs with a greater
 effective capacity, while the #BATCH COS favors TGs with a lower
 relative cost per byte.
 A node saves network topology information (on NNs, VRNs, and TGs
 between them) in a network topology database. A node that supports
 APPN function set 1120, branch awareness, also saves information on
 TGs to adjacent BrNNs.  The topology information includes state and
 routing characteristics.  Topology information is exchanged between
 NNs over CP-CP sessions such that the database is fully replicated at
 each NN.  Information on TGs to all node types are kept in a local
 topology database. Local topology information is shared with other
 nodes only during the session establishment process, to give the NN
 responsible for route calculation the necessary information for end-
 to-end route calculation.
 A management application can show a full representation of the APPN
 network from the network and local topology information.  To show the
 network topology, the application need only query the network

Clouston & Moore Standards Track [Page 4] RFC 2455 APPN MIB November 1998

 topology tables from a single NN. To show all of the BrNNs, the
 application must also directly query all destinations of TGs that
 indicate they are branch TGs (indicated by the appnNnTgFRBranchTg
 object) to see if they have any cascaded BrNNs. For any NNs that do
 not indicate branch awareness support (indicated by the
 appnNnNodeFRBranchAwareness object), the application must query each
 NN's appnLocalTgTable, and then the appnNodeBrNn object of each row's
 destination node to identify BrNNs.  To show all of the nodes in the
 network, including ENs and LEN nodes, the application must query
 every NN's appnLocalTgTable, and iteratively do the same for each
 BrNN it finds.
 SNA names such as LU names, CP names, COS names, and mode names can
 be padded with blanks (space characters) in SNA formats.  These
 blanks are nonsignificant.  For example, in a BIND Request Unit (RU)
 a COS name of "#INTER" with a length of 6 is identical to a COS name
 of "#INTER  " with a length of 8.  However, in this MIB,
 nonsignificant blanks are not included by the agent.   Using the COS
 name from the previous example, an agent would return a length of 6
 and the string "#INTER" with no blanks for appnCosName, regardless of
 how it appears in the BIND RU or in internal storage.  The lone
 exception is the all blank mode name, for which the agent returns a
 length of 8 and the string "        " (8 blank spaces).  The MIB
 variables that this applies to are identified by a textual convention
 syntax that also describes this behavior.
 When an SNA name is functioning as a table index, an agent treats
 trailing blanks as significant.  If a management station requests the
 objects from a row with index "#INTER  ", the agent does not match
 this to the row with index "#INTER".  Since an agent has no
 nonsignificant blanks in any of its table indices, the only reason
 for a Management Station to include them would be to start GetNext
 processing at a chosen point in a table.  For example, a GetNext
 request with index "M       " would start retrieval from a table at
 the first row with an 8-character index beginning with "M" or a
 letter after "M".
 The SNA/APPN terms and overall architecture are documented in [18],
 [19], [20], and [28].
 Highlights of the management functions supported by the APPN MIB
 module include the following:
 o    Activating and deactivating ports and link stations.
 o    Monitoring of configuration parameters related to the node,
      ports, link stations, virtual routing nodes, and classes of
      service.

Clouston & Moore Standards Track [Page 5] RFC 2455 APPN MIB November 1998

 o    Monitoring of operational parameters related to ports, link
      stations, virtual routing nodes, topology, directory, and
      intermediate sessions.
 o    Historical information about link station errors during
      connection establishment, or that caused the connection to
      terminate.
 o    Deactivating intermediate sessions.
 o    Traps for SNA Management Services (SNA/MS) Alert conditions.
 This MIB module does not support:
 o    Configuration of APPN nodes.
 o    Monitoring and control of endpoint sessions.
 o    Dependent LU Requester (DLUR) management.
 o    High-Performance Routing (HPR) management.

3.1. Relationship with RFC 2155

 This MIB obsoletes RFC 2155 [29] with changes due to additions to the
 APPN architecture and some implementation experience of RFC 2155.
 The changes from RFC 2155 are as follows:
 o    New objects for the multi-link TG architecture enhancement:
      appnLsMltgMember, appnNnTgFRMltgLinkType,
      appnLocalTgMltgLinkType, and appnLocalEnTgMltgLinkType.
 o    New objects, and explanations for values for existing objects,
      for the branch network node architecture enhancement:
      appnNodeBrNn, appnNnNodeFRBranchAwareness, appnNnTgFRBranchTg,
      and appnLocalTgBranchLinkType.
 o    New object, appnNodeLsCounterType, to indicate which type of ANR
      traffic is returned in the appnLsTable traffic counters.
 o    Deprecated appnNodeMibVersion object.
 o    Miscellaneous editorial changes.

Clouston & Moore Standards Track [Page 6] RFC 2455 APPN MIB November 1998

3.2. APPN MIB Structure

 The APPN MIB module contains the following groups of objects:
 o    appnNode - objects related to the APPN node for all node types.
 o    appnNn   - objects to represent the network nodes, virtual
      routing nodes, and TGs between these nodes that make up the APPN
      network topology database maintained in NNs.
 o    appnLocalTopology  - objects to represent nodes and TGs between
      nodes in the local topology database maintained in all nodes.
 o    appnDir  - objects related to LU location information from the
      node's directory database.
 o    appnCos  - objects related to classes of service information.
 o    appnSessIntermediate - objects related to intermediate sessions
      that pass through this node.
 These groups are described below in more detail.

3.2.1. appnNode group

 The appnNode group consists of the following tables and objects:
 1) appnGeneralInfoAndCaps
 This group of objects describes general information about the APPN
 node.  The type of information includes the node type and the time
 since this node was initialized.
 2) appnNnUniqueInfoAndCaps
 This group of objects describes information specific to network nodes
 such as node routing characteristics.
 3) appnEnUniqueInfoAndCaps
 This group of objects describes information specific to end nodes,
 with two objects that also apply to branch network nodes.  This group
 includes an object indicating the node's network node server.

Clouston & Moore Standards Track [Page 7] RFC 2455 APPN MIB November 1998

 4) appnPortInformation
 This includes the appnPortTable, which describes the configuration
 and current status of the ports used by APPN, including the port
 state and DLC type.
 5) appnLinkStationInformation
 This includes the appnNodeLsTable, which describes the configuration
 and current status of the link stations used by APPN, including the
 link state and port name; and the appnLsStatusTable, which provides
 information about errors this node encountered with connections to
 adjacent nodes, such as the sense data captured during connection
 failures.  It is a product option to decide how many
 appnLsStatusTable entries are kept.
 6) appnVrnInfo
 This includes the appnVrnTable, which describes the relationship
 between virtual routing nodes' TGs described in the appnLocalTgTable
 with ports in the appnPortTable.

3.2.2. appnNn group

 The appnNn group consists of the following objects and tables
 1) appnNnTopo
 These objects contain general information about the network topology
 database including the number of nodes present, and the number of
 topology database updates (TDU) wars the node has detected.
 2) appnNnTopology
 This includes tables representing the APPN network topology database.
 This includes the network nodes, virtual routing nodes, and TGs
 between these nodes, as well as the information about these resources
 carried in topology updates.  The tables are first indexed by the
 same flow reduction sequence number (FRSN) used in topology exchanges
 between NNs.  This allows a management station to retrieve only
 incremental updates, since the agent will update the FRSN of new or
 changed resources.

3.2.3. appnLocalTopology group

 The appnLocalTopology group consists of the following objects and
 tables:

Clouston & Moore Standards Track [Page 8] RFC 2455 APPN MIB November 1998

 1) appnLocalThisNode
  a) appnLocalGeneral
  Contains the local node and type.
  b) appnLocalNnSpecific
  These objects contain routing information about the local network
  node.
  c) appnLocalTg
  This table represents information about this node's local TGs.
 2) appnLocalEnTopology
 This table represents TG information for EN TGs learned by the NN via
 TG registration with the local node.

3.2.4. appnDir group

 The appnDir group consists of the following objects and tables:
 1) appnDirPerf
 These objects represent information related to information about the
 directory database and directory searches involving this node.
 2) appnDirTable
 This table represents the directory database, listing LUs known to
 this node, along with the owning node of the LU and the serving NN of
 the owning node.

3.2.5. appnCos group

 The appnCos group consists of the following tables:
 1) appnCosModeTable
 This table represents the mode to class of service mapping.
 2) appnCosNameTable
 This table represents the tranmission priority for each class of
 service.

Clouston & Moore Standards Track [Page 9] RFC 2455 APPN MIB November 1998

 3) appnCosNodeRowTable
 This table represents the node-row information for each class of
 service, including the weight of each node.
 3) appnCosTGRowTable
 This table represents the TG-row information for each class of
 service, including the weight of each TG.

3.2.6. appnSessIntermediate group

 The appnSessIntermediate group consists of the following objects and
 tables:
 1) appnIsInGlobal
 These objects allow control of the collection of intermediate session
 information such as Route Selection Control Vectors (RSCVs) and
 counters.
 2) appnIsInTable
 This table contains information on active intermediate sessions.
 3) appnIsRtpTable
 This table contains information on active intermediate sessions that
 are being transported on Rapid Transport Protocol (RTP) connections
 by High Performance Routing (HPR).

3.2.7. appnTraps

 One APPN trap is defined.  It is intended to correspond to SNA/MS
 Alerts, but is optional for a product to implement this trap.  The
 trap identifies the Alert ID number and, where possible, the affected
 resource.

    DESCRIPTION
        "An SNA Node Identification consists of two parts, which
        together comprise four bytes of hexadecimal data.  In SNA the
        Node Identification is transported in bytes 2-5 of the XID.
        The block number is the first three digits of the Node
        Identification.  These 3 hexadecimal digits identify the
        product.
        The ID number is the last 5 digits of the Node Identification.
        These 5 hexadecimal digits are administratively defined and
        combined with the 3-digit block number form the 8-digit Node
        Identification.  A unique value is required for connections to
        SNA subarea.  In some implementations, the value 'bbb00000'
        (where 'bbb' represents a 3-digit block number) is returned to
        mean that the ID number is not unique on this node.
        An SNA Node Identification is represented as eight

Clouston & Moore Standards Track [Page 54] RFC 2455 APPN MIB November 1998

– – Network nodes – The APPN topology database consists of information about every APPN – network node in this network node's topology subnetwork. This – information is learned over time as each network node exchanges – topology information with the network nodes adjacent to it. The – database consists of information about each node, and information – about all of the transmission groups used by these nodes. – – Virtual routing nodes – Information about virtual routing nodes (representing connection – networks) is treated in the same way as information about network – nodes, and is replicated at each network node. The FRSN, node name, – and node type are the only meaningful fields for a virtual routing – node. The other node objects return unspecified values. Each – node that has defined a TG with this virtual routing node as the – destination also defines a TG on this virtual routing node. There – is a TG record for each node that uses this virtual routing node. – – The APPN node table represents node information from the APPN topology – database, with the FRSN and APPN fully qualified CP name serving as – the index. The FRSN is the agent's relative time stamp of an update – to the network topology database. After collecting the entire database – once, a management application can issue GET NEXT commands starting – from the last rows it has retrieved from the appnNnTopologyFRTable and – from the appnNnTgTopologyFRTable. When the response to either of these – GET NEXT commands returns another row of its respective table, this – indicates a change to the agent's topology database. The management – application can then retrieve only the updates to the table, using – GET NEXT commands starting from the last retrieved node or TG entry. – – The format of the actual APPN topology database is as follows: – – Node table (entry for each node in network) – TG table (entry for each TG owned by node) – – Due to SNMP's ASN.1 limitations, we cannot represent the TG table – within the node table in this way. We define separate tables for – nodes and TGs, adding the node name to each TG entry to provide a – means of correlating the TG with its originating node.

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].
 The read-only objects appnNnTgFRSecurity, appnLocalTgSecurity,
 appnLocalEnTgSecurity, appnCosTgRowSecurityMin, and
 appnCosTgRowSecurityMax can be used to determine the potential path
 of secure data. While these objects cannot be changed by a management
 application using this MIB, these objects could be used to determine
 where a security exposure exists due to an improper configuration on
 the agent.
 None of the other read-only objects in the APPN MIB reports a
 password, user data, or anything else that is particularly sensitive.
 Some enterprises view their network configuration itself, as well as

Clouston & Moore Standards Track [Page 135] RFC 2455 APPN MIB November 1998

 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.
 Four of the read-write objects in the MIB can affect network
 operations; it is recommended that SNMP access to these objects be
 restricted.  The four objects are:
 o    appnNodeNnSafeStoreFreq:  Setting this object to 0, or to a very
      large value, effectively turns off safe storing of topology
      data.
 o    appnPortCommand, appnLsCommand:  These two objects allow an APPN
      port or link station to be activated, deactivated, or recycled
      via an SNMP operation.  The latter two operations may disrupt
      current users of the network.
 o    appnIsInSessState:  Setting this object to 'inactive' causes an
      active SNA session to be deactivated.
      Other read-write objects control the gathering of network
      management data; controlling access to these objects is less
      critical.
