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.

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.

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:

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.

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.

         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

--
-- 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.
