<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>.  Introduction</span>

   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 APPN (Advanced Peer-to-Peer Networking)
   capabilities.  This memo identifies managed objects for the APPN
   protocol.

<span class="h2"><a class="selflink" id="section-2" href="#section-2">2</a>.  The SNMPv2 Network Management Framework</span>

   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 [<a href="#ref-1" title="&quot;Structure of Management Information for version 2 of the Simple Network Management Protocol (SNMPv2)&quot;">1</a>, <a href="#ref-2" title="&quot;Textual Conventions for Version 2 of the Simple Network Management Protocol (SNMPv2)&quot;">2</a>, <a href="#ref-3" title="&quot;Conformance Statements for Version 2 of the Simple Network Management Protocol (SNMPv2)&quot;">3</a>], 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.

<span class="h2"><a class="selflink" id="section-3" href="#section-3">3</a>.  Overview</span>

   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 [<a href="#ref-7" title="&quot;Definition of Managed Objects for APPC&quot;">7</a>] and the
   SNA NAU MIB [<a href="#ref-8" title="&quot;Definition of Managed Objects for SNA NAUs using SMIv2&quot;">8</a>] for management of these sessions.  See also the DLUR
   MIB[9], and the HPR MIB[10] 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.  End nodes (ENs)
   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 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[11], the SNADLC LLC
   MIB[12], and the DLSw MIB[13].  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.  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 from
   NNs to ENs are kept in a local topology database.  Local topology
   information is shared with other NNs only during the session
   establishment process, to give the NN responsible for route
   calculation the necessary information for end-to- end route
   calculation.

   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 [<a href="#ref-4" title="Systems Network Architecture Technical Overview">4</a>],
   [<a href="#ref-5" title="Systems Network Architecture APPN Architecture Reference">5</a>], [<a href="#ref-6" title="Systems Network Architecture Formats">6</a>], and [<a href="#ref-14" title="Systems Network Architecture Management Services Formats">14</a>].

   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.

   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.

<span class="h3"><a class="selflink" id="section-3.1" href="#section-3.1">3.1</a>.  APPN MIB Structure</span>

   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.

<span class="h4"><a class="selflink" id="section-3.1.1" href="#section-3.1.1">3.1.1</a>.  appnNode group</span>

   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,
   including its network node server.

   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.

      STATUS current
      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
          ASCII-encoded hexadecimal digits, using the characters '0' -

-- This group is used to represent the entire APPN network-node topology
-- including network nodes, virtual routing nodes and all TGs associated
-- with these nodes.
--
-- 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 CP fully qualified 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:

-- 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.

<span class="h2"><a class="selflink" id="section-7" href="#section-7">7</a>.  Security Considerations</span>

   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 APPN 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.

   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.
