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:

   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.

   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.

SnaNodeIdentification ::= TEXTUAL-CONVENTION
      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' -
          '9' and 'A' - 'F'."

RFC 2455                        APPN MIB                   November 1998


      STATUS current
      DESCRIPTION
          "A fully qualified SNA control point name, consisting of a 1 to
          8 character network identifier (NetId), a period ('.'), and a 1
          to 8 character control point name (CpName).

          The NetId and CpName are constructed from the uppercase letters
          'A' - 'Z' and the numerics '0' - '9', all encoded in ASCII,
          with the restriction that the first character of each must be
          a letter.  Trailing blanks are not allowed.

          Earlier versions of SNA permitted three additional characters
          in NetIds and CpNames:  '#', '@', and '$'.  While this use of
          these characters has been retired, a Management Station should
          still accept them for backward compatibility."

SnaClassOfServiceName ::= TEXTUAL-CONVENTION
      STATUS current
      DESCRIPTION
          "An SNA class-of-service (COS) name, ranging from 1 to 8
          ASCII characters.  COS names take one of two forms:

             -  a user-defined COS name is constructed from the uppercase
                letters 'A' - 'Z' and the numerics '0' - '9', with the
                restriction that the first character of the name must be
                a letter.
             -  an SNA-defined user-session COS name begins with the
                character '#', which is followed by up to seven
                additional characters from the set of uppercase letters
                and numerics.

          Trailing blanks are not allowed in either form of COS name.

          A zero-length string indicates that a COS name is not
          available."

SnaModeName ::= TEXTUAL-CONVENTION
      STATUS current
      DESCRIPTION
          "An SNA mode name, ranging from 1 to 8 ASCII characters.
          Mode names take one of two forms:

                additional characters from the set of uppercase letters
                and numerics.

          Trailing blanks are not allowed in either form of mode name,
          with the single exception of the all-blank mode name, where
          a string consisting of 8 blanks is returned.

          condition is available.
