   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).

3.1.7.  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'."

SnaControlPointName ::= TEXTUAL-CONVENTION
      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

      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:

             -  a user-defined mode 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 mode 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 mode name,
          with the single exception of the all-blank mode name, where
          a string consisting of 8 blanks is returned.

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

          condition is available.

          OCTET STRING containing 0 to 64 ASCII characters.
          A Management Station should use a value of this type only
          for display.  The 'real' DLC address, i.e., the sequence of
          bytes that flow in the DLC header, is often available in a
          DLC-specific MIB.
