  SnaResourceName ::= TEXTUAL-CONVENTION
      STATUS      current
      DESCRIPTION
          "The textual convention for defining an SNA resource
           name. A fully qualified SNA resource name, consisting
           of a 1 to 8 character network identifier (NetId), a
           period ('.'), and a 1 to 8 character resource name
           (ResName).

           The NetId and ResName 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.  Blanks are
           not allowed.

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

           Note: This Textual Convention is not subject to
           internationalization, and does not use the character
           encodings used by the Utf8String Textual Convention."

  Tn3270eTraceData ::= TEXTUAL-CONVENTION
      STATUS      current
      DESCRIPTION
          "An octet string representing trace data from the
          Telnet half of a TN3270E session, from the SNA half,
          or from both.  The octet string contains a sequence
          of trace elements, with the trace elements in the
          string ordered from earliest to latest.

          Each trace element has the following form:

                  +---+---+----+----------------------+
                  !length !type!data                  !
                  +---+---+----+----------------------+





            where:

            length = two-octet length of the data portion of the
                     trace element, not including the length and
                     type octets

            type   = one-octet code point characterizing the data;
                     defined values are:

                     X'01' telnet PDU from the server to the client
                     X'02' telnet PDU from the client to the server
                     X'03' SNA data from the server to the SNA host
                     X'04' SNA data from the SNA host to the server

            data   = initial part of a PDU.

          It is implementation-dependent where the 'initial part of
          a PDU' starts.  For SNA data, however, the starting point
          SHOULD be the first byte of the TH.  For IP data the
          starting point SHOULD be the first byte of the IP header.

          It is left to implementations to determine how much of
          each PDU to return in a trace element.

          The zero-length string indicates that no trace
          data is available."

          When a tn3270eSrvrConfEntry is deleted (by setting

          of removing all the associated entries (i.e., those

          tn3270eSrvrPortTable, the tn3270eSrvrStatsTable, the

          tn3270eTcpConnTable that belong to a TN3270E server
          that has been deleted MUST also be removed.






          In other words, a tn3270eSrvrConfEntry must exist for

           retained, how many entries are retained, and how long
           they are retained is entirely implementation-dependent.

           The indexing for this table is designed to support the
           use of an SNMP GET-NEXT operation using only the remote
           address type, remote address, and remote port, as a way
           for a Management Station to retrieve the table entries

           "Support of these objects is REQUIRED when the

           frequently.  This group is optional for all other
           hosts supporting the TN3270E-MIB.

           The IF-MIB (RFC 2233) requires that the 64-bit
           versions of its counters be implemented when an
           interface can support rates of around 20 million
           bits per second or greater.  This implies a minimum
           wrap rate of just over 28 minutes.  It is recommended
           that this same guideline be used for determining
           whether an implementation implements these objects.

           This group contains two objects with the syntax
           Counter64.  An implementation that doesn't support
           these objects should return noSuchObject, since
           returning a zero is misleading."
