Abstract

  This memo defines a Management Information Base (MIB) for configuring
  and managing TN3270E servers.  TN3270E, defined by RFC 2355 [19],
  refers to the enhancements made to the Telnet 3270 (TN3270) terminal
  emulation practices.  Refer to RFC 1041 [18], STD 8, RFC 854 [16],
  and STD 31, RFC 860 [17] for a sample of what is meant by TN3270
  practices.

  The MIB defined by this memo provides generic support for both host
  and gateway TN3270E server implementations.  A TN3270E server
  connects a Telnet client performing 3270 emulation to a target SNA
  host over both a client-side network (client to TN3270E server) and
  an SNA Network (TN3270E server to target SNA host).  The client-side
  network is typically TCP/IP, but it need not be.

  A host TN3270E server refers to an implementation where the TN3270E
  server is collocated with the Systems Network Architecture (SNA)
  System Services Control Point (SSCP) for the dependent Secondary
  Logical Units (SLUs) that the server makes available to its clients
  for connecting into a SNA network.  A gateway TN3270E server resides
  on an SNA node other than an SSCP, either an SNA type 2.0 node, a
  boundary-function-attached type 2.1 node, or an APPN node acting in
  the role of a Dependent LU Requester (DLUR).  Host and gateway
  TN3270E server implementations typically differ greatly as to their
  internal implementation and system definition (SYSDEF) methods.

  subsequent memos.  For example, one such extension enables collection
  of TN3270E response time data.

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


2.0  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.

  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.

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


3.0  Structure of the MIB

  The TN3270E-MIB is split into the following components:

  o   TN3270E Server Control
  o   TN3270E Server Resource Configuration
  o   Resource/Client Address Mappings

  There are three additional sections to address:

  o   Advisory Spin Lock Usage
  o   Row Persistence
  o   IANA Considerations

  The TN3270E-MIB is defined primarily for TN3270E servers.  This memo
  does not explicitly address use of the MIB by TN3270 servers that do
  not support the TN3270E protocol.  Even though a significant number
  of the objects in the MIB do apply in the TN3270-only case, the case
  was not addressed, since it is unlikely that a TN3270-only server
  would implement this MIB.

  The SYSAPPL-MIB, reference [24], contains the Utf8String textual
  convention (TC) that the TN3270E-MIB imports.  This TC, which is used
  for some MIB objects containing textual information, enables
  internationalization of text strings, whereas the DisplayString TC
  does not.  The SNMP-FRAMEWORK-MIB, reference [1], contains the
  SnmpAdminString TC that the TN3270E-MIB also imports.  Like the
  Utf8String TC, this TC also enables internationalization of text
  strings; in addition, it provides some guidelines on the length and
  content of the strings.

  It is important to note that implementation of the SYSAPPL-MIB is not
  actually a prerequisite for implementing the TN3270E-MIB.  On the
  other hand, implementation of the TN3270E-MIB does not preclude
  implementing the SYSAPPL-MIB as well.  When both MIBs are
  implemented, the primary index into most of the TN3270E-MIB tables,
  tn3270eSrvrConfIndex, SHOULD equal one of the SYSAPPL-MIB's
  sysApplElmtRunIndex values.  In this case the entry in the
  sysApplElmtRunTable provides additional information on a TN3270E
  server.

  The MIB defined by this memo supports use of both IPv4 and IPv6
  addressing.  Two textual conventions, IANATn3270eAddrType and
  Tn3270eAddress, are defined for this purpose.  IANATn3270eAddress is
  essentially equivalent to the TAddress TC, defined by RFC 1903.  The
  difference between the two is that IANATn3270eAddress allows a zero-
  length octet string, while TAddress doesn't.  It is important that
  IANATn3270eAddress allow for the absence of an address, because some



White & Moore               Standards Track                     [Page 4]

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


  objects with this syntax are used as table indexes, and have special
  meanings when they contain zero-length strings.

  The IANATn3270eAddrType textual convention is used rather than the
  TDomain TC (defined by RFC 1903) for identifying the contents of a
  tn3270eTAddress object.  TDomain uses an OID to characterize the
  contents of an associated TAddress object.  IANATn3270eAddrType was
  chosen over TDomain because, with a SYNTAX of Unsigned32 (enumeration
  type), it is much simpler to use as a component in an instance
  identifier.  It was placed in the IANA-administered module to allow
  for the addition of values to cover cases (such as proxy servers) not
  covered by the TN3270E-MIB itself.

3.1  TN3270E Server Control

  This group of objects provides for TN3270E server configuration and
  control.  It consists of three tables:

  o   tn3270eSrvrConfTable
  o   tn3270eSrvrPortTable
  o   tn3270eSrvrStatsTable

  The tn3270eSrvrConfTable is the primary table within the entire
  TN3270E-MIB.  As section 3.1.1 indicates, each TN3270E server is
  represented by an entry in this table, indexed by
  tn3270eSrvrConfIndex.  Most of the other tables defined by the
  TN3270E-MIB have tn3270eSrvrConfIndex as their primary index.
  Entries in these tables MUST NOT exist for a TN3270E server when it
  does not have a tn3270eSrvrConfigEntry.

3.1.1  tn3270eSrvrConfTable

  The tn3270eSrvrConfTable contains a set of objects primarily used for
  configuring and managing TN3270E servers.  As with most of the other
  tables in the TN3270E-MIB, this table is indexed by an unsigned
  integer, tn3270eSrvrConfIndex.  This primary index element enables
  support of multiple TN3270E servers by a single SNMP agent.  Within
  the set of MIB objects returned by one SNMP agent,
  tn3270eSrvrConfIndex values MUST be unique, and need not be
  contiguous.

  The tn3270eSrvrConfInactivityTimer object defines the inactivity
  period for user traffic on TN3270 and TN3270E sessions.








White & Moore               Standards Track                     [Page 5]

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


  The four objects:

  o   tn3270eSrvrConfConnectivityChk
  o   tn3270eSrvrConfTmNopInterval
  o   tn3270eSrvrConfTmNopInactTime
  o   tn3270eSrvrConfTmTimeout

  define the parameters for performing the "Telnet Timing Mark Option"
  as defined by RFC 860 [17].  The object
  tn3270eSrvrConfConnectivityChk allows a Management Station to select
  either a NOP command or a TIMING-MARK command.  Sending a NOP command
  results in less overhead then a TIMING-MARK command, since a client
  doesn't send a reply.

  The objects tn3270eSrvrConfAdminStatus and tn3270eSrvrConfOperStatus
  enable remote starting and stopping of a TN3270E server, and report
  the current state of the server.  The object
  tn3270eSrvrConfFunctionsSupported indicates which of the TN3270 and
  TN3270E options a server supports.  The object
  tn3270eSrvrConfSessionTermState defines as a TN3270E server-wide
  option what SHOULD occur when the SNA portion of a TN3270 or TN3270E
  session terminates with respect to the associated TCP connection.
  The object tn3270eSrvrConfSrvrType indicates whether the TN3270E
  server represented by a tn3270eSrvrConfEntry is a host or a gateway
  server.  The object tn3270eSrvrConfContact provides a scratch pad
  area for a TN3270E server administrator to store information for
  later retrieval.  The object tn3270eSrvrConfLastActTime reports the
  DateAndTime when the server was most recently activated.  The special
  value of all '00'Hs indicates that the server has never been active.

  The object tn3270eSrvrConfRowStatus provides the capability to
  perform row creation and deletion operations on this table.

3.1.2  tn3270eSrvrPortTable

  The tn3270eSrvrPortTable represents the local TCP ports associated
  with a TN3270E server.  This information is important because some
  TN3270E server implementations support usage of multiple local ports.
  A tn3270eSrvrPortEntry is indexed by:

  o   tn3270eSrvrConfIndex
  o   tn3270eSrvrConfPort
  o   tn3270eSrvrConfPortAddrType
  o   tn3270eSrvrConfPortAddress

  Certain TN3270E server implementations restrict a local TCP port to a
  particular local IP address, instead of allowing connections for any
  local IP address to occur via the port.  tn3270eSrvrConfPortAddrType



White & Moore               Standards Track                     [Page 6]

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


  and tn3270eSrvrConfPortAddress allow this restriction to be
  represented in the MIB.  A TN3270E server that doesn't restrict
  connections over a port to a local IP Address SHALL use the value
  unknown(0) for tn3270eSrvrConfPortAddrType, and a zero-length octet
  string for tn3270eSrvrConfPortAddress.

3.1.3  tn3270eSrvrStatsTable

  The tn3270eSrvrStatsTable defines a series of objects that provide
  general usage statistics for a TN3270E server.  An entry can
  represent the total activity for a server, or it can represent the
  activity occurring at the server on either a port or a port-and-
  local-address basis.

  An implementation of this table MUST use only one of the three levels
  of refinement that the indexing of this table supports for the
  entries associated with a single TN3270E server.

  The objects in this table reporting maximum, in-use, and spare LUs
  for terminals and printers presuppose an implementation where
  terminal resources and printer resources come from disjoint,
  dedicated pools.  An implementation where resources for the two types
  of LUs come from a single shared pool should return the following
  values:

  o   maximum:  maximum size of the shared pool
  o   in-use:   number currently in use as this type of LU
  o   spare:    maximum - (terminal in-use + printer in-use)

3.2  TN3270E Server Resource Configuration

  The following three tables provide for configuration of resources at
  a TN3270E server:

  o   tn3270eClientGroupTable
  o   tn3270eResPoolTable
  o   tn3270eClientResMapTable

  tn3270eClientGroupTable and tn3270eResPoolTable enable
  implementations to define groupings of both client addresses and
  resource pools for mapping client addresses to resources.  The
  tn3270eClientResMapTable provides a mapping from a client group to a
  resource pool.

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


3.3  Resource Name / Client Address Mappings

  The TN3270E-MIB contains three tables for mapping resource names to
  client addresses, and client addresses to resource names:

  o   tn3270eSnaMapTable
  o   tn3270eResMapTable
  o   tn3270eTcpConnTable

3.3.1  tn3270eSnaMapTable

  The tn3270eSnaMapTable is a read-only table that maps a secondary
  LU's SNA network name to the name by which it is known locally at the
  TN3270E server.  For correlation with data from the SNA network, the
  name of the associated primary LU also appears in a
  tn3270eSnaMapEntry.  An entry in this table is created when the
  Activate LU (ACTLU) request carrying the SNA network name of the SLU
  is received from the SSCP.  The entry is deleted when the SLU is
  deactivated.

  A TN3270E server provides a client with access to an SNA application
  by associating a TCP connection from the client with an SNA secondary
  LU (SLU) at the server.  This SLU in turn has an SNA session with a
  primary LU (PLU) running on an SNA host.  This PLU represents the
  application with which the client is communicating.  The TN3270E-MIB
  includes two tables for mapping back and forth among the SNA name
  identifying the PLU, the SNA name identifying the SLU, and the TCP
  connection with the client.

  In order to understand how these name mappings work, it is necessary
  to understand a subtlety involving the names of the SLUs at the
  TN3270E server:  these names are often different from the names by
  which the SLUs are known in the rest of the SNA network.  In the
  TN3270E-MIB, these two types of SLU names are termed "local names"
  and "SSCP-supplied names"; the latter term indicates that the name by
  which the SLU is known in the SNA network comes to the TN3270E server
  from the SNA System Services Control Point.

  SSCPs don't always send SLU names down to secondary LUs; in some
  cases this capability must be turned on.  In the case of SLUs served
  by a Dependent LU Requester (DLUR), an SSCP always sends SLU names to
  the DLUR.  It is necessary, however, to enable the DLUR's PU/LU
  Network Name Forwarding function, so that it forwards the SLU names
  it receives from the SSCP down to the PUs that it serves.







White & Moore               Standards Track                     [Page 8]

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


  For SLUs associated with an SNA type 2.0 node (or with a boundary-
  function-attached type 2.1 node) not served by a DLUR, inclusion of
  SLU names on ACTLU must be enabled explicitly at the SSCP via local
  configuration.

3.3.2  tn3270eResMapTable

  The tn3270eResMapTable is a read-only table that maps a resource name
  to a client's address.  An entry in this table is created when a TCP
  connection is received by a TN3270E server and mapped to a resource.
  The entry is deleted when the resource-to-address association is no
  longer valid.

3.3.3  tn3270eTcpConnTable

  The TCP Connection Table is currently defined by RFC 2012 (Refer to
  reference [20], TCP-MIB Definitions).  It contains the following
  objects:

  o   tcpConnState (INTEGER)
  o   tcpConnLocalAddress (IpAddress)
  o   tcpConnLocalPort (INTEGER)
  o   tcpConnRemAddress (IpAddress)
  o   tcpConnRemPort (INTEGER)

  It is indexed by: tcpConnLocalAddress, tcpConnLocalPort,
  tcpConnRemAddress, and tcpConnRemPort.

  The tn3270eTcpConnTable contains objects for keeping a list of the
  current set of TN3270 and TN3270E sessions at a TN3270E server.  The
  relationship between the tcpConnTable and the Tn3270eTcpConnTable is
  not one-to-one, since the tn3270eTcpConnTable contains information
  pertaining only to TN3270(E) sessions.

  The tn3270eTcpConnTable has a different indexing structure from that
  of the tcpConnTable.  Instead of using IpAddress objects,
  Tn3270eAddress and IANATn3270eAddrType object pairs are used to
  specify client addresses (both local and remote).  This enables
  support of IPv6 addresses.  In addition, the remote address pair
  precedes the local address pair in the index clause, in order to
  enable a GET-NEXT operation using only the remote address pair.

3.4  Advisory Spin Lock Usage

  Within the TN3270E-MIB, tn3270eConfSpinLock is defined as an advisory
  lock that allows cooperating TN3270E-MIB applications to coordinate
  their use of the tn3270eSrvrConfTable, the tn3270eSrvrPortTable, the
  tn3270eClientGroupTable, the tn3270eResPoolTable, and the



White & Moore               Standards Track                     [Page 9]

RFC 2561                TN3270E Using SMIv2 MIB               April 1999


  tn3270eClientResMapTable.  When creating a new entry or altering an
  existing entry in any of these tables, an application SHOULD make use
  of tn3270eConfSpinLock to serialize application changes or additions.
  Since this is an advisory lock, its use by management applications
  SHALL NOT be enforced by agents.  Agents MUST, however, implement the
  tn3270eConfSpinLock object.

3.5  Row Persistence

  The following tables enable remote creation of their entries by
  including RowStatus objects:

  o   tn3270eSrvrConfTable
  o   tn3270eSrvrPortTable
  o   tn3270eClientGroupTable
  o   tn3270eResPoolTable
  o   tn3270eClientResMapTable

  An implementation SHOULD NOT retain SNMP-created entries in these
  tables across reIPLs (Initial Program Loads) of the corresponding
  TN3270E server, since management applications need to see consistent
  behavior with respect to the persistence of the table entries that
  they create.

  It is expected that local, implementation-dependent configuration
  information will be used to define the initial and persistent
  configurations for TN3270E server usage.  Thus it is not necessary to
  enable persistence of table entries by adding StorageType (refer to
  RFC 1903 [6]) objects to these tables.

3.6  IANA Considerations

  The tn3270eSrvrFunctionsSupported, tn3270eTcpConnFunctions,
  tn3270eTcpConnClientIdFormat, and tn3270eTcpConnLogInfo objects, as
  well as a number of objects identifying various address types,
  resource types, and device types, use textual conventions imported
  from the IANATn3270eTC-MIB.  The purpose of defining these textual
  conventions in a separate MIB module is to allow additional values to
  be defined without having to issue a new version of this document.
  The Internet Assigned Numbers Authority (IANA) is responsible for the
  assignment of all Internet numbers, including various SNMP-related
  numbers; it will administer the values associated with these textual
  conventions.

  The rules for additions or changes to the IANATn3270eTC-MIB are
  outlined in the DESCRIPTION clause associated with its MODULE-
  IDENTITY statement.

 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."

         of trace elements, with the trace elements in the
         string ordered from earliest to latest.

           where:

                    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.

5.0  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].

  Several objects in this MIB allow write access or provide for row
  creation.  Allowing this support in a non-secure environment can have
  a negative effect on network operations.  It is RECOMMENDED that
  implementers seriously consider whether set operations or row
  creation should be allowed without providing, at a minimum,
  authentication of request origin.  It is RECOMMENDED that without
  such support, the following objects be implemented as read-only:

  For all tables in the MIB except the tn3270eTcpConnTable, the first
  index identifies an individual TN3270E server.  This makes it easy to
  implement an access control policy under which different principals
  have access to objects related to different servers.  Implementation
  of such a policy is not possible for the entries in the
  tn3270eTcpConTable.
