Abstract

  The purpose of this memo is to define the Management Information Base
  (MIB) for configuring and monitoring TN3270 and TN3270E sessions.
  The monitoring portion of the MIB is limited to AUGMENTation of
  the TCP Connection Table (RFC 2012) with a set of objects collected
  from the TCP Layer. It is the intent of this MIB to
  fully adhere to all prerequisite MIBs unless explicitly stated.
  Deviations will be documented in corresponding conformance statements.
  The specification of this MIB will utilize the
  Structure of Management Information (SMI) for Version 2 of the
  Simple Network Management Protocol Version (refer to RFC1902,
  reference [1]).

1.  Introduction

  This document is a product of the TN3270E Working Group. Its purpose
  is to define a MIB module for extending the traditional MIBs supported
  by a TCP/IP implementation for configuring and monitoring of TN3270
  and TN3270E sessions.


2.  The SNMPv2 Network Management Framework

  The SNMP Network Management Framework presently consists of three
  major components.  They are:

  o the SMI, described in RFC 1902 [1], - the mechanisms used for
    describing and naming objects for the purpose of management.

  o the MIB-II, STD 17, RFC 1213 [5], - the core set of managed
    objects for the Internet suite of protocols.

  o the protocol, RFC 1157 [9] and/or RFC 1905 [7] - the protocol
    for accessing managed information.

  Textual conventions are defined in RFC 1903 [6], and conformance
  statements are defined in RFC 1904 [8].

  The Framework permits new objects to be defined for the purpose of
  experimentation and evaluation.

  This memo specifies a MIB module that is compliant to the SNMPv2 SMI.
  A semantically identical MIB conforming to the SNMPv1 SMI can be
  produced through the appropriate translation.

2.1.  Object Definitions

  Managed objects are accessed via a virtual information store, termed
  the Management Information Base or MIB.  Objects in the MIB are
  defined using the subset of Abstract Syntax Notation One (ASN.1)
  defined in the SMI.  In particular, each object object type is named
  by an OBJECT IDENTIFIER, an administratively assigned name.  The
  object type together with an object instance serves to uniquely
  identify a specific instantiation of the object.  For human
  convenience, we often use a textual string, termed the descriptor, to
  refer to the object type.



3.  Structure of the MIB

  The TN3270-MIB is split into the following components:

    o Base TN3270 MIB Definitions
    o MIB Definitions for AUGMENTing the TCP Connection Table



3.1.  Base TN3270 MIB Definitions

  The collection of MIB Objects defined by the tn3270BasicGroup.  This
  group of objects provides for TN3270 and TN3270E configuration.


3.2.  MIB Definitions for AUGMENTing the TCP Connection Table

  The TCP Connection Table is defined by RFC 2012 (Refer to reference
  10, TCP-MIB Definitions). Traditionally, the contents of the TCP
  Connection Table has been implementation dependent.  Its formal
  definition consists of the following objects:

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

  and is indexed by: tcpConnLocalAddress, tcpConnLocalPort,
  tcpConnRemAddress and tcpConnRemPort. The tn3270TcpConnTableGroup
  contains the objects defined by the tn3270TcpConnTable for AUGMENTing
  the tcpConnTable. The objects contained within the
  tn3270TcpConnTableGroup can be set by either a TN3270 or TN3270E
  Server or if TCP specific by the TCP Stack.

5.  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.  The method for this
  authentication is a function of the SNMP Administrative Framework, and
  has not been expanded by this MIB.

  Several objects in this MIB allow write access or provide for remote
  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 should be
  allowed without providing, at a minimum, authentication of request
  origin. It it recommended that without such support that the following
  objects be implemented as read-only:

      o tn3270Port
      o tn3270InactivityTimer
      o tn3270Timemark
      o tn3270ScanInterval
      o tn3270BinaryLineMode
      o tn3270DisableSga
      o tn3270AdminStatus
      o tn3270DefaultApplName
      o tn3270DefaultApplIpAddress

      o tn3270DefaultApplIpGroupName
      o tn3270DefaultApplIfIndex
      o tn3270TelnetAppl
      o tn3270LmApplName
      o tn3270LmApplIpAddress
      o tn3270LmApplIpGroupName
      o tn3270LmApplIfIndex

      o tn3270UsstcpIpAddress
      o tn3270UsstcpIpGroupName
      o tn3270UsstcpIfIndex
      o tn3270SessionTermState
      o tn3270Msg07Enabled
      o tn3270OldSolicitorEnabled
      o tn3270AllowApplDisconnect

      o tn3270PrtGroupRowStatus
      o tn3270LuMapIpAddr

      o tn3270PrtMapIpAddr
      o tn3270PrtMapIpGroupName
      o tn3270LogmodeName

  The following objects should either be implemented as read-only or not
  implemented when security is an issue as previously discussed:

      o tn3270AllowApplRowStatus
      o tn3270RestrictApplRowStatus
      o tn3270IpGroupRowStatus
      o tn3270LuMapRowStatus
      o tn3270PrtMapRowStatus
      o tn3270LogmodeRowStatus
