Abstract
The purpose of this memo is to define a
Management Information Base
(MIB) for configuring and managing TN3270E Servers.
The MIB defined by this memo is intended to provide generic
support for both Host and Gateway TN3270E Server implementations.
It is the intent that the MIB defined herein be extended
by subsequent memos to provide non-generic configuration support
and to enable TN3270E Response Time Monitoring.
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 configuration and management of TN3270E
Servers.
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.
Expires December 1997 [Page 2]
White TN3270E Management Information Base (TN3270E-MIB)26 June 1997
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 TN3270E-MIB is split into the following components:
o TN3270E Server Control
o TN3270E Server Resource Configuration
o TCP Connection Table Additions
The TN3270E-MIB is defined for support primarily by TN3270E Servers.
Use of this MIB by TN3270 Servers that do not support the TN3270E
protocol is not explicitly addressed by this memo. A significant
portion of the objects do apply in the TN3270 only case. Addressing
the TN3270 only case was not done since it is unlikely that this MIB
would be implemented by TN3270 only servers.
3.1. TN3270E Server Control
This group of objects provides for TN3270 and TN3270E configuration
and consists of:
o tn3270eSrvrConfTable
o tn3270eSrvrPortTable
o tn3270eSrvrStatsTable
3.1.1. tn3270eSrvrConfTable
The tn3270eSrvrConfTable contains a set of objects primarily for
Expires December 1997 [Page 3]
White TN3270E Management Information Base (TN3270E-MIB)26 June 1997
configuring and managing a TN3270E Server. This table, as well most of
the tables in the TN3270E-MIB, are structured to be indexed by the
local IP Address (tn3270eSrvrConfIpAddr) and a unsigned integer
(tn3270eSrvrConfIndex). The primary index, tn3270eSrvrConfIpAddr, was
added to the tables in order for the tables to be used at both a
TN3270E Server host implementation as well as by a management
application that supports multiple TN3270E capable hosts. The second
index element, tn3270eSrvrConfigIndex, was added in order to support
multiple TN3270E Servers on the same host.
tn3270eSrvrConfInactivityTimer defines the inactivity period for
TN3270 and TN3270E Sessions. tn3270eSrvrConfSessionTermState defines
how a session should be terminated. The three objects:
o tn3270eSrvrConfActivityCheck
o tn3270eSrvrConfActivityTimeout
o tn3270eSrvrConfActivityInterval
defines the parameters for performing the "Telnet Timing Mark Option"
as defined by RFC 860 [3]. The object tn3270eSrvrConfActivityOption
was defined to enable sending of a NOP command as oppose to a TIMEMARK
command. Sending a NOP command results in less overhead then a
TIMEMARK command since a client doesn't send a reply.
The objects tn3270eSrvrConfAdminStatus and tn3270eSrvrConfOperStatus
exists in order to enable remote starting and stopping of a TN3270E
Server. tn3270eSrvrConfProtoSupported indicates which of the TN3270
and TN3270E options that a server supports. The object
tn3270eSrvrConfSrvrType indicates the implementation type of TN3270E
Server that the tn3270eSrvrConfEntry represents. The object
tn3270eSrvrConfRowStatus provides the capability to perform remote
creation and deletion operations on this table.
3.1.2. tn3270eSrvrPortTable
The tn3270eSrvrPortTable exists in order to assign and retrieve the
local ports associated with a TN3270E Server. Some implementations
support multiple local port usage.
3.1.3. tn3270eSrvrStatsTable
The tn3270eSrvrStatsTable defines a series of objects used to provide
general statistics on the use of a TN3270E Server.
Expires December 1997 [Page 4]
White TN3270E Management Information Base (TN3270E-MIB)26 June 1997
3.2. TN3270E Server Resource Configuration
The TN3270E Server Resource Configuration collection of objects consists
of four tables:
o tn3270eIpGroupTable
o tn3270eResPoolTable
o tn3270eResMapTable
o tn3270eIpMapTable
3.2.1. tn3270eIpGroupTable and tn3270eResPoolTable enable
implementations to define groupings of both IP Addresses and Resource
Pools for mapping IP Addresses to resources. The mapping of a IP Group
to a Resource Pool is enabled via tn3270eResPoolIpGroupName. Creating
an entry in the tn3270eResPoolTable results in creation of an entry or
entries in both the tn3270eResMapTable and tn3270eIpMapTable. Both the
tn3270eIpGroupTable and the tn3270eResPoolTable are optional since not
every TN3270E Server has the ability to define their IP to Resource
mappings in this manner. tn3270eResPoolClientPort exists to enable
implementations to restrict a collection of resources to a particular
local port. This object is optional since not every implementation
provides this type of support.
3.2.2. tn3270eResMapTable and tn3270eIpMapTable
The tables: tn3270eResMapTable and tn3270eIpMapTable provide mappings
of IP Address(es) to Resource(s) and Resource(s) to IP Address(es).
The index objects, tn3270eResMapClientPort and tn3270eIpMapClientPort,
as allowed to be zero when these tables are implemented by TN3270E
Servers that do provide local port to resource mapping.
3.3. TCP Connection Table Additions
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)
Expires December 1997 [Page 5]
White TN3270E Management Information Base (TN3270E-MIB)26 June 1997
and is indexed by: tcpConnLocalAddress, tcpConnLocalPort,
tcpConnRemAddress and tcpConnRemPort. The tn3270eTcpConnTableGroup
contains the objects defined by the tn3270eTcpConnTable for keeping a
list of the current set of TN3270 and TN3270E sessions at a TN3270E
Server. The tn3270eTcpConnTable has the same index elements as the
tcpConnTable but doesn't AUGMENT it since the relationship is not
one-to-one.

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 tn3270eSrvrConfInactivityTimer
o tn3270eSrvrConfActivityCheck
o tn3270eSrvrConfActivityTimeout
o tn3270eSrvrConfActivityInterval
o tn3270eSrvrConfAdminStatus
o tn3270eSrvrConfSessionTermState
o tn3270eIpGroupSubnetMask
o tn3270eResPoolIpGroupName
o tn3270eResPoolElementType
o tn3270eResPoolClientPort
o tn3270eResMapIpAddress
o tn3270eResMapSubnetMask
o tn3270eResMapElementType
o tn3270eIpMapResElementName
o tn3270eIpMapElementType
The following objects should either be implemented as read-only or not
implemented when security is an issue as previously discussed:
o tn3270eSrvrConfRowStatus
o tn3270eSrvrPortRowStatus
