Abstract

This memo defines a Management Information Base (MIB) for configuring
and managing TN3270E servers.  TN3270E, defined by RFC 1647 (reference
[14]), refers to the enhancements made to the Telnet 3270 (TN3270)
terminal emulation practices.  Refer to: RFC 1041, reference [4]; RFC
854, reference [2]; and RFC 860, reference [3] 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 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 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) requirements.

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 collection.  The specification of this MIB uses
the Structure of Management Information (SMI) for Version 2 of the
Simple Network Management Protocol Version (refer to RFC 1902, reference
[1]).

1.0  Introduction

This document is a product of the TN3270E Working Group.  Its purpose is
to define a MIB module for support by a TCP/IP implementation for
configuration and management of TN3270E servers.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",

2.0  The SNMPv2 Network Management Framework

The SNMPv2 Network Management Framework consists of seven major
components.  They are:

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

o   RFC 1903 [6] defines textual conventions for SNMPv2.

o   RFC 1904 [8] defines conformance statements for SNMPv2.

o   RFC 1905 [7] defines  transport mappings for SNMPv2.

o   RFC 1906 [5] defines the protocol operations used for network access
    to managed objects.

o   RFC 1907 [9] defines the Management Information Base for SNMPv2.

o   RFC 1908 [16] specifies coexistence between SNMP and SNMPv2.

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.


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 two additional sections to address:

o   Advisory Spin Lock Usage
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.



TN3270E Working Group      Expires July 1998                    [Page 3]

Internet Draft                TN3270E MIB                   January 1998

The SYSAPPL-MIB, reference [12], 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.

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 SNMP-FRAMEWORK-MIB, reference [15], contains the SnmpAdminString TC
that the TN3270E-MIB 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.

The MIB defined by this memo handles both IPv4 and IPv6 addressing.  Two
textual conventions, Tn3270eAddrType and Tn3270eTAddress, are defined
for this purpose.  Tn3270eTAddress is essentially equivalent to the
TAddress TC, defined by RFC 1903.  The difference between the two is
that Tn3270eTAddress allows a zero-length octet string, while TAddress
doesn't.  It is important that Tn3270eTAddress allow for the absence of
an address, because some objects with this syntax are used as table
indexes, and have special meanings when they contain zero-length
strings.

The Tn3270eAddrType 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.  Tn3270eAddrType 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.

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.



TN3270E Working Group      Expires July 1998                    [Page 4]

Internet Draft                TN3270E MIB                   January 1998

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; otherwise these values are
implementation-dependent.

An earlier version of this memo had used the local IP address associated
with a TN3270E server, along with tn3270eSrvrConfIndex, as the primary
indexes into most of its tables.  Use of a local IP address was thought
to enable use of these tables by management applications.  This approach
was dropped, since it introduced another level of complexity into MIB
table indexing for little actual benefit.

The tn3270eSrvrConfInactivityTimer object defines the inactivity period
for TN3270 and TN3270E sessions.  The tn3270eSrvrConfSessionTermState
object defines how a session SHOULD be terminated.  The three objects:

o   tn3270eSrvrConfActivityCheck
o   tn3270eSrvrConfActivityTimeout
o   tn3270eSrvrConfActivityInterval

define the parameters for performing the "Telnet Timing Mark Option" as
defined by RFC 860 [3].  The object tn3270eSrvrConfActivityCheck allows
a Management Station to select either a NOP command or 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
enable remote starting and stopping of a TN3270E server.
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
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 multiple local ports.  A
tn3270eSrvrPortEntry is indexed by:

o   tn3270eSrvrConfIndex
o   tn3270eSrvrConfPort

TN3270E Working Group      Expires July 1998                    [Page 5]

Internet Draft                TN3270E MIB                   January 1998

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 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 SHOULD 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.

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.

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

TN3270E Working Group      Expires July 1998                    [Page 6]

Internet Draft                TN3270E MIB                   January 1998

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 the secondary LUs; in some
cases this capability must be turned on.  In the case of SLUs served by
a Dependent LU Requester (DLUR), the capability is always turned on.
For those associated with an SNA type 2.0 node (or with a boundary
function-attached type 2.1 node), however, 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 defined by RFC 2012 (Refer to reference
[10], 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, Tn3270eTAddress
and Tn3270eAddrType 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, the tn3270eConfSpinLock object provides an
advisory lock that an implementation MAY use to let cooperating
TN3270E-MIB applications coordinate their use of the
tn3270eSrvrConfTable, the tn3270eSrvrPortTable, the
tn3270eClientGroupTable, the tn3270eResPoolTable, and the
tn3270eClientResMapTable.  When an application seeks to create a new
entry or alter an existing entry in any of the above mentioned tables,
an implementation MAY require the application to use the
tn3270eConfSpinLock to serialize its changes or additions relative to
those initiated by other applications.  Since this is an advisory lock,
an implementation is not required to support it.

3.5  IANA Considerations

The tn3270eSrvrFunctionsSupported, tn3270eTcpConnFunctions,
tn3270eTcpConnClientIdFormat, and tn3270eTcpConnLogInfo objects 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 Number 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.

The current version of the IANATn3270eTC-MIB can be accessed from the
IANA homepage at: "http://www.iana.org/iana/".

         period ('.'), and a 1 to 8 character resource name
         (ResName).

         The NetId and ResName are constructed from the
         uppercase letter '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 ResNames:  '#', '@', and '$'.
         While this use of these characters has been retired,
         a Management Station should still accept them for

         all of its TN3270 and TN3270E sessions during termination

    DESCRIPTION
        "This object indicates the type of TN3270E server.
        The existence of MIB tables and objects that will be
        defined by follow-on MIBs may be predicated on whether
        the TN3270E server can be local to the same host as a
        target application (host(1)) or will always be remote
        (gateway(2)).

        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 an SNA network.

        A gateway TN3270E server resides on an SNA node other
        than an SSCP, either an SNA type 2.0 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) requirements."

        "A collection of statistical objects for a single

        the activity occurring at the server on either
        a port or port-and-local-address basis.
        Refer to the text description for tn3270eSrvrPortEntry.

        Collection of the statistics represented by the objects
        in this table is not mandatory.  An implementation may
        limit itself to keeping global statistics for a TN3270E
        server.  The indexing for the row containing these
        global server statistics is as follows:

             tn3270eSrvrConfIndex       value identifying the server
             tn3270eSrvrPort            0

             tn3270eSrvrPortAddress     zero-length octet string.

        The values of the following objects are implementation-
        dependent for statistics that are being kept on either
        a port or port-and-local-address basis:

         Returning a zero is misleading.  Support of these
         objects is recommended when the Counter32 versions
         can potentially wrap too frequently.

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

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.  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 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:

o   tn3270eSrvrConfInactivityTimout
o   tn3270eSrvrConfActivityCheck
o   tn3270eSrvrConfActivityTimeout
o   tn3270eSrvrConfActivityInterval
o   tn3270eSrvrConfAdminStatus
o   tn3270eSrvrConfSessionTermState
