INTERNET-DRAFT            DS1 Supplemental MIB                  May 1996


Abstract

   This memo defines an experimental portion of the Management
   Information Base (MIB) for use with network management protocols in
   the Internet community.  In particular, it describes additional
   objects that supplement those defined in the Definitions of Managed
   Objects for the DS1, E1, DS2 and E2 Interface Types document,
   RFC<TBD> [1].

   This memo specifies a MIB module in a manner that is both compliant
   to the SNMPv2 SMI, and semantically identical to the peer SNMPv1
   definitions.

   This memo does not specify a standard for the Internet community.


1.  The SNMP Network Management Framework

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

   o    the SMI, described in RFC 1902 [2] - the mechanisms used for
        describing and naming objects for the purpose of management.

   o    the MIB-II, STD 17, RFC 1213 [3] - the core set of managed
        objects for the Internet suite of protocols.

   o    the protocol, RFC 1157 [4] and/or RFC 1905 [5], - the protocol
        for accessing managed objects.

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



1.1.  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 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 also refer to
   the object type.

INTERNET-DRAFT            DS1 Supplemental MIB                  May 1996


2.  Overview

   The objects in this supplemental MIB apply to interfaces of types
   DS1, E1, DS2 and E2. The definitions in this MIB provide an SNMP-
   compatible interface to the features described in ANSI T1.231 [6]
   that are not in the existing DS1-MIB [1]. These features include:

   o    thesholding

   o    additional valid data flags

   o    a table for previous and recent day history

   o    objects for resetting parameters

   In addition, this memo contains a short MIB module containing
   definitions that are anticipated to be common when similar
   supplemental MIBs are defined for the DS3/E3 and SONET interface
   types.

         DESCRIPTION
             "The MIB module containing definitions for DS1, E1, DS2, and
             E2 interfaces that supplement those in the standard
             DS1-MIB. (DS1-like interfaces are refered to generically in
             this memo as 'DS1 interfaces'.)

             The objects defined in this MIB module were identified by
             examining ANSI T1.231-1993 and identifying functionality that
             was not specified in the standard DS1-MIB. In addition, the
             Bellcore GR-820-CORE document was consulted, specifically to
             determine the conformance statements.

             Implementing this MIB is optional in a managed device
             that has these types of interfaces because of the additional
             processing and storage capabilities that are required. The
             management functions described in this memo are particularly
             appropriate for 'mediation devices' associated with managed
             device. (See ANSI T1.231-1993, Section 9.1.2.)"

             In general, allowing objects that are statistics to be reset
             to 0 is highly discouraged in SNMP MIBs. This is primarily
             because there may be multiple managers monitoring a given
             agent. The physical layer performance parameters are already
             exceptional, however, because they are hybrid counter/gauges:
             they behave as counters within a given interval and then
             automatically reset to 0 after the interval is over. Unlike
             when polling counters, a manager would not get 'confused' by
             the value of a performance parameter going back to 0.

             Also, the ability to reset performance parameters is stated as
             a firm requirement in the reference documents and not allowing
             reset would make it difficult to implement the required
             thresholding behavior of only sending one Threshold Crossing
             Alert (TCA) message in a given interval unless the parameters
             are reset."

             objects. Note that these last two vary based on the parameter
             and the interval and therefore are not specified explicitly in
             the OBJECTS list.

             Note that the sysUpTime and sysTrapOID objects are always
             included in every Trap PDU's variable bindings list.
