1. Introduction
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 managed objects
to record and retrieve ATM performance history data recorded in 15
minute interval. The functionality defined in this document is
intended to satisfy the requirements defined by the ATM Forum in [9].
2. The SNMP Network Management Framework
Expires April 1997 [Page 1]
Internet-Draft ATM Performance History MIB November 1996
The SNMP Network Management Framework presently consists of three
major components. They are:
the SMI, described in RFC 1902 [1] - the mechanisms used for
describing and naming objects for the purpose of management.
the MIB-II, STD 17, RFC 1231 [2] - the core set of managed objects
for the Internet suite of protocols.
the protocol, RFC 1157 [3] and/or RFC 1905 [4], - the protocol for
accessing managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
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 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. Overview
This document defines a Management Information Base (MIB) for
recording and retrieving ATM performance history data recorded in 15
minute intervals. The functionality defined in this document is
intended to meet the requirements defined by the ATM Forum in [9].
Six tables are provided:
ATM Cell Layer Current Data (per interface)
ATM Cell Layer History Data (per interface and time interval)
VPL UPC/NPC Current Data (per VPL termination point)
VPL UPC/NPC History Data (per VPL termination point and time interval)
VCL UPC/NPC Current Data (per VCL termination point)
VCL UPC/NPC History Data (per VCL termination point and time interval)
