1. Introduction

This memo defines an extension to the Management Information Base
(MIB) for use with network management protocols in the Internet
community. In particular, it defines objects for the management of
coffee-brewing and maintenance devices.

2. The SNMPv2 Network Management Framework

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

o RFC 1442 [1] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.

Slavitch Informational [Page 1]

RFC 2325 CP MIB 1 April 1998

o STD 17, RFC 1213 [2] defines MIB-II, the core set of managed
objects for the Internet suite of protocols.

o RFC 1445 [3] which defines the administrative and other
architectural aspects of the framework.

o RFC 1448 [4] which defines the protocol used for network
access to 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 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

The COFFEE POT MIB applies to managed devices that brew, store, and
deliver heated coffee beverages. The COFFEE POT MIB is mandatory for
all systems that have such a hardware port supporting services
managed through some other MIB.

The MIB contains objects that relate to physical connections,
configuration, storage levels, availabilty, quality of service, and
availability.

3.1. Relationship to Interface MIB

The COFFEE-POT-MIB is one of many MIBs designed for layered use as
described in the Interface MIB [5]. In most implementations where it
is present, it will be in the lowest interface sublayer, that is, the
COFFEE-POT-MIB represents the physical layer, providing service to
higher layers such as the Character MIB [6].

Although it is unlikely that a coffee port will actually be used as a
network interface, which is the intent of the Interface MIB, the
COFFEE-POT-MIB is closely connected to the Character MIB, which can
share hardware interfaces with network operation, and relate to the
RS-232 MIB [7].

Slavitch Informational [Page 2]

RFC 2325 CP MIB 1 April 1998

The Interface MIB's ifTestTable and ifRcvAddressTable are not
relevant to the COFFEE-POT-MIB.

The COFFEE-POT-MIB is relevant for ifType values sip(31), and perhaps
others.

The COFFEE-POT-MIB requires the conformance groups ifGeneralGroup,
and ifFixedLengthGroup.

Usefulness of error counters in this MIB depends on the octet
counters in ifFixedLengthGroup.
