- 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.
