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].

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.
