Management information for 802.3 repeaters.

The following references are used throughout this MIB module:

[IEEE 802.3 Std] refers to IEEE 802.3/ISO 8802-3 Information processing systems - Local area networks - Part 3: Carrier sense multiple access with

collision detection (CSMA/CD) access method and physical layer specifications (1993).

[IEEE 802.3 Mgt] refers to IEEE 802.3u-1995, '10 Mb/s & 100 Mb/s Management, Section 30,' Supplement to ANSI/IEEE 802.3.

The following terms are used throughout this MIB module. For complete formal definitions, the IEEE 802.3 standards should be consulted wherever possible:

System - A managed entity compliant with this MIB, and incorporating at least one managed 802.3 repeater.

Chassis - An enclosure for one managed repeater, part of a managed repeater, or several managed repeaters. It typically contains an integral power supply and a variable number of available module slots.

Repeater-unit - The portion of the repeater set that is inboard of the physical media interfaces. The physical media interfaces (MAUs, AUIs) may be physically separated from the repeater-unit, or they may be integrated into the same physical package.

Trivial repeater-unit - An isolated port that can gather statistics.

Group - A recommended, but optional, entity defined by the IEEE 802.3 management standard, in order to support a modular numbering scheme. The classical example allows an implementor to represent field-replaceable units as groups of ports, with the port numbering matching the modular hardware implementation.

System interconnect segment - An internal segment allowing interconnection of ports belonging to different physical entities into the same logical manageable repeater. Examples of implementation might be backplane busses in modular hubs, or chaining cables in stacks of hubs.

Stack - A scalable system that may include managed repeaters, in which modularity is achieved by interconnecting a number of different chassis.

Module - A building block in a modular chassis. It typically maps into one 'slot'; however, the range of configurations may be very large, with several modules entering one slot, or one module covering several slots.
