Internet Draft DTR Concentrator MIB August 1996
Abstract
This document contains an extract from Draft 5 of the IEEE stan-
dard 802.5R "Dedicated Token Ring". The extract comprises the
MIB for the Dedicated Token Ring Concentrator, in SNMPv2 format.
802.5R is a standard that encompasses the existing 802.5 token-
passing method of operation, and also defines a new duplex method of
operation for use only on dedicated point to point links, that does
not use tokens for data transmission.
The architecture of a DTR Concentrator is defined in the 802.5R
standard. It is a MAC layer bridging device, which uses a new set
of forwarding rules that ease interoperability between source rout-
ing and transparent bridging in an 802.5 LAN. The DTR Concentrator
MIB is derived from the Source Routing and Transparent Bridge MIBs
(RFCs 1525 and 1493).
Background
This MIB is being made available as an Internet draft to allow wider
public comment on its format.
In the past, SNMP MIBs for IEEE 802 standards have been written by
members of the IETF Network Management Working Group, on the basis of
GDMO management information in the IEEE document. However, in this
case, the draft IEEE 802.5R standard contains its management informa-
tion in SNMP MIB format.
The draft IEEE standard 802.5R is currently going through a set of
revisions based on Working Group comments on Draft 4. All comments
pertaining to the Interface MIB have been applied to produce a Draft
5 version of this section of the document, which is included below.
The 802.5 Working Group's intent is that Draft 5 will be the final
draft of 802.5R before it is submitted for ratification by the IEEE
standards board and ISO.
Brief Introduction to Dedicated Token Ring
The operation of Dedicated Token Ring (DTR) involves communication
between two distinct entities. These are the DTR Station, and the DTR
Concentrator Port (C-Port). A DTR link consists of one DTR Station
and one C-Port. To provide links between DTR Concentrators, a C-Port
may act as a DTR Station (C-Port in Station Emulation Mode).
When operating as a dedicated link, there is no token passing, and
the Transmit Immediate (TXI) function is used to transmit data.
Lee and Warwick [Page 2]
Internet Draft DTR Concentrator MIB August 1996
In addition, DTR Stations and C-Ports are required to be able to sup-
port token-passing (TKP) operation, also referred to as Classic Token
Ring operation.
Stations and C-Ports will automatically detect the appropriate access
protocol to use when they are enabled.
In summary, DTR provides a way of connecting a Station to a Concen-
trator on a dedicated link with an aggregate throughput of 32
MBits/sec, and also provides backwards compatibility with shared
media token passing operation at 16 or 4 MBits/sec.
A DTR Concentrator may provide a MAC layer relay service between any
mixture of DTR links and Classic 802.5 rings.

--*****************************************************************
-- This SNMP MIB Module contains definitions for management of a DTR
-- Concentrator. The MIB consists of the following groups:
-- Base DTR Concentrator Information (mandatory)
-- DTR Concentrator Spanning Tree Information (optional)
-- DTR Concentrator Forwarding Information (optional)
-- DTR Concentrator MRI Information (optional)
-- DTR Concentrator Statistics Information (optional)
--*****************************************************************
-- Relationship to RFC1493
-- RFC1493 is not used for management of any CRF object. However, if
-- a Bridge Relay Function is defined for the DTR Concentrator, the
-- Bridge MIB is used for the Bridge Relay Function.
-- Relationship to RFC1573
-- Layering Model
-- This MIB describes the Concentrator Relay Function (CRF) which
-- operates based on addressing and other information supplied by the
-- "lower layer" data frame. For the purposes of RFC1573, the CRF
-- constitues an "upper layer" protocol which operates by aggregating
-- several physical C-Ports (interfaces) and at most one logical
-- interface to an optional internal Bridge Relay Function
-- (interface) into a logical entitiy. The same CRF can be defined
Lee and Warwick [Page 4]
Internet Draft DTR Concentrator MIB August 1996
-- as the upper layer for multiple interfaces. A given C-Port or
-- internal Bridge Relay Function interface will provide data to only
-- a single CRF.
Virtual Circuits
-- The CRF does not support virtual circuits
-- ifTestTable
--The CRF does not implement tests via SNMP
-- ifRcvAddressTable
-- For interfaces that correspond to a C-Port: The C-Port operates in
-- promiscous mode, hence this table will contain only the all station
-- broadcast address, functional address bit mask (if any are enabled),
-- and the C-Port individual address. Note that MAC traffic targeted
-- to this C-Port entry is not forwarded to the CRF.
-- Bridge Relay Function interfaces are not implemented in this table.
-- ifType
-- Additional IANAifType enumerated values are required for this MIB.
-- These enumerated values correspond to the following:
-- C-Port Interface (86)
-- Internal Bridge Relay interface (98)
-- This MIB maps dtrCRFPortType to ifType in RFC1573.
