Internet Draft DTR MIB                                     December 1997


Abstract

   This document  contains  an  extract from the approved text of IEEE
   standard 802.5R ''Dedicated Token Ring''.   The  extract  comprises
   the  Interface MIB for the Dedicated Token Ring interface, in SNMPv2
   format. There are no changes to the MIB from the Draft 7 version.


   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.

Background

   In the past, SNMP Interface 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 information in SNMP MIB format.

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.

   In addition, DTR Stations and C-Ports are required to be able to
   support 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
   Concentrator 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.

-- Relationship to RFC1573

-- Layering Model
--    For the typical usage of this IEEE 802.5 DTR MIB module,
--    there will be no sublayers "above" or "below" the 802.5
--    DTR interface.  However, this MIB module does not preclude
--    such layering.

-- Virtual Circuits
--    802.5 DTR does not support virtual circuits.

-- ifTestTable
--    This MIB Module does not define tests.

-- ifRcvAddressTable
--    The ifRcvAddressTable is defined to contain all MAC
--    addresses, unicast, multicast (group) and broadcast, for
--    which an interface will receive packets.  For 802.5 DTR
--    interfaces, its use includes functional addresses.  The

Internet Draft DTR MIB                                     December 1997


--    format of the address, contained in ifRcvAddressAddress is
--    the same as for ifPhysAddress.

--    For functional addresses on a particular 802.5 DTR
--    interface, only one ifRcvAddressTable entry is required.
--    That entry is the one for the address which has the
--    functional address bit ANDed with the bit mask of all
--    functional address for which the interface will accept
--    frames.

-- ifPhysAddress
--    For an 802.5 DTR interface, ifPhysAddress contains the
--    interface's IEEE MAC address, stored as an octet string of
--    length 6, in IEEE 802.1a "canonical" order, i.e., the Group
--    Bit is positioned as the low-order bit (0x01) of the first
--    octet.

-- ifType
--    The objects defined in this MIB Module apply to each
--    interface for which the ifType has the value:
--       iso88025Dtr = 86

--*********************************************************
-- TXI Protocol
--   This table provides information about an 802.5 TXI MAC.
--   A managed system will have one entry in this table
--   for each of its TXI MAC interfaces.  It is mandatory
--   that systems having TXI interfaces implement this
--   table in addition to the generic interfaces table and
--   its generic extensions, defined in RFC-1573.
