DS3-MIB device MIB details by RFC

DS3-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

      (3) Usage of ifStackTable section was updated.

      (4) Align the DESCRIPTION clauses of few statistic objects with
          thenear end definition, the far end definition and with
          RFC 3593.

     DESCRIPTION
          "The RFC 2496 version of this MIB module.
          The key changes made to this MIB module
          since its publication in RFC 1407 are as follows:

         (1)  The Fractional Table has been deprecated.

         (2)  This document uses SMIv2.

         (3)  Values are given for ifTable and ifXTable.

         (4)  Example usage of ifStackTable is included.

         (5)  dsx3IfIndex has been deprecated.

         (6)  The definition of valid intervals has been clarified
              for the case where the agent proxied for other devices.
              In particular, the treatment of missing intervals has
              been clarified.

        (7)  An inward loopback has been added.

        (8)  Additional lineStatus bits have been added for Near End
             in Unavailable Signal State, Carrier Equipment Out of
             Service.

        (9)  A read-write line Length object has been added.

        (10) Added a lineStatus last change, trap and enabler.

        (11) Textual Conventions for statistics objects have
             been used.

        (12) A new object, dsx3LoopbackStatus, has been introduced to
             reflect the loopbacks established on a DS3/E3 interface
             and the source to the requests.  dsx3LoopbackConfig
             continues to be the desired loopback state while
             dsx3LoopbackStatus reflects the actual state.

        (13) A dual loopback has been added to allow the setting of
             an inward loopback and a line loopback at the same time.

        (14) An object has been added to indicated whether or not
             this is a channelized DS3/E3.

        (15) A new object has been added to indicate which DS1 is to
             set for remote loopback."

    DESCRIPTION
            "This table is deprecated in favour of using
            ifStackTable.

            Implementation of this table was optional.  It was
            designed for those systems dividing a DS3/E3 into
            channels containing different data streams that
            are of local interest.

            The DS3/E3 fractional table identifies which
            DS3/E3 channels associated with a CSU are being
            used to support a logical interface, i.e., an
            entry in the interfaces table from the Internet-
            standard MIB.

            For example, consider a DS3 device with 4 high
            speed links carrying router traffic, a feed for
            voice, a feed for video, and a synchronous channel
            for a non-routed protocol.  We might describe the
            allocation of channels, in the dsx3FracTable, as
            follows:
            dsx3FracIfIndex.2. 1 = 3  dsx3FracIfIndex.2.15 = 4
            dsx3FracIfIndex.2. 2 = 3  dsx3FracIfIndex.2.16 = 6
