CISCO-XDSL-LINE-MIB device MIB details by Cisco

CISCO-XDSL-LINE-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.

    DESCRIPTION
        "The tables defined by this MIB module contain a collection
        of managed objects that are general in nature and apply to
        different types of modems. The structure of this module
        resembles the  ADSL-LINE-MIB, CISCO-SDSL-LINE-MIB, 
        ADSL-DMT-LINE-MIB, CISCO-ADSL-DMT-LINE-MIB, etc. 
        Observe that the tables in this module do not necessarily
        extend the tables defined by the these mibs. Currently,
        only the table that contains the configuration information 
        extends the profile tables defined by the above modules. 
     
        Mib objects must fulfill the following criteria to be
        contained in this mib module:

        1)  The ADSL-LINE-MIB or the modem specific mibs such as
            CISCO-SDSL-LINE-MIB, CISCO-ADSL-DMT-LINE-MIB, etc.
            does not already contain a managed object
            representing the same information.

        2) The mibs object must NOT be technology dependent, they 
           must apply to various types of DSL modems,
           e.g. IDSL, SDSL, ADSL, etc.  

        *** ABBREVIATIONS, ACRONYMS, AND SYMBOLS ***

        ADSL - Asymmetric Digital Subscriber Line.

        ATM - Asynchronous Transfer Mode.

        XTU-C - xDSL Transceiver Unit, Central Office end.

        XTU-R - xDSL Transceiver Unit, Remote terminal end.

        BER - Bit Error Ratio.

        BERT - Bit Error Ratio Test.
   
        DSP - Digital Signal Processor.

        DSL - Digital Subscriber Line.

        IDSL - IDSN Digital Subscriber Line.

        SDSL - Symetric Digital Subscriber Line.

        xDSL - Group term used to refer to ADSL, HDSL, SDSL, VDSL,
               IDSL, etc. All are digital technologies using existing
               copper lines provided by the thelephone companies."
