CISCO-IF-LINK-CONFIG-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 MIB module for configuration of bulk distribution
         (de-multiplexing of traffic from higher-bandwidth to 
         lower-bandwidth interfaces).

         Terminology :

         bulk-distribution        : The bulk distribution is the 
                                    feature by which a line/interface
                                    on one module can replace the line
                                    for the other.

         bulk-distribution module : The module which links its 
                                    interfaces to the target module.

         target module            : A module that gets incoming traffic
                                    from a bulk distribution module 
                                    rather than from a back card.
                      
         The Module which supports bulk distribution, converts 
         traffic from its lines (may be T3, OC-N) to lines on 
         the target module (may be
         T3, T1 etc). The bulk distribution is achieved by having a 
         point-to-point connection (bulk-distribution bus) between the 
         bulk-distribution module and the target module. The benefit 
         of bulk distribution is that the target module need not have
         the back cards. The lines/interfaces from bulk-distribution
         module will be used as lines for the target module.

         An example is given here on linking interfaces.
