DIFFSERV-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
        "This MIB module contains differentiated services
        specific managed objects to perform higher-level
        configuration management.  This MIB allows policies
        to use 'templates' to instantiate Differentiated
        Services functional datapath configurations to
        be assigned (associated with an interface and
        direction) when a policy is activated.

        of this MIB module is part of RFC 3747;  see the RFC
        itself for full legal notices."

       Since an entry in this table serves as a starting
       point for a configuration, it is recommended that
       all entries comprising the configuration started by
       diffServConfigStart follow the storage type of this
       entry.  Otherwise, after agent reboots a configuration
       may differ.  It may very well be that the agent is
       not capable of detecting such changes and therefore,
       the management application should verify the correct
       configuration after a reboot.  Rows with a StorageType
       of 'permanent' do not need to allow write access to
       any of the columnar objects in that row."
