MPLS-LDP-GENERIC-STD-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.

        The purpose of this table is to provide a mechanism
        for configurating a contiguous range of generic labels,
        or a 'label range' for LDP Entities.

        LDP Entities which use Generic Labels must have at least
        one entry in this table.  In other words, this table
        'extends' the mpldLdpEntityTable for Generic Labels."

        in this table, however, this table does provide
        a way for a user to 'reserve' a generic label
        range.

        NOTE:  The ranges for a specific LDP Entity
        are UNIQUE and non-overlapping.

         entitled, 'Changing Values After Session
         Establishment', and again described in the
         DESCRIPTION clause of the mplsLdpEntityAdminStatus object,
         if a session has been initiated with a Peer,
         changing objects in this table will
         wreak havoc with the session and interrupt traffic.
         To repeat again:  the recommended procedure is
         to set the mplsLdpEntityAdminStatus to
         down, thereby explicitly causing a
         session to be torn down. Then, change objects
         in this entry, then set the mplsLdpEntityAdminStatus
         to enable which enables a new session to be initiated.

         There must exist at least one entry in this
         table for every LDP Entity that has a
         generic label configured."
