MPLS-LDP-FRAME-RELAY-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.

        both directions independently.  If the value of

        Parameter, field D (for VC Directionality).  The
        Frame Relay Session Parameter is an optional

        The description from rfc3036.txt is:

        'D, VC Directionality
           A value of 0 specifies bidirectional VC capability,
           meaning the LSR can support the use of a given
           DLCI as a label for both link directions
           independently.  A value of 1 specifies
           unidirectional VC capability, meaning a given
           DLCI may appear in a label mapping for one
           direction on the link only.  When either or both
           of the peers specifies unidirectional VC
           capability, both LSRs use unidirectional VC
           label assignment for the link as follows.  The
           LSRs compare their LDP Identifiers as unsigned
           integers.  The LSR with the larger LDP
           Identifier may assign only odd-numbered DLCIs
           in the range as labels.  The system with the
           smaller LDP Identifier may assign only
           even-numbered DLCIs in the range as labels.'
