MPLS-LDP-FRAME-RELAY-STD-MIB device MIB details by RFC
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.

The value of zero means that the InterfaceIndex is not known. For example, if the InterfaceIndex is created subsequent to the Frame Relay Label's creation, then it would not be known. However, if the InterfaceIndex is known, then it must be represented by this value. If an InterfaceIndex becomes known, then the network management entity (e.g., SNMP agent) responsible for this object MUST change the value from 0 (zero) to the value of the InterfaceIndex.

If the value of this object is 'unidirectional(1)', then the LSR uses the given DLCI as a label in only one direction. This is the EXACT value for the Frame Relay Session Parameter, field D (for VC Directionality). The Frame Relay Session Parameter is an optional parameter in the Initialization Message. 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.' Please refer to the following reference for a complete description of this feature."
