CISCO-CDL-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 defines objects to manage Converged Data Link
        (CDL).

        CDL provides OAM&P (Operation, Administration, Maintenance and
        Provisioning) in Ethernet packet-based optical networks without
        a SONET/SDH layer.

        The CDL functionality can be divided into the following
        categories:

        APS/Defect Indications:
           The CDL frame carries defect indication bits and provides
           signalling mechanism support for automatic protection
           switching.

        Message Channel:
           The message channel is used to carry control (e.g. routing,
           signalling) and management traffic.

        Packet-by-packet multiplexing of multiple data flows:
           CDL uses one or two octets to identify the elementary 
           packet stream that this packet belongs to. This allows 
           more than one elementary packet stream to share the 
           bandwidth on a CDL enabled interface.

        This MIB defines objects to manage Defect Indications and the
        Packet-by-packet Multiplexing feature.

        The CDL Message channel is modeled as a separate interface and
        should be controlled using the IF-MIB and other MIBs for
        managing IP. This MIB does not provide a mechanism to manage
        the CDL message channel.

        APS configuration and monitoring can be done using the
        CISCO-APS-MIB and CISCO-APS-EXT-MIB.

CoCdlNodeBehavior ::= TEXTUAL-CONVENTION

        "A network element can take on one of three roles for each CDL

            endOfHop
            endOfAggPath
            cdlRegenerator

        endOfHop: Indicates that this network element acts as a CDL
            Hop Terminating Network Element but not as a CDL Aggregate
            Path Terminating Network Element, at this interface.  A CDL
            Hop Terminating Network Element is a network element that
            terminates (generates in one direction and consumes in
            another direction) OAM information associated with a Hop
            at an interface.

            A network element will be designated a Hop Terminating
            Network Element at an interface only if it meets one of the
            following conditions:

            (1) It is an Aggregate Path Terminating Network Element,

            (2) It carries out Hop-by-hop Automatic Protection
                Switching (APS), or

            (3) It has been configured to be a Hop Terminating Network
                Element.  This may be desirable at administrative
                boundaries between networks, for example, in order to
                limit the span of the hop-by-hop backward defect
                indication to the interface between the two networks.

        endOfAggPath: Indicates that this network element acts as a
            CDL Aggregate Path Terminating Network Element that
            terminates (generates in one direction and consumes in
            another direction) OAM information associated with an
            Aggregate Path (as well as OAM information associated with
            a Hop), at this interface.

            A network element will be designated an Aggregate Path
            Terminating network element at an interface only if it:

            (1) applies/removes the CDL Ethernet encapsulation, or

            (2) demultiplexes the arriving aggregate packet stream
                into elementary packet streams, and multiplexes two
                or more elementary packet streams into the departing
                packet stream.

        cdlRegenerator:
            A CDL Regenerator transmits a regenerated input packet
            stream. It monitors integrity of the CDL header and
            generates CDL alarms (FDI-H) if the incoming packet stream
            fails. It also terminates the CDL Message Channel.

        When this object is set to 'true', CDL is enabled on 
        this interface. When this object is set to 'false', 
        CDL is disabled on this interface.

        When CDL is enabled, the following actions are taken:
        1) When a non-CDL packet is progressed to this interface for
           transmission, the Ethernet packet is modified to carry the
           CDL header. Similarly, when a received packet is progressed
           from this interface to a non-CDL interface, the CDL header
           is removed from the Ethernet packet.
        2) Processing of CDL defect indications is activated.
        3) The CDL Message Channel used to carry control (e.g. routing,
           signalling) and management traffic is activated. The SNMP
           agent creates an interface that represents the CDL Message
           Channel. The interface representing the CDL Message Channel
           is shown as a higher layer interface, with ifType
           'propPointToPointSerial', residing above this CDL enabled
           interface in the ifStackTable in the IF-MIB.
        4) The CDL APS Channel is activated, if supported and APS is
           configured for this interface.
        5) Transport of multiple data flows (i.e. packet-by-packet
           multiplexing) is activated, if this capability is supported
           on this interface.

        When CDL is disabled, only traditional (non-CDL) Ethernet
        packets are transported, all packets on this interface are
        treated as one Ethernet data flow, and the interface
        representing the CDL message channel is deleted.

        Element terminates (generates in one direction and consumes in

        interface.

        When this object is set to 'false', this network element may

        administrative boundaries. This ensures that the hop-by-hop
        CDL Defect Indications (FDI-H and BDI-H) between two
        administrative domains reflect only errors that occur between

            A coCdlFromCdlNetFlowDIChange notification is generated

        To minimize the probability of prematurely reacting to
