    STATUS      current
    DESCRIPTION
        "The 16-bit integer value which is the proposed Hello
        hold timer for this LDP Entity. The Hello Hold time
        in seconds.



        An LSR maintains a record of Hellos received
        from potential peers.  This object represents
        the Hold Time in the Common Hello Parameters TLV of
        the Hello Message.

        A value of 0 is a default value and should be
        interpretted in conjunction with the
        mplsLdpEntityTargetPeer object.

        If the value of this object is 0: if the value of the
        mplsLdpEntityTargetPeer object is false(2), then this
        specifies that the Hold Time's actual default value is
        15 seconds (i.e., the default Hold time for Link Hellos
        is 15 seconds).  Otherwise if the value of the
        mplsLdpEntityTargetPeer object is true(1), then this
        specifies that the Hold Time's actual default value is
        45 seconds (i.e., the default Hold time for Targeted
        Hellos is 45 seconds).

        A value of 65535 means infinite (i.e., wait forever).

        All other values represent the amount of time in
        seconds to wait for a Hello Message.  Setting the
        hold time to a value smaller than 15 is not
        recommended, although not forbidden according
        to RFC3036."

mplsLdpEntityInitSessionThreshold OBJECT-TYPE

    MAX-ACCESS  read-create
    STATUS      current
    DESCRIPTION
        "When attempting to establish a session with
        a given Peer, the given LDP Entity should
        send out the SNMP notification,
        'mplsLdpInitSessionThresholdExceeded', when
        the number of Session Initialization messages
        sent exceeds this threshold.

        The notification is used to notify an
        operator when this Entity and its Peer are
        possibly engaged in an endless sequence
        of messages as each NAKs the other's



        Initialization messages with Error Notification
        messages.  Setting this threshold which triggers
        the notification is one way to notify the
        operator.  The notification should be generated
        each time this threshold is exceeded and
        for every subsequent Initialization message
        which is NAK'd with an Error Notification
        message after this threshold is exceeded.

        A value of 0 (zero) for this object
        indicates that the threshold is infinity, thus
        the SNMP notification will never be generated."
