flowRuleInfoSize OBJECT-TYPE
    SYNTAX  Integer32

    DESCRIPTION
        "Number of rules in this RuleSet.  Setting this variable will

flowRuleInfoOwner OBJECT-TYPE
    SYNTAX  UTF8OwnerString
    MAX-ACCESS  read-create
    STATUS  current
    DESCRIPTION
        "Identifies the manager which 'owns' this RuleSet.  A manager

flowRuleInfoTimeStamp OBJECT-TYPE
    SYNTAX  TimeStamp
    MAX-ACCESS  read-only

    ::= { flowRuleSetInfoEntry 4 }

flowRuleInfoStatus OBJECT-TYPE
    SYNTAX  RowStatus
    MAX-ACCESS  read-create
    STATUS  current
    DESCRIPTION
        "The status of this flowRuleSetInfoEntry. If this value is
        not active(1) the meter must not attempt to use the row's
        associated RuleSet.  Once its value has been set to active(1)
        a manager may not change any of the other variables in the
        row, nor the contents of the associated RuleSet.  Any attempt
        to do so should result in a notWritable(17) SNMP error-status
        for such variables or objects.

        To download a RuleSet, a manger could:
           - Locate an open slot in the RuleSetInfoTable.
           - Create a RuleSetInfoEntry by setting the status for this
               open slot to createAndWait(5).
           - Set flowRuleInfoSize and flowRuleInfoName as required.
           - Download the rules into the row's rule table.
           - Set flowRuleInfoStatus to active(1).

        The RuleSet would then be ready to run. The manager is not
        allowed to change the value of flowRuleInfoStatus from
        active(1) if the associated RuleSet is being referenced by any
        of the entries in the flowManagerInfoTable.

        Setting RuleInfoStatus to destroy(6) destroys the associated
        RuleSet together with any flow data collected by it."

        identify a RuleSet.  For example, a manager wishing to run a
        RuleSet named WWW-FLOWS could search the flowRuleSetInfoTable
        to see whether the WWW-FLOWS RuleSet is already available on
        the meter.

        Note that references to RuleSets in the flowManagerInfoTable
        use indexes for their flowRuleSetInfoTable entries.  These may
        be different each time the RuleSet is loaded into a meter."

        A sampling rate of 0 results in the interface being ignored
        by the meter.

        A meter should choose its own algorithm to introduce variance
        into the sampling so that exactly every Nth packet is counted.
        The IPPM Working Group's RFC 'Framework for IP Performance
        Metrics' [IPPM-FRM] explains why this should be done, and sets
        out an algorithm for doing it."

-- Control Group:  Meter Reader Info Table
--

-- Any meter reader wishing to collect data reliably for flows
-- should first create a row in this table.  It should write that
-- row's flowReaderLastTime object each time it starts a collection
-- pass through the flow table.

-- If a meter reader (MR) does not create a row in this table, e.g.
-- because its MIB view [RFC2575] did not allow MR create access to
-- flowReaderStatus, collection can still proceed but the meter will
-- not be aware of meter reader MR.  This could lead the meter to
-- recover flows before they have been collected by MR.

    DESCRIPTION
        "Specifies the maximum time (in seconds) between flow data

    DESCRIPTION
        "Time this meter reader began its most recent data collection.

        This variable should be written by a meter reader as its first
        step in reading flow data.  The meter will set this LastTime
        value to its current Uptime, and set its PreviousTime value
        (below) to the old  LastTime.  This allows the meter to
        recover flows which have been inactive since PreviousTime,
        for these have been collected at least once.

        If the meter reader fails to write flowLastReadTime, collection
        may still proceed but the meter may not be able to recover
        inactive flows until the flowReaderTimeout has been reached

-- Control Group:  Manager Info Table
--

-- Any manager wishing to run a RuleSet must create a row in this
-- table.  Once it has a table row, the manager may set the control
-- variables in its row so as to cause the meter to run any valid
-- RuleSet held by the meter.

-- A single manager may run several RuleSets; it must create a row
-- in this table for each of them.  In short, each row of this table
-- describes (and controls) a 'task' which the meter is executing.

flowManagerInfoEntry OBJECT-TYPE
    SYNTAX  FlowManagerInfoEntry
    MAX-ACCESS  not-accessible
    STATUS  current
    DESCRIPTION
        "Information about a particular meter 'task.'  By creating
        an entry in this table and activating it, a manager requests
        that the meter 'run' the indicated RuleSet.

        The entry also specifies a HighWaterMark and a StandbyRuleSet.
        If the meter's flow table usage exceeds this task's
        HighWaterMark the meter will stop running the task's
        CurrentRuleSet and switch to its StandbyRuleSet.

        If the value of the task's StandbyRuleSet is 0 when its
        HighWaterMark is exceeded, the meter simply stops running the
        task's CurrentRuleSet.  By careful selection of HighWaterMarks
        for the various tasks a manager can ensure that the most
        critical RuleSets are the last to stop running as the number
        of flows increases.

        When a manager has determined that the demand for flow table
        space has abated, it may cause the task to switch back to its
        CurrentRuleSet by setting its flowManagerRunningStandby
        variable to false(2)."
