At this stage the new RuleSet is available but not 'running', i.e. it is not being used by the meter to produce entries in the flow table. To actually 'run' a RuleSet a manager must create a row in the flowManagerInfoTable, set it's flowManagerStatus to active(1), and set either its CurrentRuleSet or StandbyRuleSet to point to the RuleSet to be run. Once a RuleSet is running a manager may not change any of the objects within the RuleSet itself. Any attempt to do so should result in a notWritable(17) SNMP error-status for such objects. A manager may stop a RuleSet running by removing all references to it in the flowManagerInfoTable (i.e. by setting CurrentRuleSet and StandbyRuleSet values to 0). This provides a way to stop RuleSets left running if a manager fails. For example, when a manager is started, it could search the meter's flowManager table and stop all RuleSets having a specified value of flowRuleInfoOwner. To prevent a manager from interfering with variables belonging to another manager, the meter should use MIB views [RFC2575] so as to limit each manager's access to the meter's variables, effectively dividing the single meter into several virtual meters, one for each independent manager." ::= { flowControl 1 } flowRuleSetInfoEntry OBJECT-TYPE SYNTAX FlowRuleSetInfoEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Information about a particular 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.

Set to N to count 1/Nth of the packets appearing at this interface. A sampling rate of 1 counts all packets. 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."

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.

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)."
