flowRuleSetInfoTable OBJECT-TYPE
SYNTAX SEQUENCE OF FlowRuleSetInfoEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"An array of information about the RuleSets held in the
meter.
Any manager may configure a new RuleSet for the meter by
creating a row in this table with status active(1), and setting
values for all the objects in its rules. 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."

DESCRIPTION
"Time this row's associated RuleSet was last changed."
::= { 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."

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."

"The parameter N for statistical counting on this interface.
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

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,

flowManagerInfoEntry OBJECT-TYPE
SYNTAX FlowManagerInfoEntry
MAX-ACCESS not-accessible

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)."

-- TimeMark variable together with successive GetBulk requests to
-- retrieve the values of the desired flow attribute variables.
-- This scheme allows multiple meter readers to independently use the
-- same meter; the meter readers do not have to be synchronised and
-- they may use different collection intervals.
-- If identical sets of counts are required from a meter, a manager
-- could achieve this using two identical copies of a RuleSet in that
