| 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). |
