| Description | This object indicates whether the threshold template
identified by cifthTemplateIndex is operational on the
interface identified by cifthTemplateIfAssignInterface.
When the value of this object is 'up', this indicates that
the thresholds in this template (identified by
cifthTemplateIndex) are activated on this interface, with the
following exception: If a threshold is defined on an object
that does not have an instance for this interface, then the
threshold is not activated on this interface. If any of the
thresholds are being exceeded, then a corresponding entry
exists in the cifthIfThresholdFiredTable.
When the value of this object is 'down', this indicates that
all thresholds in the template are de-activated on this
interface and there is no corresponding entry in the
cifthIfThresholdFiredTable, regardless of whether any of the
thresholds in the template are being exceeded on this
interface.
One reason for a template not to be operational on an
interface to which it is assigned is when the interface has two
(or more) templates assigned to it that contain thresholds on
the same object with the same severity and direction, i.e.,
thresholds with the same values of cifthThresholdObject,
cifthThresholdSeverity, and cifthThresholdDirection. This may
occur when a template is assigned to the interface, or when a
threshold is added to a template that is already active on the
interface. When this occurs, the implementation may operate on
both (or all) threshold values, or it may take down one (or
more) of the templates on this interface, which is indicated by
changing the value of this object from 'up' to 'down'. |
