DESCRIPTION
"This MIB module defines the managed objects that support
monitoring of thresholds on interfaces. Configuration and
monitoring of the thresholds is done through threshold
templates that can be assigned to any subset of interfaces on
the network element. More than one threshold template can be
assigned to a given interface.
This MIB module should be used when it is desired to apply a
common set of thresholds to a subset of the available
interfaces. If a threshold is to be applied to only one
interface, then the EVENT-MIB or the RMON-MIB may be used as
simpler alternatives. If a threshold is to be applied to all
available interfaces, then the EVENT-MIB may be used as a
simpler alternative."

CifthTemplateIndex ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"An arbitrary integer that uniquely identifies a threshold
template. The value for each threshold template must remain
constant at least from one re-initialization of the agent's
network management system to the next re-initialization. The
value may change when the agent's network management system is
rebooted or re-initialized."

CifthThresholdList ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A list of thresholds defined in a given template, in which
each bit represents one threshold. The bits in the first octet
represent thresholds identified by cifthThresholdIndex values 0
through 7, inclusive. The bits in the second octet represent
thresholds identified by integer values 8 through 15,
inclusive, and so forth. The least significant bit of an octet
represents the threshold identified by the lowest integer
value, and the most significant bit represents the threshold
identified by the highest integer value. The figure shown
below illustrates the format of a threshold list.

A bit value of '1' indicates that the threshold is being
exceeded in current operation (i.e., the threshold is fired).
A bit value of '0' indicates that the threshold is not being
exceeded in current operation (i.e., the threshold is cleared).
A threshold list of length N, where N < 8, represents a
threshold list for which thresholds N*8 through 63 have the
value of '0'. A special case is a threshold list having a
length of '0', which represents a threshold list of all zeros."

CifthThresholdSeverity ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The severity of the condition when the threshold is fired.
A smaller enumerated integer value indicates that the threshold
exceeded condition is more severe.
The value 'fail' indicates a hard failure condition where
no data can be received, or where the data received has a large
number of errors which makes it impossible to recover most of
the data.
The value 'degrade' indicates a soft failure condition in which
data received on this interface is affected, but a significant
portion of the data can be recovered.
The value 'info' is used to raise attention to a condition that
could possibly be an impending problem or to notify the
customer of an event that improves operation."

no unassigned entries are available.
To obtain a suggested cifthTemplateIndex value for a new entry,
the manager issues a management protocol retrieval operation to

an unused value of cifthTemplateIndex for a new entry.
The agent will modify the value to the next unassigned index,

Once an entry has been activated, the value of
cifthTemplateName cannot be modified. In order to use a new

DESCRIPTION
"This object specifies the method used to prevent an excess of
notifications from being generated when operation fluctuates
around a threshold level.
The value 'holdDownTimer' indicates that notifications for a
given threshold and interface are suppressed for a short amount
of time after each notification. The time value is specified
in cifthTemplateNotifyHoldDownTime, which is instantiated only
when this object is set to 'holdDownTimer'. After a
notification is received for a given threshold and interface,
the next notification for that threshold and interface will be
generated after at least cifthTemplateNotifyHoldDownTime amount
of time has passed, only when the threshold is next fired or
cleared.
The value 'fireAndClearThresholds' indicates that hysteresis
is used. The management client configures two values for each
threshold: one for asserting that the threshold has been
exceeded (see cifthThresholdFiredValue), and a second value for
asserting that the threshold is no longer being exceeded (see
cifthThresholdClearedValue, which is instantiated only when
this object is set to 'fireAndClearThresholds').
When this entry in cifthTemplateTable is active, this object
may only be modified if there are no active entries in
cifthThresholdTable with the same value of cifthTemplateIndex."

SYNTAX INTEGER {

}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The manner in which to compare cifthThresholdObject to
cifthThresholdFiredValue and cifthThresholdClearedValue.
The value 'absoluteValue' indicates that the value of
cifthThresholdObject is to be compared directly to
cifthThresholdFiredValue or cifthThresholdClearedValue.
The value 'deltaValue' indicates that the difference between
two successive samples of cifthThresholdObject is to be
compared to cifthThresholdFiredValue or
cifthThresholdClearedValue. The polling interval between
successive samples is defined in cifthThresholdSampleInterval.
The value 'rateOfIncreaseExponentXIfSpeed' indicates that the
rate of increase of cifthThresholdObject is to be compared to
the negated value of cifthThresholdFiredValue used as the
exponent of 10, times the value of ifSpeed (if the value of
ifSpeed is less than the maximum value) or ifHighSpeed
(otherwise). For example, a value of cifthThresholdFiredValue
of 5 on a gigabit ethernet interface indicates a threshold of
10^-5 times the interface speed, which is equal to 10,000 per
second. When the value of this object is
'rateOfIncreaseExponentXIfSpeed', the polling interval between
successive samples is determined automatically by the agent.
When the object identified by cifthThresholdObject is a
counter, a threshold type of 'deltaValue' or
'rateOfIncreaseExponentXIfSpeed' should be used. When the
object identified by cifthThresholdObject is not a counter, a
threshold type of 'absoluteValue' should be used."

The value 'rising' indicates that the threshold is fired when
the current sampled value is numerically greater than or equal
to the value of cifthThresholdFiredValue, and the threshold was
considered to be cleared at the last sampling interval. If the
value of the corresponding cifthTemplateNotifyHoldDownType
object is 'fireAndClearThresholds', the threshold is cleared
when the current sampled value is less than the value of
cifthThresholdClearedValue, and the threshold was considered to
be fired at the last sampling interval. If the value of the
corresponding cifthTemplateNotifyHoldDownType object is other
than 'fireAndClearThresholds', the threshold is cleared when
the current sampled value is less than the value of
cifthThresholdFiredValue, and the threshold was considered to
be fired at the last sampling interval.
The value 'falling' indicates that the threshold is fired when
the current sampled value is numerically less than or equal to
the value of cifthThresholdFiredValue, and the threshold was
considered to be cleared at the last sampling interval. If the
value of the corresponding cifthTemplateNotifyHoldDownType
object is 'fireAndClearThresholds', the threshold is cleared
when the current sampled value is greater than the value of

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'."

defined on an object that does not have an instance for this
interface, then the threshold is not activated on this
interface.
When an entry is destroyed, all thresholds in the template are
de-activated on this interface and the corresponding entry in
the cifthIfThresholdFiredTable is deleted, if it exists.
After the entry has been activated, this object cannot be set
to any value other than 'destroy'. The row status never
changes to 'notInService' after reaching the value 'active'."

DESCRIPTION
"This object specifies the minimum severity threshold governing
the generation of cifthIfThresholdFired and
cifthIfThresholdCleared notifications. For example, if the
value of this object is set to 'degrade', then the agent
generates these notifications if and only if the severity of
the threshold being exceeded is 'degrade' or 'fail'. When the
value is other than '0', the generation of
cifthTemplateIfStatusChange notifications is also enabled. The
value of '0' disables the generation of all notifications. By
default, the value of this object is set to '0'."

when the value of cifthTemplateIfAssignOperStatus changes. If
a template becomes operationally down on an interface upon
activation of a new entry in the cifthTemplateIfAssignTable,
the agent generates this notification. The agent need not
generate this notification when a new entry in the
cifthTemplateIfAssignTable is activated, if the template
becomes operational on the interface. The agent need not
generate this notification when an entry in the
