DESCRIPTION
|
|
"A MIB module containing textual conventions
|
|
for high capacity data types. This module
|
|
addresses an immediate need for data types not directly
|
|
supported in the SMIv2. This short-term solution
|
|
is meant to be deprecated as a long-term solution
|
|
is deployed."
|
|
REVISION "200006080000Z"
|
|
DESCRIPTION
|
|
"Initial Version of the High Capacity Numbers
|
|
MIB module, published as RFC 2856."
|
|
::= { mib-2 78 }
|
|
|
|
CounterBasedGauge64 ::= TEXTUAL-CONVENTION
|
|
STATUS current
|
|
DESCRIPTION
|
|
"The CounterBasedGauge64 type represents a non-negative
|
|
integer, which may increase or decrease, but shall never
|
|
exceed a maximum value, nor fall below a minimum value. The
|
|
maximum value can not be greater than 2^64-1
|
|
(18446744073709551615 decimal), and the minimum value can
|
|
|
|
not be smaller than 0. The value of a CounterBasedGauge64
|
|
has its maximum value whenever the information being modeled
|
|
is greater than or equal to its maximum value, and has its
|
|
minimum value whenever the information being modeled is
|
|
smaller than or equal to its minimum value. If the
|
|
information being modeled subsequently decreases below
|
|
(increases above) the maximum (minimum) value, the
|
|
CounterBasedGauge64 also decreases (increases).
|
|
|
|
Note that this TC is not strictly supported in SMIv2,
|
|
because the 'always increasing' and 'counter wrap' semantics
|
|
associated with the Counter64 base type are not preserved.
|
|
It is possible that management applications which rely
|
|
solely upon the (Counter64) ASN.1 tag to determine object
|
|
semantics will mistakenly operate upon objects of this type
|
|
as they would for Counter64 objects.
|
|
|
|
This textual convention represents a limited and short-term
|
|
solution, and may be deprecated as a long term solution is
|
|
defined and deployed to replace it."

ZeroBasedCounter64 ::= TEXTUAL-CONVENTION

STATUS current
|
|
DESCRIPTION
|
|
"This TC describes an object which counts events with the
|
|
following semantics: objects of this type will be set to
|
|
zero(0) on creation and will thereafter count appropriate
|
|
events, wrapping back to zero(0) when the value 2^64 is
|
|
reached.
|
|
|
|
Provided that an application discovers the new object within
|
|
the minimum time to wrap it can use the initial value as a
|
|
delta since it last polled the table of which this object is
|
|
part. It is important for a management station to be aware
|
|
of this minimum time and the actual time between polls, and
|
|
to discard data if the actual time is too long or there is
|
|
no defined minimum time.
|
|
|
|
Typically this TC is used in tables where the INDEX space is
|
|
constantly changing and/or the TimeFilter mechanism is in
|
|
use.
|
|
|
|
Note that this textual convention does not retain all the
|
|
semantics of the Counter64 base type. Specifically, a
|
|
Counter64 has an arbitrary initial value, but objects
|
|
defined with this TC are required to start at the value
|
|
|
|
zero. This behavior is not likely to have any adverse
|
|
effects on management applications which are expecting
|
|
Counter64 semantics.
|
|
|
|
This textual convention represents a limited and short-term
|
|
solution, and may be deprecated as a long term solution is
|
|
defined and deployed to replace it."
