hostTopNDuration object.
When this object is set to a non-zero value, any
associated hostTopNEntries shall be made
inaccessible by the monitor. While the value of this
object is non-zero, it decrements by one per second
until it reaches zero. During this time, all
associated hostTopNEntries shall remain
inaccessible. At the time that this object
decrements to zero, the report is made

-- The Filter Group
-- Implementation of the Filter group is optional.
--
-- The Filter group allows packets to be captured with an
-- arbitrary filter expression. A logical data and
-- event stream or "channel" is formed by the packets
-- that match the filter expression.
--
-- This filter mechanism allows the creation of an arbitrary
-- logical expression with which to filter packets. Each
-- filter associated with a channel is OR'ed with the others.
-- Within a filter, any bits checked in the data and status are
-- AND'ed with respect to other bits in the same filter. The
-- NotMask also allows for checking for inequality. Finally,
-- the channelAcceptType object allows for inversion of the
-- whole equation.
--
-- The channel can be turned on or off, and can also
-- generate events when packets pass through it.

ACCESS read-write

DESCRIPTION
"The data that is to be matched with the input packet.
For each packet received, this filter and the
accompanying filterPktDataMask and
filterPktDataNotMask will be adjusted for the
offset. The only bits relevant to this
match algorithm are those that have the corresponding
filterPktDataMask bit equal to one. The following
three rules are then applied to every packet:
(1) If the packet is too short and does not have data
corresponding to part of the filterPktData, the
packet will fail this data match.
(2) For each relevant bit from the packet with the
corresponding filterPktDataNotMask bit set to
zero, if the bit from the packet is not equal to
the corresponding bit from the filterPktData,
then the packet will fail this data match.
(3) If for every relevant bit from the packet with the
corresponding filterPktDataNotMask bit set to one,
the bit from the packet is equal to the
corresponding bit from the filterPktData, then
the packet will fail this data match.
Any packets that have not failed any of the three

ACCESS read-write
STATUS mandatory
DESCRIPTION
"The mask that is applied to the match process.
After adjusting this mask for the offset, only those
bits in the received packet that correspond to bits
set in this mask are relevant for further processing
by the match algorithm. The offset is applied to
filterPktDataMask in the same way it is applied to
the filter. For the purposes of the matching
algorithm, if the associated filterPktData object
is longer than this mask, this mask is conceptually
extended with '1' bits until it reaches the
length of the filterPktData object.
This object may not be modified if the associated
filterStatus object is equal to valid(1)."
::= { filterEntry 5 }

SYNTAX OCTET STRING
ACCESS read-write

DESCRIPTION
"The inversion mask that is applied to the match
process. After adjusting this mask for the offset,
those relevant bits in the received packet that
correspond to bits cleared in this mask must all
be equal to their corresponding bits in the
filterPktData object for the packet to be accepted.
In addition, at least one of those relevant
bits in the received packet that correspond to bits
set in this mask must be different to its
corresponding bit in the filterPktData object.
For the purposes of the matching algorithm, if
the associated filterPktData object is longer than
this mask, this mask is conceptually extended with
'0' bits until it reaches the length of the
filterPktData object.
This object may not be modified if the associated
filterStatus object is equal to valid(1)."
::= { filterEntry 6 }
filterPktStatus OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The status that is to be matched with the input
packet. The only bits relevant to this match
algorithm are those that have the corresponding
filterPktStatusMask bit equal to one.
The following two rules are then applied to every
packet:
(1) For each relevant bit from the packet status
with the corresponding filterPktStatusNotMask
bit set to zero, if the bit from the packet
status is not equal to the corresponding bit
from the filterPktStatus, then the packet will
fail this status match.
(2) If for every relevant bit from the packet status
with the corresponding filterPktStatusNotMask
bit set to one, the bit from the packet status
is equal to the corresponding bit from the
filterPktStatus, then the packet will fail
this status match.
Any packets that have not failed either of the two
matches above have passed this status match.
The value of the packet status is a sum. This sum
initially takes the value zero. Then, for each
error, E, that has been discovered in this packet,
2 raised to a value representing E is added to the sum.
The errors and the bits that represent them are
dependent on the media type of the interface that
this channel is receiving packets from.
The errors defined for a packet captured off of an
Ethernet interface are as follows:
bit # Error
0 Packet is longer than 1518 octets
1 Packet is shorter than 64 octets
2 Packet experienced a CRC or Alignment
error
For example, an Ethernet fragment would have a
value of 6 (2^1 + 2^2).
As this MIB is expanded to new media types, this
object will have other media-specific errors defined.
For the purposes of this status matching algorithm, if
the packet status is longer than this
object, filterPktStatus this object is conceptually
extended with '0' bits until it reaches the size of
the packet status.
This object may not be modified if the associated
filterStatus object is equal to valid(1)."

DESCRIPTION
"The mask that is applied to the status match process.
Only those bits in the received packet that correspond

processing by the status match algorithm. For the
purposes of the matching algorithm, if the
associated filterPktStatus object is longer than
this mask, this mask is conceptually extended with
'1' bits until it reaches the size of the
filterPktStatus. In addition, if a packet status is
longer than this mask, this mask is conceptually
extended with '0' bits until it reaches the size of
the packet status.
This object may not be modified if the associated

In addition, at least one of those relevant bits in the

For the purposes of the matching algorithm, if the

DESCRIPTION
"The event status of this channel.
If this channel is configured to generate events
when packets are matched, a means of controlling
the flow of those events is often needed. When
this object is equal to eventReady(1), a single
event may be generated, after which this object
will be set by the probe to eventFired(2). While
in the eventFired(2) state, no events will be
generated until the object is modified to
eventReady(1) (or eventAlwaysReady(3)). The
management station can thus easily respond to a
notification of an event by re-enabling this object.
If the management station wishes to disable this

If the status is spaceAvailable(1), the buffer is
accepting new packets normally. If the status is
full(2) and the associated bufferControlFullAction

then the buffer has stopped collecting packets.
When this object is set to full(2) the probe must
not later set it to spaceAvailable(1) except in the
case of a significant gain in resources such as
an increase of bufferControlOctetsGranted. In
particular, the wrap-mode action of deleting old

if 500 octets of a packet have been stored in the
associated capture buffer, the associated
bufferControlDownloadOffset is 0, and this
object is set to 100, then the captureBufferPacket
object that contains the packet will contain only
the first 100 octets of the packet.
A prudent manager will take into account possible
interoperability or fragmentation problems that may
occur if the download slice size is set too large.
In particular, conformant SNMP implementations are not
required to accept messages whose length exceeds 484
octets, although they are encouraged to support larger
datagrams whenever feasible."

is set to -1, the capture buffer will save as many
octets as is possible.
When this object is created or modified, the probe
should set bufferControlMaxOctetsGranted as closely
to this object as is possible for the particular probe
implementation and available resources. However, if
the object has the special value of -1, the probe
must set bufferControlMaxOctetsGranted to -1."
DEFVAL { -1 }

bufferControlMaxOctetsGranted OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only

DESCRIPTION
"The maximum number of octets that can be
saved in this captureBuffer, including overhead.
If this variable is -1, the capture buffer will save
as many octets as possible.
When the bufferControlMaxOctetsRequested object is
created or modified, the probe should set this object
as closely to the requested value as is possible for
the particular probe implementation and available
resources. However, if the request object has the
special value of -1, the probe must set this object
to -1. The probe must not lower this value except
as a result of a modification to the associated
bufferControlMaxOctetsRequested object.
When this maximum number of octets is reached
and a new packet is to be added to this
capture buffer and the corresponding
bufferControlFullAction is set to wrapWhenFull(2),
enough of the oldest packets associated with this
capture buffer shall be deleted by the agent so
that the new packet can be added. If the
corresponding bufferControlFullAction is set to
lockWhenFull(1), the new packet shall be discarded.
In either case, the probe must set
bufferControlFullStatus to full(2).
When the value of this object changes to a value less
than the current value, entries are deleted from
the captureBufferTable associated with this
bufferControlEntry. Enough of the
oldest of these captureBufferEntries shall be
deleted by the agent so that the number of octets
used remains less than or equal to the new value of
this object.
When the value of this object changes to a value greater
than the current value, the number of associated
captureBufferEntries may be allowed to grow."
