channelIndex OBJECT-TYPE
SYNTAX INTEGER (1..65535)
ACCESS read-only
STATUS mandatory
DESCRIPTION
"An index that uniquely identifies an entry
in the channel table. Each such
entry defines one channel, a logical data
and event stream."
::= { channelEntry 1 }
channelIfIndex OBJECT-TYPE
SYNTAX INTEGER (1..65535)
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The value of this object uniquely identifies the
interface on this remote network monitoring device
to which the associated filters are applied to allow
data into this channel. The interface identified by
a particular value of this object is the same
interface as identified by the same value of the
ifIndex object, defined in [4,6]. The filters in
this group are applied to all packets on the local
network segment attached to the identified
interface.
This object may not be modified if the associated
channelStatus object is equal to valid(1)."
::= { channelEntry 2 }
channelAcceptType OBJECT-TYPE
SYNTAX INTEGER {
acceptMatched(1),
acceptFailed(2)
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"This object controls the action of the filters
associated with this channel. If this object is equal
to acceptMatched(1), packets will be accepted to this
channel if they are accepted by both the packet data
and packet status matches of an associated filter. If
this object is equal to acceptFailed(2), packets will
be accepted to this channel only if they fail either
the packet data match or the packet status match of
each of the associated filters.
This object may not be modified if the associated
channelStatus object is equal to valid(1)."
::= { channelEntry 3 }
channelDataControl OBJECT-TYPE
SYNTAX INTEGER {
on(1),
off(2)
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"This object controls the flow of data through this
channel. If this object is on(1), data, status and
events flow through this channel. If this object is
off(2), data, status and events will not flow through
this channel."
DEFVAL { off }
::= { channelEntry 4 }
channelTurnOnEventIndex OBJECT-TYPE
SYNTAX INTEGER (0..65535)
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The value of this object identifies the event
that is configured to turn the associated
channelDataControl from off to on when the event is
generated. The event identified by a particular value
of this object is the same event as identified by the
same value of the eventIndex object. If there is no
corresponding entry in the eventTable, then no
association exists. In fact, if no event is intended
for this channel, channelTurnOnEventIndex must be
set to zero, a non-existent event index.
This object may not be modified if the associated
channelStatus object is equal to valid(1)."
::= { channelEntry 5 }
channelTurnOffEventIndex OBJECT-TYPE
SYNTAX INTEGER (0..65535)
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The value of this object identifies the event
that is configured to turn the associated
channelDataControl from on to off when the event is
generated. The event identified by a particular value
of this object is the same event as identified by the
same value of the eventIndex object. If there is no
corresponding entry in the eventTable, then no
association exists. In fact, if no event is intended
for this channel, channelTurnOffEventIndex must be
set to zero, a non-existent event index.
This object may not be modified if the associated
channelStatus object is equal to valid(1)."
::= { channelEntry 6 }
channelEventIndex OBJECT-TYPE
SYNTAX INTEGER (0..65535)
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The value of this object identifies the event
that is configured to be generated when the
associated channelDataControl is on and a packet
is matched. The event identified by a particular value
of this object is the same event as identified by the
same value of the eventIndex object. If there is no
corresponding entry in the eventTable, then no
association exists. In fact, if no event is intended
for this channel, channelEventIndex must be
set to zero, a non-existent event index.
This object may not be modified if the associated
channelStatus object is equal to valid(1)."
::= { channelEntry 7 }
channelEventStatus OBJECT-TYPE
SYNTAX INTEGER {
eventReady(1),
eventFired(2),
eventAlwaysReady(3)
}
ACCESS read-write
STATUS mandatory
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
flow control and allow events to be generated
at will, this object may be set to
eventAlwaysReady(3). Disabling the flow control
is discouraged as it can result in high network
traffic or other performance problems."
DEFVAL { eventReady }
::= { channelEntry 8 }

::= { channelEntry 12 }
-- The Packet Capture Group
-- Implementation of the Packet Capture group is optional.
--
-- The Packet Capture Group requires implementation of the
-- Filter Group.
--
-- The Packet Capture group allows packets to be captured
-- upon a filter match. The bufferControlTable controls
-- the captured packets output from a channel that is
-- associated with it. The captured packets are placed
-- in entries in the captureBufferTable. These entries are
-- associated with the bufferControlEntry on whose behalf they
-- were stored.

SYNTAX SEQUENCE OF BufferControlEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"A list of buffers control entries."
::= { capture 1 }
bufferControlEntry OBJECT-TYPE
SYNTAX BufferControlEntry
ACCESS not-accessible

DESCRIPTION
"A set of parameters that control the collection of
a stream of packets that have matched filters."
INDEX { bufferControlIndex }
::= { bufferControlTable 1 }
BufferControlEntry ::= SEQUENCE {
bufferControlIndex INTEGER (1..65535),
bufferControlChannelIndex INTEGER (1..65535),
bufferControlFullStatus INTEGER,

}
bufferControlIndex OBJECT-TYPE
SYNTAX INTEGER (1..65535)
ACCESS read-only
STATUS mandatory
DESCRIPTION
"An index that uniquely identifies an entry
in the bufferControl table. The value of this
index shall never be zero. Each such
entry defines one set of packets that is
captured and controlled by one or more filters."
::= { bufferControlEntry 1 }
bufferControlChannelIndex OBJECT-TYPE
SYNTAX INTEGER (1..65535)
ACCESS read-write
STATUS mandatory
DESCRIPTION
"An index that identifies the channel that is the
source of packets for this bufferControl table.
The channel identified by a particular value of this
index is the same as identified by the same value of
the channelIndex object.
This object may not be modified if the associated
bufferControlStatus object is equal to valid(1)."
::= { bufferControlEntry 2 }
bufferControlFullStatus OBJECT-TYPE
SYNTAX INTEGER {
spaceAvailable(1),
full(2)
}
ACCESS read-only
STATUS mandatory
DESCRIPTION
"This object shows whether the buffer has room to
accept new packets or if it is full.
If the status is spaceAvailable(1), the buffer is
accepting new packets normally. If the status is
full(2) and the associated bufferControlFullAction
object is wrapWhenFull, the buffer is accepting new
packets by deleting enough of the oldest packets
to make room for new ones as they arrive. Otherwise,
if the status is full(2) and the
bufferControlFullAction object is lockWhenFull,
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
packets to make room for newly arrived packets
must not affect the value of this object."
::= { bufferControlEntry 3 }
bufferControlFullAction OBJECT-TYPE
SYNTAX INTEGER {
lockWhenFull(1),
wrapWhenFull(2) -- FIFO
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"Controls the action of the buffer when it
reaches the full status. When in the lockWhenFull(1)
state a packet is added to the buffer that
fills the buffer, the bufferControlFullStatus will
be set to full(2) and this buffer will stop capturing
packets."
::= { bufferControlEntry 4 }
bufferControlCaptureSliceSize OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The maximum number of octets of each packet
that will be saved in this capture buffer.
For example, if a 1500 octet packet is received by
the probe and this object is set to 500, then only
500 octets of the packet will be stored in the
associated capture buffer. If this variable is set
to 0, the capture buffer will save as many octets
as is possible.
This object may not be modified if the associated
bufferControlStatus object is equal to valid(1)."
DEFVAL { 100 }
::= { bufferControlEntry 5 }
bufferControlDownloadSliceSize OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The maximum number of octets of each packet
in this capture buffer that will be returned in
an SNMP retrieval of that packet. For example,
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."
DEFVAL { 100 }
::= { bufferControlEntry 6 }
bufferControlDownloadOffset OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The offset of the first octet of each packet
in this capture buffer that will be returned in
an SNMP retrieval of that packet. For example,
if 500 octets of a packet have been stored in the
associated capture buffer and this object is set to
100, then the captureBufferPacket object that
contains the packet will contain bytes starting
100 octets into the packet."
DEFVAL { 0 }
::= { bufferControlEntry 7 }
bufferControlMaxOctetsRequested OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The requested maximum number of octets to be
saved in this captureBuffer, including any
implementation-specific overhead. If this variable
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 }
::= { bufferControlEntry 8 }
bufferControlMaxOctetsGranted OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
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."

DESCRIPTION
"An index that describes the order of packets
that are received on a particular interface.
The packetID of a packet captured on an
interface is defined to be greater than the
packetID's of all packets captured previously on
the same interface. As the captureBufferPacketID
object has a maximum positive value of 2^31 - 1,

DESCRIPTION
"A value which indicates the error status of this
packet.
The value of this object is defined in the same way as
filterPacketStatus. The value 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 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
3 First packet in this capture buffer after
it was detected that some packets were
not processed correctly.
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."

-- The Event Group
-- Implementation of the Event group is optional.
--
-- The Event group controls the generation and notification
-- of events from this device. Each entry in the eventTable
-- describes the parameters of the event that can be triggered.
-- Each event entry is fired by an associated condition located
-- elsewhere in the MIB. An event entry may also be associated
-- with a function elsewhere in the MIB that will be executed
-- when the event is generated. For example, a channel may
-- be turned on or off by the firing of an event.
--
-- Each eventEntry may optionally specify that a log entry
-- be created on its behalf whenever the event occurs.
-- Each entry may also specify that notification should
-- occur by way of SNMP trap messages. In this case, the
-- community for the trap message is given in the associated
-- eventCommunity object. The enterprise and specific trap
-- fields of the trap are determined by the condition that
-- triggered the event. Three traps are defined in a companion
-- document: risingAlarm, fallingAlarm, and packetMatch.
-- If the eventTable is triggered by a condition specified
-- elsewhere, the enterprise and specific trap fields
-- must be specified for traps generated for that condition.
