SNMP MIB Search

This object contains a value which may be used as an index
value for a new cTapMediationEntry. Whenever read, the agent
will change the value to a new non-conflicting value.  This is
to reduce the probability of errors during creation of new
cTapMediationTable entries.

The entry describes a single session maintained with an
application on a Mediation Device.

This object displays the device capabilities with respect to
certain fields in Mediation Device table. This may be dependent
on hardware capabilities, software capabilities.
The following values may be supported:
ipV4SrcInterface:  SNMP ifIndex Value may be used to select
the interface (denoted by
cTapMediationSrcInterface) on the
intercepting device from which to
transmit intercepted data to an IPv4
address Mediation Device.
ipV6SrcInterface:  SNMP ifIndex Value may be used to select
the interface (denoted by
cTapMediationSrcInterface) on the
intercepting device from which to
transmit intercepted data to an IPv6
address Mediation Device.
udp:               UDP may be used as transport protocol
(denoted by cTapMediationTransport) in
transferring intercepted data to the
Mediation Device.
rtcpNack:          RTP with Nack resilience may be used
as transport protocol (denoted by
cTapMediationTransport) in transferring
intercepted data to the Mediation
Device.

(denoted by cTapMediationTransport) in
transferring intercepted data to the
Mediation Device.
sctp:              SCTP may be used as transport protocol
(denoted by cTapMediationTransport) in
transferring intercepted data to the
Mediation Device.

This object displays what types of intercept streams can be
configured on this type of device. This may be dependent on
hardware capabilities, software capabilities. The following
fields may be supported:
interface:   SNMP ifIndex Value may be used to select
interception of all data crossing an
interface or set of interfaces.
tapEnable:   set if table entries with
cTapStreamIpInterceptEnable set to 'false'
are used to pre-screen packets for intercept;
otherwise these entries are ignored.
ipV4:        IPv4 Address or prefix may be used to select
traffic to be intercepted.

A stream entry indicates a single data stream to be
intercepted to a Mediation Device. Many selected data
streams may go to the same application interface, and many
application interfaces are supported.

A list of the debug messages.

cTapMediationContentId is a session identifier, from the
intercept application's perspective, and a content identifier
from the Mediation Device's perspective. The Mediation Device
is responsible for making sure these are unique, although the
SNMP RowStatus row creation process will help by not allowing
it to create conflicting entries. Before creating a new entry,
a value for this variable may be obtained by reading
cTapMediationNewIndex to reduce the probability of a value
collision.

The type of cTapMediationDestAddress.

The IP Address of the Mediation Device's network interface
to which to direct intercepted traffic.

The port number on the Mediation Device's network interface
to which to direct intercepted traffic.

The interface on the intercepting device from which to
transmit intercepted data. If zero, any interface may be used
according to normal IP practice.

The port number on the intercepting device to which the
Mediation Devices directs RTCP Receiver Reports and Nacks.
This object is only relevant when the value of
cTapMediationTransport is 'rtpNack'.
This port is assigned by the intercepting device, rather than
by the Mediation Device or manager application.  The value of
this MIB object has no effect before activating the
cTapMediationEntry.

The Differentiated Services Code Point the intercepting
device applies to the IP packets encapsulating the
intercepted traffic.

If RTP with Ack/Nack resilience is selected as a transport,
the mediation process requires an RTP payload type for data
transmissions, and a second RTP payload type for
retransmissions.  This is the RTP payload type for
transmissions.
This object is only effective when the value of
cTapMediationTransport is 'rtpNack'.

If RTP with Ack/Nack resilience is selected as a transport,
the mediation process requires an RTP payload type for data
transmissions, and a second RTP payload type for
retransmissions.  This is the RTP payload type for
retransmissions.
This object is only effective when the value of
cTapMediationTransport is 'rtpNack'.

The time at which this row and all related Stream Table rows
should be automatically removed, and the intercept function
cease. Since the initiating network manager may be the only
device able to manage a specific intercept or know of its
existence, this acts as a fail-safe for the failure or removal
of the network manager. The object is only effective when the
value of cTapMediationStatus is 'active'.

The protocol used in transferring intercepted data to the
Mediation Device. The following protocols may be supported:
udp:     PacketCable udp format
rtpNack: RTP with Nack resilience
tcp:     TCP with head of line blocking
sctp:    SCTP with head of line blocking 

This variable controls the generation of any notifications or
informs by the MIB agent for this table entry.

The status of this conceptual row. This object is used to
manage creation, modification and deletion of rows in this
table.
cTapMediationTimeout may be modified at any time (even while the
row is active). But when the row is active, the other writable
objects may not be modified without setting its value to
'notInService'.
The entry may not be deleted or deactivated by setting its
value to 'destroy' or 'notInService' if there is any associated
entry in cTapStreamIpTable, or other such tables when such are
defined.

The index of the stream itself.

The ifIndex value of the interface over which traffic to be
intercepted is received or transmitted. The interface may be
physical or virtual. If this is the only parameter specified,
and it is other than -1 or 0, all traffic on the selected
interface will be chosen.
If the value is zero, matching traffic may be received or
transmitted on any interface.  Additional selection parameters
must be selected to limit the scope of traffic intercepted.
This is most useful on non-routing platforms or on intercepts
placed elsewhere than a subscriber interface.
If the value is -1, one or both of
cTapStreamIpDestinationAddress and cTapStreamIpSourceAddress
must be specified with prefix length greater than zero.
Matching traffic on the interface pointed to by ipRouteIfIndex
or ipCidrRouteIfIndex values associated with those values is
intercepted, whichever is specified to be more focused than a
default route.  If routing changes, either by operator action
or by routing protocol events, the interface will change with
it. This is primarily intended for use on subscriber interfaces
and other places where routing is guaranteed to be
symmetrical.
In both of these cases, it is possible to have the same packet
selected for intersection on both its ingress and egress
interface.  Nonetheless, only one instance of the packet is
sent to the Mediation Device.
This value must be set when creating a stream entry, either to
select an interface, to select all interfaces, or to select the
interface that routing chooses. Some platforms may not
implement the entire range of options.

The type of address, used in packet selection.

The Destination address or prefix used in packet selection.
This address will be of the type specified in
cTapStreamIpAddrType.

The length of the Destination Prefix. A value of zero causes
all addresses to match.  This prefix length will be consistent
with the type specified in cTapStreamIpAddrType.

The Source Address used in packet selection. This address will
be of the type specified in cTapStreamIpAddrType.

The length of the Source Prefix. A value of zero causes all
addresses to match. This prefix length will be consistent with
the type specified in cTapStreamIpAddrType.

The value of the TOS byte, when masked with
cTapStreamIpTosByteMask, of traffic to be intercepted.
If cTapStreamIpTosByte & (~cTapStreamIpTosByteMask) != 0,
configuration is rejected.

The value of the TOS byte in an IPv4 or IPv6 header is ANDed
with cTapStreamIpTosByteMask and compared with
cTapStreamIpTosByte.
If the values are equal, the comparison is equal. If the mask
is zero and the TosByte value is zero, the result is to always
accept.

The flow identifier in an IPv6 header. -1 indicates that the
Flow Id is unused.

The IP protocol to match against the IPv4 protocol number or
the IPv6 Next- Header number in the packet. -1 means 'any IP
protocol'.

The minimum value that the layer-4 destination port number in
the packet must have in order to match.  This value must be
equal to or less than the value specified for this entry in
cTapStreamIpDestL4PortMax.
If both cTapStreamIpDestL4PortMin and cTapStreamIpDestL4PortMax
are at their default values, the port number is effectively
unused.

The maximum value that the layer-4 destination port number in
the packet must have in order to match this classifier entry.
This value must be equal to or greater than the value specified
for this entry in cTapStreamIpDestL4PortMin.
If both cTapStreamIpDestL4PortMin and cTapStreamIpDestL4PortMax
are at their default values, the port number is effectively
unused.

The minimum value that the layer-4 destination port number in
the packet must have in order to match.  This value must be
equal to or less than the value specified for this entry in
cTapStreamIpSourceL4PortMax.
If both cTapStreamIpSourceL4PortMin and
cTapStreamIpSourceL4PortMax are at their default values, the
port number is effectively unused.

The maximum value that the layer-4 destination port number in
the packet must have in order to match this classifier entry.
This value must be equal to or greater than the value specified
for this entry in cTapStreamIpSourceL4PortMin.
If both cTapStreamIpSourceL4PortMin and
cTapStreamIpSourceL4PortMax are at their default values, the
port number is effectively unused.

If 'true', the tap should intercept matching traffic.
If 'false', this entry is used to pre-screen packets for
intercept.

The number of packets matching this data stream specification
that have been intercepted.

The number of packets matching this data stream specification
that, having been intercepted, were dropped in the lawful
intercept process.

The status of this conceptual row. This object manages
creation, modification, and deletion of rows in this table.
cTapStreamIpInterceptEnable may be modified any time even the
value of this entry rowStatus object is 'active'.  When other
rows must be changed, cTapStreamIpStatus must be first set to
'notInService'.

The index of the stream itself.

This object displays what attributes must be tested to
identify traffic which requires interception. The packet
matches if all flagged fields match.
interface:     indicates that traffic on the stated
interface is to be intercepted
dstMacAddress: indicates that traffic destined to a
given address should be intercepted
srcMacAddress: indicates that traffic sourced from a
given address should be intercepted
ethernetPid:   indicates that traffic with a stated
Ethernet Protocol Identifier should be
intercepted
dstLlcSap:     indicates that traffic with an certain
802.2 LLC Destination SAP should be
intercepted
srcLlcSap:     indicates that traffic with an certain
802.2 LLC Source SAP should be
intercepted
At least one of the bits has to be set in order to activate an
entry.  If the bit is not on, the corresponding MIB object
value has no effect, and need not be specified when creating
the entry.

The ifIndex value of the interface over which traffic to be
intercepted is received or transmitted. The interface may be
physical or virtual. If this is the only parameter specified,
and it is other than -1 or 0, all traffic on the selected
interface will be chosen.
If the value is zero, matching traffic may be received or
transmitted on any interface.  Additional selection parameters
must be selected to limit the scope of traffic intercepted.
This is most useful on non-routing platforms or on intercepts
placed elsewhere than a subscriber interface.
If the value is -1, one or both of
cTapStream802DestinationAddress and cTapStream802SourceAddress
must be specified.  Matching traffic on the interface pointed
to by the dot1dTpFdbPort values associated with those values is
intercepted, whichever is specified.  If dot1dTpFdbPort
changes, either by operator action or by protocol events, the
interface will change with it. This is primarily intended for
use on subscriber interfaces and other places where routing is
guaranteed to be symmetrical.
In both of these cases, it is possible to have the same packet
selected for intersection on both its ingress and egress
interface.  Nonetheless, only one instance of the packet is
sent to the Mediation Device.
This value must be set when creating a stream entry, either to
select an interface, to select all interfaces, or to select the
interface that bridging learns. Some platforms may not
implement the entire range of options.

The Destination address used in packet selection.

The Source Address used in packet selection.

The value of the Ethernet Protocol Identifier, which may be
found on Ethernet traffic or IEEE 802.2 SNAP traffic.

The value of the IEEE 802.2 Destination SAP.

The value of the IEEE 802.2 Source SAP.

If 'true', the tap enables interception of matching traffic.
If cTapStreamCapabilities flag tapEnable is zero, this may not
be set to 'false'.

The number of packets matching this data stream specification
that have been intercepted.

The number of packets matching this data stream specification
that, having been intercepted, were dropped in the lawful
intercept process.

The status of this conceptual row. This object manages
creation, modification, and deletion of rows in this table.
cTapStream802InterceptEnable can be modified any time even the
value of this entry rowStatus object is active.  When other
rows must be changed, cTapStream802Status must be first set to
'notInService'.

Indicates an error code.

A text string contains the description of an error code.

This table lists the Mediation Devices with which the
intercepting device communicates. These may be on the same or
different Mediation Devices.
This table is written by the Mediation Device, and is always
volatile. This is because intercepts may disappear during a
restart of the intercepting equipment.

The Intercept Stream IP Table lists the IPv4 and IPv6 streams
to be intercepted.  The same data stream may be required by
multiple taps, and one might assume that often the intercepted
stream is a small subset of the traffic that could be
intercepted.
This essentially provides options for packet selection, only
some of which might be used. For example, if all traffic to or
from a given interface is to be intercepted, one would
configure an entry which lists the interface, and wild-card
everything else.  If all traffic to or from a given IP Address
is to be intercepted, one would configure two such entries
listing the IP Address as source and destination respectively,
and wild-card everything else.  If a particular voice on a
teleconference is to be intercepted, on the other hand, one
would extract the multicast (destination) IP address, the
source IP Address, the protocol (UDP), and the source and
destination ports from the call control exchange and list all
necessary information.
The first index indicates which Mediation Device the
intercepted traffic will be diverted to. The second index
permits multiple classifiers to be used together, such as
having an IP address as source or destination. 

The Intercept Stream 802 Table lists the IEEE 802 data streams
to be intercepted.  The same data stream may be required by
multiple taps, and one might assume that often the intercepted
stream is a small subset of the traffic that could be
intercepted.
This essentially provides options for packet selection, only
some of which might be used. For example, if all traffic to or
from a given interface is to be intercepted, one would
configure an entry which lists the interface, and wild-card
everything else.  If all traffic to or from a given MAC Address
is to be intercepted, one would configure two such entries
listing the MAC Address as source and destination respectively,
and wild-card everything else.
The first index indicates which Mediation Device the
intercepted traffic will be diverted to. The second index
permits multiple classifiers to be used together, such as
having a MAC address as source or destination. 

A table that contains Lawful Intercept debug information
available on this device. This table is used to map an error
code to a text message for further information.

This Notification is sent when an intercepting router or
switch is first capable of intercepting a packet corresponding
to a configured data stream. If the configured data stream is
an IP one, the value of the corresponding cTapStreamIpStatus
is included in this notification. If the configured data stream
is an IEEE 802 one, the value of the corresponding
cTapStream802Status is included in this notification.
This notification may be generated in conjunction with the
intercept application, which is designed to expect the
notification to be sent as reliably as possible, e.g., through
the use of a finite number of retransmissions until
acknowledged, as and when such mechanisms are available; for
example, with SNMPv3, this would be an InformRequest.  Filter
installation can take a long period of time, during which call
progress may be delayed.

When an intercept is autonomously removed by an intercepting
device, such as due to the time specified in
cTapMediationTimeout arriving, the device notifies the manager
of the action.

When there is intervention needed due to some events related
to entries configured in cTapMediationTable, the device
notifies the manager of the event.
