| pktcESIpTapMIB |
1.3.6.1.4.1.4491.2.2.9.1.2 |
| This module manages intercept feature for IP.
This MIB is used along with TAP-MIB to
intercept IP traffic. TAP-MIB along with
specific filter MIBs like this MIB replace
TAP-MIB.
To create an IP intercept, an entry pktcESTapStreamEntry
is created which contains the filter details. An entry
pktcEScpktcESTapStreamEntry of TAP-MIB is created, which
is the common stream information for all kinds of
intercepts and type of the specific stream is set to
ip in this entry. |

1.3.6.1.4.1.4491.2.2.9.1.2.1.1.1 |
| 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:
tapEnable: set if table entries with
pktcEScTapStreamInterceptEnable set to
'false'
are used to pre-screen packets for intercept;
otherwise these entries are ignored.
interface: SNMP ifIndex Value may be used to select
interception of all data crossing an
interface or set of interfaces.
ipV4: IPv4 Address or prefix may be used to select
traffic to be intercepted.
ipV6: IPv6 Address or prefix may be used to select
traffic to be intercepted.
l4Port: TCP/UDP Ports may be used to select traffic
to be intercepted.
dscp: DSCP (Differentiated Services Code Point) may
be used to select traffic to be intercepted.
voip: packets belonging to a voice session may
be intercepted using source IPv4 address and
source UDP port. |

| pktcESTapStreamTable |
1.3.6.1.4.1.4491.2.2.9.1.2.1.1.2 |
| 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 value of the
second index is that of the stream's counter entry in the
pktcEScTapStreamTable.
Entries are added to this table via pktcESTapStreamStatus in
accordance with the RowStatus convention. |

| pktcESTapStreamEntry |
1.3.6.1.4.1.4491.2.2.9.1.2.1.1.2.1 |
| 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. |

1.3.6.1.4.1.4491.2.2.9.1.2.1.1.2.1.1 |
| The ifIndex value of the interface over which traffic to be
intercepted is received or transmitted. The interface may be
PKT-SP-ES-INF-I02-061013 PacketCableTM 2.0

physical or virtual. If this is the only parameter specified,
and it is other than -2, -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
pktcESTapStreamDestinationAddress and
pktcESTapStreamSourceAddress 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.
If the value is -2, packets belonging to a Voice over IP (VoIP)
session identified by pktcESTapStreamSourceAddress,
pktcESTapStreamSourceLen & pktcESTapStreamSourceL4PortMin may be
intercepted, as a specific voice session can be identified
with source IP address and udp port number. Other selection
parameters may be not considered, even if they are set by
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. |
