citapStreamCapabilities 1.3.6.1.4.1.9.9.394.1.1.1
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 cTap2StreamInterceptEnable 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.

citapStreamTable 1.3.6.1.4.1.9.9.394.1.1.2
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 cTap2StreamTable. Entries are added to this table via citapStreamStatus in accordance with the RowStatus convention.

    CitapStreamEntry

citapStreamEntry 1.3.6.1.4.1.9.9.394.1.1.2.1
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.
Status: mandatory Access: not-accessible
OBJECT-TYPE    
  CitapStreamEntry  

citapStreamInterface 1.3.6.1.4.1.9.9.394.1.1.2.1.1
The ifIndex value of the interface over which traffic to be intercepted is received or transmitted. The interface may be 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 citapStreamDestinationAddress and citapStreamSourceAddress 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 citapStreamSourceAddress, citapStreamSourceLen and citapStreamSourceL4PortMin 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.
