column r/w Integer32

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.
