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.
