CISCO-IP-TAP-MIB Table View

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 row .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.
