Breakout mode

V-Line Module Breakout mode (see the figure below) sends copies of traffic from the live network A and B ports to a
selectable combination of C and D ports with or without optional packet slicing. Packets received on the live network
ports (A, B) can be passed to other modules in the system. Filters are not supported on maps from the V-Line module to
other modules in the system
