A network tap is a transmit-only hardware device, placed inline, that provides a permanent access port for passive network monitoring. When a PacketShaper is connected to a tap, it receives the same traffic as if it were located directly on the wire.
The PacketShaper’s INSIDE and OUTSIDE ports are connected to the tap — and watch mode is not enabled. The tap will copy traffic in both inbound and outbound directions.
Since the tap does not pass traffic back to the network, you must use the MGMT port (on PacketShaper 1700, 3500, 7500, and 12000 models) to manage the unit.
