Sensors are equipped with multiple Monitoring and Response ports. By default, the Sensor ports are internally wire matched to monitor traffic in full-duplex pairs, that is, two detection ports work together to monitor traffic flowing in both directions.
To monitor a full-duplex segment in In-line or Tap mode, you use two Sensor ports (one port for transmit, one for receive). SPAN port monitoring receives on one port and can respond via the same port (if the switch supports this feature).
NS-series Sensor model | Supported number of full-duplex links | Supported number of half-duplex links |
|---|---|---|
NS9600 | 4 | 0 |
NS9500 | 6 | 4 |
NS9300 | 20 | 16 |
NS9200 | 10 | 8 |
NS9100 | 10 | 8 |
NS7600 | 4 | 0 |
NS7x50 | 10 | 8 |
NS7x00 | 10 | 8 |
NS5x00 | 22 | 20 |
NS3600 | 8 | 8 |
NS3500 | 4 | 4 |
NS3x00 | 8 | 8 |
In-line mode and tap mode can both monitor full-duplex links.
SPAN monitoring works in either half- or full-duplex mode (depending on the switch).
Hub monitoring works in half-duplex mode.
