When monitoring a SPAN or hub port, Sensors with internal taps are disabled.
In the following figure showing an NS9500 base Sensor model, Port G0/1 receives data from the SPAN port of SwitchA. Port G0/2 gets data from the SPAN port of SwitchB. Two distinct network links from two separate switches are monitored by the one active NS9500 Sensor with a 5 Gbps rate per link to the Sensor, allowing a total of 10 Gbps traffic to the IPS engine.
