I have a stupid question to ask. We are about to deploy a number of IPS42xx appliances. There's no free ports on the switches to connect their sensing interfaces to the switch SPAN port. Is there any way to use a pair of the sensor's interfaces to send traffic through the sensor but the sensor itself should be running in IDS (monitoring) mode. The client might opt to switch to real IPS (inline) mode after they tune their signatures. And it should be just changing the settings on the sensor not reconnecting cables.
