"This tool acts much like a standard Ethernet network sniffer. However, unlike a traditional packet sniffer it doesn't attempt to capture and decode all traffic but instead is geared toward discovering useful infrastructure and security-related data from the network, often from traffic not sent to or from the host system i.e. general broadcast network traffic"

I dont think it give you much control over what you can sniff mind. I havent used it, but thats the general impression I get from readin about it.
