I used the analyzer in both pass-through and end-station setups on a network built primarily with Cisco hardware. My end users had freedom to do whatever they chose on the network, including creating their own problems. In every session, I instantly identified those conditions that caused network slowdowns--such as dozens of machines on one subnet trying to make a high number of DNS calls to a nonexistent server. And it took mere seconds to filter a port used by one of the recent attacks to find machines that were still spewing worm-related traffic.
