, we will see how to use the Catalyst function to meet these needs! Detects suspicious traffic Cat6500 and Catalyst 4500 (Sup IV, Sup V and Sup V-10 GE). It provides a hardware-based Netflow function to collect traffic information flowing through the network. The information collection and statistics are completed through the hardware ASCI, so there is no impact on the system performance. The Catalyst 4500
