NetFlow Services Card
The NetFlow Services Card supports statistics capture in hardware for flow-based and VLAN-based statistics monitoring. NetFlow services capture and cache detailed information about each data flow (a stream of Packets traveling in one direction from one endpoint to another across the network). Data in the NetFlow cache includes information with regards to specific flows including details such as IP addresses, packet and byte counts, timestamps, and application ports. This data can be exported, collected, and analyzed for a variety of purposes.
