SteelCentral for Packet Collection
SteelCentral collects packets using one of the following devices:
•  NetShark
•  NetExpress 470 with built-in NetShark capability
•  AppResponse with NetShark
•  SteelHead EX with NetShark-v
•  NetShark-v
All the above devices capture packets at up to line rate, write those packets to disk, perform analysis on those packets, allow easy retrieval of stored packets, and forward packets to capture devices.
You can forward flows from these devices to the NetProfiler based upon the packets that the appliance collects. In addition to standard NetFlow-type fields, these components send TCP health, performance, and end-user experience information. For more information about these components, see SteelCentral NPM Overview and SteelCentral NPM Deployment Scenarios.
