Overview This section provides an introduction to the Cisco NetFlow Generation Appliance and describes the appliance hardware and major components. The Cisco NetFlow Generation Appliance 3340 comes preloaded with Cisco NetFlow Generation 1.1 (1) software. The software generates NetFlow records where native NetFlow generation capability is missing or is limited due to performance impact to your switches.
You can direct packets to the Cisco NetFlow Generation Appliance using either or both of the following methods: • A Switched Port Analyzer (SPAN) session (also known as port mirroring) from the Cisco Nexus or Catalyst device to Cisco NGA using the Nexus supervisor command line interface. Port mirroring selects network traffic for analysis by a network analyzer. • A network tap. A network tap is a hardware device which provides a copy of the data that flows across a network link. See your router or switch device documentation for details on how to set up these monitoring configurations.The SPAN function or a hardware network tap from any Ethernet link can support multiple network devices.
The appliance includes an embedded, web-based GUI that provides quick access to the configuration menus and presents easy-to-access administrative information about your appliance.
