This document includes the following sections:
New Features in Cisco NGA
Cisco NetFlow Generation Appliance (NGA) provides network visibility and establishes a new standard for high-performance, cost-effective solutions for flow visibility. It empowers network operations, engineering, and security teams with actionable insight into network traffic for the purpose of resource optimization, application performance improvement, traffic accounting, and security needs.
Cisco NGA 3140 is preinstalled with the Cisco NetFlow Generation Appliance Software Release 1.0 (1). Features include:
•Purpose-built, high-performance form factor.
•SPAN and network tap support
•Load balancing and flow replication across multiple collectors
•Support for up to six collectors
•Advanced filters for custom exports
•Enhanced application recognition and reporting on the basis of port, port-ranges, and built-in heuristics
•Embedded GUI and command-line interface (CLI) for configuration
•NetFlow v5, v9, and IPFIX support
•Interface visibility using supported managed devices to populate NetFlow interface fields
For detailed feature descriptions see the "Overview" in the User Guide for Cisco NetFlow Generation Appliance.
Note This software is preinstalled on a UCS C-Series server. Where applicable, documentation may reference the UCS C-Series guides for hardware-specific tasks such as rack mounting and technical specifications. Because Cisco NGA is the only application running on this appliance, it does not require you to perform any maintenance or configuration tasks that may be associated with the UCS C-Series server. We recommend you do not attempt to open the appliance unless directed by a customer support representative.

Updates for User Guide
Several updates were made to the User Guide for Cisco NetFlow Generation Appliance after the online help was published. To view the latest product information, see the release notes or the latest documentation on Cisco.com.
The following details will be added to the guide during the next release update:
•You must define a NetFlow v9 record counter field or no NetFlow data generates (since there is no data to collect).
•The v9 record name of an existing flow monitor may still be displayed after the particular flow monitor being edited and changed to exported NetFlow v5 type. The workaround is, while in flow monitor editing mode, use the backspace key to delete the Exporter name then un-select the v9 Record Name when this field becomes editable. Reselect the Exporter then save.
•Even though a negative value is allowed in the Application ID field, do not use any negative values.
•We recommend you carefully name your filters and avoid spaces or commas. If you use spaces and commas in the filter name you cannot add multiple filters to existing filters. This occurs when multiple filters are entered as a list but with spaces between the comma and the filter. You may need to retype all the filters if the filter requires any updates. No problems exist if there are no spaces between the comma and the filters.
•Currently NGA only keeps the last core dump file.
•Table 2 lists the ports used by the Cisco NGA for network communication.
