Cisco NetFlow Generation Appliance (NGA) 3140
Product Overview
The Cisco
®
NetFlow Generation Appliance (NGA) 3140 (Figure 1) redefines 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.

The product introduces a cross-device approach to NetFlow analysis, facilitating correlated hop-by-hop flow
visibility. Providing granular, end-to-end visibility into the network, it allows you to significantly improve operational
efficiency and effectively reinforce network security.
Features and Benefits
Cisco NGA is a purpose-built, high-performance solution for flow visibility in high throughput Gigabit Ethernet
networks typical in most data centers and campus core deployments. Simplifying operational manageability, the
appliances can be deployed at key observation places such as the server access layer, fabric path domains, and
Internet exchange points. The power of visibility is dramatically amplified when NGA is connected to multiple
network devices to analyze flows hop by hop, essential for security, capacity planning, and troubleshooting.
Designed for high performance and maximum deployment flexibility, the appliance gathers network data from
platforms such as Cisco Nexus

7000, Cisco Nexus 5000, Catalyst
®
6500 Series Switches using Switched Port
Analyzer (SPAN) and network taps. It implements a large active flow cache and can be configured to export
NetFlow records (v5, v9, IPFIX) to multiple collectors. The NetFlow Data Export (NDE) records are exported in
weighted round-robin fashion to achieve load balancing or flow replication across collectors. The exports can also
be customized to meet specific management application needs using 10 filters per destination (Figure 2).
