Product Overview

Today’s high-performance data centers need a highly scalable, cost-effective architecture for cross-device flow generation. The Cisco® NGA 3340 generates, unifies, and exports flow data. Network operations, engineering, and security teams are thus empowered to boost network operations excellence. Enhance services delivery. Implement accurate billing. And harden network security. Figure 1 shows the appliance.

Features and Benefits

Built on best-in-class Cisco Unified Computing System (Cisco UCS®) C220 M4 Rack Server hardware, the Cisco NetFlow Generation Appliance (NGA) enables flow visibility in high-throughput Gigabit Ethernet networks typical of most data centers and campus core deployments. Simplifying operational manageability, the appliances can be deployed at key observation points such as the server access layer, fabric path domains, and Internet exchange points. Visibility is dramatically amplified when NGA is connected to multiple network devices, allowing Layer 2 and Layer 3 flows to be analyzed 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 the Cisco Nexus® 9000, Nexus 7000, Nexus 6000, Nexus 5000, and Nexus 3000 Switches, Cisco Catalyst® 6500 Series Switches using Switched Port Analyzer (SPAN), and network taps. It implements a large active flow cache (80 million) and can be configured to export NetFlow records (Version 5 [v5], Version 9 [v9], and IPFIX) to multiple collectors concurrently to provide a single source of flow visibility for business-critical management applications such as security, billing, capacity planning, and more. Cisco NGA can export NetFlow records in weighted round-robin fashion to achieve load balancing or flow replication across collectors. It also offers up to 10 filters per destination, permitting customization of the exports to address specific management needs (Figure 2).

Table 1 lists the key features and benefits of Cisco NGA.

Table 1.       Features and Benefits



Purpose-built appliance

  Meet the rigorous performance demands of high-speed data centers.
  Achieve 100-percent accuracy with full visibility into traffic flows.

NetFlow v5, v9, and IPFIX export formats

  Preserve investments in your existing NetFlow collection infrastructure.

SPAN and network tap support

  Integrate transparently with flexible setup and configuration options, and without affecting the existing infrastructure.
  Focus on the specific traffic of interest using the rich SPAN configuration option.
  Connect to multiple devices to unify flow visibility and allow hop-by-hop analysis.
  Streamline flow collection with a single source of flow visibility for multiple management applications such as security, billing, capacity planning, network monitoring, and more.
  Customize the exports to address specific management needs; for example, a security application would require 100-percent flow visibility, whereas a billing application would be interested in specific application traffic terminating on select endpoints.
  This effective deployment design maximizes collection scalability.

Advanced filters for custom exports

Load balancing and flow replication across multiple collectors (up to six)

Layer 2 and Layer 3 NetFlow support

  Create a comprehensive view of traffic flows in the data center.

Up to 80 million active flow cache entries

  Mitigate the risk of compromising accuracy when the cache becomes full.
  Scale to a variety of traffic profiles with a mix of short- and long-lived flows.

Interface support with managed device

  Extract interface information, namely ifName, ifDescr, ifAlias, ifType, ifMtu, ifSpeed, and ifHighSpeed, and make it available for the NetFlow collectors.

TCP flag export

  Enhance security auditing and detection of security threats with inclusion of TCP flags in the exported flow records. The included TCP flags are those observed since the last export (based on timeout interval) for the same flow.

TCP session timeout based on FIN packet

  Learn about the closing of the TCP session instantly with TCP flow expiry from the cache based on FIN packet detection.

Application awareness

  Recognize application flows on the basis of port, port ranges, and built-in heuristics.

Embedded GUI and command-line interface (CLI) for

  Configure the product quickly with an easy-to-use GUI.

Trusted Platform Module (TPM)

  Securely store artifacts used to authenticate the platform. These artifacts can include passwords, certificates, or encryption keys.
  Store platform measurements that help ensure that the platform remains trustworthy, helping ensure authentication and authorization.


Cisco Integrated Management Controller (IMC) is a built-in management service available with the Cisco NGA 3340. It innovatively differentiates the solution by providing simplified management using a web-based GUI to access, configure, administer, and monitor the NGA. Some of the IMC functions include:

   Power on, power off, power cycle, reset, and shut down the NGA.

   Toggle the locator LED to locate the NGA with a blinking blue LED in the lab.

   Remotely manage the NGA using the keyboard, video, and mouse (KVM) console. The console is an interface accessible from IMC and emulates a direct KVM connection to the NGA. The KVM console allows you to connect to the NGA from a remote location. It also provides the Virtual Media feature that is used for recovery and ISO install.

Platform Support and Compatibility

You can deploy Cisco NGA 3340 with any Cisco network device that you can configure as a SPAN data source. The “managed device” feature is supported with platforms indicated in Table 2.
