Product Overview

The Cisco ® NetFlow Generation Appliance (NGA) introduces a highly scalable, cost-effective architecture for cross-device flow generation in today's high-performance data centers. Built on best-in-class Cisco Unified Computing System (Cisco UCS ) C220 M3 hardware, the NGA 3240 (Figure 1) generates, unifies, and exports flow data, empowering network operations, engineering, and security teams to boost network operations excellence, enhance services delivery, implement accurate billing, and harden network security.

Features and Benefits

Cisco NGA is a purpose-built, high-performance solution that helps enable 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/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 Cisco Nexus ® 7000, Cisco Nexus 5000, Cisco Nexus 3000, 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], IPFIX) to multiple collectors concurrently providing 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).

The key feature and benefits of Cisco NGA are described in Table 1.

Feature

Benefit

Purpose-built appliance

• Meets the rigorous performance demands of high-speed data centers.
• Achieves 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 seamlessly 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, while a billing application would be interested in specific application traffic terminating on select endpoints.
• Effective deployment design to maximize collection scalability.

Advanced filters for custom exports

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

Layer 2/Layer 3 NetFlow support

• Creates a comprehensive view of traffic flows in the data center.

Up to 80 million active flow cache entries

• Mitigate the risk of compromising accuracy as a result of the cache becoming full.
• Scale to a variety of traffic profiles with a mix of short-lived 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 configuration

• Configure the product quickly with an easy-to-use graphical user interface.

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.

Management

Cisco Integrated Management Controller (IMC) is a built-in management service available with the Cisco NGA 3240. IMC uniquely 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 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/ISO install.

Platform Support/Compatibility

Cisco NGA 3240 can be deployed with any Cisco network device that can be configured as a SPAN data source. The "managed device" feature is supported with platforms indicated in Table 2.
