It all comes down to knowing. Knowing who is using the network, knowing what applications are running on the network, knowing how the network is performing, knowing how traffic over the network is being used and how it is performing are the foundation for managing and improving the delivery of your business-critical applications. Knowing is the foundation for establishing and verifying quality of service (QoS) policies, undertaking WAN optimization projects, and rolling out voice over IP (VoIP). It is also the foundation for recognizing when a configuration change has unintentionally degraded application performance or for providing proof points that it is the application and not the network that is causing one of your business planning systems to perform poorly so that the appropriate actions can then be taken.

Product Overview

The Cisco Branch Routers Series Network Analysis Module (NAM) helps you know. It is your source for unparalleled network and application visibility, analyzing traffic flows between users and their critical applications to help you ensure that the network performs to the rigorous demands of the business. And, when there's a problem, the Cisco NAM can help you find it fast, reducing the time it takes to resolve it from days to just minutes.

As a member of the Cisco NAM portfolio of products, the Cisco Branch Routers Series NAM provides granular traffic analysis, rich application performance metrics, comprehensive voice analytics, and deep insightful packet captures to help you manage and improve how your users experience the delivery of applications and services in your Cisco Borderless Network. Its unique design combines embedded data collection and analysis capabilities with a remotely accessible, web-based management and reporting console, all of which reside on a single blade that is installed into the Cisco Integrated Services Routers (ISR) and ISR Generation Two (G2) family of routers.

Figure 2. Cisco NAM Traffic Summary Dashboard
The Cisco Branch Routers Series NAM includes a snappy graphical user interface (GUI) with dashboards (Figure 2) to give you an immediate view of network performance and workflows to help you simplify problem detection and resolution. It also uses a rich set of Cisco infrastructure features as sources of data, such as Cisco Express Forwarding copies of packet data and NetFlow, giving you more ways to see and understand what's happening on your network. And, with an array of vital features and functions, such as a new Performance Database, which preserves historical data, allowing you to understand what happened in the past when an event that affected network performance occurred, the Cisco NAM makes it easier than ever before to manage and improve network and application performance anytime and anywhere.
The Cisco Branch Routers Series NAM is the glue binding your Cisco Borderless Network deployments, providing application visibility within the branch, between branches, and between the branch and data center. Cisco NAM deployed in the branch provides end-to-end visibility for branch-to-branch applications, such as voice, and for TCP-based applications hosted in the data center, driving application delivery consistency and efficiency across the network.

Infrastructure integration

Deployed in the Cisco ISR and ISR G2 routers, the Cisco NAM provides greater investment protection, lower total cost of ownership, and a reduced footprint to save premium rack space.

Application performance intelligence

Characterize the end-user experience for TCP-based applications and isolate application response time problems to the network, server, or the application minimizing any triage process.

Comprehensive voice quality monitoring and real-time troubleshooting

Gather real-time reports on Mean Opinion Score (MOS) and other key performance indicators (KPIs) such as jitter and packet loss to understand and improve how the end user experiences the delivery of voice services. MOS is computed based on ITU-T Recommendations G.107 offering accurate characterization of voice quality. Combine monitoring with real-time troubleshooting using pre-packaged dashboards to improve the end-user service levels.

WAN optimized networks visibility

Obtain end-to-end proof points demonstrating how WAAS has improved application delivery (for example, decreased application transaction times, improved WAN bandwidth utilization). Accelerate the ROI for your investment by assessing the best site and application candidates for optimization as part of the phased roll-out plan.

Detailed traffic analytics

View short- and long-term performance data on hosts, conversations, and applications that use critical network resources.

Historical analysis

Look back to the past with the embedded Performance Database to understand what happened when an event that affects network performance occurred to accelerate root-cause analysis and prevent any reoccurrence. Use historical analysis for advancing optimization and capacity decisions.

Deep, insightful packet captures

Use capture features, such as trigger-based captures, filters, decodes, and Packet Capture Error Scan, to increase troubleshooting agility.

Nexus 1000V deployment visibility

Simplify the operational management of Cisco Nexus 1000V switch environments by gaining visibility into the virtual machine (VM) network including interactions across virtual machines and virtual interfaces. Monitor the VMs uninterrupted by vMotion operations.

Pre- and postdeployment metrics

Glean valuable before and after traffic analytics to help plan for and verify changes in network resources, such as introducing new applications, establishing QoS policies, consolidating servers, and deploying VoIP.

Open interface

Ease NAM configuration and export of computed NAM data using standards-based APIs (XML/REST for configuration, NetFlow Version 9 for data export).

Anytime, anywhere access

Access the embedded web interface from any desktop, eliminating the need to send personnel to remote sites or haul large amounts of data over WAN links to the central site.

Monitoring interfaces

Two monitoring interfaces: One internal backplane interface for receiving a copy of WAN traffic through the Cisco Express Forwarding copy packet monitoring feature in the router's Cisco IOS Software and one external Gigabit Ethernet interface for receiving traffic directly from local or remote LAN ports. Either can be used for management traffic, for receiving NetFlow data, or for receiving flow agent data from Cisco WAAS.


Using the internal monitoring interface, traffic monitoring throughput of up to 100 Mbps has been benchmarked for the NME-NAM-120S installed in Cisco 3900 Series and Cisco 3800 Series ISRs, and up to 45 Mbps in Cisco 2900 Series and Cisco 2800 Series ISRs. The external monitoring interface has been benchmarked to support up to 200 Mbps throughput monitoring. Your monitoring performance may differ based on factors such as packet size, traffic burstiness, collections enabled on the NAM, and features enabled on the router. Contact your Cisco sales representative to obtain further information about NME-NAM-120S performance characteristics.
