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.

NAM Software 5.0 Innovations

NAM Software 5.0 means agility - agility that allows you quickly to know what is happening on the network and see where trouble is lurking. NAM Software 5.0 offers new and enhanced capabilities that help enable you to get to the right data fast, whether it is data that helps you respond to a help desk call on slow application performance, understand application performance before and after deploying Cisco Wide Area Application Services (WAAS), confirm that VoIP performance is rock solid at one of your international sites, or learn whether application performance has also made the leap with your server centralization and consolidated branch-office project.

Figure 3. Application Performance Troubleshooting Workflow

Redesigned GUI simplifies monitoring and troubleshooting: The Cisco NAM's redesigned GUI includes preconfigured dashboards that provide a comprehensive graphical view of network performance so you can immediately grasp whether all is well or whether a problem is emerging. It also includes workflows with helpful features such as contextual navigation, interactive reports, and one-click packet captures (Figure 3). The NAM's GUI reduces not only the time it takes to solve problems but also the time it takes to learn the product, giving you more time to spend on advancing new business initiatives.

NetFlow and packet data analysis in one box offer unprecedented levels of breadth and depth: NetFlow and packet data complement each other to provide a powerful monitoring solution, all in one box. With expanded NetFlow reporting capabilities, you can obtain an extensive view of traffic usage information, such as who is using your network, what applications they're using, and how much bandwidth is being consumed. Pinpointing traffic of interest, you can use packet-based data to perform a "deeper dive" to quickly spot and address issues that affect performance.

A Performance Database lets you flash back to the past: The Cisco NAM's embedded Performance Database stores computed, historical data so you can flash back to the past to learn what happened on your network when a particular event occurred. Only too often do these anomalous events occur and are then gone. Now, with the Cisco NAM's Performance Database, you can look back, discover the facts, and solve the problem fast.

NetFlow Version 9 Data Export extends network reporting: By exporting analytics in a standardized format, this new capability allows you to use computed NAM data to feed in-house or third-party reporting applications that you already own, building up additional value and building out existing investments.

Site-based monitoring delivers reporting flexibility: This feature allows you to view network and application performance by logical groupings or sites that you can create to mirror your network topology. For example, you can create sites by geographic locations, departments, or even managed customer networks and view performance data on a per site basis, making it easier to obtain both a global and local view of how your applications are performing.

Network-Based Application Recognition (NBAR) improves application identification consistency: The Cisco NAM now supports standardized applicaton identifiers generated by Cisco's homegrown application classification technology, NBAR, to discover and identify applications, simplifying your user experience by helping bring consistency to application recognition across the network.

Packet Capture Error Scan finds problems fast: The Cisco NAM's Packet Capture Error Scan feature highlights packet-level anomalies to accelerate root-cause analysis and avoid having to manually inspect the packet data to find the "needle in the haystack."
