Cisco Prime Network Analysis Module Software 5.1 Data Sheet

Network administrators need multifaceted visibility into the network and application to help ensure consistent and cost-effective delivery of services to end users. Knowing how traffic over the network is being used and how it is performing is essential for managing and improving the delivery of your business-critical applications. It 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.

Cisco Prime^™ Network Analysis Module (NAM) Software offers integrated network and application visibility (Figure 1) that empowers network administrators to optimize network resources, troubleshoot performance issues, and help ensure a consistent end-user experience. The software delivers granular traffic analysis, rich application performance metrics, comprehensive voice analytics, and deep insightful packet captures to help you manage and improve the operational effectiveness of Cisco^® borderless networks and the Cisco data center.

●   Interactive reports: Offers prepackaged dashboards (Figure 3) with embedded workflows and capabilities such as advanced filters, contextual navigation, and one-click packet captures to simplify monitoring and accelerate troubleshooting.

●   Site-based monitoring: 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. The feature facilitates tracking site-specific service-level objectives, resolving performance issues, or enforcing optimization policies.

●   Application Performance Intelligence: Analyzes TCP-based application packets as they travel from the client through the network to the data center and out again, providing transaction-aware analytics to help characterize the end-user experience and isolate application response time problems to the network, server, or the application itself.

●   Voice quality analysis: 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 Recommendation G.107, offering accurate characterization of voice quality. Combine monitoring with real-time troubleshooting using prepackaged dashboards to improve end-user service levels.

●   Cisco Performance Agent (PA) reporting: Provides visibility into application response time and traffic statistics at the remote branch utilizing the Cisco PA supported on ISR 880, ISR 890, and ISR second-generation (G2) platforms with Cisco IOS^® Software Release 15.1(4)T. Deployed with WAAS Express, this features allows an end-to-end view into the WAN-optimized network, delivering a cost-effective and scalable solution.

●   Flow- and packet-based traffic monitoring: Identifies what applications are running over the network, how much network resources are consumed, and who is using these applications and resources. Provides real-time and historical reports offering traffic statistics related to applications, hosts, conversations, differentiated services code point (DSCP), and VLANs.

●   Web-based captures for deep, insightful data analysis: Captures the packets to help resolve acute problems. Captures can be performed using a web browser from any desktop. Extensive capture features, including trigger-based captures, decodes, filters, and Packet Capture Error Scan, help to quickly pinpoint and resolve problem areas.

●   Standards-based API: Facilitates integration with customer in-house managed applications or third-party reporting vendor of choice. Eases configuration and export of computed NAM data, building up additional value and building out existing investments. Cisco Prime NAM Software 5.0 introduced the Representational State Transfer (REST)/XML-based API for configuration and NetFlow Version 9 for data export.

●   Anytime, anywhere access: Enables web-based access 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.

Benefits Summary

Cisco Prime NAM Software establishes a new landmark in terms of the ability to get to the appropriate information quickly, 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 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 migration from physical servers to virtual machines.

Enhance operational efficiency with faster problem detection and resolution

Cisco Prime NAM Software accelerates problem isolation and root-cause analysis, reducing the time it takes to resolve a performance issue from weeks and days to hours and minutes. The new graphical user interface (GUI) includes prepackaged dashboards with intuitive features, such as interactive reports, contextual navigation, and one-click packet captures that helps to expedite the problem resolution process. The embedded workflows allow you to isolate application problems to the network, the application, or the server. NAM identifies the client endpoints being affected by the performance degradation and the servers that could be the cause of response time delay (Figure 4). The network problems can be further investigated using comprehensive traffic analysis views with detailed information on VLANs, Differentiated Services (DiffServ), hosts, conversation pairs, and application usage. Pinpointing the traffic of interest, you can use packet-based data to perform a "deeper dive" to quickly spot and address issues that affect performance. Operational productivity can be further improved with the use of the Packet Capture Error Scan feature that highlights observed packet-level anomalies, eliminating the cumbersome task of manually analyzing the entire packet capture.

Simplify the delivery of applications and services

Managing application performance entails full visibility across all stages of application delivery, such as profiling, baselining, control, optimizaton, and troubleshooting. Cisco Prime NAM Software implements application performance analytics that can not only characterize the end-user experience but also provide performance visibility across the entire application delivery cycle. It offers you a comprehensive set of transaction-based statistics such as response time, transaction time, data transfer time, and retransmission time. It allows you to monitor and analyze application performance trends for TCP-based business applications and preempt performance issues by enabling threshold-based proactive alerts. The performance data can be rolled up and segregated on the basis of sites that you can create to mirror your network topology. Site-based monitoring can be used not only to track service-level objectives tied to specific sites but also to help to quickly isolate and resolve performance issues, minimizing any impact to the end users at the site.

Gain the most from WAN-optimization initiatives

Cisco Prime NAM Software offers end-to-end application performance visibility in the WAAS environment. The visibility empowers you to effectively use Cisco WAAS to improve application performance. It measures and reports on application response time, transaction time, bandwidth usage for optimized and pass-through traffic, and LAN/WAN data throughput among other performance metrics across all WAAS segments. The software will identify candidate sites and applications that will benefit the most with WAN optimization while quantifying and validating the impact of WAAS on application and network performance. The real-time visibility can also be used for ongoing optimization improvements and troubleshooting performance degradation issues. Figure 5 illustrates the impact of Cisco WAAS on the application transaction time.

Improve voice service levels with superior voice quality analytics

Convergence of voice and data over a shared network infrastructure offers a new set of challenges in managing voice quality. Voice is a real-time application and is highly sensitive to network parameters such as packet loss and jitter. Cisco Prime NAM Software can analyze voice streams in real time to provide critical performance information, including MOS values, to monitor voice quality. The software can also quickly identify the sites, endpoints, and RTP streams with the lowest observed voice quality, providing actionable information to further investigate the performance issues. Cisco Prime NAM Software offers a number of capabilities that can be utilized for troubleshooting voice quality degradations and improving the end-user experience. For example, NAM provides visibility into QoS/DiffServ reports to help validate QoS planning assumptions and to quickly isolate voice performance degradations possibly due to the impact of other non-business-critical applications.

Extend operational visibility into the virtual switching layer

As mission-critical workloads migrate to virtual servers, visibility into the virtual switching infrastructure becomes critical to manage end-to-end service delivery. Cisco Prime NAM Software provides operational insight into Cisco Nexus 1000V deployments to simplify manageability of the virtual switching infrastructure. It helps enable you to troubleshoot performance issues with extended visibility into VM-to-VM traffic, virtual interface statistics, and application response times. Analyzing the network usage behavior also helps to improve effectiveness of the network to support events such as dynamic resource allocations and virtual machine migrations.
