Q. Why deploy Cisco NAM in the branch?
A. The value propositions of deploying Cisco Branch Routers Series NAM include:

• Characterizing the end-user experience in the borderless access network, the place in the network closest to the end users. Deployed in the branch, Cisco NAM can provide full visibility into the traffic entering or leaving the branch, offering comprehensive views of how users are experiencing the delivery of voice, video, and TCP-based applications.

• Profiling all traffic in and out of the branch to help plan for and verify changes in network resources, such as new application rollouts, WAN optimization, server consolidation, VoIP and video deployments, and so on. Cisco NAM deployed in the branch singularly offers visibility into both branch-to-data-center traffic and branch-to-branch traffic.

• Performing VoIP quality and video stream analysis. Deployed in the branch, Cisco NAM analyzes both Real-time Transport Protocol (RTP) streams and associated signaling traffic to facilitate both timely and comprehensive reporting of voice and video quality.

• Troubleshooting application performance issues locally and remotely. The Cisco Branch Routers Series NAM provides extensive packet capture features, including trigger-based captures, decodes, error scans, and filters, to help quickly pinpoint and resolve problem areas. The feature can be used remotely to troubleshoot a branch from a centralized location, eliminating the need to send personnel to the branch or haul large amounts of data over WAN links to a central site.

Q. How does Cisco Branch Routers Series NAM work?
A. Cisco Branch Routers Series NAM receives copies of packets in a passive or promiscuous mode from the router backplane or from an external Gigabit Ethernet interface. The NAM parses the packets to gather relevant data and then stores the processed information in the new Performance Database. The database provides valuable traffic information on voice, video, and data traffic, VLANs, DiffServ configurations, hosts, conversation pairs, application usage, and application response times. The information is presented in the NAM's Traffic Analyzer GUI in easy-to-read interactive reports. It can also be exported to third-party or in-house reporting applications using NetFlow v9.
Q. What is Cisco NAM Traffic Analyzer?
A. The Cisco NAM comes with the Traffic Analyzer application. This embedded application offers an intuitive web-based graphical user interface (GUI) that includes pre-packaged reports, workflows and contextual drill-downs to expedite problem resolution and optimization decisions. The GUI also provides quick access to the configuration menus and interactive performance reports on voice, video, and TCP-based traffic. In addition, the Traffic Analyzer application hosts an embedded web server that enables remote access from anywhere so that network performance can be viewed, managed, and improved at any time, eliminating the need to travel to remote sites or haul large amounts of data over WAN links to a central site.
Q. Where is Cisco Branch Routers Series NAM deployed?
A. Cisco Branch Routers Series NAM is deployed in the Cisco 2800, 2900, 3700, 3800, and 3900 Series Routers at WAN edges or at remote branch offices. It uses features of both local and remote switches and routers to provide combined visibility into WAN and LAN traffic in the borderless access network. Traffic from selected WAN ports can be copied by the router using a special packet-monitoring feature in Cisco IOS ® Software and then sent by an internal backplane interface to Cisco NAM for analysis. Traffic from LAN ports in the router or from nearby switches can be sent to Cisco NAM through an external Gigabit Ethernet interface. By using the web-based Traffic Analyzer embedded in Cisco NAM, network managers can perform remote traffic analysis, performance monitoring, and troubleshooting without having to send personnel to remote offices or haul large amounts of data across the WAN to the central site.
Q. What branch router models support the second-generation Cisco Branch Routers Series NAM?
A. The second-generation Cisco Branch Routers Series NAM, NME-NAM-80S and NME-NAM-120S, is supported on the branch router models indicated in Table 3. An NM Adapter Card is required to successfully integrate the NME-NAM into Cisco 2900 Series and Cisco 3900 Series ISRs.

Re-inspired User Experience

NAM software 5.0 introduces a next-generation GUI that helps accelerate troubleshooting and optimization decisions by providing access to critical information at your finger tips. It offers "out-of-the-box" dashboards to give you a comprehensive graphical overview of network performance. It also includes pre-packaged interactive reports with helpful features such as contextual drill-downs, advanced filters and one-click packet captures. The new GUI not only reduces 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.

Flexible Site-based monitoring

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.

Historical analysis with embedded Performance Database

The Cisco NAM's new Performance Database stores computed data so you can go back to the past to troubleshoot un-anticipated performance issues, or to analyze optimization needs.

Pre-packaged Analysis Workflows

Pre-packaged workflows help to streamline and accelerate problem resolution. Not only do they improve operational efficiency, they also validate and improve optimization decisions.

NetFlow and Packet Data analysis in one box

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 the traffic to see 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 performance-impacting issues.

NBAR-based application recognition

The Cisco NAM now supports standardized application identifiers generated by Network-based Application Recognition (NBAR) to help deliver consistency to application recognition across the network.

Packet Capture Error Scan

The new packet Capture Error Scan automatically 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".

NetFlow v9 Data Export

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.

Q. If the NAM platform that I have is not supported, what options exist to enable me to use NAM 5.0 Software?
A. As indicated in the Answer above, NAM Software 5.0 is supported on NAM hardware platforms that include at least 1 GB of memory. If you have either of the two End of Sale NAM hardware platforms indicated below that include less than 1 GB of memory, Cisco recommends the following:

• For WS-SVC-NAM-1 (Cisco Catalyst 6500 Series NAM-1): Consider upgrading the memory to 2 GB by purchasing the field-installable Cisco Catalyst 6500 Series NAM-1 and NAM-2 Memory Upgrade Kit, MEM-C6KNAM-2GB=.

• For NME-NAM-80S (Cisco Branch Routers Series NAM): Consider taking advantage of the Cisco Technical Migration Program (CTMP) to trade-in your NME-NAM-80S NAM for a NME-NAM-120S NAM and protect your existing investment. The -120S NAM platform, which replaces the -80S, is available on supported Cisco ISR and ISR G2 routers.

Q. Will I be able to perform software upgrade from NAM 4.x to NAM 5.0 or do I need to freshly install NAM software 5.0?
A. NAM software 5.0 introduces a new embedded performance database and a new internal data schema. As a result, a fresh install will be needed.
Q. Will I lose any data when I migrate from NAM 4.x to NAM software 5.0?
A. Since NAM software 5.0 introduces a new "backend", installing NAM software 5.0 will result in loss of data and configuration settings. The configuration settings can be exported prior to upgrade and re-imported after the upgrade to minimize the loss. The "config upload" and "config network" commands to perform these tasks are documented in the command reference guide. Note that some of the configuration settings are no longer applicable.

Hardware Features

Q. How does the router send traffic to the Cisco Branch Router Series NAM internal interface?
A. The host router forwards traffic from user-selected interfaces to Cisco NAM using the router's internal PCI bus. Both inbound and outbound traffic are forwarded to Cisco NAM.
Q. Can Cisco Branch Routers Series NAM monitor traffic on multiple LAN or WAN interfaces simultaneously?
A. Yes, it can be used to monitor traffic from multiple interfaces within the router. Traffic statistics are processed and displayed using the following data sources on the module: NetFlow-based data sources and the two Cisco NAM interfaces - internal and external.
Q. Can packets be sent to the NAM before the traffic is encrypted (that is, IP Security [IPsec]) on the interface that I wish to monitor?
A. Yes. Packets are copied to the NAM by Cisco Express Forwarding. If the router is the endpoint of the IPsec tunnel, the packets will be decrypted before they reach Cisco Express Forwarding; the outgoing packets will be processed by Cisco Express Forwarding before they're encrypted. In this scenario Cisco Express Forwarding can copy the decrypted packets to the NAM for analysis.
Q. Is Cisco Branch Routers Series NAM restricted to a particular slot in the branch router chassis?
A. No. Cisco NAM can be inserted into any of the network module slots in the branch router chassis. Only one Cisco NAM is supported in each chassis.

Q. What Cisco NAM software version does the latest Cisco Branch Routers Series NAM, NME-NAM-120S, support?
A. The Cisco Branch Routers Series NAM, NME-NAM-120S, is first introduced in Cisco NAM Software 3.6.1b. It supports NAM Software 3.6.1b or later.
Q. Are all of the features included in Cisco Catalyst 6500 Series and Cisco 7600 Series NAMs also included in Cisco Branch Routers Series NAM?
A. All of the Cisco NAMs offer a common user experience, but some functional disparities exist because of the distinctions in the capabilities of both the host platforms and the NAM hardware platforms. For example, Remote SPAN (RSPAN) and Encapsulated RSPAN (ERSPAN) configurations are unique to the Catalyst switches and are not supported on the branch routers.
Q. What versions of NetFlow does Cisco Branch Routers Series NAM support?
A. Cisco NAM supports versions 1, 5, 6, 7, 8, and 9.
Q. Can NetFlow Data Export (NDE) be collected from remote WAN routers?
A. Yes, Cisco Branch Routers Series NAM can collect and analyze NDE from remote devices, including WAN routers.
Q. Does the Cisco NAM perform historical traffic analysis?
A. Yes, NAM 5.0 takes you back to the past to understand what happened when an event affecting network performance occurred. It supports historical data analysis to accelerate problem resolution, advance optimization and capacity planning decisions.
Q. What is the REST/XML API and how does it help me?
A. The NAM API provides a mechanism for provisioning and retrieving data from the NAM server using an eXtensible Markup Language (XML) interface. The API utilizes the Representational State Transfer (REST) methodology to execute requests (web services) over HTTP or HTTPS by sending the XML data to the API server. The REST XML interface is capable of configuring a subset of the software features through create, read, update, and delete operations mapped to a particular HTTP or HTTPS method. APIs are provided for sites, data sources, application, application groups, action, threshold, packet capture, WAAS monitored server, system info, and NetFlow data export. The interface also enables you to create an outgoing stream of exported performance data from NAM as NetFlow records.
Q. Is SNMPv3 supported in NAM 5.0?
A. With NAM 5.0, you have the ability to manage devices with SNMPv3. Note that for the WS-SVC-NAM-1 and WS-SVC-NAM-2 platforms, SNMPv3 is not required. SNMP requests and responses are communicated over an internal interface within the chassis, and SNMPv3 is not used.
Q. How can I recognize and configure applications reported as unknown by NAM?
A. NAM recognizes applications on the basis of port number, port number range or standardized application identifiers exported by Cisco platforms with NDE. If NAM is not able to recognize an application using any of these mechanisms, the application type of the traffic is reported as "unknown". You can configure the application reported as "unknown" using the Application configuration table on the Traffic Analysis dashboard (Analyze->Traffic-Application). When selecting an "unknown" application, the table will list all protocol/port combinations that were not recognized by NAM, and allow you to configure them as custom applications.
Q. Can I define my own application or application groups?
A. NAM identifies applications/protocols based on the TCP/UDP port number, thus, if there are any applications using custom ports, the NAM can be configured to identify those applications by name instead of by port number(s). Custom applications can be defined combining a select protocol with port or port-range definitions. Custom application groups can be defined as a set of existing applications that can be monitored together. Please refer to NAM software 5.0 User Guide (Chapter 2) for instructions on how to create a custom application or application group.
Q. How can I understand various response time metrics and how do they help me in troubleshooting application performance issues?
A. Please refer to NAM software 5.0 User Guide (Chapter 3).
Q. Why do I need custom filters for interactive reports?
A. Interactive reports use advanced filters to enable you to focus on information of interest and create a context for further analysis. For example, when analyzing application performance, you can create a filter to focus on a select site, application, time range, client, server or a combination of the foregoing, offering a powerful mechanism to isolate performance issues. In addition, the custom filter allows you to save a specific context for on-going analysis. Typically, this is valuable when watching a recurring performance issue. In such cases, you would create a custom filter having the appropriate filter attributes. When you select the custom filter, the interactive report will load the data as per the context defined in the custom filter.
Q. Can more than one user concurrently use NAM?
A. Cisco NAM allows multiple users to access NAM concurrently. Note though that the increase in the number of concurrent users can result in a below optimal user-experience in terms of interface response times.
Q. When would I define a site using data sources or vlans?
A. NAM software 5.0 introduces the concept of logical sites as collection of network end-points. A site can be defined as a set of subnets specified by an address prefix and mask. In addition, a site can be defined using a remote device data source (such as remote WAAS device, NDE from remote network device) or VLAN(s). As examples, a site can be defined as a remote WAAS device representing the collection of end-points for which an application is being optimized, or in the case of managed service delivery, a site can be defined as a VLAN representing a customer premise. A combination of these mechanisms offers a granular way to define a site.
Q. How many simultaneous captures does the NAM support?
A. Cisco NAM can support up to 10 simultaneous packet capture sessions.
Q. How can I replicate my site definitions and application definitions across all my NAMs?
A. The REST/XML API introduced with NAM software 5.0 allows you to create, update and delete site definitions. It also allows you to retrieve all site definitions from a given NAM. Using these functions you can replicate site definitions programmatically across all NAMs deployed in the network. A similar API exists for the definitions of application and application groups.
Q. How is Cisco NAM Traffic Analyzer secured?
A. The Cisco NAM Traffic Analyzer can be secured with up to 256-bit encryption. This requires users to download a K9-designated patch for the NAM software from the Cisco.com Software Center. Cisco NAM also supports role-based user authorization and authentication locally or using TACACS+.
Q. What MIBs are supported on Cisco Branch Routers Series NAM?
A. Cisco Branch Routers Series NAM is standards-compliant and support the following major MIB groups:

• MIB-II (RFC 1213) - All groups except Exterior Gateway Protocol (EGP) and transmission

• RMON (RFC 2819) - Alarm and Event groups only

• RMON2 (RFC 2021) - trapDestTable only

• Cisco Discovery Protocol (CDP)

• EntityMIB (RFC 2737)

Q. Does Cisco NAM support voice monitoring for Cisco VoIP deployments only?
A. No. Cisco NAM monitors Real-time Transport Protocol and thus, by extension, can provide reporting on any VoIP protocol that runs on top of RTP, a Layer 4 protocol.
Q. Which VoIP signaling protocols does the Cisco NAM support?
A. Cisco NAM supports a breadth of VoIP signaling protocols, namely, Skinny Client Control Protocol (SCCP), Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), and H.323.
Q. What are the key performance indicators for monitoring voice?
A. Cisco NAM offers real-time voice quality monitoring using standards-based Mean Opinion Score (MOS) and key performance indicators such as jitter and packet loss. It calculates MOS based on ITU-T G.107 recommendations.
Q. Can I identify the phones affected due to voice quality degradation?
A. Yes. Cisco NAM allows the administrator to pinpoint the individual RTP stream experiencing voice quality degradation. By correlating the RTP and signaling streams, Cisco NAM can report the phone numbers and alias for each endpoint.
Q. What Cisco Unified Communications Management Solutions support NAM?
A. The solutions are Cisco Unified Service Monitor and Cisco Unified Operations Manager.
Q. How do Cisco Unified Service Monitor and Cisco Unified Operations Manager support NAM?
A. Cisco Unified Service Monitor collects voice metrics from multiple NAMs to provide enterprisewide visibility into voice quality. Cisco Unified Service Monitor generates alerts on voice quality degradation that is reported by Cisco Unified Operations Manager. Based on these alerts, Cisco Unified Operations Manager helps enable the user to navigate into NAM to glean near real-time views of both voice and network performance to perform rapid troubleshooting.
Q. How does Cisco NAM support Cisco Wide Area Application Services?
A. Cisco NAM uses the built-in instrumentation of the Cisco Wide-Area Application Engine (WAE) devices as a data source to gather information on the optimized traffic to provide end-to-end application performance visibility in a Cisco WAAS environment. It measures application response time, transaction time, bandwidth usage, LAN/WAN data, and so on to provide end-to-end application performance metrics, accurately quantifying the impact of WAAS optimization and helping to validate ongoing optimization improvements. NAM is also able to identify the applications that would benefit the most from deploying Cisco WAAS. Analyzing response time data over a period of time, the administrator can identify the applications for which optimization can result in a material increase in available bandwidth.

Third-Party Reporting

Q. Does Cisco NAM include an API to allow third-party reporting applications to use NAM as a source of data?
A. Yes, the Cisco NAM includes multiple mechanisms, such as NetFlow V9, SNMP and comma-separated value (CSV)/HTTP to enable third-party reporting applications to collect data for networkwide reporting, trending, baselining, and capacity planning. The API 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. NAM 5.0 introduces XML/REST-based API for NAM configuration and NetFlow v9 as a flexible and standard mechanism for data export.
Q. How can a third-party apply for approval to use the Cisco NAM API for integration?
A. A third-party can enroll in the Cisco Developer Network at http://www.cisco.com/go/cdn. During the enrollment process, the third-party must select Network and Service Management as the solution technology and Cisco NAM as the network management product for integration. Once approved and the nondisclosure agreement (NDA) and NAM developer license agreement signed, the third-party will receive the API for integration.
Q. Are there currently third-parties who have joined this program? How can a list of these vendors be obtained?
A. Yes. Today, reporting applications from third-parties such as NetQoS, Compuware, Infovista and others offer support for NAM. These reporting applications complement the NAM by using its rich metrics to build end-to-end views of application usage and performance and also to streamline the number of collection points in the network. A list of third-parties supporting NAM can be found at http://www.cisco.com/go/cdn under Find a Partner, Network and Services Management, and Network Management Services Modules.
