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 and video packet quality 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, filters, and a capture analysis toolset, 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 and extracts data to populate standards-based management information bases (MIBs) included in the NAM such as remote monitoring (RMON/RMON2) and RMON extensions. The MIBs provide valuable traffic information on voice, video, and data traffic, VLANs, Differentiated Services (DiffServ) configurations, hosts, conversation pairs, application usage, and application response times. This information is presented in the NAM Traffic Analyzer GUI in easy-to-read real-time and historical reports or can be accessed using a standards-based centralized Simple Network Management Protocol (SNMP) console.
Q. What is Cisco NAM Traffic Analyzer?
A. Cisco NAM includes embedded software, called Cisco NAM Traffic Analyzer, which analyzes and stores the data. It presents the data to clients using a supported web browser.
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.
