Cisco® Catalyst® 6500 Series and Cisco 7600 Series Network Analysis Module (NAM) is a powerful network-aware performance assurance solution that delivers unparalleled visibility into application and network performance to help ensure the consistent and efficient delivery of applications and services to the end users.
Cisco Catalyst 6500 Series and Cisco 7600 Series NAM combines performance monitoring, traffic analysis, and advanced troubleshooting to meet the performance assurance needs of today's dynamic, evolving enterprises. It is designed to provide deeper insight at both the network and application levels. It offers real-time visibility into the applications running on the network, how the network resources are being utilized, and how the end users experience these applications. The visibility also allows IT to effectively use control and optimization mechanisms such as quality of service (QoS) and Cisco Wide Area Application Services (WAAS) to improve the performance of applications and services.
The unique design of Cisco NAM combines a rich set of embedded data collection and analysis capabilities with a remotely accessible, web-based management console, all of which reside on a single blade (Figure 1) that is easily installed into the Cisco Catalyst 6500 Series Switch or the Cisco 7600 Series Router.
As an integrated services module, Cisco NAM uses a rich set of Catalyst 6500 Series Switch and Cisco 7600 Series Router features to collect both LAN and WAN traffic for analysis. Using the Switched Port Analyzer (SPAN) feature, Cisco NAM can monitor traffic from physical ports, virtual LANs (VLANs), or Cisco EtherChannel connections of the local switch or router. Using VLAN access control list (VACL)-based captures, traffic can be filtered before it is sent to Cisco NAM to support the selective monitoring of large amounts of traffic or the gathering of traffic from WAN interfaces. In addition, Cisco NAM can consume NetFlow Data Export (NDE) from local and remote devices to provide both real-time and historical traffic usage data. Cisco NAM can also use the Remote SPAN (RSPAN) or Encapsulated Remote SPAN (ERSPAN) features of the devices to extend troubleshooting to remote parts of the network. By supporting these Catalyst 6500 Series and Cisco 7600 Series features, Cisco NAM offers more ways to see and understand what's happening on the network. Cisco NAM offers extensive monitoring capabilities to meet diverse network analysis needs in scalable switching and routing environments.
