Part Code: WS-SVC-NAM-2-250S Manufacturer: Cisco Device Type: Network monitoring device Enclosure Type: Plug-in module Dimensions (WxDxH): 35.6 cm x 40.6 cm x 3 cm RAM Installed ( Max ): 2 GB Cisco Catalyst 6500 Series and Cisco 7600 Series Network Analysis Module 3.6
Cisco® Catalyst® 6500 Series and Cisco 7600 Series Network Analysis Module (NAM) is a powerful network-aware performance monitoring solution that delivers unparalleled insight into network traffic to help you ensure the consistent and efficient delivery of applications and services to your end users. Product Overview Cisco Catalyst 6500 Series and Cisco 7600 Series NAM is a powerful performance monitoring solution designed to give you more visibility into your network than ever before. It shows you how the network is being used and how your users experience the services the network offers to help you improve network and application performance. Because Cisco NAM provides visibility for comprehensive performance analysis and simplified troubleshooting, it is ideally suited for today's dynamic, evolving enterprises.
The innovative 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 that is easily installed into the Cisco Catalyst 6500 Series Switch or the Cisco 7600 Series Router. Cisco NAM is available in two hardware versions, NAM-1 and NAM-2 (Figure 1) and offers extensive monitoring capabilities to meet diverse network analysis needs in scalable switching and routing environments. Cisco NAM includes a Traffic Analyzer GUI, which provides quick access to the configuration menus and presents easy-to-read performance reports on web, voice, and video traffic.
Figure 1. Cisco Catalyst 6500 Series and Cisco 7600 Series Network Analysis Modules, NAM-1 and NAM-2  Applications Visibility throughout the Infrastructure 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 you more ways to see and understand what's happening on your network.
Easy to Deploy and Use Cisco NAM includes an embedded, web-based Traffic Analyzer GUI (Figure 2) that can be accessed from any desktop, eliminating the need to send personnel to remote sites or haul large amounts of data to the central site. It delivers a complete view of network and application performance, providing essential information on voice, video, and data traffic, VLANs, Differentiated Services (DiffServ) configurations, hosts, conversation pairs, application usage, and application response time. To enhance security, role-based access can be assigned and web-browser access can be secured with up to 168-bit encryption.
Figure 2. Web-based Traffic Monitoring with the Embedded Cisco NAM Traffic Analyzer  Monitoring the Virtualized Campus Network virtualization for the campus is a cohesive, extensible architecture to logically partition the network infrastructure. It simplifies network operations and reduces costs while increasing flexibility and agility and enhancing productivity. In today's evolved networking environments, typical campus network designs use a mix of Layer 2 switching technologies at the network edge (access layer) and Layer 3 routing technologies at the network core (distribution and core layers). Thus, network virtualization can be achieved at the network access layer (Layer 2) by means of VLANs and at the network core (Layer 3) by using Generic Routing Encapsulation (GRE) tunnels, Virtual Route Forwarding (VRF)-Lite, and Multiprotocol Label Switching (MPLS)-based Layer 3 VPNs to partition the routed domain and thus achieve scalable end-to-end virtualization.
Cisco NAM monitors traffic flowing through the virtualized campus. For designs using MPLS VPNs, Cisco NAM can identify, monitor, and capture MPLS VPN traffic. Because Cisco NAM can present detailed "before and after" traffic information, it can ease the deployment of a virtualized campus design by facilitating the critical planning and management activities required to help ensure a smooth transition.
Flexible Deployment Scenarios Cisco NAM can be deployed in the Cisco Catalyst 6500 Series at LAN aggregation points (for example, in the core and distribution layers) for proactive monitoring; at service points (for example, in data centers, or Cisco Unified Communications Manager clusters in IP telephony networks) where performance monitoring is critical; and at important access points (critical clients, IP phone closets) where quick troubleshooting is required. It can also be deployed in Cisco 7600 Series Routers at WAN edges or in Catalyst 6500 Series Switches connected to WAN routers.
