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 includes an embedded, web-based Traffic

Analyzer GUI (Figure 2), which provides quick access to the configuration menus and application performance views

for voice, video, and TCP-based applications. The GUI 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. To enhance security, role-based

access can be assigned and web-browser access can be secured with up to 256-bit encryption.

Features and Benefits

Intelligent Application Performance Analytics

Cisco Catalyst 6500 Series and Cisco 7600 Series NAM provides comprehensive intelligent application performance

(IAP) measurements to accurately characterize end-user experience. It analyzes the TCP-based client/server

messages to provide transaction and session-based statistics. Intelligence derived from integrated application and

network visibility helps to isolate application problems to the network, the application, or the server. It also helps to

quickly analyze the root cause and resolve problems minimizing any impact to the end users.

The Cisco NAM GUI allows network administrators to correlate the end-user experience with network performance

metrics, such as network delay, round-trip time, retransmission time, and so on, to identify the cause of degradation.

For example, the source of network latency affecting the end-user experience can be identified by analyzing network

delay metrics, namely client network delay, server network delay, and network delay. Similarly, server resource

issues can be identified by network metrics such as application delay and server response time.

Figure 3 provides an example of the application response time report for an HTTP application. The report shows

reduction in the application delay after the administrator restarted a hung process on the application server.
