Medianet Management and Visibility Design Considerations
Cisco Network Analysis Module
This document discusses only the use of the Cisco Catalyst 6500 Series Network Analysis Module
(WS-SVC-NAM-2). Specific testing was performed with a WS-SVC-NAM-2 with a WS-SUP32P-10GE
supervisor within a Cisco Catalyst 6506-E chassis. Other platforms may have slightly different
functionality. The WS-SVC-NAM-2 can analyze and monitor network traffic in the following ways:
• The NAM can analyze chassis traffic via Remote Network Monitoring (RMON) support provided
by the Cisco Catalyst 6500 Series supervisor engine.
• The NAM can analyze traffic from local and remote NetFlow Data Export (NDE).
• The NAM can analyze Ethernet LAN traffic via Switched Port Analyzer (SPAN), remote SPAN
(RSPAN), or VLAN ACL (VACL); allowing the NAM to serve as an extension to the basic RMON
support provided by the Cisco Catalyst 6500 Series supervisor engine.
This document discusses only certain functionality of the NAM as it relates to gaining visibility into
video flows within an enterprise medianet. A comprehensive discussion of the configuration and
monitoring functionality of the NAM is outside the scope of this document. For the end-user and
configuration guides for the Cisco Network Analysis Module Software, see the following URL:

NAM Analysis of Chassis Traffic
The WS-SVC-NAM-2 has the ability to collect basic traffic statistics, per interface, from the supervisor
line card within the Cisco Catalyst 6500 chassis. These statistics can be viewed as current rates or as
cumulative data collected over time. Current rate data includes statistics such as the following:
• Input and output percentage utilization of the interface
• Input and output packets/second
• Input and output bit or byte rates
• Input and output non-unicast (multicast and broadcast) packets/second
• Input and output discards/second
• Input and output errors/second.
Figure 6-5 shows an example of the monitoring output.
