Network Analysis Modules
This chapter describes the Network Analysis Modules (NAMs) and contains the following sections:
• Network Analysis Module (WS-SVC-NAM-1), page 6-1
• Network Analysis Module (WS-SVC-NAM-2), page 6-2
NAMs monitor and analyze network traffic for the Cisco 7600 series routers using Remote Monitoring
(RMON), RMON2, and other MIBs. The RMON support that the NAM provides for Ethernet VLANs is
an extension of the RMON support provided by the supervisor engine. The switched port analyzer
(SPAN) selects network traffic and directs it to the NAM. TrafficDirector, or any other IETF-compliant
RMON application, can analyze link characteristics, packet layers for capacity planning or departmental
accounting, differentiated service deployment and policies, and filter/capture packets for debugging.
Note Specific combinations of supervisor engines and modules may not be supported in your chassis. Refer
to the release notes of the software version running on your system for specific information on modules
and supervisor engine combinations that are not supported.
Network Analysis Module (WS-SVC-NAM-1)
The Network Analysis Module (WS-SVC-NAM-1) provides integrated network monitoring services
within the router. The NAM collects network traffic statistics for real-time traffic analysis, performance
monitoring, and troubleshooting.
The NAM monitors and analyzes network traffic for the Cisco 7600 series routers using remote
monitoring (RMON), RMON extensions for switched networks (SMON), and other management
information bases (MIBs). The NAM supports the following RMON groups:
• RMON groups defined in RFC 1757
• RMON2 groups defined in RFC 2021
The NAM also can monitor individual Ethernet VLANs, which allows it to serve as an extension to the
basic RMON support provided by the supervisor engine.
You can use any other IETF-compliant RMON application to access link, host, protocol, and
response-time statistics for capacity planning, departmental accounting, and real-time application
protocol monitoring. You also can use filters and capture buffers to troubleshoot the network.
The NAM can analyze Ethernet VLAN traffic from one or both of the following sources:
• Ethernet, Fast Ethernet, Gigabit Ethernet, trunk port, or Fast EtherChannel SPAN or RSPAN source
