Understanding How the NAM Works
The NAM monitors and analyzes network traffic for the Catalyst 6000 family switches using
remote monitoring (RMON), RMON extensions for switched networks (SMON), and other management
information bases (MIBs). The NAM supports the following RMON groups:
•
•
In addition to extensive MIB support, the NAM also can monitor individual Ethernet VLANs, which
allows it to serve as an extension to the basic RMON support provided by the Catalyst 6000 family
supervisor engine.
You can use TrafficDirector, or 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:
•
•
The NAM is managed and controlled from either the embedded web-based NAM Traffic Analyzer
application (directing a web browser at the NAM) or a Simple Network Management Protocol (SNMP)
management application, such as those bundled with CiscoWorks2000, or both.
