NM-NAM Architecture
Data enters the NM-NAM for analysis via one of two interfaces on the NAM, the internal and external
monitoring interfaces. One of these interfaces will also be used to receive all NAM access traffic (SNMP,
HTTP, and telnet), as well as NDE traffic. The data, received in frame format, is parsed by the RMON
process on the NAM and stored in the RMON, SMON, and other MIBs loaded onto the NAM. The polling
process grabs data from these MIBs and performs the data analysis and presentation functions that generate
the graphical tables and charts that you see. The analysis software responds to HTTP requests from a
client’s Web browser and presents the traffic reports and the configuration menus.
Note: Traffic forwarded to the Internal NAM monitoring interface is controlled by the host router.
