8.3.2 RMON1 Groups and Functions RMON1 performs numerous functions at the data link layer.Figure 8.3 depicts the RMON1 groups and functions.The data gathering modules,which are LAN probes,gather data from the remotely monitored network comprising Ethernet and token ring LANs. The data can serve as inputs to five sets of functions, three of which monitor traffic statistics.The host and conversation statistics group deals with traffic data associated with the hosts,ranking the traffic for the top N hosts,and conversation between hosts.The group of statistical data associated with Ethernet LAN-namely, Ethernet statistics and Ethernet history statistics-is addressed by the groups and functions in the Ethernet statistics box.The history control table controls the data to be gathered from various networks
