Application Scenarios for RMON
On a live network, RMON implements the monitoring and statistics collection functions on a network segment. On the network shown in Figure 1, RMON Agent connects to the terminal through the console interface and to the NMS through the Ethernet. The SNMP Agent is deployed on the RMON Agent to monitor Interface 1, and the statistics function and alarm function are enabled on the interface.
- To collect traffic statistics on an Ethernet interface, realtime and historical traffic and packet statistics, monitor port usage and collect error packet data.
- To monitor the traffic bytes on the interface, you can configure the function to process an event as recording a log and set a threshold. When the traffic bytes in a minute exceed the threshold, a log is recorded.
- To monitor broadcast and multicast traffic on the network, configure the function to process an event as sending a trap message and set a threshold. When the number of broadcast and multicast packets exceeds a predefined threshold, a trap message is sent to the NMS.
