generation. Information provided by RMON can be used for identifying sources of network problems, for fine-tuning network performance, and planning for network expansion.

RMON uses SNMP for communication between the network management station and RMON agents. Unlike SNMP devices, RMON keeps polling traffic overhead to a minimum as the RMON probes are not continuously polled.

Note

RMON provides a lot of statistical data detailing the network operations at the media level. This information, though very useful, should be used in the context of the nature of the activities occurring in the network. They should be used in assisting further investigations. For instance, when RMON reports a high packet rate and high utilization, we need to investigate further what is the nature of the traffic that caused those statistics to rise significantly. Are those data packets or non-data packets? Non-data packets require further investigation while data packets could simply result from someone performing a large file transfer.

10.1.1 Network Probes

The implementation of RMON requires network probes to be installed on each managed LAN segment throughout the enterprise network as depicted in Figure 116 on page 193. These network probes are devices whose resources are dedicated to managing the LAN segments they are attached to. Resources required by these network probes are very much dependent on the number of devices in the segment to be managed, traffic flow, type of data to be collected, frequency of collection, multiple manager requests, etc. Usually, one probe per segment is recommended for monitoring and data collection.

Network probes can be stand-alone specialized probes, integrated hub/bridge/router agents, or RMON agent software running on workstations. A subset of the RMON MIB must be present on these devices to function as an RMON agent. RMON agents can be found in bridges, routers, and hubs. Bridges and routers are not recommended as RMON agents as their primary roles are to get the traffic moving without imposing additional overhead.

10.6, ªMonitoring Functions Supported In 8260º on page 212 discusses the RMON agents implemented in the 8260 DMM (along with T-MAC and E-MAC daughter cards).
